This is for my GVR4.

Car is Link tuned, ran 11.x WOT all day long with no knock after I replaced a CEL knock sensor. The car saw 18* max timing on 22lbs with a big 16g and 0 boost leaks (Tested up to 25lbs) That was all fine until about three days ago. I went to go for a quick WOT or two run to see if I can pull a little more timing out of it but once I hit 40% throttle or so the car falls on it's face and feels like I'm brake boosting. I had a friend follow me when I did it and he noticed bluish/whitish flames shooting from underneath my open o2 housing (I normally run a full 3" exhaust but have the downpipe unhooked because I pulled the transmission recently).

So as of now I'm completely stumped. The Maf-trans is set for 450's while everything else is zeroed out. Link is set up for the 550's with the correct global and deadtime. Timing is -- dead on even with the CAS. Plugs and wires have been recently changed, does this sound like my CAS is going out?

HELP!
 
Compare your log when this happens with your old logs, pay attention to maf, airflow and IDC.
 
I'll see if I can find one of the logs I made when it was doing this in comparison to the good runs, hold on.

Not quite sure why my injector duty is 100%+ WTF These are 550's on a rewired 190 with a big 16g, no way it's outflowing those!

There we go, both logs are up. I figured out what it was though, Clutch control on DSMLink was setup wrong, but I figured it out right after I just looked through stuff.

Now another problem though, the car feels funny at WOT even with everything fixed. I uploaded everything from the same good log that I just posted up and it doesn't feel all too great. I don't think the relay for the rewire is installed anymore, :sosad:
