Need a tuner for a mild '93 corvette

[Fast355]

Not sure if the 93 Corvette is the same as the 93 Z28, but my son's 93 had single wire O2's.

Probably so, did not realize GM kept the sensors unheated that long. The TBI/CPI trucks switched in 91-93ish depending on application. Then again my brother has a 99ish Sunfire with the 2.2 and it has a single wire 02.

Generally speaking the single wire should be ok in a shorty header, but it could never hurt to have a heated sensor with the cooler exhaust temps from all the additional surface are and thinner metal.

I noticed that the Vette does not appear to use the a/c temperature input. The OP might add a wire from his 0-5 volt output on his wideband and input it into the A/C Evaporator temperature pin used of the F-body version of the PCM. Then post up the transfer function included with the wideband instructions to convert voltage to AFR. It would give the datalog wideband air/fuel mixture capability.
