The engine is almost fully broken in, so the next on the list is performance tuning.

I was toying with the idea of trying to tune with a narrow band O2 sensor & a/f meter, but after much research I found they are pretty much like an on/off switch, not giving an accurate indication of A/F conditions around lambda.

Innovate Motorsports just released a wide-band meter that can log up to 44 minutes of data from multiple inputs and can be downloaded to a PC for analysis ($350).

I just talked to the vendor and just won Car Craft magazine's product of the year and will be releasing an auxiliary input cable to capture RPM with inductive pickup within the next couple weeks ($99).

Any of you carb or CIS guys interested in a group buy? I'm looking to pick one up once the RPM pickup is released.
