Thanks, Steveo. It just has the flywheel/flexplate on it. I don't know why it thinks it's in gear unless it's because the bin says it is an automatic but one isn't plugged in. Could be a harness...

94 LT1 on run stand with Long Tube Open Headers. No emissions are on the engine and have been tuned out. Basically a naked engine with an alternator. The engine idles and revs up well but I...

Well, I see that things don't stay cheap on Ebay forever. For example the ECU's like the 16188056 that used to cost $75 every day are now $150 to $200. MAFs are expensive too. I suppose it depends...

I'm glad you found your parts. It would have been hard for me not to take the whole engine. Maybe could have gotten the throttle body too?? and he MAF sensor??

Here is how I did a quick low mount alternator. There are a few low mount brackets available but I came up with this because my alternator mounting ear is in the wrong spot for the one I liked. ...

With the cylinder balance test on EEhack is it more important the numbers are high or that they are all close to each other? Mine are not as high as some I see reported here but are all close.

Thank you. That explains it. The engine is on a run stand with no transmission attached to it and no CCP or much else on it. I'm going to have to get the engine in some sort of car one day. I'll...

Am I supposed to be seeing something in cells besides just 16, 17 and 18 in closed loop performance? Don't see anything in the VE MAF analysis. I think I have to start over with the whole trim and...

here is help for harness work

http://lt1swap.com/95impalalt1.htm

Is for Impala, etc. but uses the same ecm.

This isn't going to help much but I feel your pain. I had a problem evade me for 5 months. It turned out to be a relay in a circuit I never considered could be a problem. Caused the ecm to get a...

I'm sure your right. Like in so many things, garbage in garbage out. The combination of old engine, cheap parts and old parts probably make tuning and trouble shooting difficult to impossible. ...

Thank you for looking at the data. It is a 5.7. I thought I plugged all the vacuum ports that aren't used but will check for leaks. I didn't want to spend $300 on a MAF sensor because I didn't...

Change the saved files extension to XDF and TP will read it.

Thank you. Here is the EE datafile zipped up. I think I don't understand what the Knock count number means. I thought it counted how many times the knock sensor found a knock.

I've had this engine on a stand for 2 years and never done anything with it while on other projects. I was going to rebuild it but thought I would see if it would run. After buying some parts,...

What is a good bench power supply for up and down loading bins? I've made a bench setup and used a battery before but a power supply would be easier. Thanks

Steve, I read your paper. It has three solutions. I removed the CCP Electrical Failure (unchecked the box). I don't know how much to move the min. BLM Trim up to compensate for the extra fuel that...

As always, Thanks Steve.

1994 LT1 out of a Cadillac Fleetwood. 1994 Firebird PCM with 16210011 Calibration ID. On an engine run stand with standalone harness.

I've removed all the emission items. How to I delete the...

I just spent 6 months finding a problem very similar to yours. I don't know if your car has the MAF Burn Off Relay and the MAF Burn OFF control Relay but my 88 Corvette does. I had a bad MAF Burn...

Things went swell with the EEHACK re-flash of my 94 PCM, Steve. Beer money has been sent! Bob

Thank you Steve. I'm going to use your program with a desktop. I have an old XP SP3 Laptop I was hoping would run your program but it won't install. Says it's not a 32 bit installer. I read in an...

I have a 16188051 PCM pinned up on a test bench setup. My first attempt to make a standalone system for a 94 LT1 engine I have. Is it ok to apply power to the PCM all at one time? That is there...

Hello everyone. My name is Bob and I live in Van Buren, ARK. I’m retired now after 42 years in the welding supply and equipment business. My son has a shop for me to play in and we are working on...
