For the 94 turbo 480 you are looking at a blue chipped boost ecu and a green label engine management ecu. Both of which are for sale as a set ( as doingitsideways referred ). Funnily enough there are 2 sets available one with a Robou mod and one with a Richmod the performance characteristrics are slightly different but both give the same top end performance. The biggest difference is in the prices being asked with the richmod being an eyewatering£200 and the Robou mod coming in at
well less than £90.
I am currently selling the Robou mod and will be placing an ad in the 480 club europe site soon.
My unit came from a 94 M reg 480 turbo.
