Great that you are making progress with P04! Wish I had more time to help... Anyway, here is an xdf I made some time ago when I had to reprogram a P04 PCM, I did it by desoldering the flash at that time... It's for 2002 F-body 3.8 OS 9387333. No checksum calculation included as it would need custom ...

The idea is absolutely awesome ... I did something similar to this for annotating disassembles. (IDA idc creation) New parameters were inserted/removed in the middle so the offsets do not remain the same. Whats the sequence to enable the Load XDF button ... -Enjoy Gampy, do you have something to ou...

Try going here https://github.com/dzidaV8/XdfMover and click on releases and download the exe there.. looks like he changed it according to the time stamp, that version is smaller but it runs.. Yeah the link didn't work, fixed that. IDK, I'm new to writing PC software, maybe there are some compatib...

Hi! I made a small program to help editing XDF files, especially for OBD2 applications. Many OSes have the same parameters but located at different addresses, usually whole sections moved an offset as variables were added in development. This tool allows to offset addresses of all the xdf entries th...

Hi guys, I was watching the project at the beginning, but then I got into some stuff that took most of my free time away... Anyway, I'd really like to join the party late and help you with this project! For now, I can contribute with an XDF file for 12587603 2004 vette OS. It should also work with 1...

Seems that probably ADC in the ECM went bad... Swapped for another ECM and the problem is gone. Strange failure anyway.

Hello! I'm having trouble figuring out what's happening with 165 ECM. It's in a 383 Camaro, converted to $12P code. It was running OK, but suddenly started pinging and going lean. Log shows that TPS voltage goes from 0.6V at closed throttle to 1.3V at 100% throttle. Measured TPS voltage at ECM pin C...

Hello, I've made some research into modes $3B and $3C - Write/Read Data Block Maybe some of you know what are the unknown (???) blocks for? Here's what I've found so far: LS1 Memory blocks (3C and 3B commands): 00 - N/A 01 - VIN 1 (ASCII) 02 - VIN 2 (ASCII) 03 - VIN 3 (ASCII) 04 - HDW No. (UINT32) 0...

Version 4 of my 12212156 XDF. Added new parameters: - Cranking VE Baro Multiplier and Calibration Temperature, - Commanded Fuel For Extended Cranking, - MAF Airmass Filter, - Dynamic Airflow parameters, - VE Correction parameters, - Priming Pulses parameters, - PE enable parameters, - LTFT deadband,...

Hello, I'm trying to gather information about all the 12200411 PCM pins and functions available. Here is a spreadsheet I created looking at wiring diagrams for some 2000-2002 LSx based cars and trucks. Does anyone have information to fill in the remaining blanks? I'd especially like to know if there...
