So I have a B17a1 swapped eg running a p72 with an s300v2. It’s been running great up until recently. Once i make an adjustment to anything on the calibration, it’s 50/50 whether it’ll want to start or not. It cranks and idles for about a second before stalling and dying. When i hit new calibration and load the stock ecu map, it runs just fine, but any of my old calibrations won’t start. Could this be a hardware issue with the actual ecu or the actual sManager software?

Any help is greatly appreciated!!

If you make a change to the newly opened stock calibration , does it work?

Once it starts i can usually make some adjustments, but after a certain amount it wont starting, or if i upload while it’s running, it’ll just stall and die.

You shouldn't upload while it is running.

What change are you making when it dies, and how are you uploading the change?

Mainly just changing fuel table values, but sometimes i’ll change something as small as the shift light or rev limiter will cause it to not start

On the options menu, do you have realtime update checked?

It’s not turned on currently

Turn it on, then once you have uploaded you can make small changes without having go upload.
