well, as I stated, that was done on a 318... NOT a 4.7...
I also never claimed they were perfect tests, I also said we have done this
many times, with and without driving cycles. this was 1 sample, I'd be
happy to post all of them as soon as I get all the files on this computer.
I don't see how by removing the jet chip one would have to wait for the PCM
to learn what the PCM sees... but I, as well as the majority of us on the
list, do not know exactley how these computers work.
don't kill the messenger, I'm merely posting results. Personally I could
care less if the JET works or not, I'm real, I'm MoPar :-)

I am sorry but that is incorrect. After reading about the OBD-II computer
chip, I would side with Bernd. You just cannot connect it and take a
reading. It requires mileage and maybe more for the 4.7 engine (I found out
it takes longer than 75 miles). It does not work like that. Or neither by
disconnecting the Jet Chip or any chip for that matters, then applying the
Dyno or 1/4 mile strip at that moment without the ability for OBD-II to
relearn.
So will the Mopar HO chip work right off? I cannot not see it either.
Sensing the a modified TB, free flowing exhaust, etc...

well out of the 5 times we've compared them, we've pretty much covered the
gamut on ways to connect/disconnect the thing. On that particular run, the
customer came in with the JET already connected for several days, then we
simply unhooked it. I can tell you from other runs we've done that the
whole "let the computer learn the JET chip" notion is bunk, the evidence
just doesn't support them.
These graphs also support claims from probably 90% of the people I've talked
with that own the chips, they experience a power gain only at part throttle
driving. That is further evidenced at the R/T meet in Jacksonville a couple
weekends ago when Terry H passed around his JET II, not 1 single gain was
reported with it.

How long did you allow the PCM to relearn the sensors after plugging in the
JetII??
