Hey all,

Looking for some feedback on this log. Done in 4th gear with a shift to 5th. Car is currently with AA catted ********, BMS intake. Map 4. Thoughts?

Logs look pretty normal, but trims are maxing out. I would not recommend adding any ethanol due to the maxed out trims.

Thank you! What options do I have to get the trims in good shape? I’d love to run map 5 at some point but need some guidance as ways I could achieve that.

Are you currently running ethanol? If so, what percent ethanol are you running?

Nothing currently but there’s a station nearby. There is a royal purple octane booster in the full tank with this log.

Try map 5 and upload a log without any E85. If you want to run E85 flash the BMS BEF.

It looks like you are maxing out trims and are starting to lean out still. I would start running map 4 instead, to keep things safe. Please upload another log in map 4. Thanks!

Trims look much better, still maxes out at start, but AFR's never went lean. Still too many corrections. Go ahead and run more octane, or try a log in map 2 and upload it.

Tried a station close to work that had E85 since I needed to fill up today. I put in 2.1 gallons of e85 and then 92 on top of that. (Thatís the best they had). The station closer to my house has 93 and e85.

The timing looks a lot better here and trims look a little better also if Iím looking at it correctly. AFR seems to move around a lot, no?

Log looks good for the most part. Trims max out but you never end up going lean. Just something to watch for. Try to not put in more than 2 gallons of ethanol for right now. Can you get another log but in map 2 next? Thanks!
