would it be difficult to add some type of lean protection for those running a wideband? i was thinking the ecu could use the wideband input for this. the lean protection would look at a voltage or a/f range and if it drops out of the range then the ecu would cut fuel or ignition. i've been having a difficult time with my cal lately in that on the dyno everything will be fine with my af at 12:1 but when i upload the same cal again the af is messed up and goes to 13 or 14. i've never had a problem with heat soak so i doubt that would be the problem. the cal is attached if you guys suspect something with it.

Your Fuel Compensations for air intake temps seem to be a little messed up. after it zeros out, it then goes up, tehn goes negative...after it zeros, it should stay zero or go negative, but not increase again.

took a look at it. its interesting i thought i never touched the fuel comp. anyway wouldnt adding more fuel when the iat goes up result in a rich condition instead of a lean one? anyway i just changed everything back to normal from the stock itr cal so i should be fine with that.
