I did it, but it was a clusterf*** of awkward, and I took ~1.5 year breaks from this place.
There are more affordable 28DIP to PLCC32 adapters to make a dual Ostrich setup work now. 96-98 "wrap around" "book style" JTEC is pretty easy to chip, the potted in jelly JTEC+ (and whatever the potted in hard jelly gold case WJ ECU is called) suck to deal with to the point I would not even try.
I'll cough up an un-passlocked version of my 97JTEC.xdf if anyone wants to dig through it and see how values are expressed.
As a matter of curiousity I'd be interested.
I have SCT Advantage 3 coming in the mail... With that I'll be able to write tunes for my 98 ram v10 or any dodge vehicle... Just needs my SCT Flasher to put it on the vehicle.
SCT its a 1 licence per vehicle thing?
Uh, yo.
the 2 .bins are the rom dumps i think i provided years and years ago, the other is his definition file for tuner pro. if i can find my socket jtec which i havent seen in like 10 years im going to try it out. otherwise i guess im going to build a new socketed jtec.
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?
