I just recieved my sct-2 back from brenspeed today with some newer tunes. I live in oregon and we only go up to 92 octane and I wrote tthat on the list I sent but on the sct it goes, 87,89 and93. Is it safe to use the 93? I am going to call him tomorrow and see for sure. I had to try it and it was a night and day difference from his original tune from about a year ago. Just wanted some opinions, thanks, Brad.

Its prolly OK, but listen real good for pinging.

I wouldn't do it. Just wait until he sends you a 92 or you get the OK from him to use the 93. Once you get ahold of him he can email you the tune very quickly.

this is a dumb question but was does pinging sound like, I can't hear anything over the slp lm's.

RCT06GT

It might be hard to hear over your SLP's (I know how they sound ).

Just give him a call bright and early tomorrow and he can sort things out for you in no time. Remember he is in a 3 hour time difference zone then us. You could get it all situated out in less than 20 minutes.

would it hurt to put the 89 octane tune in with 92 octane gas?

Nah, shouldn't hurt a bit.

I talked to Brent when I first got my tuner many months ago. I asked him for a 92 octane tune as well. I my area we can get 93, but not all stations have it. Some have 92, so I wanted to be safe in that regard. At the time, he told me on the phone that it was no problem, I could run 92 octane on the 93 octane tune.

Also, I doubt you will hear any pinging. The engine has a knock sensor and will automatically adjust timing if you have low-octane gas. You won't be getting the performance you otherwise would have, but it won't hurt the motor.

Check with Brent to be sure, but I think you'll be fine.

Thanks for posting this question. I'm in OR too and was wondering the same thing.

I haven't had time to get back with Brenspeed to request a 92 tune so I've been running the 91 tune that came with the SCT, using the 92 gas. I was thinking about flashing to 93 this weekend to see if there is any pinging and/or noticeable difference in performance.

From what I've read in other posts about octane it shouldn't be a huge deal either way but I still think I'll request the 92 tune.

Thanks again.

Trust me, your pinging won't adjust itself. It will be hard, get a passenger to listen with you. If your running 92 octane with a 93 tune, chances are you will not hear pinging till between 5000-6000 rpms. It sounds like a BB in a tin can being shaking faster then you can possible imagine. I ran 3 tanks and finally told Brent, he said pull the timing out about 4 degrees, or he would send me a new tune. Brent is awesome, run the 93, listen for pinging, and let him know what gas and rpm you hear it at, he will send you a new tune within a week, and mine worked perfect!
