I started tweaking my VE tables yesterday, and I noticed that the lower VE tables are pretty close out of the box. The BLM's are between 125 and 129, 129 being the most common. When it hits the upper VE table, the BLMS jump to 140-155. I'm adding a lot of fuel to the upper VE's. My question is this: how much is too much in tunercat? At 2400 rpm my values are in the 90's. That just tells me that when I get to the higher RPM's and the thing really starts gobbling fuel that the values will be well over 100. Seeing as to how the graph in tunercat only goes to 100, would I be better off increasing the injector constant and pulling fuel out of the lower VE table?

Its entirely up to you as to how much work you want to do. From what i can tell your going to need to rework either table HEAVILY... so take your pick...

 

I just answered my own question... The average increase was a multiplier of 1.15. When I tried to increase the entire upper VE by a multiple of 1.15, I got an error telling me that I exceeded the max value of 100. I'll try bumping the constant up by .5.

Did you already bump up the cylinder volume constant?
