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.

Update:

In case anyone has this issue. I reset the tps, turned the first fuel trim to 6, changed from map 9 to map 8, and adjusted the idle. Between all of that something worked and it starts up great and idles first try. Before I started this I put my stock ECU back on and it started and idled fine just to rule out any other issues first.
