edge Posted September 22, 2009 Share Posted September 22, 2009 Have you had the ecu mapped to your cars spec? Link to comment Share on other sites More sharing options...

edge Posted September 22, 2009 Share Posted September 22, 2009 When you buy an ecu the come with a basic map to get the car to a "mapper" ot tunner who then set up the ecu which includes fueling, timing etc. Driving the car or just running the car for long periods is a very risky thing to do. For example you drive the car and the ecu needs to know how much fuel to supply to the cylinders at various engine speeds and various amounts of boost. Not having enough fuel when on boost will causes detination/pre ignition etc which will lead to a piston melting, ring cracking and so on. :boom: Please trailer it to a place that knows what they are doing. Is it the Apexi PFC? Link to comment Share on other sites More sharing options...
edge Posted September 22, 2009 Share Posted September 22, 2009 When they map the car they normally do it on a rolling road or you may see someone driving it and the passenger with a laptop adjusting things Link to comment Share on other sites More sharing options...

Thorin Posted September 22, 2009 Share Posted September 22, 2009 What is this Apexi unit you've had fitted, are you sure it's not just an AVC-R boost controller? Link to comment Share on other sites More sharing options...
Thorin Posted September 22, 2009 Share Posted September 22, 2009 mate, i´ve been told that its coz of the second turbo, do you know where i can get hold decent turbo, its the second one I doubt that very much, second turbo should come in at 4k. Was everything working fine before they got their hand on it? Link to comment Share on other sites More sharing options...

Wez Posted September 22, 2009 Share Posted September 22, 2009 Didnt think the Apexi ECU worked with autos Link to comment Share on other sites More sharing options...
Thorin Posted September 22, 2009 Share Posted September 22, 2009 Didnt think the Apexi ECU worked with autos I'm guessing it's just an AVC-R. vipprotuning : Check for error codes and let us know what you get http://www.mkivsupra.net/vbb/showthread.php?t=35920 Link to comment Share on other sites More sharing options...
