Catless dp on MT

Has any MT's tried out the MHD Flex Fuel Tune. I'm wondering if the issues get fixed if the tune knows the exact ethanol level.

MT flex works fine but no that is unrelated.

It just auto-interpolates between the pump gas, e40, and e85 maps.

I'm getting ready to MHD my Catless MT Supra but was starting to hesitate after reading this thread. I'm in SoCal, so we have weak 91 octane. I'm wondering if I'm better off with the stock tune or getting the flex fuel sensor if it avoids the issues stated with the OTS Maps and shifting.

If it auto-interpolates between those OTS maps, then the issues would still pop up, won't they?

Probably won't have much of an issue with 91 tbh, issue seems to be worse on maps with higher timing.
