Working on a 1993 ZR-1 and discovered it has an ADS Super Chip tune in it. Always wondered what this tune really was, so downloaded it in TunerPro RT and took a look. Only change was to add some timing advance at 85 KPA to 100 KPA.. No other mods.. On top of that, there is a significant mismatch between Table 1 and Table 2 at 4,000 rpm on both the Port Throttle Open spark table and the Port Throttle Closed spark table. Pretty lame...
I'll attach the .BIN in next post if anyone is interested..
