I've been staying with V7.5, but I've looked into switching to V8 recently. You can copy your V7.5 maps to V8 pretty easily. In the V7.5 scan tool, go to your desired map, open its properties, then click the button labeled "Copy for V8."

Go to your V8 maps, open a map's properties by clicking the little arrow next to "Config" or pressing Shift+F8, then press the clipboard paste button in the top right corner.

Have you changed your injectors during your installation?

Hi.

Yes I changed my injectors. Also updated injector data. But might have done something wrong_ I think Nonnieselman is looking into that to verify my settings. I will try to copy settings from v7.5 to 8.. Or just use 7.5.
Worked on the car again today. Did not make any progress but verified map sensor and fuel pressure. Old MAP and old tune showed 99.7 to 100.3 kpa while the new MAP was stable at 99 key on engine off.. Not 100%, but should be close enough?
Bought a 6 bar pressure gauge, but could not find the right adapters to connect it to my fuel rail. So had to disconnect the line from regulator to fuel rail to messure out of the regulator. Goes straight to 56psi when i turn ignition on. Stays there until fuel pump stops and fals back to 0. That is like it should be? Have ordered a 0-100psi/0-5 v transduser to mount in the fuel rail so i can log pressure in the future.

For those that has not seen my logs and tune, my current problem is that i need values around 100 in the main ve map just to idle at lambda 0. When trying to drive the car the throttle stops working. I can probably increase the etc predicted airflow even more, but the map does not look plausible.
