TSP Injector Relocation Kit FAQs

 

What air screw settings should I use for my bike?


*R2 tune means any tune after R2 including R2. R2,R3,R4 etc. This code should be on the back of your ECU.

 

What colors are my wires?

Here is a quick diagram of the colors of the wires. Please ensure you double-check this as many installers have connected these incorrectly and had to chase where the error is coming from.

*Please note – Sometimes, the injector wires are reversed from factory. On a stock bike this won’t be too noticeable, but it definitely will make a difference with our tune. Following the above guide will insure you install it correctly.

 

Where do I mount the power valve breather?

We accidentally missed this on our instructions, but we mount it on the right hand side of the bike against the inner side of the frame where the pipe and muffler connect together. Ensure the hose is not touching the exhaust otherwise it will melt. The hose doesn’t produce vacuum and has been fitted standard like this on carb bikes for many years.

 

Can I revert my injectors back to the stock location after getting my ECU flashed with a TSP IRK tune?

Yes, although it is not optimal and won’t be as powerful/smooth as running the injectors in the updated location with the updated tune, you can safely move the injector back to the standard location with this new mapping.

 

How come both of my injectors are firing, I thought the one in the intake doesn’t fire unless under load?

When in colder situations, or when the bike is cold, both injectors will fire in the warming up process. Once up to temp, the intake injector should only fire under load. If this is not the case, please double check to ensure your injector wire colours are correct. Although you may have plugged the injector plug back into the same injector spot you pulled it from, sometimes from factory they can (rarely) be plugged around the opposite way. Ensure you check the colours of your injector plugs.

 

Do I need a TSP Billet head to run the Injector Relocation Kit?

No, but you will get a definitely benefit in added throttle smoothness with our head design.

 

I have one of your Power Kits with your TSP Power Kits tune, do I need an updated TSP IRK tune to run your IRK?

To receive the full benefit of the relocation we highly recommend update to our new TSP IRK tune. This new tune has new injection phasing for the new location, as well as a few other changes. You can safely run the injection relocation kit on your current power kit tune, but it will not be optimal and it will be much more beneficial to get the new TSP IRK tune to suit.

150TPI models and 250/300 2018-2019 Models MUST run our TSP IRK tune otherwise your bike will not run correctly. 150TPI’s have reversed phasing to other models, and the 2018-2019’s will run too lean.

 

Do I need an oil pump delete kit?

No, the kit will run perfectly without it. This being said, if you want to run pre-mix, you will need the TSP Oil Pump Delete Kit.

 

Can I complete remove my oil tank after fitting the oil pump delete kit?

Yes you can, but note that your oil level light will come on. Our resistor tricks the ECU into thinking that your oil pump is running, but it does not have control over the oil level light. Some customers remove the bulb from this, other’s just leave it lit up.

 

Can I run the oil pump delete kit with the injectors in the stock location?

No, you will starve the bottom end of your bike and damage your engine. You will need to use any type of injector relocation kit with this kit where the injectors are relocated out of the cylinder.

 

What fuel ratio do you recommend with pre-mix?

This is ultimately up to yourself, but we run our bikes at 50:1.
