Exhaust valve not opening anymore after installing MHD(FIXED)

[WhiteNissan300zx]

I have a 2021 Supra and just did the bench unlock and then flashed the multimaps on MHD+ and sport mode won’t open the valves anymore. Anyone know why? On regular MHD it was working fine now it won’t anymore.

It’s a MHD setting. Hold the stock to get the CEL to flash, those are map switch options. Tap it again and it’s the exhaust flap settings. I think 0 or 1 is closed flap unless you’re in sport, one of the numbers keeps the flap closed always.
