I've spent the last couple years rebuilding this Sport - replacing all the electronics, sensors, mechanical, new rear ProRock axle, complete tear down of the front and new CM shafts, brake redesign, etc. With 600K on it everything was finally starting to show the wear and tear it gets. But, with the exception of a couple misc things, that looks like its done.

The last engine swap specific thing on my list that we didn't do was changing out the 3.5L injectors for the 3.0L injectors. That was completed today. It was somewhat of a surprise that it started and runs. I only had Internet rumor and some 3G/Eclipse reports to go on, so .... laugh

LT fuel trims with the 3.5L injectors were running in the -2.4 to -4 range all the time and STFTs were all over the board slamming +/- as far as they'd go constantly. Metering was obviously horked because of the mismatch between the programed data in the ECM explaining the 3.0L injectors it THOUGHT were installed and the physical reality of the higher flow 3.5L injectors that were ACTUALLY installed.

As documented earlier, this isn't news. I knew what was going on and could even 'fix' the issue with the AEM FIC - except the #2 injector CEL/OBD problem made this unworkable in an emission test state.

Like I said, the good news is it runs. laugh LTFT low is -0.8 and mid is -1.6 now. STFTs calmed WAY WAY down and are not constantly slamming from one extreme to the other. Except that they are in the negative, FTs now look the same as my stock '97 3.0L and my '03 3.5L. FSMs and the techs say that +/- up to 2.5/2.75 is acceptable. Obviously the closer to zero the better. smile

The ECM hasn't exhibited any of its random wigging out behavior, either. So far. smile Everything is nice and stable and steady.

And the slightly rich fuel smell from the exhaust I've had since the day we did the swap has disappeared.

To this point I haven't noticed any change in driveability bad or good other than its glass smooth and purrs like a brand new engine. laugh
