Tune review

[SS Overhaul]

Can someone take a look at this tune for me?

Truck is ideling nicely, seems to miss when I open up the throttle.

Have an EDL in tank pump, pressure is reading 25psi prior to the fuel rails.

I have an EDL pressure regulator after the rails and before the fuel return line, that doesnt seem to regulate anything.
:confused:

What kind of engine?
Do you have the camshaft specs?...specifically the intake duration at .050" lift?
25 psi fuel pressure is very low. Which regulator do you have?

It looks like you setup that calibration for the MAP-N tuning strategy but the shape of that particular fuel map looks like one of our Alpha-N base maps. It will work but will need quite a bit of tuning. The shape of an Alpha-N fuel table is usually quite different than a MAP-N fuel table on the same engine.

(Keeping in mind that my pressure gauge may not be working properly)

My intention was to tune with the MAP-N, should I start from scratch?

Take a look at the quick start guide again. If you want to tune MAP-N, you have to go through the wizard like you did but afterwards, load in one of our MAP-N base cals.
