Hey, im abit confused about ECU's atm, are they retunable or not? Im planning to swap to the P28 ECU for a 'mini-me conversion' and i always thought that factory ECU's were unprogrammable, but everyone is always saying P28 are a good choice due to easy programability etc.
So, is the actual P28 ECU reprogrammable, or am i totally wrong here?
Thanks
