Replaced Supra ecu. Now emits dense white smoke?Mass Airflow? ECU reprogram req?

[A.BuckShort]

Thanks, I’m holding the fuel controller thought for when our mechanic returns to town in two weeks (99% certain it wasn’t this issue that cause the guy to flee.) In the meantime, understanding when changing out an ecu, the new one has to be programmed to the calibrations of the vehicle where it’s being installed. Since the two I have were from salvage, neither one was. Found a number of local ecu programmers who informed that the ecus I have couldn’t be reprogrammed because either they, the car, or both are too old.

There are a lot of places that provide rebuilt units that are programmed for your vehicle with the information you supply There’s guy on the west coast who says he can do that for ours. But if both unprogrammable ecus I have are the right year for the 93 Supra, I don’t really see how any he’d have out there, that would have to be the same year, would be programmable either. Now at least I know the white smoke doesn’t mean somebody picked a new Pope.

The good news is I’ve now got a completely separate insurrection of kitchen appliances that have just jumped in to fill the void during the vehicular hiatus.

Nice - ROFL!

Just a random thought - possibly irrelevant: You should be able to pick up an AEM gen-1 or gen-2 plug-and-play for the Mkiv Supra Turbo for a reasonable price (especially gen-1)...and there are hundreds of available-for-download AEM maps for the 2jz. Of course, the most important considerations when choosing map is turbo vs. n/a, and your injector size; next would be your choice of aftermarket turbo, and the last would be cams and/or head porting. Compression (pistons) of course would be important too, but most applications (and therefore most AEM maps) suit the oem-ish range for compression (pistons).

Please keep us informed of your progress.

Just curious - any update? Still hoping it isn't the 'magic smoke' that makes it go, up until it gets released (then of course, there's no way to reverse the process, which is what makes that smoke so magical)...
