Hi PH. Sorry to see that you still have a problem but lets try and pin this one down.
First. Dont worry about the 4K flat spot, power in traffic, the fuel you use and stick with the idle problem to start with. Work on the other stuff later.
Second. Are you saying that if you do a TPS reset before each ride the idle is ok. Is it ok all the time IE Re starts, etc.
Third. From what I hear a lot of the 08 plus bikes have problems. The thing to do is cut out any possible probs you can. Which you have made a start doing. One thing, and costs nowt, is to run a new wire from the battery Neg to the point at which the loom Neg mounts to the frame. The reason for doing it is it makes sure you have a 100% good Earth for the ECM.
Hi Mark!
Well what I have found was that starting the bike up from cold usually resulted in the bike stalling just as it starts up recently! I havn't had enough time to fully test this procedure but last 3/4 times of doing a TPS reset first thing in the morning resulted in 100% perfect idle. Now my idle problems have always been after a short stops but sometimes I had poor idle from cold. whether or not it has been because of the night before or because of the last ride before I don't know? Havn't had poor hot idle since either but it's early days? Once I've done a morning TPS before a ride I havn't needed to do it again on that journey..........................yet! Problem is it's not just one problem, it's intermittent with variations so it's hard to put the fault in a single box.
HD have just told me that they've found the 4K flat spot and want to investigate tomorrow - so no bike tonight!! Although they did say that the breather mod was effecting their readings. I forgot about the breather mod which means my bike is not 100% std after all
Yes I will have a look at adding a new wire from Battery to L/H earth point.
