High or Low Octane tables w/ ATAP Hey all -
My car has been running rather sluggish and has been idling roughly recently. During acceleration there is some missing and some pinging. I suspect some bad gas. Is there any way using autotap to check to see if your ECM is using the high or low octane tables? I topped off with 94 already, and things may have gotten a little bit better but i think there's still alot of bad gas in the tank.
Thanks,
-T

Re: High or Low Octane tables w/ ATAP Well, if you're getting much KR you can be sure that it's in low octane mode. If you're getting 0 KR then you can rest assured that it's in high octane mode.
