Do any of you guys out Europe way fit programmable management systems to your cars?
Its not cheap- for me, a proper Haltech setup would end up costing $2k to install and tune, but it gives growth potential that a chip just cant- I mean, lets say you go the usual route of turbo power chasing:
Larger Dump pipe
More boost- obviously to a safe level with the factory turbo and injectors.
Your car at this point, would be pretty hot little thing already, but the "chip" (I think that Weber Marelli stuff is EPROM based) will only give you a real generic state of tune, whereas, with a full engine management system, you can tune the car to your individual setup- say you go and get some cams for it or something like that- youre altering the motor's ability to breathe at various rpm and load positions on the fuel/ignition map- with a system like Haltech, or upper end stuff like Autronic and Motec (Mainly used by professional race teams, or guys with a bit to spend!), you could rid the car of its AFM (Im not sure what the Weber System uses, but lets assume were talking L Jet GTV6 or Motronic 75Q), and really finely tune the Air Fuel ratios to match the cams/boost pattern etc.
Anyway- feel free to bug me if you have any questions on that sort of stuff- its quite big out here in Australia- with everyone from Rotary Turbos and Crazy Peripheral Port circuit racers, to Formula Alfa series racers and, even myself, and friends, with worked roadcars, throwing the factory management in the bin, in around 70% of cases.
