Need some advice on some readings from my car.
 

readings from my riviera with a 2.4 pulley FWI. Hi-flow cat. and 2 1992 parkavenue injectors replaced under duress (spelling) (inside joke)

Mat: 288 degrees
BLM: 137
Int: 128
Adv : 13 degrees
KR :2 degrees

this is at WOT.

Looks pretty normal. On a hot day, you're going to have more KR. Be careful with that. 2.4 may have been a bit too aggressive without a better exhaust, particularly ported exhaust manifolds.

MAT of 288 degrees? ... really?

It was 100 degrees outside with the 2.4 pulley on. (hehe) I am going a little KR which I know are from leaky manifolds. Going to be taking care of that soon.



Is that good or bad?

Um, thats really high

uh-oh ummm...k Really high?! what is the norm for our cars (I hope it is just a bad sensor)

We don't have a MAT sensor. You do. I don't know what your normal readings should be. Do you have an FSM?

Hmm, I interepreted it as IAT, because my scantool says MAT instead, when I know I don't have an MAT to begin with.

No I don't have a FSM :( .


Funny my scan tool doesn't have a IAT reading? At least I don't see it?

Disconnect your IAT and see what the scanner says.

I think 288 might be the realm of the max reading for the IAT...

IAT's are messed up... nuf said.
BLM's of 137? Your running really lean. What are your 02's at WOT?

Judging by how high your BLM's are and your INTs at 128 I can tell that your PCM has learned that you need more fuel and basically is finished learning how much fuel it needs.

I think you need a bigger pulley.

Or to check the fuel pressure. That's becoming a typical problem on the 92-95 L67's with age now. It's best to replace the pump and regulator at the same time if you don't meet spec.

You need at LEAST 41 psi at idle to run a smaller pulley.
