Powerchip Stage II
I spoke with Powerchip Australia and mentioned Stage II software as I'm going to an Akrapovic system soon.
The person I spoke with advised all that will be changed is basically the CEL codes that would normally be thrown... However I recall a thread (:edit - found it here) a while ago that mentioned either a lean or rich fuelling condition with a catless/high flow X-pipe setup that was resolved by Powerchip Stage II... Anybody with Powerchip Stage II care to comment? |

So when getting a tune, you can clear CEL and SES for good?

That was the indication I got - they advised the front O2 sensors (pre-cat) determine air/fuel ratios for fueling under closed loop operation, whilst the rear O2 sensors are used for monitoring emissions.
Seems like there is a switch or something in the EMS software that ignores or disables rear O2 sensors... |

Were they also able to get rid of the dip at low RPM's (that the Akrapovic exhaust created) with stage II or did they leave that one unresolved??

I thought the european cars - including Aus and NZ cars - will not suffer from the CEL issue encountered by US cars when used in conjucntion with a complete Akrapovic exhaust system.
I will never trust Powerchip because they can't support any of the claims they make. Whenever I have asked for hard facts to support their various claims they have backed off and never contacted me. If you're willing to standby your product you must be prepared to support it with hard facts. I think Powerchip works well on super/turbo charged cars like the Porsches and the BMW 335i. I have seen some amazing figures on the dyno with a Powerchip tuned 335i which almost matched the M3 for power. But with a NA engine I don't think they have the know-how to do what they claim. Play safe.

The issue for US models is even with O2 adapters a CEL is thrown with stock ECU. It's interesting that Powerchip seems to have not the best reputation in Australia - I got the product because being in New Zealand my options are limited and I didn't want a product that required me to ship my ECU off somewhere. Powerchip provided me with the reflashing equipment and I did it all myself. Butt dyno says it is a good product that matches its claims - however I'm getting new DCT software update next week and will do a dyno on new BMW software and then after with Powerchip Stage II... |
