First, if you know anyone with a 92-93 corvette or a 1993 Camaro Z-28 could you please direct them to. I need to borrow thier ECM to determine if mine is bad or not. 2nd I would also like to borrow like to borrow someones LT1 fuel injectors. Anything above 24# and below 37#. Need this stuff to finish troubleshooting my car. She's almost there gents.... Thanks a bunch.

Just working out some issues. Car is running really rich so I'm trying to figure out what's wrong. Right now I'm trying to make sure my ECM isnt bad. I havent had the chance to do any real tuning yet because Ive been busy. I need some road time with scans so I can plug the info into VEmaster and see if it can get the VE tables were they need to be. If that doesnt work I want to see if switching PCM's help. If that doesnt work then Ill change the motor wiring harness. If all that doesnt help then Ill have to start all over again and figure out what's wrong. Man I hate Speed Density.

I'm sure u've probably done all this.. but i'll mention it just incase:

Fuel pressure and regulator is ok?

o2 sensor?

TPS?

Vacuume leaks?

ignition is strong and proper?

Compression is ok for all 8 cyls?

Fuel psi is fine
it's running super rich in open loop so that rules out the o2's at the moment
TPS is with specs
No vac leaks that I can find and the shop didnt report any
Brand new Dynaspark opti, new plugs, and wires look ok
compression is good.

I need to open the t/b blades some and see how that effects the idle. I think the cluster tach and actuall rpm's are a little off, I'm guessing 200rpm or so. If that's the case I can crack the blades open to 1100 and still be ok but it all depends on what the IAC counts are. Once the idle is good I can get to the drivabilty side. Ive been reviewing my tune and two things I noticed was the Injector flow rate is off by a little and so is my cylinder volume but not by much. Once I get a chance Ill correct them and see if the minute change in those constants make a difference. It's a speed density car so I think it will or hope it will. My BLM's seem to be stuck at 108 alot which implies it's running lean. If I dont have a exhaust leak before the O2 or a vac leak then I dont know what could be causing that. I also need to check if the car is jumping from open to closed loop properly now that the heated portion of my o2 sensors is disconected at the moment.
