Log question

[Mike810]

I logged map 0, 1, and 2. Terry at BMS said to add E85 to help with my timing. I will try that next. My question is even on map 0 my timing is bad it seems. Is this because I did several runs and the car is hot. I run 93 shell gas. Are there some people who can't run map 2 on 93 octane alone?

Im no expert but the timing doesn't look particularly bad for a map 2 log, Sure its not perfect but I don't see much above 3, which seems to be the threshold for issues or not. Your average ignition does seem a little low though. Maybe try a different brand of gas and on a freshly warmed up car? Your log doesn't look particularly bad.

Don't worry about corrections on map 0. Even stock cars do have some timing corrections due to gas octane, heat, etc....

Does this log look better for map 2? I put in a few gallons of e85. Can I try map 3 or 4 safely?

Yes 100% on map 3, as this map 2 log is very very clean, map 4 wouldn't hurt to try, take a log in it and see what happens, the JB4 has safety systems that will back down the power if you dont have the fuel for it.

Thanks. I tried map 3 and 4 just out of curiosity. How do they look?

Thanks

still looks good. I would run it. the amount of e85 you added seems to be doing the trick!

Yep, Super clean. I'm really jealous of all the places that have access to e85 at the pump. None anywhere in my state

I was disappointed at first that I couldn’t run map 2 with 93 alone and get full power. But I guess I am lucky that I have e85 here in IL,

well considering an e85 mix with 93 is cheaper than full 93, you're better off that way.
