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,

Don't think there is a way to tell besides reading advance and then comparing with the different tables in ls1edit.

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.
