BEF Tune Questions For 2022 Stinger GT2

[InvestorZ_GT2]

Hello,

I will be getting a tune her soon. I have one setup with Sleepy Tuned. If I am wanting E85, I have a JB4 and looking at getting a CPI. My concern is if I don't have E85 available. What do I do? Is this a scenario where you should have have the ek1 with you and flash back to stock? What about the CPI? How will that work when you are not running E85?

I don't have a JB4 currently, but I believe it would just be switch which Map you are running.

When I spoke with him he said the jb4 isn't needed with his tune. It would be more used for a logger.

Then you need to talk to sleepy.

I thought you needed to buy the hardware to determine mixture, and then use the JB4 to switch to the map for blended gas/ethanol

I would rather get a tune for regular pump gas, and then use JB4 to manage ethanol mix.

This way, you can always just switch back to no JB4 but use regular gas. Unless you drive a lot, and are always running through gas.

To run e85 don’t you need it to be tuned for that? Jb4 turn can’t do e85?
