Some help please - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I purchased the OFT E85 equal length header tune for auto transmission from Wayno. First let me say I'm very happy with the tune. Runs great. I ran the default tune first for a couple hundred miles. Uploaded to Datazap. I thought I had to change to the lean 2% tune. So I did that, couple hundred miles, Datazap. Now after looking at the two, I think I should swap back to the default tune. Could someone look at the logs and give me an opinion please.

Lean map looks ke one to run however appears you ethanol Content is low hence the high negative fuel trims

Is this first tank of e85

If you don't hit the highest maf ranges in closed loop enough, it won't learn the correct values for LTFT for open loop, so you'll get that weird thing you just demonstrated with a leaner LTFT value that makes no sense. That's very common for 6AT because it shifts very early compared to a 6MT drier would. The newest files with new DBW maps will hit those ranges more often in auto mode so that should help. Keep the lean version, make sure you're on >= v162.

No, this is not the first tank of E85. Been using it for a while now on the OTS tune. So I'll stay on the lean tune. It looks like I'm on v160. Just checked your site. I'll download v162. Thanks.

Looks like your Stage 1 Tunes only go up to V160.
