Frequently Asked Questions


I plugged my ECU in and the bike won’t idle/has too high of an idle. What do I do?

Make sure your idle is set where you feel comfortable with it, then set the TPS. You may have to go back and forth with these steps until you find a happy medium. It is also very important to make sure that your throttle cable is not too tight and that there is enough slack for the throttle to fully close. You can adjust the tension with the two plastic pieces on your throttle cable near the bars.

What does “-1, -2 and -3 degree ing” mean on my map sheet?

The minus degrees indicate the ignition advance. This will give you less of a hit on the throttle and lengthen the gears. If you ever experience detonation, going to a minus degree ignition advance will help the engine run cooler and prevent detonation.

What are the “test maps” on my map sheet?

These are a variety of ignition curves that we have tested trackside with customers that offer different feelings. We have had great feedback with these maps.

What are the two cables coming from the ECU?

One cable is used for mapping and the other is an options port. This can be used for a second injector, map switch, quick shifter, etc

I have a Kawasakii / Suzuki and don't know what color coupler to use

The vortex ECU does not use any couplers to change the mapping. You can leave whatever coupler is currently on the motorcycle it wont effect any running conditions.

**In most cases, you can go between VP T4 and high octane pump gas. If using a more powerful fuel like VP Pro 6, it is common to add one click (2.5% more fuel) on the LO, MID and HI.

**We recommend that you spend time riding and testing the different maps and get a feel for them to better understand what each map does. It is helpful to take notes on your map sheet when testing out the maps.

What's the process of tuning an ECU?

How long does it take to get my ECU?

Upon receipt of your stock ECU or Vortex order, it typically takes 7 to 10 business days to complete the mapping process and have it shipped out to you.
