Ah! You've hacked it! That makes better sense. I found owners manuals online for the SAFC and SAFC2 units and they don't list my my D16Y7 engine as compatible. But if you could hack it, that changes things. Did you instal an EGT sensor? I don't think your cars came with them (yet), did they?
No, they did not. I installed an EGT sensor and a wideband o2 sensor to monitor fuel ratio in the 2000 Metro 1.0 liter. I set it up to light cruise from 18 to 22-1 afr. at any other throttle position it is proportional. Wide open is about 12.5-1. I have never exceeded 600* C 1100* F. I was surprised that the Metro 3-cyl could run that lean. When running over 16-1 ratio I run between 400* to 500*C. Normal temp at stoich and under load (WOT) is much higher - 600* to 900*C.
None of my cars were listed as compatible either. All you need to do is find a schematic of the ECU pinouts and match them up.
