You can have your ECU tuned to run the engine on pump fuel no additives without knocking and give you the best hp you can get with that fuel. Don't just let the knock sensor mess up the timing on you like that. Take that sucker to UPRD and have them tune it on a dyno for reliability and power.

UPRD???

Ultra Performance Racing Development.

If I'm not mistaken they are the front company for G-Force tuning, an ECU tuner which is a branch of an OEM ecu manufacturer for many Japanese car makers. So they have all the codes/programs for the ECU's and know how to tweak them. At least that's how I remember it...

Anyhow, I know this guy who worked with them to tune his heavily modded sohc non-vtec with nearly 13:1 c/r and nitrous, he ran 13.58 with that! I think he used pump fuel too.

OK, I dug around for a bit. Forget what I said about UPRD, if that's the name of the place I'm not sure but I found the phone number for G-Force tuning. It's: 310-782-8278

Here's a write-up from a couple guys...
