Hi Festy, nice to see ya here!
Ok guys, here's how I ended up with 4 bad ecu's (p/n 0261203301): The original one that came with the engine, was damaged by the garage guys, when they kept switching batteries, having installed the engine in my mechanic's car for break-in ...trying to find a good battery, strong enough to start the car. Thinking the batteries were good, they ended up playing around with the relays... . With all that boosting and sparking around, ultimately, the ecu died (that's #1). I then bought one from German ebay and ran the car (that's #2). A friend sent me another one which was inoperative (that's #3). I sent the two bad ones to Germany for repair, but only one was repaired. So, at this point I had 1 bad and 2 good ones. Upon returning from a track weekend, one died inexplicably -the only mystery death so far imo. That left me with only one good one. I figured I should have one spare for each engine (the 3liter and the still-to-be 3.2) so I looked around and found one more in Holland (#4). At this point, I decided to give the only two good ones to a friend who does chipwork so that he would copy the dyno-chip on both. ....When I got them back, none worked; dead in the water! Once more, I found another one in Holland (#5) albeit p/n 0261203834 (the one with the immobilizer but modded to non-immo by Squadra Tuning). So now the car has a std ecu and the 4 bad ones are in Holland. When they come back, I'll take them to my dyno/mapping guy so that he can copy and install the chip he made on them all. Sorry to cram all this stuff on you all but maybe some of you guys needed a laugh! Believe me, I'm not in the least amused; you can imagine all this has cost a serious bundle! As a sideline, I also got an Emerald K6 and will sometime have this wired in also -not in a hurry though at this time to play with it.Like I said, summer is still here and things are moving very slowly.
Festy, you may have something there with this LDA stuff. Its in the manual but that's all the info there is. Your reasoning sounds plausible but I won't try any inputs to the LDA pin until I have 4 good ecu's again....get my drift?
In the meantime, I'll try to scrounge 600€ for the 24v cams with M3 profiles. I want to see what it'll take to have them fit in the spare heads. Its not just a bolt-on thing...I suspect issues with guides and springs for starters...When I have something, you'll hear about it!
