My Vortech s/c hasn't pinged on Sunoco 94.If the stock vortec s/c
is giving you330 at the wheels instead of the 292 that I had been told to expect...are you getting more than 360 at the crank? I haven't dynoed mine yet but it has turned into the car Honda should have made in the first place(along with wider rubber and stage 3 clutch).I had the dealer install it and they are going to keep my warranty on the drivetrain.

Jason, did you get the mail about Vortech FMU?
It is adjustable with a disc replacement. You basically buy this from Vortech, unscrew the allen bolts on the FMU and replace the old disc with the new one.
I am not quiite sure of the exact increased in fuel flow with the next step up disc but you know who to talk to if you have a question on this.

Itsn`t true that FI S2000 hondas should have a fuel ratio between 11.7 - 12.1??? that iwhat I have been told by Terry at Spool and UR


or SC S2000 has different A/F ratios? make sense?

When I get the Vortech installed I will be or like to floor it in all gears (except reverse)

It depends on where you measure the AF? before or after the cat?

Jason, how is the tuning going? Is the AF ok now?
Did you get a hold of Jenner's goodies?

If you are still running lean and can't get a hold of Jenner's stuffs. It might be worth while getting the upgraded Vortech FMU disc and lean the AF with a VAFC.

Just my 0.02
Good luck and keep us posted.
