The TFI will increase your machine's overall horsepower and improve its throttle response to get the best performance out of all your modifications. Horsepower and torque gains are different for all the applications, but in general most can achieve a 10% gain in performance with a stage 1 upgrade. Stage 1 refers to adding an after-market exhaust, air intake, and EFI controller.
- MECHANICAL INTERFACE
For anyone who prefers a mechanical adjustment, the TFI has 4 potentiometers which adjust with a small flat-head screwdriver. The settings are given as wall clock positions and each pot offers extreme fine tuning since every small turn affects the fueling output.
- NO CPU NEEDED
This EFI controller is one of the only ones on the market which allows a large range of adjustability without the use of a computer.
We like to use the term 'on-the-fly' tuning. You can literally drive the vehicle, make setting adjustments, and instantaneously feel the results. Obviously for safety purposes we recommend you pull over to the side before making adjustments. Some after-market EFI
controllers like to claim 'on-the-fly' tuning which to them means toggling only between a couple preset maps. The TFI controller has the adjustability built into the unit without the need for a computer program to reprogram the unit. The fuel ranges within the controller are restricted based on the application, but most users do not require altering these ranges. Why deal with the complexity? It's an Electronic Jet Kit to make fuel injection tuning easy, simple, and fast so you can enjoy more time riding.
- NO DYNO REQUIRED
You do not have to be a professional mechanic or tuner and have access to a dynamometer in order to tune your vehicle with the EFI controller. Knowledge and good equipment obviously are a huge plus, but you can do just as good a job and sometimes better by tuning in real world riding situations. The controller allows this by breaking down a drive cycle into very understandable zones to make adjustments. Most controllers have the basic Idle/Cruise, Acceleration, and Full Throttle zones to adjust. Every rider can understand this terminology. The greatest advantage about tuning your vehicle yourself is your ride will be custom set up to your driving style.
- USES UNIQUE LOAD BASED TECHNOLOGY
The controller uses Load Based Technology which sets it apart from most of the competition. Most EFI controllers use what is called
'Alpha-N' Tuning Technology. Alpha-N tuning is associated with just using Throttle Position (TPS) and RPM as the factors to make tuning
adjustments. Load Based Technology differs by using Rate, TPS and RPM as the key factors for adjustment. Load Based tuning allows a user to
tune their vehicle for every gear and for all riding conditions. Load can easily be explained by stating that riding up a hill puts more "load"
on the vehicle than driving on a flat road, but yet the same TPS and RPM can be achieved in both circumstances.
- OFFERS FULL RANGE TUNABILITY
The controller is sold as an Electronic Jet Kit. Like carburetor jet kits of the past the controller offers a range of adjustability to tune
your vehicle. Instead of physical jets and needles the controller has this adjustability built into the unit and can quickly be adjusted
while riding the vehicle. Essentially with all EFI vehicles software has replaced some hardware. The controller can be installed and set to
actually allow the user to still run a stock configuration, but allows the user to ADD fuel within easy to understand tuning zones.
- DOES NOT INTERFERE WITH STOCK ECU OPERATION
This is a very common feature of all after market EFI controllers, but needs to be stated to reassure all end users. The controller does not trip any engine codes or affect the ECU operation in any way.
The hardware components within the controller are covered with a substance to make the controller water-resistant. The controller is
still an electrical device and without this coating would short-circuit when in contact with water based substances. The controller is NOT 100% water proof, but will continue to function properly through rainstorms, snow, washing your vehicle, etc.
- 2-YEAR WARRANTY
The controllers come with a two (2) year warranty from date of purchase against original defects in materials and workmanship. Should the controller fail to perform then the manufacturer will repair or replace the unit to the original retail purchaser at no charge except for shipping charges back to the manufacturer. Proof of purchase may be required.
NOTE: DO NOT cut any wires or apply dielectric grease to the terminals inside any connectors. Doing so will automatically void the warranty on your TFI controller.
The controller does NOT void any OEM vehicle warranty. A common mispractice of dealers is to tell customers certain products will void their newer vehicle's warranty. The Magnuson-Moss Warranty Act protects consumers from this practice.
