Can someone provide me the best approach for ECU reset? I need to deal with the "sluggish shifting" issue...

Thanks!

If you are after ECU reprogramming, you need to go to a specialist. Not something you can do by yourself.

It's gonna cost you some heavy bucks, I'm afraid.

Otherwise head-on for your dealership and make them check the unit, but guess you have a problem with the CC handling out-of-the-box rather than malfunctioning.

Dear Rick,

I too am noticing a slower gear change since getting my clutch replaced (less than 100 miles ago). I'm told that the mating surfaces need to season, which makes some sense. However, I think it is also true, and relfected in prior posts, that when the battery is disconnected for any reason, the ECU has to relearn your driving habits. I think the only way to start from square one is to again disconnect the battery, then drive aggressively for about the next 50 to 100 miles. There is a convenient way to do that, which is simply to turn the battery disconnect knob which is located to the left of the battery (black knob, about 2" in diameter, marked with arrows) When we Eurotek customers received our ECU's back, if I recall correctly we were told to redline in every gear possible during the initial 100 miles. Now that is likely a more extreme instruction, given that those ECU's were wiped clean and reprogrammed, but you get the picture. Apparently, certain parameters are set by the ECU based on how we drive. Just my two cents. Good Luck.

I posted about this last week...

the trick is to drive aggressively the first miles after shutting off the battery power overnight....don't wait for the first 50 miles, do it in the first miles, you will be happy.

Done! And it did seem to make a difference. The near-violent, tranny-thumping shifts have returned.

This whole process has also taught me that the clutch programming is "two-phase" - it clearly shifts faster above 5000 rpm than below, which makes sense, given the different downshift model when above 5K.

So, for max performance, do the obvious, and let 'er run up past 5K (or 6500, for that matter!) before shifting.
