hi,

ive a few mods on my coupe, nothing too serious Gtech1 + prv, FMIC + SIP and exhaust but am in the process of aquiring a gt28r.

i know that i should increase fuelling and so am going to get a walbro 255 and do the wiring mod also.

am i right in thinking a gtec2 would be adequate for the mods i have?

I've heard a few poeple talk about "live mapping" but i dont have a clue what this is all about :?, i.e can the existing ecu be mapped or do you need aftermarket stuff etc, also what does this cost?

all help appreciated! thanks!

I have similar spec and asked GrahamL the same question about the chip, he recommended going for the GTEC2 but mine was running slightly lean mid-range. Get it on the RR when you have finished tinkering, if the fuelling is OK I would stick to the GTEC1 unless you want a bit more power.
