It's most simply done using a zener diode which will clamp the boost signal at a set limit making the ECU think that the boost never rises above a set value I have no idea on the ECU but for sre this is not a good idea on the ST205 as the ECU this signal for fualing and ignition timing. It works on the older AFM based 1x5 ECUs though and I'd guess the 7M is probably AFM driven One thing to bear in mind, the old 2.5 7M lump eats headgaskets for fun when running stock boost. I'd seek advice on a specific owner's club site before attempting to raise boost! |
