Default 1.4x edit, new IAT vs load table

found where some of my timing is going and i am real happy about it. in the old version, 1.2x, the timing vs load table was based on the map reading and IAT's it only went to 105kpa.

the new version is based on gm/cyl instead of map and the table goes much farther than it did before. you can see my adjustments and then where it is stock numbers, those numbers in the .76gm/sec and higher were not avaliable to edit before. here is a screen shot.

I helped Scream with his edit tonight. On his table, it had negative numbers on the left side and right side. Basically a penalty for cold or hot IAT temps.

I have backed those values off my tunes for a while even though my IATs never get any where near as hot as you boosted guys.

This timing thing not being dead on is kind of annoying me. On the same night with four back to back tuning runs -with nothing changed- I get numbers that differ anywhere from 1degree to 5degrees off of what it should be on my HOT timing table.

I figured I would graph it to see how accurate it was -not very
I have the Fuel Ratio vs. RPM Modifier table zeroed out too. I still cannot find the x-factor that is screwing with timing.

For S&G's, here's mine out of HPT. Untouched.

There's a bit variance in the IAT temp range...

Actually, those EDIT temps must be in Celsius.

Mine's in Fahrenheit.

What's Ken's addy? I will get him to send it to me since I am still under the update policy. He needs to follow through with what he sells ...
