    I think the new XDF's and process is straight forward and easy enough for knowledgeable self-tuners, so as long as you have a reputable tuner they should have no issues at all.

    @V8bait just tuned a car live in real time with this new flex fuel offering on the Precision Raceworks LIVE build that was aired on YouTube this weekend.

    If you have a reputable tuner who actually understands tuning and can tune from scratch you won't have an issue.

    If your tuner is one of the copy and paste guys with limited knowledge other than how to tweak individual tables...they won't be able to do this for a while.

    For those that are running JB4 BEF, using JB4 app as monitoring.
    Does it still work?

    It will work, but will require a new BEF that Terry will have to make in the appropriate format. Also, JB4 software will need to be updated as well if they want to pull in E% from the DME.

    Thanks, this was essentially what I was asking.

    Thank you. So I wouldn't need to buy a standalone ECA because it's all inclusive?

    Reason I asked about the ECA is because of this. I wasn't sure if it was a standalone.. :

    JB4 users still need an ECA, but they can continue to use a JB4 if they wish was what I meant.

    It's pretty straightforward and he's going to release some tools to make it even easier. The time consuming part for me was having to verify every single axis breakpoint and table by hand as some have been repurposed for space, and I only got the software the night before lol. With the tools he's releasing, a lot of that will be automated, and once you finish setting it up you're good to go. You can still cheat a little with boost control using airflow adder, but this does require a good understanding of boost control and the base wgdc table.

    I think they've done a very good job with this.

    Any idea when the Motiv ECA will be availabe, then?

    EDIT: Nevermind. Found my answer. THIS is what I was looking for about an ECA.

    There was confusion on my part because I read the below answer and thought we would need the Flex Fuel box + Standalone ECA. Someone had asked about using another company's ECA, and this was Jake's answer.

    Hi, I'm new here. I've just read most of the 24 pages, it's a pretty awesome news.
    This is exactly what I was looking for. My car is completly stock, stock turbos, catted DP, stock intercooler, new HPFP, new coils, new spark plugs.
    What do I need to go Flex fuel stage 1 ?
    Am I good with that ? :
    - Motiv Flex Fuel Box
    - Motiv Ethanol Content Sensor Kit
    - Stage 2 LPFP (Boost Concept DIY Kit)
    - And of course MHD and all the modules

    Thanks

    I hope I'll be the first MHD Motiv flex fuelled french guy !

    I can't seem to find it but I thought I remembered reading that due to ram limitations some compromises had to be made are their any features that are lost with the flex fuel maps?

    I would answer, but @JOEinSD doesn't want that so I'll just say you can find this answer obscurely via some creative google searching where it was listed on another board and has a link to a social media post that directly answers this specific thing.

    Or you can watch the 20hr video of the live install done by Precision Raceworks where it was inferred in the description about 13hr's in but not directly answered.

    :tearsofjoy: Love such an appropriate smart arse answer!

    Now, I'm not sure if Joe internets much so let's give him a break and help out Mr Rob09 if we can.

    I was thinking previously about the length of the video as well and that some sort of table of contents would be very handy. Gonna take a lot of effort to pull that off though.
