procedure? whats the fuse that i need to pull?

Pull fuse 6 and 23, attempt to start car (it won't, but drains any power).

Replace fuses and start car.

dont disconnect any battery stuff.

do what R Kelly said. 6 & 23. try to start car (it won't). put fuses back and off you go. no need to pull fuses and "wait". you can do the whle thing in about 30 seconds if you time it.

put in some race gas, reset the ECU, and get ready for massive hp.
even on a stock eCU the car loves high octane.

add an ECU/dp/exhaust and WOW will it like it. i coudl NOT believe the torque my car has started making since I got the downpipe and added race gas. 3k-5500k is unreal. on the freeway, it's wicked fast.

i can be in 5th, and just gentle throttle application produces NICE torque..i don't even have to downshift to fly past people.

Re: (Lake Powell)

Problem is with low octane fuel you would generate detonation and bam, dead R. Not worth it. There are a couple of ways to control pre-detonation

1. Fuel enrichment
2. low IAT- FMIC
3. Water alky injection- Lowers IAT
4. Ignition retarding- allows for more boost but with less efficiency
4. Reduce boost
5. Increase octane- slow fuel burn

Since the R can't lower the IAT or install its own water injection it just reduces boost, retards ignition and enriches fuel (limited), all which lower horsepower to protect against predetonation. I just wish we could all get better fuel. Unfortunately most cars today do not benefit from the extra octane like the R does. It just goes to show how tuned the car already is from the factory.

I keep wondering how it takes the engine to "learn" that you've put in higher octane. In other words, how necessary is it to pull those two fuses.
