thanks for the info lads.

i was looking at emerald ecu's after getting a catalogue with retro cars or something. rewiring the engine doesn't bother me cos i'll be changing a few things anyway. lookin for value for money and ease of use. i would like to map it myself but it's something i have never done. having said that i never did anything with turbo cars until i got my s12 and now theres not much standard left on the car.
nobody is going to show me how to map a car as they will be doing themselves out of a job so theres only one way i'll learn anything.
how does the bottom pulley work out with the position sensor? is there one for a det available?
hows the black legend coming on jackiefan?
