I just have two quick questions as I am looking to purchase an OBD1 ECU for my car so that I can chip it and tune it with uberdata. Firstly, I was told that it doesn't matter if the ECU is for an automatic or manual because after it is chipped you will have control over everything. Truth? Secondly, is a P72 the ECU that I should be looking at? Do I have to get a P72 or could I go for a P28? Sorry as I am new to this whole chipping thing and I was cursed with the OBD2 to begin with.
