    If you're still looking for the correct PCV, keep reading. Any time you change things that adjust the vacuum profile of the engine, your PCV valve will no longer work as intended. They are tuned to...

    Tuning out cam-surge?

    I have a 95, 383, TFS heads and LE cam. 224/230 .560/.544 112, 3.42 gear with Yank 3k stall. Tune was done by Moe Bailey.

    The car has pronounced cam surge when cruising at 45+. I've tried a few...

    I don't have a wideband, so it's all off of narrowband.


    I have RT and I'll try uploading one of the tunes and then putting the info up here.
    Thanks
  4. Tuning, timing and fueling - can't seem to get it right.

    I've had Moe Bailey, Solomon, PCM4Less, PCM Performance, and one other place try to tune this car. Without exception, every single one of them produces loads of ignition knock or ping between 2500...

    Fan temps and hysteresis in TunerCat

    I have a 160 tstat. Current turn on temps are 185 F and 200 F (low speed) and 200 / 205 (high speed). Speed threshold is 40 mph. Are those temps acceptable? I've seen higher suggested but wanted to...

    Thanks Steveo. I put the stock TB back on and the car straightened right up. Still have a split at idle, but it's only at +2/+11. I suspect I can get that down by tweaking fueling?

    Update: Removed the Edelbrock intake, installed the stocker. MAF readings are back where they should be, vac readings are spot on. However, the BLM at idle is still around 150-153, with both sides...
  9. Update: Installed the Edelbrock with correct...

    Update: Installed the Edelbrock with correct gaskets, which fixed the left 02 going super lean. Now they're both swinging as they should, but the car is still dumping fuel and sits at 160 blm at...

    It's the LT1 specific model - the 7107. Interestingly enough, its powdercoated red, which according to Edelbrock is only available for the LT4 - but its stamped clear as day 7107. I don't have the...

    Yes - that's what I set out to do yesterday. Have the manifold and gaskets ready to go. Once i saw the problem, though, I figured I'd give this thing one last shot. If it doesn't work, it only cost...

    Update: Huge air leak in the valley - both sides. The intake gaskets were a tick too small for the openings and as a result, it was sucking air. I have ordered the correct gaskets - which are not the...

    Thanks for the info. Yeah, I am starting to think this Edelbrock LT1 manifold may be the source of my ill's. I swapped over the OEM throttle body and it had no affect, so the 58mm one is back on...

    I want to say that you all are f-ing awesome for helping. This engine has been kind of a bear and I while I thought I knew what I was doing, its obvious that there still is a hell of a lot to learn....

    Hey Mitch - I'll check the plug leads. Plugs are new, though. If it were spark, would the 02's not read lean and instead read rich due to unburned fuel being pushed into the exhaust? The throttle...

    Hi Dave. The link to the eehack log is in the first post.

    Some free-wheeling thoughts:
    1. Intake and throttle body are new and were not on the previous install. Heads were pressure checked...

    Thanks Mitch.

    Engine is a 383, and I forgot to mention that the car was tuned by PCM Performance. I have a second PCM with a tune by Moe Bailey (also for a 383) - swapped it in and the issue...
  19. Wiring checked. Engine in. B1 02 error - lean. eeHack log attached. Paying bounty!

    I will pay a bounty to anyone that figures this out. Cammed 383, 58mm tb, trick flow heads, CIA longtubes, cats. Every sensor on the engine is new.

    Had the entire harness out checking it and...

    Update: So I think I've found at least part of the problem. I took out as much of the harness as I could and removed the loom. The bit behind the passenger head is all that's left in there because...

    @Steveo According to the FSM, the 1995 Caprice/Impala has the MAF, both 02's, AIR, EGR, and CCP valve all running off fuse #4, which is the one that blew-out, giving me some of the codes. The trans...

    I've got a Fluke 88v, so I'm good there. Thanks for your suggestions and I'll get cracking.

    The pink at the MAF is the positive lead, and is supposed to carry 12v key-on. Mine carries 12v key on,...

    For future searchers: Increase the line pressure across the board 5% for a 52mm, 10% for a 58mm. I have also seen to copy the cells up one space for 52mm and up 2 slots for a 58
