I was wondering when you modify the tune with WOT fuel are the number values considered percentages? If I go 5 richer is that 5% richer?

Also with the spark advance, similar question. If I retard the timing by 1.5, is that 1.5 degrees or 1.5%?

Is there any way to get what values are of each setting as chnged over a stock tune to make the 87 Octane canned tune?

Thanks.

fueling is in percentage %...

timing is in degrees...

Is there any way to find out the values of each setting on the 87 Octane Tune as compared to stock? I'm having a few problems with the 87 Tune and making changes on it. I have the WOT pinging right at the shift and I tried decreasing the fuel 5% as stated here and also decreasing the WOT shift point but the actual rpm at shift on my tach was showing around 6200 while I set it to 5700, and I also still got the pinging.

I was wondering if there were a way to find out how far from stock the 87 tune values are so I can just modify the stock tune slightly instead of working off the 87 one since it doesn't appear to be getting me anywhere and it's not easy to drive 10 minutes to find a spot where I can legally WOT a 1-2 shift then reprogram and test it out a million times. Thanks.

I love the 87 tune I just want to fix this pinging issue, I plan on going custom tune come Spring, just need something with some safe performance til then.

Thanks.
