ATV Fuel Injection Tuning With A PIM
by Nick Harris on Feb 24ATV fuel injection technology is constantly making significant strides in bringing proven performance into a more affordable price range. Fuel injection systems provide a dramatic performance improvement over natural induction and carburation based engines in that they are infinitely adjustable.
Perhaps the biggest advantage in using an ATV fuel injection system is the complete elimination of traditional jetting. Non fuel injected ATV engines need to adjust the jetting and needles with every performance upgrade or they risk catastrophic failure. In comparison an ATV fuel injection system not only eliminates that need to adjust jets the computer control unit can help keep an ATV engine safe in any running condition.
Instead of fumbling with jets it’s much easier to just plug in your laptop.
EFI management, or electronic fuel injection management, is proven ATV racing technology and a fuel injection PIM unit, or Peripheral Interface Unit, allows full control of your ATVs EFI management from your laptop computer. Yoshimura brought PIM units to market several years ago but their price has kept them out of most tool boxes.
Next month Yoshimura plans to launch version 2 of their proven PIM units and although still expensive with an MSRP in the $350.00 range I expect to see more of them sold to weekend warriors as time goes on and prices continue to fall.
The 2009 PIM 2 Features 1800 adjustment points for finite control as well as…
- An Easy to read screen
- Two maps with a handlebar switch available
- A USB cable port for easy laptop connection
- A plug and play wiring harness for ease in installation
- An instructional DVD to help you get the most out of your PIM
- A dyno tuning CLAT (Closed Loop Advanced Tuner) for performance shops
If you’d like to take your ATV from the dinosaur age and turn it into a contender, and you own one of the following ATVs you’re in luck, there is a PIM for you. (more models are being added constantly).
