thanks adam i got it! i have change to mid of injection, looks to works better and set it to 220 which gives the best fuel distribution and power, can runs good.

i dont

Hello, i have a turbo engine running on modelled fuel and following fuel pressure sensor signal.
I have set the error value to 3bar which is the actual pressure of fuel when engine nor running (without boost or vaccum).
My question is , if sensor fail will g4x modified error pressue value depending on boost and vacuum? or will be always 3 bar?

Hi folks,
I am tuning a engine turbo , it is a 1.4L 4 cilinders from renault 11 Turbo, with custom injection converstion to 4 injectors.
I have the car running quite nice right now, on modelled multipoint injection and fuel rate 2.
I have had to tune injection angle for each rpm and load because if i set a low value here engine misfire and run badly.
My question is why on multipoint (semisecuential) i have to tune this value, on other ecus it was not necesary, i always though injection timing only was tuneable on full secuential injection not on semi.
how can ecu know the correct angle of injection without a cam sensor?
i let here my tables and configuration, injection angle is set to end of injection.
BR.

Hello again, Im still working on this engine as there is non solvable problem with random misfiring. I might think that Ive found out possible problem with it . I have tried to sync engine with 180 deg offset to other pair of cylinder to see if there is any change, but after changing fire order there is no change in offset at all. Its same for 1-3-4-2 and 3-4-2-1 (65 deg)

hi again i still have problem with fuel distribution, some start up engine run ok other no,when wngine run b ad if i change injection angle i solved until nest start up wherei have to change again injection angle manually.
i have lowered cam sensor but still same problem
-
HI again sensor is connected to pin24 gnd output and to pin 9 trigger, could that make troubles? should i need to use only pin 7 for trigge sensors?
resistor between pin 24 and 9 is 1.28 kohms so 1280 ohms
-
car arrive running to garage with oem ecu so i will check wiring oin sensor
-
hi resistor between pin 7 and 9 jumps a little bit but it is arround 0,6 MOhms
-
both are with car running at idle, i will check resistant
-
TriggerScopeLog running fine.llgxhi with TriggerScopeLog running bad.llgxnew firmaware looks that run better, at least it fail less times but still same problem here are new trigger scopes:
-
thanks! i will try
-
thanks! anyway i cant understand why sometimes car runs ok and other no, if i start up the var and it is ok i can run it for hours going perfect, but i stop the engine and start up tagain and it loosed the phase.

Hi Adam any new? i am in a bit hurry
-
to be honest i am not sure sensor is on the botton of the engine on the back side i will try to find some info on internet
-
hi Adam the cam sensor is this one:
https://www.ebay.com/itm/382775135277
is is possible that wires are on opposite? and cam signal is not good for that?
-
mmm so how can i solve it? will be possible to run this car on no secuential mode?
I need to finish the car for owner wiring is finished and all the car except that i am in a bit hurry with it.
-
Hi adam i am afriad no is not possible to lowered, so only solution will be wait for a firmware update? thanks a lot

hi adam car is running on secuential driverinj1 and driverinj2 to injector 1 and driverinj3 and driverinj4 to 2, trigger to 80 degrees and injection timing to 0 .
Looks to works quite well, but i have and other random problem, sometimes after starting engine it is misfiring like als or cycle idle, exhaiust goes really hot, stop de car start up again and it run nice, it can be runing good for a long time but if you stop the engine and start up again sometimes it start to misfire, only way to solved it is stop engine and start it again.
its random problem, when it fail looks like loses sync (but on pclink all looks ok) i have other linkecu i will swap ecus and test becouse looks like ecu get crazy.

-
for wired injectors paired should i wire injector diver 1+2 and 3+4 together or as on a normal system 1+4 2+3?
-
triggercrank and cam scope.
right now car is starting with single point injection type and fuel rate 2
-
mmm oki problme is that i have already make wiring and i just use inj drivers 1 and 2...
-
hi Adam as you say i have sync and spark with rover mode, without cam sensor, i will fit it and make s trigger scope on the other hand i don know if it will give any advantage as it has wasted spark coil and just two injectors.
ON the other hand i am not usre which type of injection use on this car manifold is a bit weird looks like inj1 feed cil1 and 2 and inj2 feed cil 3 and 4.

thanks!
