OK, This may not be qa prom problem, but my BLM values are:

Cell 0 BLM 150
1 144
2 138
3 150
v v
15 151

These values change slightly, the INT is sitting around 128 (varies as expected), I still have 19# injectors in the 350 motor, is this a lean out caused by small injectors, or is it a prom problem.
The prom is correct for an 88 350. BTW, the BPW for the injectors sits pretty close to 5 under fairly spirited accelaration TPS ~ 75%.

Cheers

Richard.


88 GTA, 350 L98, used to be 305, 88 350 PROM,
19# injectors, Ported Plenum, throotle body bypass, A.I.R delete, Dynomax 3" catback, Hi Flo Cat.

 

The 350 PROM you are using is calibrated for 23 lb injectors. Since you are using 19 lb injectors the computer will "add fuel" because it is not injecting as much as it thinks it is. Change the injector constant to 23 lb and you numbers will be closer. You can tune from there.

Thanks John, I will give it a go/.

I thought you'd want to set the constant to 19lb since that is the size of injector your using. Setting it higher would lean the car out more than it already is. That would be bad..

You are correct the constant is currently 23 and should be 19. Sorry about the mix up.

Ok, Thanks guys, I will give it a try.
