a few weeks ago my car had the iacv problem with the engine light on .i got my code scanner on it and removed the engine light then cleaned the iacv and new gasket .thing is my car seems to be in a limp mode state would the ecu need resetting if the iacv and engine light appear .running 0.5 bar .not had the car long .any software downloads i can get on laptop and use my code reader wire to reset ecu .its mapped and was (supposed to e running 320 -330 but its never felt quick .

car is an 53 reg wrx .searched loads on here but nothing with a fix so looks like its time to go to a tuner .any recommendations near sheffield that arnt going to rape my wallet

 

Have you reset the ecu now then and it's still in limp?
Have a look over on romraider,im sure all the software you need will be on there.

 

@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?

 

so if i download romraider and buy the cable i will be able to datalog and reset ecu .any links for the cable .thanks for your help ossett2k2

 

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.

ill have a look now thanks loads

 

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.

I had a feeling the brake pedal trick was a load of bollox lol
