12 valve owners have been asking for it for years, and Attitude Performance Products delivered it....on-the-fly adjustability of the fueling. That's right, the mechanically fueled trucks can now have some of the benefits that were only limited to trucks with electronically controlled injection pumps now! Think of it kind of like a for your 12 valve...weird, huh?
Attitude Performance Product's Attitude Adjuster gives you full control of your 12-valve Cummins or any other engine equipped with a P7100 injection pump (4cyl, 6cyl, 8cyl) from inside the cab.
With the turn of a knob, you have full adjustability from 0mm of rack travel to 21mm (the 21max travel requires rack cap). APP's in-cab control box gives you complete pump control with only one full revolution of the knob.All this is done while retaining the AFC housing (boost advance) which is crucial for drivability. With the finite adjustment of APP's Attitude Adjuster, you will be able to tune from optimum economy to max power without leaving your seat!
Because of its adjustability, the Attitude Adjuster will work on every P7100 injection pump with no modification required; it has application for improving the performance of trucks from stock to highly modified. The AA is flow-bench and dyno proven. The AA housing comes pre-machined for the shut-off solenoid bracket on 94-98 Dodge Rams.
The Attitude Adjuster is a drop-in part! It's a direct replacement of the cam plate and does not require removal of the injection pump.Installation is as simple as swapping a cam plate. Finally there's a way to control your fueling from the cab, and all done so by remaining 100% mechanical!
The following chart shows incremental Attitude Adjuster Set Points on the knob, with corresponding fuel flow in cc's per 1000 strokes. Flow results from a model 911 P7100 injection pump with model 191 delivery valves, 4000 RPM governor springs, and rack cap:
