@jyamona on ots cars you said full E85 drops to pump 93 levels. Does it revert to 93 boost and timing, or just lowered boost to prevent running out of fuel?

Most who have asked to be added to the beta group are getting protuned so that takes some time. Mang.vang is the only OTS user so far that I know of. Could really use some more!

You want any pro tune logs while working on the tune?

Not the best logs, I will get better ones next weekend. I will move from E30 (Stage 2+ 93oct) to E40 (Stage 1+ 93oct) for next set. I haven't installed DPs yet.

Can I flash my DME for the first time with the beta version ?
Starting with the 95 Stage 1 ?
And then going FF ?

If you have the v1.70 beta app, and have also purchased a pump gas map pack, ethanol map pack, and the flex fuel module, when flashing ANY v8 pump map FF will automatically be added.

If you wish to first flash without FF, you should flash a v7 map. Flashing an FF v8 will operate the same as a non-FF map though if you are just filling with regular gasoline :)

Your second run 3rd - 4th shift looks pretty good. Good boost. A little taper. Just one small timing correction. But your trims are very negative (-24). Did you do at least three WOT pulls to help the DME adapt?

We are going to tweak the interpolations some which will bring the stft inline on middle blends. Hence why we need the logs of the intermediate blends :)

What should it be?

When is the next update expected to address this issue?

Using the fuel scalar tables STFT’s are preferably tuned to be close to zero. -24 means the DME is reading too much fuel for the targeted AFR, and accordingly reduces the amount of fuel being injected. STFTs are on a scale between -34 and +34, so it’s best to keep it in the middle of the range (zero) as much as possible during closed-loop WOT.
