Hi everyone, I need help since I'm crashing against a wall over and over for the past two days and I have little patience...

So, I have a 4G64 2.1 Long Rod with S3 cams and FIC 2150 injectors with two walbro 540lph pumps on Speed Density OMNI 4 Bar Map... right now I have problems starting the car with speed density or maf, it's a fresh built engine and the car has not ran since 2017 when it was totally stock...

so, long story short, last time it ran stock with maf, I don't have anything stock right now and it's on speed density...

the car tried to start on 96531706 tephra map, but it didn't I've replaced so many things that right now I'm a little bit like Uncle Biden, don't know where I am or where to start, no cel codes...

OEM map was 96940011 and it is a 2005 GSR, I'm the second owner and I've lost contact with original owner since 2017...

So who can help, of course I will pay for your time if it helps me to get the car running, I'll do the fine tuning... I was used to tune running evos but I don't touch one since 2019 and I never did a tune from scratch like this one...

I would need a new XML and HEX file, since I think I messed up the ones I have

 

Do you have any stock injectors you can swap in? I would probably do that to eliminate one variable.

 

Well, It was the maperformance coil on plug wiring messed up backwards... it was a friend who told me the dumbest but smartest thing ever when he heard how it was cranking... he told me "check the wires from the distributor"...

So I put the wiring backwards and it started right away...
