ARG! Ok. Its NOT the F/IC. I picked up a second for the other '97 build, loaded and installed it and I'm still getting the P0203. I checked the two solder connections on the Boomslang and redid those just to make absolutely sure I didn't hork up a solder joint. That had no affect so it looks like I probably have a problem in the main harness from the ECM to the injector harness. Dealership checked the injector harness and replaced injector three so I KNOW those aren't causing issues. The last thing to double check is the ECM. I'll swap my spare back in - not that I expect this to make a difference, but I want to be sure before I have the techs double check the main harness. Sigh. Always something .... <img src="/forums/images/graemlins/frown.gif" alt="" />

On a more positive note ... after blowing a tank of gas testing and tuning this weekend, I think I'm moving forward. I think I've got most of the hic-cups worked out - at least below 3K. Working on the in town 4K plus range now.

I THINK this will work with a single map for on and off road. I took it up Sunday and did some 2-3 mile runs at 12 to 20ish degrees in 4LO and 1st, 2nd and 3rd gear - so low load, high RPM and high vacuum. I'm going to keep working on it, but I've managed to drop the ECTs from about 220 to a max of 213. So, progress of a sort .... <img src="/forums/images/graemlins/smile.gif" alt="" />
