Im headed to the dyno tomorrow to tune my Emanage on a Comptech with 7 psi. I was wondering if it would be all right if the vtec engaement point was not changed? The reason is that my tech hasnt wired up those wires on the Emanage yet.

 

I never messed switching the VTEC crossover RPM, when I used the e-manage. you won't be loosing any peak power as the HP peak is well in VTEC.

 

Ok, just making sure. I just heard a few of the guys changing it to 4400 for FI and getting good results. But would I gain more mid range if I did have it tuned with the vtec engagement?

 

Yes you would gain more mid with a lower vtec point, as long as you added the extra fuel aswell. Believe it or not though...some F20s like lower vtec points than others. Mine is set at 4900 because any less and there was power loss.
