mekkis this is awesome. If only i could find my socketed jtec. i havent seen it in 7 years. All we need now are some cool flags and maby some real time emulation.
mekkis, have you got any notes if your process, or the disassembly, or anything about how you located these addresses or anything?
Anyone ever put a 411 ecm in a 98 ZJ with the jtec pcm? I'm tired of no tuning solutions, I have a bdm... I have successfully talked to 411 ecms thru bdm now. I don't see why I cant communicate with the jtec the same way. Mekkis, do you offer tuning for these cars? If I can pull the bin, do we have a completed xdf with timing tables? If I can pull a bin, I can write it too.
Hi, guys!
I live in Russia and build 4.6 stroker ('99 Jeep Grand Cherokee WJ).
I need to tune my JTEC PCM.
It has ab28f200 chip so I've unsoldered it and read the programm.
But PCM has film-like board and while tuning I'll need to soldered the chip several times. That will destroy the film.
There are some pads near the chip so how can I use them to reprogramm the chip?
