Title: reading eeprom on omega96TD
Post by: MCU on 08 October 2019, 21:27:16
 :o I got my TL866cs programmer out. i can read my 97 2.5td Omega with box or chip 1 037 355 974  0281 355 974. It will be read and detected as st m27c256 DIP28.
then i figured it would work to do the same with the Omega96, box 2537355449 028100121, but i cant even find it, does not respond or exist. It should be the same type of chip. Anyone who knows ?i did find software in a database and i can burn the original software to a st m27c256..

 :-\ well the issue is this: https://atariage.com/forums/topic/275512-m27c256b-eproms-and-minipro-tl866-trouble/  Chinese programmer with old software and propably not working as it should. They don't sell them anymore and there is a new tl866II that has evened out the glitches.

Replied to your PM, soz about delay, been a busy week.

Those cheap Chinese USB eeprom programmers are crap. I mean really crap.  If you're playing with this stuff, get something better.

For the gearbox, there aint a great deal you can do. V9 firmware is about as good as it gets, but it cant solve the ratios that are in the gearbox that's ultimately built for petrol engines.  No amount of tweaking is going to resolve that.

For engine ECU, assuming yours isn't DDE2.0 with autobox (ie, 215 ECU), there are some good premade, tried and tested maps out there. There is a lot of junk as well, as amateur tuners simply adjust the fuel multiplier rather than map it properly.

Obviously, chipping a TD with the standard AR25 autobox will destroy the gearbox. Usually in less than 500 miles.
