89 has MPI correct?

On my conquest, and every starquest i looked at before buying mine, there was a common thread..a nonfunctional power antenna. I went to the dealer, and they said it was discontinued and the list on it was $290 (only went to chrysler dealer, didnt try mitsu dealer). Are there any aftermarket antennas that work, as the application guide at the local auto parts store lists seemingly every chrysler and mitsubishi except for the starquest.

When changing to a new ECU, what if any functions on the car will you loose. AC, Cruse control????   Steve Gee 88 ESIR

Is anyone here running a Haltech in their car?? I have an E6A and I wanted to get some installation/setup tips and ideas.   How are they to tune??? Is anyone willing to share their timing/fuel maps with me??   Any help would be GREATLY appreciated, the instruction manual is over 1" thick     Thanks  ;D   Cullen
