I have a 383 10/1 comp 30lbs inj ,custom ground 225in 234ex 510lift in 530 exh 115 lobe 89 model maf .
In closed loop in park idling blm cell#is 5 seems to be running rich at 2500rpm in 3rd blm cell is 12 and tps is at 1 volt . tps senser is not very accurate rounding off to nearest volt .
need advice thanks.:hail:

 

OK, you have some fuel cells, how about the BLM value in those fuel cells????

At idle, I think that you should be in fuel cell #1.

But, again, what are the BLM values? You have 16 of them critters.

 

doc thanks for the reply . let me give you the low down i have jus spent several tousand dollars withe best mwchanic in my state making sure there was no mechanical or electrical problem with my engine. my problem is my engine runs rich at idle but under normal cruise at night i open my hood and have extreme temps and the headers are glowing orange. my scanner does not register blm# only blm cell # any help would be greatly appreciated.:hail:

 

GTAB,
I've been using WinALDL and it displays the BLM cell you're currently in, but without any values. You get the BLM values from your data log. What sort of scanner are you using?

at idle 900rpm tps is .54 volt blm is 108 in cell #5
at 2500rpm tpsis .74 volt blm is 1o8 in cell 11. hope this thanks everyone

you're running quite too rich.

30lb injectors seem like too much for the combo. I'm thinking maybe 26lb would be better. have you modifid the PROM to tell it you have 30lb injectors?

if you have an AFPR, and you've upped the fuel pressure higher htan stock, lower it back to stock.

gotta get some fuel out of there
