Ok here are the details. 96 LT1 with 1 3/4 SLPs, Moroso CAI, OBDII to OBDI, deleted egr and air pump. My blms are 108 at idle and about 111 at cruise. It runs a little rich at wot; anywhere from 13.3 to 12.2.

I have checked fuel psi, fuel in the vacuum line to the fpr, new wires and new opti and plugs. One new o2 sensor. Removed Maf screen. Checked for leaking injectors. What are some other things to check for because something is wrong. Right? Would the deleted egr cause it to run rich?

If this is just a pcm thing and nothing is wrong with the motor, what is the best way to fix it? I have seen suggestions about MAF tables and injector sizes. Is there a correct way to do it?

I have also run Vemaster 4 times with no change.

Help please.

 

if your blm's are close to each other at all loads and cells increase the injector size about half a pound.e-mail me your bin and last scan and i will look at it and make a sugestion to you.all the problems come from the ported mass air.but it can be fixed.mail to c5forme2@***.net i will be up till like 2 i will do it now and you can try it.

Hey Chris. I got off the net as soon as I posted so I didn't catch yours. I put the stock ends(MAF) back on before I tried VeMaster so that shouldn't be a problem. I will send you the bin and log right now. Thanks, Mike.

 

email me, i got a program i use the locks the blms a 128

 

You have mail.

If anybody would like to explain how the locker works, I would appreciate it. It seems to me that the car would run even worse with a blm locker. If it is running rich and the blms stay at 128, the pcm won't pull any fuel causing it to run even richer with the locker. Is that right?

 

If your 108 then your rich and the pcm is pulling fuel. A ported MAF normally causes high blm's it leans the engine out. You need to find why your so rich, fuel pressure? injector constant? The blm locker is a bandaid for cars with high blm counts.

 

Yeah, I am running very rich. I put the ported ends on a month or so ago to bring them up a bit and it worked but I put the stock ones on a week ago when I got the vemaster program hoping I could get the blms right. I don't want to fool the pcm to get it right. I checked fuel psi and it is a little higher than the target but still within the limits according to the gm manual.
