So what is this thing, and what does it do? As we all know, your air and fuel ratio are a great measure of  how efficient your tune is through out the RPM range. It is important to monitor while tuning, and under certain circumstances it is advantageous to monitor during vehicle operation. AEM has created what is essentially a wide band sensor perfect for tuning without the need of a gauge. How does it work if there are no gauges? The AEM Inline Wideband UEGO Controller has outputs for datacontrollers and pretty much every engine management system currently available. The controller use a Bosch sensor accurate to 0.1 AFR, and reads Gasoline, E85, Ethanol, and Methanol.

As most tuners know, in interference motors timing belts/timing chains hold the fate of your tune and motor’s well being within their grasp. Over time during normal operation factory chains are known to stretch modifying a motor’s timing . This issue is greatly exacerbated with the use of aftermarket camshafts and aggressive tunes. Several timing chain tensioners have been released to help maintain the slack of the chain. Toda has increased reliability even further with the introduction of their heavy duty timing chains. The chain has been engineer to “reduce chain stretching by as much as 35%”.

If you are v8 R8 owner, currently you maybe weighing your options. Luckily, German tuner MFK Autosports has recently become another option for those looking for modifications. Currently, they are providing an ECU reflash that raises the horsepower output 30HP to a round 450HP. MFK Autosports has also thrown another exhaust option into the ring with the release of their “flap-controlled sport exhaust system”; from the naming we assume that at upper RPM range the driver will be treated to a symphony of V8 goodness.
