Since the AEM plug and play is still a few weeks-months from the release date, I decided to try a Apex i VAFC.
I know they are out dated and wont work as good as a real management system but some thing is better than nothing at all right? I gained power on the entire band by just adjusting the air fuel ratio and changing the VTEC transition. My J motor ran really lean from 1100 Rpm to about 3700, then ran rich from 3800 to 6300. The bonus part is bought the VAFC for $25 so say what you will but I saw and felt the imporvment all motor and on nitrous.
Big thanks to Erick and willy at Erick's racing engines for the long hours of tuning sqeezing every last bit of power, Brian @ Hasport for making such great mounts, KRIZN Industries, John @ M&H tires, Mike @ High end auto sports, Frank @ F&S Clutches (everything breaks but the Clutch Frank) Fonzee for all the help and putting aside his V6 to finish mine.

This is the all motor Horse power differance.

Before VAFC With VAFC
125 3000RPM 125
160 4000RPM 177
205 4500RPM 215
230 5000RPM 252
275 5500RPM 280
283 6300RPM 290

This is the all motor Torque differance.
Before VAFC With VAFC
200 3000RPM 211
203 4000RPM 237
220 4500RPM 243
240 5000RPM 263
253 5500RPM 270
230 6300RPM 241

That's a nice graph but, Ericks Racing? That fool is a punk and a rip off artist. He jacked my friend out of his 2.0L Ls/vtec motor and took his money. I would never go to Ericks...rather go to the best and that is Church's. Anyhow, pics of setup?

P.S.
This is information only so
negative comments welcome.

Sorry about your friend BTW.

Any how the motor is a stock J35, stock block with match ported cylinder head and intake manifolds.
I did add a 72mm throttle body and had it matched ported by portflow (Thanks Tom) other than that it's just a J35 on juice.
