I have been searching everywhere for how ppl with the old platinum pro tuned with E85 and used GM flex fuel sensor ..

Cant find any details on the GM sensor used, if it was stressful as using the Plug in and Haltech flex fuel sensor...

I have a Utec which im wanting to upgrade as it can only do straight E85 but as soon as other fuel is mixed the tune wont work...

Will the Haltech Platinum Pro be in the same situation? For <500RWHP should i bother upgrading to haltech platinum pro if it cant tune mixed E85?


Thanks guys
