I finished wiring up the new sprint re.
Loaded up the s4 map. No start.
Factory coils, I'm getting good spark. Fuel pump's working. The car ran well on the Microtech I had in it b4 (until the Microtech stopped working).

Any thoughts as to what to check?

 

Sprint re won't run the low impedance injectors. You have to wire in resistors or a resistor pack. Don't know if you did that or not.

 

I've got all new Injector Dynamics injectors that are high impedance.
1000's for secondaries and 720's for primaries.
I've been adjusting the overall Trim in an attempt to compensate for the larger primaries(just to get it to start and idle).
My adjustment has been from 0 to around 35% with no success.

 

Did you synch the timing? RPM displayed in software while cranking? Trigger since last home count while cranking?

Larger injectors than stock will require a negative trim, not positive.

 

Have you checked if you were getting power to your injectors ?

 

Wow. Sometimes I amaze myself. :-(

That was the problem.
