MAFT Gen 2 - Anyone? - Page 21 - 3000GT/Stealth International Message Center

There must have been a connectivity issue that was getting worse over time. About 2 days after you told me to try disconnecting it, my car just about died on the road.. no power, would just gurgle when pressing the gas. Pulled the connector in and out a few times.. VOILA! Solved the crappy running problem, and it doesn't stutter or anything when I touch the GenII..

STICKY this for a quick fix if it gets problematic!

How come the gen II uses the crank angle sensor pin 69 and not the 101 ignition/rpm for the 3s?

The PRO can control timing,so probably just a carry over from that wiring I'd guess....

Ahh that makes sense. I guess it shouldn't matter as long as that is what the gen II is setup for. It's just that whenever I think engine speed I normally think rpm on the tach.

The one question I have is that I will be logging on the palm, gen II, and my lm1. My palm/lm1 I can get rpm/tps and I want the gen II to match so I can combine logs easily. Has anyone compared RPM in the gen II to the tach/rpm on a logger?

Yeah....the wiring question crossed my mind too when I installed it.
I cant log both, but looking at the two at the same time they appear right on...
I'll look today if I drive it...
EDit: appears identcal to MMCD logger...

When logging while using AFR tracking will I be able to see what correction the gen II is doing to my tune to try to hit the target afr?

Thanks

yes...

you were correcting,that is, is it a 1 for 1 % Vs. "user tune"?
Also is above 100% leaning, or visa versa?
Thanks

to follow up on this, how/where would you see those correction results? Im not logging right now, but would those results be on the GenII as stated above or show as a value on the logger itself (and what value might that be)?

On the Gen 2 unit itself under "Sensor Mode"
