2019 Camaro SS Flex Fuel Tune help

Hi guys. I have a 2019 Camaro SS. I just installed my E85 Flex Fuel sensor from Skid Mark Garage and received my HP Tuners MPVI2 today in the mail. I was curious if there's a way to enable the flex fuel myself without having to seek out and pay hundreds of dollars to a local tuner to do that? Or if anyone's in the Southern California area, can you recommend a decent tuner that won't break my bank, or even a remote email tuner? I've been quoted no less than $1200 from most shops in the L.A. area and I think that's insane for just enabling the sensor (doesn't include tune for current mods). Any help would greatly be appreciated!

Turn sensor on, and turn on your dtc codes for the sensor.

I have a good flex tune

Holy cow that’s a lot for a tune...

Thanks for the replies you guys. A member on here who happens to be a tuner is assisting me with my first tune. Looks like I'll be sqaured away!

you have to consider that if your an auto there is several modules that need to be licensed

PCM 4 credits
TCM 4 credits plus unlocking service i think its 300
FCM 1 credit

that's 750 dollars and still no dyno time and no tuning
