thanks!

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? BR

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: mini problems.pclx

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
