It's not easy to do a project like this with an audience so go easy on me ok guys?  |
So far preliminary testing shows that everything on the car is good mechanically so for that I would like to thank Monkeywrench. Matt is right that when I brought the car to him originally, it barely made more power than stock. I have had real problems with the tuning from the start. The first attempt with a reflash ECU and still using the Greedy emanage piggyback just did not work as well as expected. It wasn't horrible but just didn't pull right in the upper rpm (most likely due to cam timing) but made very good torque.
It appears that the ECU problems with not starting etc were most likely due to the "ECU GOOP" that Charlie talked about from when the ECU was reflashed. Matt has been putting in a lot of time and effort trying to figure the tuning part out and he reported that with only a rough tune, it showed very good power potential and made more power on the same boost level than before (and this is with a lower compression ratio). Obviously he knows what he is doing with the AEM unit and makes incredible power with his Celica. I definitely appreciate all of his effort in trying to get the car sorted out.
I obviously do not have much of a clue when it comes to tuning these vehicles but what I do know is that for some reason, the ECU doesn't always agree with mods as evidence from my initial tune. We expected to get around 275-280rwhp and ended up with 236rwhp. I would not think that the ECU would cause any more problems or interfere with the AEM unit any more than it did with the emanage as far as the throttle goes, but it will offer a lot more "tunability".
I am hopeful that we can get this to work and not have problems with the ECU throwing codes, and going into "limp mode" as Charlie mentioned. I guess we will find out in good time. Matt is dedicated to getting this figured out and if all goes well and the DBW doesn't cause problems, I am certain that I will have a well tuned high power Elise. How the 2006 ECU will respond is the big unknown here and only time will tell. That is the part that has been so anxiety provoking as I wish there was just a clear cut solution
I sure can not fault Matt for all his work, he is definitely trying his best and hopefully I will have real good news to report here soon. If I had a 2005 or if the Lotus ECU was more like the Celica's, there never would have been an issue and I would have a lot less gray hair. I guess that's what I get for not being able to leave well enough alone.
