    Didn't know where to put this but since it could be a big deal I figured it was new thread worthy.

    Thoughts? Guesses?

    Shiv has mentioned REV 3 output to control a fuel pump. Probably a bigger intank unit being controlled by the PROcede or augmenting the factory LPFP.

    Apparently, it's standalone. So guessing no need for a PROcede. Pretty interested in this.

    According to Shiv, its PNP for anyone, does not require a PROcede. Like @jpsimon said though, we will know Friday or early next week if that still holds true.

    Does anybody have a picture of the factory pump? I'm curious if we can run a Bosch 044 fuel pump

    He said it was pretty inexpensive. I know inexpensive can be very relative to the person saying it.

    Are we guessing under $300, $200?

    That might give us an idea of what brand/style the lpfp may be.

    An inline booster pump probably makes the most sense. They are inexpensive and easy to control with a piggyback like the JB4 (or procede). He is already cutting the fuel lines for his flex fuel sensor so it might even be able to connect in the same spot.

    Doing some E85 logging with a cheap Walbro GSL392 inline is on my long to-do list. Routine business and the new G5 boost control scheme has kept me fairly busy the last couple of weeks. Click here to enlarge

    Really? I'm awd so my drivetrain loss is even worse and I dynoed about 410awhp with e50 and fbo. This was after a dme fuel flash and if anything my fuel trims are too rich. At higher rpms my afrs are in the 11s so I'm guessing I have a good amount of fueling left before I worry about running lean.

    Why is that Enrita? I'm running e60 right now (stock turbos for now but 440HP) and AFR are SOLID! Only issue is the LPFP fuel pressure dips some at onset of WOT. I'm looking for a LPFP solution so I can try 100% E85. I'm hoping to be running 100% e85 when I put my Vargas ST2s on. As of right now the BMS backend flash with the G5 is solid!

    That's fine. Issues will come up on larger than stock turbos and higher HP than 440. You need to be hitting north of about 490whp roughly to start seeing issues. We personally saw this on @themyst 's car running as low as E33, about 19-ish psi and aggressive timing while targeting mid to low 12 AFRs...car would start to lean out around 6k rpm to 13.5 at redline without meth...with a CM10 nozzle though he's got plenty of fuel and his short term rims go to negative 20s...his car is now consistently making about ~510-515whp according to vdyno it looks like

    They can hit 500rw now on E85 but I did have a boost-a-pump in place on the in tank pump. An inline pump will be a cheaper and better alternative.
