Recognize this Chip? - ZR-1 Net Registry Forums

The original owner told me his mechanic put in a "racing chip." Can anyone help me identify it (pic attached) so I can understand what the modifications may be?

Thanks,
Roger

Looks like it's for a 90 since it does not have the KS circuitry on the chip. I'll bet it may run Open Loop, and changes made are for WOT (probably some timing and fuel) but that's about it. You'd need to read the chip and compare it to stock to tell definitively.
