JMS fuelmax question

[BlackGT]

I am also having intermittent long start issues as well but I am running the Vortech BAP. Any updates on what might be causing this?

On the harness going to the pedal sensor... There is a ground and ground to enable. Do either of these get used and if yes where did you connect them to? Pictures would be greatly appreciated!

Also anyone use the 30 amp fuse? Sorry for all the questions but the instructions aren't clear for 2015

No need for the fuse on the 15, it is 30 amp from the factory.

Thanks. What about the ground and ground to enable at the gas pedal?

ground to enable means the fuelmax is just always on.
Enable to gas pedal is that harness that takes a voltage reading from your pedal and it will activate at a given pedal position.

OK so I have the pnp installed on the gas pedal sensor... So do I just not hook up those two grounds wires?

Yes. Do not hook those up.

Are all you guys running 22v or 18v on your FuelMax?

18 here. It's been raining here for 3 days but as soon as it stops I plan on adjusting it.

O.k. here are my settings.

Switch 1 - on (initially for setup)
Switch 2 - on (for 22V)
Switch 3 - on (for voltage ramp from the pedal input)
Switch 4 - off (you want this off cause it sets your overall ramp @ 0.8V with DS 5 off)
Switch 5 - on (This DS sets the point of where the voltage is 100% fueling to 3.2V)

then switch 1 off to save the programming. The LED should blink.

You can adjust the input trigger to be earlier with the first dial Pot. I have that set at 2.4V as instructed.

So in my setup the voltage starts to ramp up at 2.4 Volts and is at 100% (all 22Volts) at 3.2V (almost 3/4 pedal) all the way to 5V (WOT)

You can move your ramp around between the Pot being set at different initial trigger voltages and then the amount of voltage with the dip switches to get to the max voltage of 18V or 22V. You can do

Dip Switch = (DS) Pot = Potentiometer
\\\\\3\\4\\5\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
.4V On On Off Example (Pot set to 1.8V + the .4V DS = full Volts at 2.2V)
.8V On Off On Example (Pot set to 2.0V + the .8V DS = full Volts at 2.8V)
1.2V On On On Example (Pot set to 3.2V + the 1.2VDS = full Volts at 4.2V)


So you can also set for zero ramp so as soon as the Pot is met with right foot then the BAP comes on 100% (18-22V).

Kind of a neat tuning tool as you can bring your fueling in later or sooner.

22v due to E85.

Sorry for the thread bump but what setup should I be for the Whipple with their tune on 93?

 

[z06psi]

The settings I posted above.

Do I need 22v for 93?

No. You can run it if you want to but fuel pump life will be shortened. E85 requires almost 14-16% more volume then your normal E10 (93).
