Product Description

Tune Your Fox!
The P.M.S. goes far beyond the capabilities of a performance "chip" or "flash tuner", offering a broad selection of adjustments and tuning. Now you can take advantage of aftermarket performance components while still using the stock engine control computer! Step up to the P.M.S. and move into tomorrow’s world.

*Global fuel adjustments, which means you can offset the mass air for different sized injectors.
*Two step rev-limiter.
*Air charge temp and Water temp fuel and timing adjustments can now be made from -40° to +250°
*Two programmable RPM/Throttle output accessory control switches.
*TPS volts are now adjustable: What this means if you want 1.05 to be idle you put that in. The same with W.O.T. - you tell the PMS what volts.
*Tunable Nitrous Oxide Adjustment Table.
*Easier to use controller with adjustments down to 500 rpm increments starting at 2000 rpm.
*Tunable Turbo or Supercharger timing and fuel adjustment up to 30lb of boost.
*Single data display screens let you monitor spark timing, injector function, oxygen sensor, water temp, air charge temp., mass air voltage and manifold pressure/vacuum.
*Start fuel setting, which controls the injector when the starter is turning the motor over. This gets rid of the hard starting with 42 lb. injector or bigger.
*Air Fuel Mixture fully adjustable.
*Purple anodized, finned aluminum case resists corrosion, dirt and moisture.
*Idle Mixture and Timing fully adjustable.
*"Plug in and Run" installation requires no programming - Just start it up and go!
*Total spark and rate of advance fully adjustable
*Stand Alone turn on is now adjustable:The stand alone is set up to turn on at 3500 rpm, which can be adjusted from 2000 rpm to 5600 rpm. The factory EEC has no control in standalone model. This gives us even better fuel and timing control and now the Rev limiter can be moved to a high as 9900 rpm with a faster processor.
*Increased RAM, EPROM, and EEPROM Internal Memory Capacity!
*Easy "User Friendly" operation - detailed owner’s manual explains all functions.
*Series 4 with individual cylinder timing and fuel control.

Using this on 347. Smoothed the idle out pretty well. Currently working on the Part throttle and wide open fuel trims, Recommend use with a wide band. MAKE SMALL ADJUSTMENTS.

Yes, I would recommend this item to a friend!
