ECMlink timing lowered drastically duringWOT

I turned up the boost only 3 pounds. Did a 3rd gear pull, car started to sputter. For some reason the timing dropped big time to. Was that due to the sputter? Possible i fouled out my spark plugs? The drop occurs at 77 sec on the log. I also got a bunch of knock. Previously i did a pull at 20psi before i turned it up and had no knock.

Your timing dropped because you're knocking like crazy and the ECU is trying to save your motor.

I don't see any logged boost or a WB, so it's hard to tell why. If BoostEst is anywhere close to correct (which it may very well not be), you're somewhere around 23 psi. Try dropping the boost and getting rid of the knock for starters.

It also looks like your TPS is out of adjustment, since you are only at 92% during the pull.

this log at 414sec is where i started to do a 3rd gear pull. This was at 20psi

That one looks much better. What kind of fuel are you running, and what AFR is your WB showing? Your timing advance is targeted pretty high at 20*.

It looks like you haven't done any MAF calibration at all, and based on BoostEst it needs some...if you are really at 20 psi of actual boost on your gauge.

You need to log your WB AFR and/or actual boost. You need at least one of them (preferably both) to take full advantage of ECMLink.

Im running E85. Wideband is around 11.7-12.3. I have a phantom auto meter and that wideband wasn't a choose on the ecmlink. I don't know how to set the wideband up or boost on the ecmlink.
