Low BLM's #@$WTF&%#

[94z286speed]

Could someone please shed some light on this? I have low BLM's in all cells. These are 115. Which I assume thru research is rich. I have tried lowering the Fuel pressure with no luck. What are the causes of low BLM's?

Need more info... what chip, any translator, what FP, MAF, etc... does it stay at 115? is it okay at all other RPMs except idle?

TT chip, 43psi line off pressure, no tanslator, 115 all cells, stock maf

"lazy" O2 sensor...??

What is the MAF reading at idle, warmed up in park?

AF 6 warm at idle in park

The MAF could possibly be reading too high. The scanmaster only reads the first digit "6", but it could be say 6.8, which would be too high.

Another thing to check is that the chip matches the injectors. Get the part# off the injector and I'll look up the chip to make sure (give me your chip# or name).

You already checked the chip and injectors. The injectors were bought from you, they are new style 009's. I have 2 chips from you one is number 5118. Both chips create the same results so i believe it is not the chips.

I will try to find a maf to swap

115 all cells is a major issue, Id say its the stock maf isbad , ls1 maf and translator is the way to go it will run much better.

Just a heads up to all involved. I swapped the MAF sensor and reset the PCM. Once this was done the blm's were at 125 to 129 through out the range of cells. I then put the old sensor back and the blm's went back to 115 in all cells. Another thing I noticed was the AF went from 6 with the old sensor to 4 with the new.

I guess we found the problem.

Thanks to all involved.

Which MAF did you switch to? Just curious cause I am having the same issue.... low bl's

I used a new reman i bought. I also tried a correct BW code and it gave me the same result as the reman. I have a new reman if you need one.

Glad you got it fixed. Just curious if the screwy sensor had screens in it?

Sounds like i'm gonna need one. Was trying to wait 'til this winter to upgrade to a Ls1, translator, and alky.
