Hey Steveo,

Thanks for the quick reply

The limo is shifting pretty well overall, sometimes there's an abrupt 1-2 shift (depending on rate of accelerator input), but usually it's pretty darn...

Formula wise it seems like we are coming to the same conclusion whether it’s by Tire Size or Diameter the results basically the same, despite the fraction rounding difference. I updated the .xls to...

Ohhh I hadn't thought about load as an influence, thanks for the clarification.

Oh btw, during my deep dive I came across a EE Speedo Calculator.xls from EagleMark. Now I might be getting a bit out of my league here, but I noticed that the formula for Speed Scalar - Divisor in...

I can't believe it's been six years since I started this LT1 swap thread! I just re-read the entire thing a few days ago and honestly it was like reading a foreign language, I had completely...

Haha based on a few LT1 forums, "home base" (aka "home plate") was the way people were describing the top air cleaner which looks like a home plate from a baseball diamond. I wasn't sure if it acted...

Maybe a variation for this for the PNP circuit. i've seen some threads referencing a diode, but have yet to understand the need or application.

Today was better than the last two combined. I uploaded the final tweaked bin file (EGR scalar corrected, and oil life/ level turned off) and the limo is running pretty smoothly now, and I'm not...

Haha, I'm so deep in. The only way out, is through.

Oh hell. I guess the aluminum bracket we spent the day fabbing up will have go :mad1:

Thanks for the heads up!

Well, today was bit challenging. Since I haven't figured out how to adjust the Hearse bin, I thought I would just tweak the existing file and turn on EGR and CCP, etc. After making the changes and...

Hey guys,

My buddy and I have made some really good progress on the harness the last 2-3 days. It's almost fully installed and we are finishing taping it all up. I forgot to take a pic but it...

Took the plunge and started the conversion of the '96 harness. Thanks to the help I was able identify and remove quite a few component plugs/ wires (ABS, wiper, washer, Low Dist, etc, etc). I'll pin...

Thanks Scott, very helpful.

The existing harness I have has a broken Blue PCM plug, which someone prior has epoxied shut. They managed to put the knock sensor pin in the wrong location before...

Thanks dave w, ScottP and lionelhutz for the great info and suggestions.

Agreed that a tone/ beep Ohm meter is very very handy. I've been using one to find the plugs that I have identified...

I'm still trying to identify some of these

ABS, right?

Update: I got dragged in to a major work hole the last few weeks but managed to finally spend a weekend on the limo.

Since it's been determined that my existing engine harness is to be scrapped, I...

Yeah I thought the fans would revert back to normal operation once I turned off all the offending codes in the bin, but either it doesn't work like that, or I'm missing something.

I thought I had EGR related parameters turned off in the bin, but it's possible I didn't do it correctly.

Here's also what Painless says about the PNP circuit.

Thanks for the link. I also just bought the full service manual set for a '94 RM. Up to this point I only had the '95 supplement to work from. A lot was ok, some was not.

I have the full service...

For the new harness I was going to use this as a basic guide: http://lt1swap.com, as well as use the Painless Wiring LT1 harness installation manual, attached. If you've go any other useful...

Agreed, I probably wasn't clear in my post above but I'm starting over with the harness. I think it's time better spent. There's too many weird issues to chase down with the existing one.

At least...

Thanks! As you'll read the fight isn't over just yet. But I'm closer than ever!

Thanks of the file! Hopefully I'll be able to check it out before I leave town!

I hope you guys don't mind my long rambling updates, because here's another one.

Now that I finally have some major progress on the car I was hoping it would be a little less painful to go work on...
