TSP TPI Injector Relocation Kit

TSP TPI Injector Relocation Kit – 150, 250, & 300cc TPI

The TSP Injector Relocation Kit (IRK) moves one injector behind the throttle body (TBI) and leaves one injector in the cylinder (TPI).  You will want to reflash your ECU  with the latest TSP tune designed specifically for the TSP IRK.  It is highly recommended to run this kit with your choice of a TSP head, as the entire kit was designed to work seamlessly together.  Riders will notice an increase in off idle throttle response, a much smoother and more linear power delivery, and more pull up top with increased over rev compared to the standard TSP Power Kit and a massive improvement over stock.

Pricing:

  • TSP TPI Injector Relocation Kit (IRK):  $180
  • New customer TSP ECU flash: $300
  • Current TSP customer ECU re-flash: $100 ($200 savings)

Description

TSP’s unique TPI Injector Relocation Kit (IRK) combines the best of TPI with the best of TBI in one package.

The TSP IRK kit moves one injector to the intake (TBI) and leaves one injector in the stock TPI location. Combined with the TSP  custom ECU mapping which is designed specifically for the TSP IRK, the power delivery is next level and allows us to deliver the best of both worlds… the smoothness on/off the throttle of the TPI combined with the mid range and top end power increase of the TBI setup. The TSP IRK kit allows you to run premix, or you can continue to run the stock oil pump. The kit comes with all the necessary hardware for a simple installation… including fuel hose, hose clamps, an injector blank (installed in the right side of the cylinder) and a 3D aluminum printed injector mount. You will need to disassemble the stock fuel line and utilize some of the existing components, however there is no modification required, so it can always be put back to stock if necessary.

It is strongly recommend to install this kit with a TSP ECU re-flash and TSP head to take full advantage of the relocation benefits. With your ECU, we have control over the injector timing & phasing, which will drastically improve the smoothness & reliability of your TPI bike. The fuel pooling in the video example cannot be changed unless we change the ECU mapping. We also have access to fuel, ignition and oil maps to make the bike much more responsive, smooth and predictable, while offering more power and reliability over stock.

For customers who have previously purchased a TPI power kit that want to purchase this injector relocation kit, we will be offering the ECU re-flash update at a significant discount to these returning customers.

If you choose to run premix, not required,  you will need a TSP Oil Pump Delete Kit plug and play loom available for purchase as a separate kit on our web site.

Please see the full video below on the benefits TSP IRK and why we have changed to this new design. It will have some technical detail including engine videos explaining what we can achieve and why we are doing it.
