I am back from Germany. And I got my ECU back from the UK after upgrade. Also installed the new Hall-effect TPS. Good news I can start the engine and it idles. Bad news the car does not drive at all. Maps are screwed up and the Baro sensor needs configuration. Maybe I need to calibrate the crank position sensor, too.
Anyway, it is anyway a moot point. Got to help my son move to Santa Barbara for his new job. Yes, another police job....
Yes I can and I did. But in my infinite wisdom I had the old TPS de-linearized with a parallel resistor to get better resolution at low throttle. I can not do that with the solid state TPS and thus the mid-range map positions are all shifted.
The theoretical good news is the upgraded ECU has a self-mapping/learning feature based on the wideband sensor input. I hope that really works.

The Emerald has an autocal feature. Once that is activated you apply full throttle (motor not running) and release. The ECU then spans the maps over the measured throttle range. Right now it shows 0.46V - 4.37V for the full opening range with 1000rpm idle sitting at approx 0.51V. The whole range can of course be moved a little by mechanically turning the sensor and I tried to get somewhat equal margins to 0V and 5V.

Thanks Randall, that might help for comparison. Maybe I can just copy the injection segment into the map file, adjust the microsecond/bit value and try if that give me a better initial map. email is my forum name AT earthlink.net.
