Well, I finally got my socketed ECU back yesterday, from Kevin at EFI autoparts. It looks like he did a neat job, and only $120 + return postage. It took him longer than expected to finish as he had to go away unexpectedly, but I'm happy with the end result.
So today I swapped the ECU's over (simple 5 minute job) and went for a quick drive.
The first thing I noticed is how much earlier in the rev range the turbo develops boost.
Beforehand I had to rev the engine to about 3000 rpm to see 15 lbs on the boost gauge, now I'm getting that at around 2000 rpm.
I only had a chance for a short drive today, but it definately has an improvement.
I think the EGT's have increased a little bit, but not too badly. I saw 600 degrees, but that was pretty hard acceleration, uphill, with a trailer on at 90 odd KMH.
Overall, great job Rumpig. It's a bit hard to know exactly how much better yet because I just can't help flooring it everywhere! once the newness/ novelty factor starts to wear off I'll be able to judge the fuel economy etc.
Thanks Rumpig for a top job.
P.S. have you named/numbered different versions of tunes as they are evolving?
