just curious again....
i have just got my old sapphire back which had been smashed up.ive just had a look at the ecu and on the outside it has handwritten

boost pin 21 no flylead required.

it was quite a big spec car running 8 injectors,anti-lag etc.mapped by engine advantages-just wondering what it means?

would this ecu be any good for my rs500 as im using the engine to go in it,but want to use the rs500 inlet manifold rather than the wrc siamese one that was on this engine,or should i use the wrc one with the p8 and the loom it came with and the 8 greens?
