There is an expectation that when we are tuning the fuel table in an ECU, that each cylinder will respond the same and operate with the same lambda value. In reality though this is often far from the case, and machining tolerances, injector inconsistencies and poor flow distribution in the intake manifold can all add up to significant cylinder to cylinder fluctuations.

In this webinar we investigate individual cylinder tuning using our Toyota GT86 fitted with the Motec M150 ECU and an AEM 4 channel UEGO wideband unit to investigate just how much each cylinder can vary.
