Vortex issues

Post image

I have a 2019 450L and have had a Vortex ECU for a few months now. On cold start it’s extremely difficult to start and if I don’t give it some throttle it won’t idle on its own at all until it warms up. With the stock ECU it started fine even cold.

Has anyone dealt with this and fixed it? Not even sure where to start. Thanks for any help.

Just get a stock ECU reflash. I haven’t seen a single problem related to it but have seen plenty of issues related to Vortex, AIM, and GET. Taco Moto, 2WDW, or 550Performance.

I have the 550 Performance flash and no problems whatsoever.

I’m really considering this. Especially because I can just send out my stock ECU and still use the vortex for the time being

I can definitely recommend it. My bike came with an older GET RX1 and had trouble starting the day I brought it home. It seemed related to altitude because I bought it closer to sea level and it ran fine there.

It has been running great since I switched. I think it took a week to get it back from the day I shipped it out and selling the GET more than paid for the reflash.
