So here are my readings since engine was put back in & these are at 180deg temps at idle in park- O2's- 500-550, af-04, L8- 29-30, bat-13.7-14.1(fan on), int-128, bl-137, ats-94, r-825-850, tps-.42(idle), iac-08, cc-18-260, nal-00, fuel pressue at (38 with vac line on). Does anything look off to ya'll?? Thanks!

BLMS look a tad high, but not anything crazy. Check for vacuum leaks. Also, your maf appears to read a little low, but again, nothing completely abnormal.

The maf is 3" w/ translator, huge k&n with 4" elbow into maf, 3" to turbo. & what should my blm read? im not that familiar with the scanmaster & how to read it except for coolant temp & 02's & tps & rpm's, the rest might as well be greek lol

In a perfect environment and the engine running perfect, BLMS should be at 128. Now +- 10 of 128 has been said to be fine, but I have seen quite a few posts and even my vehicle myself run very close to 128 almost all the time.

What is BLMS exactly? i dont even know what thats telling me or reading.

In open loop idle the 02's are showing a little lean. IME with a open loop idle and TT or Ext chips they are in the 600-700's range at idle.
AF is low normal more near 6-7 at idle typical.
BLM shows ECM adding some fuel typically 128 +/_ 10 is ok
IAC is low for my liking, i like it more around 20 at idle and of course it will be a lil higher in gear.
Fuel psi seems high with vac present with decent vac its usually a little lower. What is it line off?

 

[buickGN3:16]

43 psi line off. How do i raise the iac to where it should be?
