So i just finished installing my pte1200s and walbro 450 pump into the car. The car is still running stock Maf and stock ecu , it ran no problems with my stock injectors and even after i installed pump it ran no problems. Im familiar with ecu flash and i do not plan on tuning my own car but i would like to be able to drive the car to the tuner with the injectors installed already. What else do i have to do in ecu flash in order for the car to run and drive good enough to get to tuner? I already set up the scaling and latency to this : Pte 1200s

Scaling 886

3.192
2.208
1.512
1.056
0.696
0.504
0.288


I flashed the ecu with this and disconnected the battery afterwards like i read about. Car still wont fire up. What else do i have to do?

 

Any help would be appreciated

 

Too rich. I bet if you were to look at your trims after you put the pump in you would see it correcting lean. Then you throw big squirters in to amplify the problem.

Try a bigger scaling, something like 1044. Also probably going to have to tweak the startup IPW as well, as the injectors are over double stock size.

 

Is it possible for you to explain this or an ecuflash newb? Like i know the program just where do i make changes

 

pulled from another thread. try:

1044
3.312
2.184
2.088
1.296
0.792
0.72
0.48

or

860
3.312
2.208
1.512
1.080
0.744
0.504
0.288

 

Thanks ill try those now. Anything else i have to change?

 

Suggestions above should be it. Did you run stock wiring on the fuel pump, or the re-wire kit? You may be pushing too much fuel pressure without a regulator. If you're on stock wiring though I'd say you're probably fine.

Did you just mod that one section in your old tune? ...Or did you start with a new tune? If you're working with a new tune, maybe you forgot your immobilizer code/settings.

 

im modding my old tune and the immobilizer is in there... if i keep cranking the car it start to pop and fire and almost run.

something else besides the injector scaling and latency need to be touched??? like what should i do in my low octane fuel map??? anything else you can think of that needs touching so car will fire up and run

 

Startup IPW
