I want to calculate my motor's VE but am not sure how to compensate for my aftermarket cam. Anyone know?
BTW its a 224/224 563/563 on a 110* LSA.

 

What type of tuning software do you have? I use EFILive and it is very easy.

We don't really calculate our car's VE when we tune. We more or less reverse engineer it based off of feed back from an O2 sensor. We make the assumption that if the injector tables are set correctly and there are no other variables other than the VE table affecting fueling, we can manipulate that table to determine where a stoich AFR exists. I wish there were an easy VE "calculator" that we could use to get a solid base to work from. But, that's not the case...

 

Texas Instruments lol! I'm actually using a calculator to calculate my theoretical air flow.

 

I understand, I actually read the FAQ file up in the sticky posts about how you guys do this. I cant wait til I get HP Tuner's to get my VE tables staightend out. My AFR right now is in the 11's @ WOT.

 

What did you use to increase your fueling for your cam? Do you know if you have any positive fuel trims during cruise?

 

James @ RWTD did it and now I cant get them to respond when I post in the RWTD tuning forum. I figured I'd just bite the the bullett and shell out 650.00 for HP Tuner's. At least then I can data log more than just what I have input to the LM1/LMA2

 

Can't you lean out your WOT with the PE% adjustment in the Diablo tuner?

 

Its already leaned out as much as possible (-5.00%)
