Version 4 Progress Update
Added 2023-01-28 21:29:45 +0000 UTCSo I'm getting pretty far along with the next version of the OS. I haven't done any testing yet, so there are probably some bugs that I will need to go back in and fix, but at least most of the code is implemented.
Here are the new features in Version 4:
- Gen 4 MAF Calibration Table
- Over Boost Spark Cut
- Wideband Ready Test
- Wideband Scaling
- Launch Control Soft Limiter
- Engine Speed Soft Limiter
All the new code still needs bench tested, and I need to figure out how I'll be testing the MAF code as I don't have a setup to simulate it.
I'll also be putting out an update to V3 as I discovered that I actually implemented the Wideband Ready Test in the code, but forgot to add it to the XDF, so if anyone is using the Wideband closed loop fueling that may help keep it in closed loop more often.
Thanks everyone!

Auto transmissions are my weak point. I guess it's good I don't need it yet. I just know that I probably won't be able to hold the car in the lights once the turbos spool up. Even with the C6 brakes and the 255/40ZR-18's on the front. Maybe the launch control feature will help with that. I'm definitely excited to try this out.

2023-03-08 03:02:42 +0000 UTCThanks for the support! I wish there was a way to add atrans brake but sadly that’s not possible without mechanical modifications to the transmission itself. The whole valve body needs to be replaced to modify the fluid path that allows locking the transmission in both gears.

2023-03-08 02:18:24 +0000 UTCHello! I just joined and wanted to let you know how impressed I was. I have a 78 El Camino with a 5.3l and a 4L60e. I have been using TunerPro and PCM Hammer to get it running. Already using the P59 with the 7603 OS. I'm adding twin GT3582 turbos and really don't have the spare income to spend on a HP Tuner. So I'm quite excited to find this project. Two features I'm curious about would be is it possible to code in a trans brake (locking the trans in first and reverse) and if so how about a bump in feature? Just thinking it might be a possibility with a electronically controlled trans.

2023-01-29 16:19:05 +0000 UTCWell, I stayed up entirely too late last night playing with EASy68k because I knew it had a simulator that could step through code line by line. It took some time to get it working, but I was able to put some code in there and get it working. I was able to fix some bugs I had in the soft limiter code I wrote and I'll move on to testing some of the other code before I do bench testing. Thanks for the push/reminder about stepping through code!

2023-01-29 15:55:46 +0000 UTCI don’t have a way to step through the code right now. I have a USB BDM NT but I haven’t figured out how to step through code with it. Supposedly it has the ability to do it.

2023-01-28 21:59:52 +0000 UTCPretty sweet man! What are you using to step through the code? I'm going to start looking into pcm hammer to see what can be done for it to include the new code into a cal only flash.
