No, I've got a '97, 318, auto. I got tired of waiting for MP to come
out with one for the '97. Performance is there but gauges don't function.

Thanks for the info. I had no idea how things worked in this area.

I'll be putting in the MPI soon (should be a good match-up with the current
Magnum R/T cam and F&B tb) and will continue testing with this custom
computer.
When you get everything together and, if the computer doesn't pan out for
my app.,
you can try it out on your truck if you like. It's calibrated to run a 10lb
boost or a 150hp shot without detonation & idle is set at about 1000 rpm to
run undersized pulleys.

Hmmm. The computer has also had all delays removed but I don't know what
is involved with this. The throttle response is certainly instanteous at
partial
throttle and steady acceleration.

I reset the computer and, normally by the fifth run, I get my best times.
I've read a Chrysler techie recommended opening it up once at day (up to
80 mph). I'm still experimenting with the TV cable. Finished up the year,
with it 3 notches towards the firewall. It gave me a high enough 1-2
shift to stay in the power band but just not quite enough for an auto. 2-3
shift
to stay in the power band. Someone on the diy-efi list said that I should
be adjusting towards the rad to ease the line pressure. BTW, I don't believe
that I mentioned that the shift problems only cropped up after a Transgo kit
install (by a tranny pro).

I've seen his name mentioned before but did not know who he was or where
I could contact him.
Thanks for all this food-for-thought data,
Bob
