If this is your first fill then you probably have some 91 left. Regardless cold cranking on E85 is all over the place depending on the E%. For example in Florida when it first starts getting cold it can take 4 cranks to start. Then as they switch to winter blends and lower the E% you will be back to single cranks. Then at the coldest part of the winter you will be at 2 cranks to start. Then as it starts warming back up you will be back to single cranks. Then they dial the E back up and you have a 65F morning and it takes 2 cranks. My point being that you can’t really count on the E% to stay consistent. I wouldn’t get too carried away with fine tuning because next week the fuel will be different from the last.

Well, that is my experience in NE Florida with GATE Petroleum anyways.

Yeah you're right, probably some old 91 left. Also I agree, given that E85 blends change over the year, I won't put too much effort into fine-tuning things unless absolutely needed. Like detonation on the track haha.

Speaking of which, do you track on E85? Have you had any issues with detonation or fuel starvation?

I haven’t tracked or autoxed the car since switching to E85. I’ve read that starvation is a bigger issue on E85 though. It needs around 30% more flow so I guess that makes it more prone.

Anyone know how to get rid of the "COLD START DELETE" on the tune?????? Not so much of a fan of the "COLD START DELETE".

Good morning, this is my first time posting on a forum so I hope I'm not breaking any rules.

My 2019 BRZ doesn't have a listed tune file, its CAL ID is ZA1JS10C. I emailed Open Flash Performance.. beyond that I don't know what to do.

[tomm.brz]

you bought an OFT unaware that nobody has a S10C tune and definition yet?
your best option is to try calid a s00c tune or k00g tune hoping it works, or go to ecutek

[DonnerParty]

I was completely unaware there was no tune available, had I known I definitely wouldn't of spent $500. I guess now all I can do is wait for them to release one?

I’m in the same boat.. waiting for my header to come in before I flash the car. Let me know what response you get from your email. I can’t imagine the tune would be much different (if at all) from the ‘17 tune

Right on their website they state "Now supports all 2019 models, world-wide!"

So I kinda figured my 2019 was supported.

Anybody has an specific map for Ace A350 and Ace Frontpipe decat?

I’m sure you’ve gotten a response by now, but the 2019 tunes are indeed on the website, just search your cal code and they will pop up.

[tomm.brz]

yes they added S10C yesterday

for ace, modify a v4 tune with romraider copying VVt timing from steve99 signature links

Can anyone help me out?
I’m trying to upload these new OFT maps
But I keep getting the same message

I’m guessing it’s automatically correcting my ECU software checksum?
I don’t understand why tho

Is it an old OFT?
I also had the dev121.dll error. Only solution was to flash back to stock, erase the tablet and start over.
But before you try the erasing part, try updating the template file
