Thats what i meant, when i get a stand alone ECU i dont care about extra power as much as tuning the boost line...sori for not explaining it better...down the track after i have invested in a house etc i will look at getting a standalone but for now im sticking with the GTX jspec ecu...should keep me happy for awhile, after all ive kept the NA for almost a year...its still fun..hahaha

the vf8, you would have 5psi~ by 2500 and it would be in full swing by 3.5k
the vf8 came on harder and stronger than the vj20,
10 psi on the vf8 felt the equivalent of 14psi on the vj20
downside with using a vf8, is that you'll be lucky to get anything more than 11-12 psi out of it before the boost cut kicks in for you
that was the downside,
10psi the vf8 is only just starting to wake up and get ready to rumble..
I could imagine 16~psi on the vf8 would make it an animal  |
Hey Zero, did you have any major traction problems with this setup, i know being a totally different car and all but this was one of my main concerns with the setup i wanted? People have been telling me ill spin the wheels everywhere becaus ei want response over max power...why did the VF8 hit boost cut with 12psi, doesnt the ECU handle 14 or is it actually measured by the amount of pressure and not the total psi range? this is interesting...
