air fuel ratio help...
hey, im curious to know what should the a/f be reading when youre at...
Idle
Boost
Crusing
my cars been falling on its face at idea and at the 3-4k range in 6th gear giving some gas spikes at 16... how hard is it to tune?
ps are you guys planning to come up NE for a tuning session?

I'm not running the Int-X (I sold it and went back to the EMU), but I was running that lean when I did have it.
Its called tuning!
The trick is to learn to look at what is actually going on, not what the programming interface is telling you.
The idle ranges on the Int-X are affected by all of the load ranges that surround it. This can be mitigated to some extent by using the Matrix mode, but it still requires that you know what the real pulse duration is at any given moment, not just what you are telling it to do.
There are so many interactions on the Int-X and each has its own granularity, which makes it almost impossible to predict the outcome. Therefor, you need an independent way to monitor pulse duration and load.
The drawback is that as soon as the weather changes, the Int-X's tune goes all to hell if you are running a nice, lean tune for mid-range and idle, which is why it is normally tuned overly rich which compensates for the lack of real temperature/baro compensation.
