Ya... not to be a dick, but I seem to remember another post where you were knocking my V-AFC formula because it didn't hit dead on your WB settings.. weeeeeeell... there was a reason for that. :-\

I'm saying your settings were wrong. I don't know if the WB was wrong, or you installed the ground incorrectly. The PLX is ground sensitive. Power needs to be installed as close to the ECU as possible. If you hooked it all up in your Engine Bay, and ran the display into your car.. Ya, your settings would be WAY off.

The reason I say your settings were wrong is because you leaned your car out futher than your stock ignition maps are. Essentially running boost on injectors SMALLER than 240cc.

46% flow rate difference (if you were using 450s) and you leaned PASSED that.. flowing less than 240cc injectors. That is why your engine blew up.

it also could have been timing related....correct?

im sure timing could have hurt it more, but running the injectors that far negative definitely wasnt good

yeah, i see what your saying....but assuming the wideband was correct, i wasnt ever going above 13.0:1 while in boost, I only have the timing retarded 3 degrees on the distributor, and .5 per lb on my btm....live and learn i guess. I have a hondata 3b on the way....hopefully this ---- doesnt happen again

that should have been enough retard for 8 psi

I would *really* check your install. I mean, honestly, that is enough retard to kill almost 10-15hp.

Your lack of fuel caused your ringlands to explode. I'm almost 100% sure. Pull the head off and have a look.

(..oh, and sell me the head, you're probably buying a whole new motor. ;) )

So I guess you don't want my hondata 2b? You don't need all those gay features in the 3b. :(
