George, is it compatible with ROW 0010 ECUs?

Hi George. Thank you for all of the hard work. Did you do any beta testing on the 1.8tsi, and do you have any numbers for it? I know all of the facts and info are listed here, but will there be one in that engine section as well? Thank you again

I will create a dedicated 1.8T thread on the other section.

What's your recommendation for mixture percentage? E20? E30? Or is that determined on a case by case basis?

I also have the option locally of using 91 octane with 0% ethanol to be mixed with the E85. This results in a higher octane than if I mixed the E85 with the more commonly found 91 octane which already has 10% ethanol in it. Is it worth my trouble to use E85 with the 0% ethanol 91 octane, or should I just not worry about it and use the E85 with the 91 octane which already has 10% ethanol? Unfortunately, straight 93 octane gas isn't available anywhere near me.

Not more than E30 is needed.
There are tools online that can help with the ratios.

I was just about to place my order. I was going to order the JB4 connect kit as well. There are two options one for BMW E series and one for the F series. Which one should we order for VW?

For Rev1 unit E series for Rev2 unit F series.

To identify what unit you have check in the JB4 upgrade manual.

George it says you need a receipt to get the full $75 core charge back. All I have is the order conformation in an email from BMS. If I print that and include it with the JB1 is that enough?

I asked the same exact question 2 days ago, still waiting on response from George.

Hi George, if I buy a JB1 and the upgrade concurrently, will I still be eligible for the $75 core refund? Alternatively, when the standalone JB4 units are available, will they be only $50 more than a JB1 as well?

Hey George, just wondering if you were going to make any video instructions for the JB1 - JB4 upgrade.

Written instructions are my bane, terrible anything written. Just wondering, thanks.
