Default Help me cure my Resets b4 NE Dyno Day!!!!

So my new setup is complete!
95 1.8L \ exintake cam in 90 Chassis
ETD Greddy 1.8L Manifold
Greddy turbo from the 1.6L Kit
3" racing mazda DP
FM Turbo Single Exhaust
460cc inj.
Toyota Cops
DIY MS
Oil Cooler/Filter relocate
Suspension/Brakes/Torsen/etc....

I really want to bring it to NE Dyno Day because i dont think anyone has ever dyno'ed a setup like mine, but i have one major problem. These Damn resets at 9psi or above....

Stuff i've tried:
Plugs gapped all the way down to .020" (feels the same at .035 and .020)
Tapped back of 1.8L head to ground the stock 1.6l ecu grounds
Stock ignition (to eliminate some sort of coil issue)
ran two extra ground wires from ecu to head
added an extra ground from battery to chassis in the trunk
Removed my LC1 to eliminate a noise issue
Cut the black/green sensor ground at back of head (its now reconnected)
Removed all the stock ecu ground ring terminals and connected them all to one copper ring terminal for ground.

What else is left for me to try before i pull out all my hair and fire bomb this car?

Posting an MSQ and datalog would do nothing, so why bother?

just 460's... I switched back to the pnptiming map (for safety) and took out 15% fuel in my boost cells. Seems to have helped a bunch but im not totally cured. Im going to try and pull in my afr's some more and then connect 2a,2b,2c,2d to one 10gauge ground wire and run it to the back of the head.... Hopefully that does. Anyone find a place locally that sells that noise filter? Seems nice to have...

you can always send your log to jerry or matt at diy and see what they say, but it's when you go richer than 10.0:1 AFR you start having resets.

I have not looked at your log or msq, but are you certain your resets are actually real resets? I get resets on occasion that are related to my USB to serial adapter. This is most likely due to the fact that Vista doesn't work 90% of the time with USB 2.0.

they are real resets; his SecL counter drops back to zero.

it takes all of 4 seconds to click the xls file and have it open up with MLV :P

I told you the ******* thing was too rich and every time you reset you were down at 10 AFR. I get no ******* respect around here.

ok here is a recent log plus it's respective msq. Still got one reset and i have narrowed it down to the aceleration wizard not being setup right... I think. Anyone tune there mapdot on a 1.8L? No tps FTL! Also can someone look at my CLT graph. Is that too noisy by the one reset that i did have?

I may be at dyno day afterall...
