APR 104 tune octane

[aliencurv]

Hey cats, does APR's 104 tune mean C10? or unleaded-109?

It depends on what the octane measurement they are using is. If it's R+M/2 then C10 is 100, and unleaded-109 is 105.

But if it's Research Octane then C10 is 104 and unleaded-109 is 109.

Also, is there a newer APR stage-3 tune then the one i'm running? I remember seeing on apr's webpage that they had a higher output stage-3 tune but i wasn't sure if i'm running it. and i don't know how to find out. can i query a tune version with vag from a measure block?

Re: APR 104 tune octane

actually it doesn't really matter right now about the octane because i just spoke with jordan @ vp and he doesn't have C10 in stock. and i got a good price on the 109

You are on the latest tune... you'd have to check with them about gas. I doubt they would do a leaded gas program though...VP 109 will more then suffice.
