I just got my setup complete on a freshly built motor. She started up like a champ and runs nice. After installing the 450cc injectors and all my turbo stuff it doesnt like to run unless the fuel pressure is set below 20. I tried to program a base map running and tuning the fuel down by 54% of the duty cycle, and it still tries to shut off if i raise the fuel pressure over 25. When it should be able to run fine at 45, which is stock. Anyone have any suggestions? Anyone know of a good basemap to run on a d16z6 with 450cc injectors, with a t25 pushing 8 psi? I will be having it dyno tuned on saturday, but i was wondering if anyone could lend me advise to get her running decently so i can drive the car on friday to run to a few places.

 

Sounds like it has a base map for 240cc injectors. Make sure that base map has 450cc injectors in it.

 

yea im gonna try burning a new chip, i think the chip might be messed up, because im going into limp mode also, and when i plug the stock ecu in it doesnt throw a code or go into limp mode, and it runs smoother.

 

what program are you using??

 

When you put in the 450's did you check to see if they were peak and hold injectors? If they are you will need an injector resistor box or resistor packs. also pm me your e-mail and I will e-mail you some base maps.

 

Yea they are peak and hold, and i already wired up the resistor packs. Im also using Crome for tuning.

 

since it's a freshly built motor you should drive it around without the turbo on for a while OR since you say you are getting tuned... break it in on a dyno is the best thing to do...

 

yea im gonna be breaking it in on the dyno tonight. Hopefully all will go well.
