MHD 93 OTS map on E25?

[swrdply400mrelay]

Searched and couldn’t find the exact answer to this question.

I live in SoCal so we only get 91 ACN, but there is decent access to E.

If a stock fuel system can run up to E25, which happens to be 93 octane based on some E calculators I used, could I run MHD the 93 OTS map with E25 and do so safely?

I don’t have a flex fuel sensor yet, but plan on it in


TIA!

It might effect the drivability it might run rough, but the ecu will compensate for the difference and would be safe to run but not recommended.

it’s easy to build a custom tune similar to ots 93.

dm me your rom id if you need help.
