Re: P59 12579405 OS XDF inside - INTEL PCM ONLY!!!
That is the thing, I did change the vin. That is why I was a bit confused. I wanted to double check the one I just did and it's a service# 12586242 and hdw# of 12583660. Opened it up as well and it was an AMD chip (AM29F800BB). I guess when other have issues when does it arise? meaning lets say does...

Re: P59 12579405 OS XDF inside - INTEL PCM ONLY!!!
Not to bring up a dead thread but this OS I have flashed to AMD PCMs and worked just fine. My father-in-laws El Camino has this OS on it and it's an AMD pcm and drives perfect. So what's the issue with it? Currently reading a 405 OS that is on an AMD chip. Reading just fine. Anyone want to pipe in w...

Re: LS1 Boost OS - Development
Sorry! I just skimmed a bit and should have dug deeper tonight before asking. Most seem to only care about boost/speed, boost/rpm, and boost/gear. To me boost/gear would be the easiest as you can just go based on what the PCM is commanding and adjust DC on the mac valve. Obviously delay the signal a...

Re: LS1 Boost OS - Development
Awesome stuff indeed!!! So in theory, you should be able to rate PWM from 15 hz to whatever using that output and base it on KPA at the moment. Is that correct and does that make sense on how I'm saying it? That way it would pulse at a given range (I have one of those 3 port MACs on my test bench as...

Re: LS1 Boost OS V1.0
Love it!!!! I will start playing around with it today! Already flashing a base onto a test P59. This will be something PERFECT for my TT 5.3 C4 vette with my wideband/boost controller PCM project I'm also working on (Hardware/Arduino based). NICE WORK!!

Re: reflashed os and pcm altinators
The Generator Field Duty Cycle signal is technically not needed. It's just a check the PCM can do on the alt. All you need is to have the single wire "turn on/off" signal. I assume this is the same for your setup. I have used both in the past and also just the single wire. Works either way...

Re: Free bricked PCMs? I'll send, no charge!
sorry, forgot to chime back. Antus, I believe I have tried this. Maybe I did not do it correctly. But I tried to ground out the pin directly. I can try it again. Or unless there is other info out there? The p59 is a weird one, which I have run into on own 06 silverado a few years ago and just assume...

Re: Free bricked PCMs? I'll send, no charge!
OK, so I went out to dig in the boxes. I should have looked better. I have 1 bricked 896, 1 bricked 411, 1 bricked 463 (p59), and then I believe one from a 3800 firebird. I could have swore I had more. Might yet, just didn't go through all the boxes. Let me know. I can ship all them out to someone i...

Re: Free bricked PCMs? I'll send, no charge!
Sounds good! I'm in MN so I can ship anywhere in the states. Let me go dig through the box later this evening and let you know what I got. Thanks guys!!!

Free bricked PCMs? I'll send, no charge!
I was cleaning out my garage since we moved last year and found a large box with about 4-5 PCM's (896/411) that i am sure are all bricked. I was playing around last year and screwed a bunch up with bad XDF files (changing items I should not have). Was curious if anyone here is interested to try and ...
