low block learn numbers and slight miss

:frown: low block learn numbers and slight miss but tons of power bl is at 90 at idle. Anyone have any ideas ? I have changed the ign mod. IAC . MAS seams fine. running Reds 93 chip. Going to change coil and wires next. Will clean injectors next week if the coil and wires don't resolve the issue. I have checked for vac leaks all new rubber hoses. Please Help

Sorry thinking of my old setup with the dual pumps. It only has one pump hot wired direct

Any solution to the low BLM figures yet?

Hi,
What's so amazing about a 93 block learn, with the mods you have? I would have to say that your stock(am I correct?) ecm is trying to do all it can to maintain it's programmed function,given the chip you have.

Let's not add any more confusion than there is. If he has 50# injectors, and chips cut to run 50# injectors then the correct BLM should still be around 128 +/- 10 counts.

mthere is no miss just bad eratic idle . it runs great going down the road but at idle it can go fron 550 up to 900 rpm flucuating
does scanmaster show o2 cross counts . i am not sure what that is

and i have not checked for exhaust leak but i do not hear anythging drastic hapening

WE still need to know your MAF numbers at idle. Or did I miss it?
Check your scanmaster and look at the AF reading at idle.
Ideal should be 5-6.
