Need base tune

Post by s13_silvia_redtop »

Hi i have been having some trouble getting my car to idle correctly since ive rebuilt the motor. it does drive but when i first start the car it wont idle on its on until its warm and, the fuel map is much rich under high load, i beleive my mar is too close to the turbo so im going to change that but it would be nice if i could start out with a nice tune after that to get the ball rolling, heres a list of most major mods

740cc deatchwerks injectors
Z32 maf
T61 turbo
greddy intake
im using 580 for my injector latency?
the engine is 40 over
BC 264 cams springs and retainers
and i have slightly lower compression due to the new headgasket.

thanks so much in advance for any help you guys provide i really need to get this project driving good aggain

Try this one. You will need to change the injectors from 550's to 740's.

I hope it helps,
Josh

Sounds like it's probably a tad lean at idle. Try increasing your latency a bit. Probably sort it out if this is the problem.
