No. Just a Jumptronix. It's old-skewl. It's basically a digital voltmeter, and I have it tapped into the o2 wire at the ECU. The main thing I use it for is to make sure the voltage cycles at idle and part throttle. It doesn't give me much info despite all the numbers except at WOT. At WOT, it needs to say .92-.94, but it usually reads 1.06 (rich). The ECU reads 0-1v from the o2 sensor. If I'm lean, it doesn't cycle, and I could detonate (which I'd hear/feel), and if I'm rich, it reads over 1.00v, and I can gag the fire out making it stumble... so as long as neither of those are happening, and it's cycling, I feel okay with it.

It's that point that I use EGTs, but that's sort of pointless without logging because timing has more to do with EGT's than fuel does. I need to get a datalogger.
