RE: 33920-50G11 1995 Geo Metro 1.0 3-cyl

This is a screen capture I took while working on the ECU. I have TunerPro running diagnostics and address hitting with the LogicPort analyser monitoring code execution. The line highlighted red is the data returned from the table being stored in RAM.

Any progress here R? I have four N. American geos all of them are 1.0s, and one 1.3 Suz swift GT.

Interested.

Thanks

The diagnostics for TP works, the mapping information is quite well advanced, many of the parameters are known but it needs some more on vehicle datalogging to prove the axis and scaling values. The files can be downloaded here:

The 50G11 has an extended diagnostics capability with something like 12 addresses that aren't used by the Tech1, I'm producing a couple of different definitions so these can be used for logging some of the unknown parameters.

This is a current reverse engineering project:

33920-50G11 PCB

This is a 68HC11 based ECU so software and hardware tools are readily available. The ECU shares the same design as the 1995 Geo Metro 1.3 ECU/, but with different software, which is good because I can use the 1.3 ECU that I have for development.

I am quite well advanced with producing a TunerPro definition and I will post that here when it is proven.
