Thanks again!

w/the EIO upgrade and the 1.6 software you'll be able to log WB O2 data along w/the rest of your scan
I'm fond of the LM-1 device... they're releasing an LC-1 but release is slated for end of march at the earliest it seems
I know lots of others that run the dynojet setup and they love it as well... between the LM-1 or Dynojet really can't go wrong... they use the cheap Bosch LSU4 sensors that can be had for under 40 bux if you need a replacement (some wideband controllers use much more expensive sensors)

Correct... the EIO allows for external sensor input and output, the wideband O2 is a seperate sensor (requires sensor and a control box)

BTW, I mainly got this tool to find out what my a/f is at idle. Have you found the LM-1 helpful for that? I'm 99.9% sure (it's that .1% that kills ya sometimes)

the LM-1 is more useful for wot tuning where stock sensors aren't accurate, but can aid in part throttle also... at part throttle/idle the PCM relies on the stock Narrowband O2s which are highly accurate at 14.7:1 but then get less and less accurate the further away you go... the wideband will allow you to see accurately how far it's swinging ... but this can also be had w/stock O2s and ltrim logging ...

Mike, thanks, since I installed my cam, the car idles okay, but sometimes when I drive slowly, like at a gas station, the car will sort of surge and jerk. My LTFTs are excellent, but I never assumed that that applied to idle for some reason. I did the NoGo 60, 70, 90 VE adjustment and that helped a lot, but I want to find out what exactly my a/f is during the times she bucks and surges. If I get this minor thing solved, and a check of WOT a/f (for piece-of-mind), I'll finally have my car where I envisioned it five years ago.
