Default Re: Lean Misfires at 2700-2800 rpm

[quote=keithmac]I think I`m going to try doing a 360 to 440 or 430 change in the Emanage, this`ll give me a slightly rich condition and then I`ll see how the ecu trims it out and what happens elsewhere as a result.

Are you using an emanage ultimate system with injector level control? If so, then you'd think the injector level control would prevent the misfiring problem (if it is caused by the ECU seeing too little load ), as the stock ECU should be at the correct point on the fuel map during cruise.
