I just found out something. On 3 of my 360s with CS tcu. All of them has the same problem: if you drive normally and want to have a sudden acceleration, u want to downshift and put down your gas pedal. And at soon as you put down y your foot, your clutch will slip for a second or 2 , before it grabs nicely. I don't think I have any setup issue on PIS or close clutch position or whatever. And my clutches aren't worn either. I was hypothesizing to solve this problem you need a CS ignition ecu flash as well to make torque transfer timing corrected. Just a guess. So i'll try to flash one of my 360s and see if that solves the problem. Try it yourself , my comrades, u'll be surprised. ------------------ edit: i read a post a few months ago about this exact problem. But the article isn't mentioning any CS tcu flash. one of the poster said it has something to do with the clutch position sensor magnet getting old. I used to believe that. Until 10 minutes ago, I realized all of my 360s with CS tcu have this problem. That is a very improbable event for all 3 magnets to become old. But i'll try to flash the ignition ecu to find out. edit: also on upshifts, there's a noticeable engine up-revving during shifts , compared to Modenas with its factory-equipped TCU. That also has something to do with torque transferring I'd believe.
