Help with VAFC2
Hi,
First of all, I'm not sure where to post this. It was either here or in the 5th Gen. But I think I'm in the right section. I own a 2002 maxima auto.
I just order the Apexi V-AFC2, and after reading around it does not seem to be to difficult to install.
I actually called a shop to quote me for the intallation, they wanted $237.00 for the wiring, mounting, setup, etc... The dyno tune session runs $150.00. After I saw the price, I'm just going to try and install it myself.
I searched for a diagram, which I found this one.
EDIT: I just notice this one is for he SAFC
I believe I saw another diagram that was bigger and easier to read, but I can't find it now.
I'm in the list for the new Cattman headers, hopefully they will be shipping soon. Also I decided to get my send my ECU to get it reflash L-SPec at TechnoSquare Inc.

I went with the VAFC2 since it has been posted that its better due to its 24 tuning points. I read through some of the post that there were people switching between pin 73 to 83 for the throttle because it was displaying 93% instead of 100% when WOT.

Also there was some hesitation when pressing the gas pedal, the car would kick after 1 second later it was said was due to the VAFC2.

Has there been solutions for this or workaround?? I really will apreciated for any info, advice you guys gives.
EDIT: I found the bigger diagram.
Thanks,

Btw, I was the only one with issues, Sloppymax, Steven88, and Deckdout2 had no issues with their VAFC-IIs. In fact, I mailed my VAFC-II to Deckdout and it worked fine on his car. I also tried another VAFC-II on my car (with the same harness) and had the same crappy results, which is why I concluded the harness or connection was messed up.

Once my carpet was in the way which prevent 100% throttle but mainly the Unit has to learn what 100% throttle. This is performed by hold the throttle all the way open for 10 seconds, then closed for 10 seconds, repeat atleast 3 times, keey an eye on the display it will show when it reads 100% throttle.
ninja edit: now that I re-read I realize this was somewhat of an issue on the 5.5th gens

sorry not the voltage the throttle % read out on the VAFC2. the voltage was stable. After WOT -> 0 throttle -> WOT etc a few times the VAFC2 read 100% every time I floored it. this proceedure is outline in the VAFC2 pdf on apexi's web site.
