I have a pig rich problem (950>1003). Because this table has the highest percentage addition, is this the main table to adjust down for pig rich?

I actually read the Help on Tuning that came with TunerCat and it explained the calculation to be used for the 3 tables that combine for richening. Mine calced out to 11.3 which is pretty rich so I'll jump it up to around 11.9 and see what that does

Anytime I'm messing with the PE stuff, I'll make sure that the percentages for 68-104 coolant temps are the same so that there is no variance in that temp range, and then I'll adjust the RPM table to get the desired changes I want.

Also I wrote a really simple spreadsheet for works that if you cut and paste the coolant temp and rpm tables into....it will calculate the air/fuel ratio for you. Only thing you have to do is tell it the % change in temp you want it to calculate it for.
If you or anyone else wants to try it out...e-mail me and I can send it to you. Like I said, it's pretty basic but it does all the calculating for you.

 

The spreadsheet thing was exactly what I was thinking (but I never had an excel class or really know how to do it). I was thinking of using the AFR table for changes because I'm blown and things change the most at WOT (100).

Oh, and I was going to keep those temp settings all the same and richening up over and under them.

Please, send it to me!
