MREV2 & spacer installed, dyno failure. Help!
#16
I don't know anything about dynos so if it's normal for those lights to be on during runs, then just ignore my post! I thought you meant it would just light randomly when you gave your car gas.

Hi Dave,
It was good talking with you on the phone today. I'm always available to help out.
If your baseline was significantly lower than the average Z or G measured on that dyno, it suggests something else is going on. Particularly if each successive dyno goes down. Assuming a proper installation, the MREV2 will never cause results to move around.
Have you been able to find anything new? I would check the catalytic converters to make sure they are still working good and also check the other things we discussed.
Maybe we can figure out more clues from your other test plot's and the plots generated by similar Z's and G's that were tested on that same dyno.
It would help to have a relative reference point.
Also, here are the links we talked about.

Their dyno isn't broken. Ran 3 other cars on it just fine since. I ordered Cipher as I beleive I have a Gremlin in the wireing!
My car runs great on the street, just added MD's XYZ pipe and the closeout Stillen single exhaust and love the way it purrs now. The bump in topend power dosent hurt either!!

It has been a while but I am positive my slip light came on and pretty sure that my ABS illuminated at the end of my 4 runs. It was almost 2 years ago but my power output was not affected and was pretty standard numbers for running on a dynojet 248.
To the OP, you showed the pics of the plugs but did not mention if they were replaced or simply pulled to inspect. If they were replaced, did you use OEM ngk plugs in the stock heat range?

Yes, I used stock OEM NGK replacement plugs.
Updates are:
I went to another shop and had a smoke test preformed on my install. No leaks were found and the car deffinately feels stronger. I've added the XYZ pipe with resonator and a Stillen single exhaust.
Car runs really good but I still have some knock at WOT. Front brake pads are paper thin so I ordered some Hawk pads.
Also ordered Cipher to datalog but havent received it yet.
Still think I have a gremlin somewhere but I know that it has nothing to do with Motordyne products!

Update.
Tried LFR5A-11 copper plugs. Gapped to stock. My pinging went away! Talked to the guys at UpRev and Tony at MotorDyne and came to the conclusion that with the fuel available here, Platinum plugs just dont work!
I will go back to dyno again soon but my butt dyno likes the feel and obviously so does the ECU!
I do need to get a tune though as it's a little to lean.
