I scroll through the log and look at the timing figures in degrees, and where I dont like what it was doing I look at the RPM and then go up or down in the cell the map trace line passed through at that RPM.

My timing isnt identical from pass to pass, my ecu is always trying to change itself due to tables somewhere else.. but generally I am running around 14 degrees at peak torque and 20-22 degrees by redline.

One of my passes at a little less boost decided to randomly touch 25 degrees by 6000rpm. That right there is why I want a standalone in this car (ditching the VHR heads)... THAT type of crap is exactly how people on pump gas lose motors.
I guess its much different on the rollers. I have the Mrs drive my car while I watch in real time and then edit the values I don't like as we go. Makes it much easier with 2 people handling the setup. I can see why Greg and Seb do it that way.

Ill have to take a look at one of my logs to see what I am at. I am just curious as to how much extra you are able to get away with with the E85. Its good to know that as long as us gas guys stay out of the knock our bottom ends should be more than fine considering most of us are in the 500s.

I love threads like this!
