Rocket III - fuel up to E25 ??

[RockyIII]

Hi everyone, I was wondering if there is any way change a tune from fuel up to E10 to fuel up to E25.

I'm just asking because I'm here in Brazil using fuel 89 ron/mon E25 (about 25% ethanol mixed in). So I don't exactly know what effect if any this has on the running/performance of the engine.

I'm currently using the 20050TOR_dyno tune.

If anyone has any knowledge on this one I'd be grateful to hear from you. What makes a tune E10 and what makes it E25? Thanks.

just out of interest, I compared an E10 and an E25 TORS tune for the 675. I noticed that the ignition tables are higher and all the fuel tables are higher on the E25 tune. Would this translate to an E10 tune for the Rocket in that I would need a similar adjustment for optimum performance on my E25 fuel?

I'm just interested because for the final time I have been testing tunes and I can definately say that for me and using E25 89 ron/mon fuel that the best tune is the 20050Decel tune. It just runs great, no over revs but a slightly slow wind down back to idle, no jerkiness at all, just seems right. So in this case with an E10 tune, I don't have any problems running E25 gas.

Kind of a mystery to be honest.

Thanks guys, Ben.
