E54 here in AZ, which MHD map is best?

[08 1ER]

Here in Arizona they stopped selling E85 some time ago. They now sell E54 which is a bit of a bummer but oh well. My question is....What is the best ethanol map to run on the MHD. Of the three maps 25%, 40% and 60% i'm guessing i can rule out 25% which leaves me with 40 and 60%. Can i run the E60 map with E54? Currently running MHD only.

Need help here. If i were to run e54 from the pump. How much e85 would i need to add to make e60 in order to run the mhd e60 map?

Just to confirm is that for all stations in the Phoenix area (I forgot about this & have been adding 4-5 gal of E54 thinking it's E85). I am pretty sure there are online calculators for computing octane content. I'll post the one I use when I get home earlier. You have the freedom to add more E.

Start with the E40 map. Log the car and if it's perfect, try the E60 map and repeat.

I believe it is all stations.

Sorry for my ignorance, I'm not really sure what to look at or what is acceptable when i look at it? Maybe i'm in over my head but i would like to learn so i can keep an eye on things?

Not sure if martial posted a log reading guide for MHD maps. Good place to start is hpfp > 9, lpfp > 50, wastegate duty cycle under 100%, and ignition changes of less than 3 degrees. If you flash the E40 map and do a log we'll help you out. But id suggest searching on google for a how to guide.

Log: 3rd gear at 2500 rpm through redline, shift and continue in 4th as fast as the road allows. Single gear in third is acceptable too. 100% throttle only.
