3 . Fu e l s t r a t e g y

The tab contains options that determine how the system is to work on high rpm, on high rpm and with aheavy load, during decelerations and on low rpm. Normally, after switching to gas, the engine is powered bythe gas until the ignition is off or the pressure drops as a result of lack of gas in the tank. However, in certainsituations described above, it is sometimes necessary to temporarily switch the engine to petrol. It can happenwhen e.g. the petrol injectors are still open or when the engine cuts out after deceleration to idle.

You will also find here an additional function designed for engine types like Mazda which change the way offuel distribution under the influence of load change.

H i g h RPM

D i s a b l e d - the system works on high rpm on gas the same as on petrol until the rpm limiter works.M a x p o w e r - the system, above the given rpm and injectors opening time, switches to petrol. After fallingbelow the preset value the system automatically returns to gas. The switch in the cab shows the normaloperation on gas, whether in the program next to the virtual switch there is indication of this function.

PDM - the system, at a given engine load, regardless of rpm, switches to petrol with automatic return to gas ata differential load. This function is useful for engines with very long petrol injectors opening times. At highrpm, there may be the case in which the injectors are still open (e.g. the opening times of 25 ms at 4800 rpmmeans that the injector is still open and the engine load is equal to 100%). The Zenit Pro ECU can for a momentcontrol gas injectors in the same way, but in this situation it is no longer able to control the mixture, thus it is

recommended (e.g. at 90% load) to switch to petrol earlier. The switch in the cab shows normal operation ongas, while in the program next to the virtual switch, there is indication of this function.

In the example here, after reaching5000 rpm if the gas injector openingtime is more than 20ms, the ECU willswitch the engine to petrol, afterfalling below the value, it will revert

back to gas.

I n t e r v e n t io n - the system above certain rpm and injectors opening time, begins to shorten gas injectorsopening times and additionally inject petrol by opening the petrol injectors to the time set in the windowP et r o l i n t e r v e n t i o n ( m s ) . The En r i c h m e n t function can also additionally increase the mixture of petrol notshortening the time of opening of the gas injectors. After falling below the preset value of rpm and time thesystem automatically returns to work only on gas. This function is used primarily to support the gas injectorsand make it more flexible and increase the dynamics of the engine on high loads. The switch in the cab showsthe normal operation on gas, while in the program next to the virtual switch, there is indication of this function.

L o w R PM

D i s a b l e - the system works on low rpm on gas.

M i n Po w e r - when the rpm fall below the threshold set by the installer ( Th r e sh o l d m i n p ow e r ( r p m ) ) thesystem switches to petrol and only if the speed increases by value ( H y s t er e s i s m i n p o w e r ( r p m ) ) it getsback to gas. The ECU always switches all the injectors at the time, return to gas depends on the settings, if inthe settings the cylinder sequential switching is chosen then the return to gas will look the same. The switch inthe cab shows the normal operation on gas, while in the program next to the virtual switch, there is indicationof this function.

R e t u r n t o p e t r o l - when the rpm fall below the threshold set by the installer ( T h r es h o ld m i n p ow e r ( r p m ) )the system switches to petrol and after the number of openings of the petrol injector set in the window ( T im e dc y c l e s ( p e t r o l ) ) it automatically returns to gas. The control panel always switches all the injectors at thetime, return to gas depends on the settings, if in the settings the cylinder sequential switching is chosen thenthe return to gas will look the same. T o a ct i v a t e t h i s f u n c t i o n , t h e s p e e d l e v e l b e f o r e t h e d e c r e a s es h o u l d e x c e e d t h e a c t iv a t i o n t h r e s h o ld b y a p p . 2 0 0 .

The switch in the cab shows the normal operation on gas, while in the program next to the virtualswitch,shows there is an indication of this function.

Ma z d a s t r a t e g y

This function is used for the engines in Mazda cars, in which under some load the way of controlling the petrolinjectors changes - the petrol controller switches from sequential system to half-sequential. Petrol injectors(and consequently the gas ones as well) start to open twice as often and for about twice as short a time (e.g.they shorten from 8 ms to 4 ms although the engine load does not change or increase). As a result of this

change, when working on gas, there appears rich mixture and ignition loss and jerking may happen. Activatingthis function allows perfect adjustment of the mixture both at low load at sequential work and under heavyload at non-sequential work. The switch in the cab shows the normal operation on gas, while in the programnext to the virtual switch, there is indication of this function.

The ECU automatically detects themoment of change engine fuel supplystrategy. The installer’s task is only to setthe right value in the window Ra t e o fl ea n in g ( % ) so that after this change,the mixture can be optimal.

Zenit Pro system has internal diagnostic tool that identifies and stores the errors occurring duringoperation of the system. On the errors tab, we can read the saved and the current errors and, after theremoval of the cause, cancel them.

You can choose which errors in the system should switch supply to petrol and also which are to bemonitored and reported by the system.

The box allows you to choose whether thecomponent is to be monitored or not.

Activating the icon (change of colourto red) leads to switching the systemto petrol after the error appearance.

Selecting the option “Enable switch signal on errordetected” causes that after recording the error in the gasECU, the switch in the cab will beep a few times and the light“CHECK” will start flashing.

the ECU reads the co

Zenit Pro OBD has an advanced internal system to connect and read the parameters from the vehicle'sOBD system. This allows dynamic correction of the mixture based on read parameters

W i r i n g t h e O BD so c k e t .

The wiring loom Zenit Pro OBD has four wires for connecting to the OBD system. These wires are to beconnected to wires within the OBD diagnostic socket.

O r a n g e - p i n 6 - CAN H

O r a n g e / b l a ck - p i n 1 4 - CAN L

Gr e e n - p i n 7 - I SO K

Gr e en / b l ac k - p i n 1 5 - I SO L

If we are not sure what OBD standard operates in the given car, the safest way is to connect all the wires to theactive pins. The system detects connection type itself. It may e.g. happen that in the socket there will be active(occupied) pins 6, 14 for CAN and pin 7 . We need to connect the wires orange, orange / black and green as itcan prove that the ECU connects to the OBD ISO standard only with a line K. Co n n e c t i o n w i t h O BD

Establishing the connection occurs immediately after the ignition is switched on, provided that the system is in"Auto" mode if, when during the ignition on system it is in "Petrol" mode, the ECU does not try to connect toOBD.

If after the ignition is switched, transmission channel is busy because the OBD socket is connected to anotherdevice (e.g. OBD scanner), the ECU goes into passive mode and no longer tries to connect until the nextignition.

Reading OBD parameters when working with petrol is possible only when car had been working on gas before,the ECU had established a connection to OBD and then was switched to petrol.

T h e g e n e r a l a l g o r i t h m o f O BD f u n c t i o n .

After ignition and connecting to OBD, the ECU checks whether all the conditions to start collecting maps andcorrection of mixture are fulfilled, i.e. whether the system is in open loop or closed loop and whether thetemperature is higher than " T em p e r a t u r e t h r e s h o l d ". Additional conditions that must be fulfilled is " R p mt h r e s h o l d " (prevents points collection at idle) and “ L o a d t h r e s h o l d " (prevents the collection of points, e.g.at low loads, at so called Pre cut-off, etc. ...... .. rrection of short- and long-term,averages them and stores in its internal "OBD corrections map". Then, on the basis of this map, it corrects themixture of gas.

O f f se t a d j u s t m e n t f u e l t r i m O BD - the value meaning the base value of the adjustment of the mixture (i.e.the one for which we seek, the ideal) usually should be zero, sometimes, in cars with high mileage, you shouldcheck what it is on petrol and in such cases may be different from zero, e.g. ...: +5

T o l e r a n c e f u e l t r i m - is the maximum difference between the currently read correction and average value" o f f s e t a d j u s t m e n t f u e l t r i m O BD " at which adaptation does not yet introduce additional corrections of themodel. For example, if the " o f f se t a d j u s t m e n t f u e l t r im O BD " is 10 and the range of " T o l e r a n c e " is 5, thisadaptation will be activated when the correction read from OBD is less than 5 or greater than 15 and works tomaintain the correction in the range from 5 to 15.

M a x a d ap t i v e g a s t r im ( % ) - maximum correction of gas mixture.

Sa m p l in g d e l ay ( m s ) - the parameter specifies for how long the vacuum in the intake manifold is to bestable, for system to record a given sample to memory.

H o u r s a d j u s t m e n t ( h ) -Time for "learning", after this time the system goes from " D y n am i c c o r r e ct i o n " to " S t a t i c c o r r e c t i o n ".Selecting " C o n t i n u o u s " makes this function not active and the control throughout the operation will adjustthe mixture of gas according to OBD. Selecting a different value will cause the system for the specified time willcollect and refresh the corrections map and correct the mixture of gas according to it. After the preset time haselapsed, the system will continue to correct the mixture of gas by the collected map but the map will be"frozen", i.e.: no longer refreshed. This option prevents "force" correction of the mixture, despite theexcessively worn parts of gas installation. After the course of tens of thousands km it may be that the wear ofcertain elements (such as unstable pressure on reducer or uneven work of gas injectors) is so large that the

lack of OBD adaptation in such a situation will cause turning the CHECK ENGINE light on and will force the userof the car to visit the service and repair the worn parts.

T em p e r a t u r e t h r e s h o ld ( C ) - adjustment will only be active when the reducer’s temperature is above theset value.

RPM Th r e s h o l d ( R PM ) - adjustment will only be active when the engine rotations are above the set value,e.g. the chosen values e.g. 1024 cause that the system doesn’t take OBD corrections at idle into account .

L oa d Th r e sh o l d ( % ) - load threshold (vacuum, expressed in percentage) above which OBD adaptation willwork. Load threshold prevents collecting maps at very light loads, e.g.: when engine decelerating, for amoment before the cut-off in some cars we read very large values of the corrections even though the mixture

is normal. When this feature is on, such situations will not be taken into account when adjusting the mixture.

- Fo r n a t u r a l l y a s p i r a t e d e n g i n e 100% = 0.95 bar, for example, at idle when the vacuum pressure (MAP) is0.35 bar, we can assume that the load is approximately 35%.- Fo r t u r b o c h a r g e d e n g i n e 100% = 1.9 bar, for example, at idle the engine with the turbo, when vacuum

pressure (MAP) is 0.35 bar, we can assume that the load is approximately 18%.- 0 % - function is off , OBD adjustment will be active in the entire load range.

B a n k 2 - I n a c t i v e - the program takes into account only the corrections from the first Bank; A c t i v e - the ECUtakes into account the corrections of the first and second Bank and averages them.

Cl e a r e r r o r c o d e s - A c t i v e - automatic reset of OBD error codes. The panel continuously monitors whether

there are errors in the engine controller memory, and if one appears, it is immediately removed. N o t e : Insome cars it is not possible to remove the error when the engine is running, in which case it can only occurwhen you try to restart the engine when the ignition is switched on but still the engine will not start; I n a c t i v e -errors will not be erased.

The L i n e tab consists of a graph showing multiplier ratio percentage (used to calculate the gas injectiontime) to the petrol injection time. On the model tab there are petrol and gas maps. There are panels to managethe graph, maps and readings of the most important parameters of the installation.

The model curve can be corrected in several ways:

- T o in c r e a se t h e g a s m i x t u r e , t h e m o d e l cu r v e m u s t b e m o v e d u p w a r d , t o r e d u c e t h e g a sm i x t u r e , t h e m o d e l c u r v e m u s t b e m o v e d d o w n .

- To move all the points of the model down or up, click on one of the points with the l e f t m o u s e b u t t o n (the point turns green), then hold down the CTRL ke y and u s e t h e k e y b o a r d a r r o w k e y s d o w n o r u p .

- To change the position of a particular point on the model line, click on the specific point by the l e f t m o u s eb u t t o n , then using the a r r o w k e y s o n y o u r k e y b o a r d change its position v e r t i c a l l y or h o r i z o n t a l l y . (For

this purpose, you can also use the Pa n e l window, located in the upper right corner. The icon " t r a s h b i n "restores the default model settings).

- Switching between the active points can be made using the keys PGUP and PGDN .- For adjusting the settings using the k e y b o a r d , holding down the SH I FT key during the adjustment

increases the adjustment steps.- You can a d d p o i n t s o n t h e m o d e l l i n e , in order to do this, click the r i g h t m o u s e b u t t o n (model curve

Ca l i b r a t i o n i s co m p l e t e when the gas map line overlaps with the petrol map line.If after adjusting the model line maps, the lines do not overlap, you should make another adjustment in the

same way as the first time. So select the function S u g g e st e d t u n i n g (when it is active and highlighted inyellow), press the A u t o a l ig n m e n t button or carry out a manual adjustment of the model curve. Then selectthe option V ie w s am p l in g and create a new gas map. These steps are to be repeated until the gas and petrolmap lines overlap.

In the automatic option,after pressing the A u t oa l i g n m e n t , the programwill correct the modelitself.

After adjusting themodel you have tocollect the gas mapagain. To do this, selectthe option V ie ws am p l in g . Only the

Finally we suggest that you check the engine at low rpm. To do this, you leave the car idling, on p e t r o l andwatch the p e t r o l injection time. Then you change the power supply to g a s and again observe p e t r o l injectiontime. After changing the power this time should remain unchanged or should not significantly change.Permissible difference is about 3%.

In the example above, the petrol injection time at low rpm is 3.05 ms. After changing to gas supply, thetime should be within 3% error which should be from 2.95 to 3.13.If this difference is greater, it must be corrected by setting using the tab T u n in g - > M a p .

The Com p e n s a t i o n tab contains charts with which it is possible to reduce the impact of changes intemperature and pressure, or acceleration on the mixture.

Com p e n s a t i o n s for the r e d u c e r t e m p e r a t u r e a n d t h e g a s t e m p e r a t u r e help maintain optimal mixturewhen the engine is warming up or when the gas temperature rises above the standard:- immediately after the switch after a long standstill when the engine is still not warmed up and the gas has lowtemperature and high density - enabled compensation prevents too rich mixture - gas injectors opening timesare shortened, eg .. at Tred = 30 at 4%

- when the gas temperature increases, gas density decreases and it may lead to serious impoverishment of themixture, when you turn the corrections on, the high gas temperatures the ECU enriches the mixture, forexample.: At T of gas = 90 at 4%.

Com p e n s a t i o n for gas pressure prevents changes in the mixture at pressure fluctuations.W o r k i n g p r e s su r e - the pressure at which the correction = 0 By changing the c o l s , you change the range of pressures to be adjusted.

A c ce l er a t i o n c o m p e n s a t io n helps to maintain optimal mixture at a sudden increase in injection time (forexample ...: during acceleration). It graphically shows the difference between the injectors opening times inconsecutive cycles.M i x t u r e a l t e r ia t o n - allows to set the percentage of enrichment or weakening of the mixture whenaccelerating.

Re t u r n S p e e d - allows to set the time of returning to the injectors opening time value without taking intoaccount compensation during acceleration.
