    2017 3.5 E85 testing and data round 2!

    I tried to give the community some good E85 data on my last thread but was having issues with my chassis dyno so I stopped messing with the truck for a while. I’m finally taking delivery of my Hub dyno tomorrow so will finally be able to get some good tuning and testing done.

    I have just added VMP plug and play fuel pump booster and so far looks like fuel flow is good for full E85. Current mods are:

    Drop in air filter
    Mbrp 4” cat back
    VMP fuel pump booster
    E85 fuel

    Want to see what she makes now then add parts and see what before and after does. Will be getting upgraded turbos from Gearhead tuning as well. Stay tuned and hopefully I will have more to post within a few days.

    No these are the mid level 3500 series. They are about 50k depending on what accessories you get with them. Luckily the fine people at Dynocom were able to sell my chassis dyno for me so I broke even on these. Dynocom makes most of their parts in house so their dynos are less expensive but still high quality.

    Excuse my ignorance, but what does the fuel pump booster do? Is that for the in tank or the HPFP fuel pump?

    Woo boost is correct. The vmp bumps voltage to a constant 18v no matter the input voltage. Seems to be working so far and I still have DI/PI at 50/50 fuel delivery. Will be really nice if I don’t have to upgrade port injectors, no I’m curious haw far just the booster will go.

    So do fuel pumps go off voltage for commanded flow type deal? So it keeps voltage and flow higher?

    There is a commanded fuel flow/voltage table. Basically runs a little less voltage to pump when fuel flow demand is low. I upped that table so that it was 14v all the time but even with stock calibration with the booster the fuel pump would get 18v no matter what.
