Flash Tune Issues

[AndyST13]

Hi, I'm having issues with a flash tune. The car had been running on this (Collins) map fine for a couple of years but now it will rev to around 3.5k and then some kind of safety kicks in and the car cuts the throttle. Switching back to the stock map "fixes" it but I'm curious what has changed.

I'm hoping that someone that knows what they are looking at can check this log and see if there is anything obvious. Line 18 I go full throttle in 3rd gear from 30mph and within a couple of seconds it cuts the throttle. I see fuel rail pressure drops to 700psi by line 19 but I don't know if it is cause or effect.

Any help much appreciated.

I'm not familiar with Collins' tunes, but is it possible that you accidentally switched the tune into economy mode or something similar? I did that once (at the track, lol). Easy to do if you hit the Cancel/Resume button on the cruise control and then hit the up or down buttons -- this is an Accessport feature, so I'm I assume it would affect all tunes
