Just got my car back from the tuner after some major installation work, including new turbo, afm, injectors, cams, etc. I am extremely happy with the power output and response and the tune in general.
After lots of dyno runs we haven't been able to figure out the latency required for the injectors. The guys tried everything from positive latencies through to negative latencies. We have settled on what appears to be the standard for these injectors, 1.6ms, however the injectors seem to be dumping a bunch of fuel whenever I come off the throttle, which is igniting in the exhaust.
Anyone have any probs with these injectors in the past? Anyone know of a more appropriate latency for these injectors?
I have done a bit of research on the web and all I really come up with is 1.1ms or 1.6ms and both of these were tried and still result in issues.
