I just purchased an ECU (49$) bosch # 0 280 001 132. I think it's for 2.5L Milano. BUT, I need an ECU for a 3.0 (Bosch #0 280 001 134).
Since I can't find one.......

1. Are the chips reprogrammable?
2. Replaceable with preprogrammed chip?
3. Anyone know where to get one?

I want to stick with this ECU rather than buy another one, or stand alone. Also, I don't want to change the injectors or fuel pressure.

I looked through our site and could not find anything on this. Also, is "oldbottles" off the air? Can't find Greg Gordon's site anymore!

the 2.5 hasn't any chip inside...you can't reprogramm anything...

Thanks for the info.

By 'chips' I mean 'resistors'

There has to be a way to increase injector time. Change a resistor..? Anyone know?

Apparently, R306 allows off idle enrichment max. Smaller value=more enrichment. I just need to find proportionate values chart...... Anyone have Bosch tech schematics??? Maybe, fake out with a subtle change of R621 temp enrichment resistor? Or injector time resistor change???
Any help appreciated.....

I think bigger injectors is easier after all..

Bigger injectors for big changes, resistor changes for fine tuning. At least that's how I do it. I am writting an article on the resistor mods right now. I hope to have it up in the next two weeks.

My car has no significant mods. I want to use stock set-up for the 3.0L, and just modify the 2.5 ECU to run a 3.0 with to create the appropriate high rpm air/fuel ratio. Sounds like your article will be helpful.

I gues I could always just look at the resistor bands on a 3.0 ECU and compare them to mine.........
