I've just brought this G1 and it looks to have a new daughter board. The label on the main board looks to be newer but the numbers are still the same. Has this been upgraded to be PC tunable or does it still need to be tuned with a hand controller? Would it be possible to run this on a 4age 20v with stock ignition system and run it with rpm vs tps or does it have to use the map sensor and IAT?
