I'm thinking of getting a chip for my 225 and I see they all have like a 93 octane standard program. Here in Washington we're cool and only have 92 octane. Is this one octane point difference anything to be concerned about or is it negligible?

 

there is a big differnce between 91 and 93. There is only one company that sells 92 here and the rest sell 93. I think you could go either/or but a 91 chip would be safer to run

 

ya i'd go 91 just to be safe. btw, wha chip are you plannin on getting?

 

I'll probably go with the APR one, through Achtuning. It's not too far from where my house.

 

I live in Sammamish Smecker and I run Revo's 93 program w/o any issues. I bought the car in Jan 07 and chipped it 3 weeks later. No issues to report so far and it's a daily driver.

 

^ sweet, thanks

 

I think the difference in programing is timing advance. I think since you are continously running 92oct, i bet you have a extra degree or two pulled from the lower octane. Just a thought

 

Thanks for the input cincy......would there be any poor side affects from this besides losing a little power?

 

not really, the ecu will take care of you.

 

...or you could get a custom 92 octane program made. Not sure if you really feel like doing something like that though. But I guess it'd be an option. lol
