can someone rattle off a few causes of fuel cut so i can double check things.

would speedo cable not being plugged in cause it

 

Speedo cable not plugged in would limit your car to 4000-4500 rpm and 0.5bar boost.
I found the cold weather would cause overboost when giving it the beans through the gears.

 

ok think that may explain why it was cutting out at 4k revs

but it does hit fuel cut some days and not others

i will refit this scoobyecu i bought which raised fuel cut and see how i get on now i've plugged my speedo back in

 

yep really weird it never happened when i thought it would.

 

cant believe i forgot to plug my speedo back in

and i thought it was a dodgy ecu

oh well i'll give it a try 2moro lunch time
