@ossett2k2 no ive only got a cheap code reader atm so all ive done is clean the iacv out and delete the code .so ecu hasn't been reset yet .ive tried all the normal things like the pill and the bcs and ive cleaned that out too .all pipes go where thy should .ive even taken the pipe off the actuator and still hits and holds 0.5 bar .which would suggest limp home mode i would think .my afr readsings are spot on too .never had any probs like this before .god i miss evos hahaha .

The cable to read and reset the ECU is very cheap you will also be able to datalog so will have a better idea of whats going on.
If your'e not bothered about datalogging then i think you can buy for under £10 a bluetooth ecu reader which will you can link up to your smartphone or pc and will let you reset.

Also,not sure on this one as i have classics but i've heard people say disconnecting the battery and holding the brake pedal down for a bit will reset the newage ecu?

Iv'e never used one so can't say 100% but im pretty sure a simple vag com cable is all that's needed to datalog.(circa £15-£20)
Take a look around romraider,is a very helpful site and the software is on there for free download.

I don't believe any resetting can be done manually to the Denso ECU in Newage cars and as it's a fast learner there's no need anyway.
