Hello everyone! I've some strange problem - I've bought a Index computer from AUTO M52B28 and full flashed it with MANUAL file. When start my car when it's water temp is cold as possible, it revs up to 2-2.5k rpms. I don't have this problem with other computers (like M52B25 or M52B20 stock computer), the file I've flashed is full stock, I've tried flashing other files from the forum, but the same thing happens every time. Also when I attach this computer to my other car with M52B25, it keeps very low idle rpms (below 500 I think). Again tried to re-flash it, delete adaptation, tried to use other full flash file and nothing helps.

Can anyone help?
