Using a first-gen Apple iPhone, it immediately found the AEM wi-fi network and connected. Opening the iPhone's web browser, we punched in the provided IP address, and voilà! An AEM-branded screen came up with AFR and EGT displays. The moment of truth - it was time to start the car and see how well it would display the data. Up until now, everything was going as expected.
As the engine roared to life, the AEM display instantly showed an AFR signal in the mid-14s. Brilliant! Revving the motor, the AFR quickly richened up. It was safe to say that the display had no lag whatsoever and was extremely quick at displaying accurate data. A test drive further proved the point. It was spot on in its reaction and readings. Heck, even when we stood outside the car, accurate readings were still being displayed with no signs of lag.
AEM has a real winner on its hands with the X-WiFi wideband UEGO and EGT wireless gauge controller. It lives up to every bit of hype and we can't wait to see what's next with this technology. Right now, AFR and EGT are the only available display parameters, but we anticipate (and hope) AEM is working on adding more sensors - like boost, oil pressure, oil temperature and much more - to the mix.
