Surging Tsunami

[Cask23]

Well, on to an old story, or so I gather. Just got my R1150RT (2002) ... put the Staintune exhaust and the fancy software (Rhinewest Performance) to assist it. Got immediate extra pop out of the engine, but surge is as bad as ever. Thinking about using a Techlusion R259 - Q: General reactions/experiences? Q: Using it with the Staintune and Rhinewest software? Q: What is the significance of the 'check your O2 plug' reference in ordering an R259?

Unfortunatley, The fine people at techlusion will not recomend using any type of modification ( ie , rhinewest) to the fuel system, along with their product. I went thorugh this scenario last year, and fortunatley called RhineWest prior to purchasing, to see if their product would cure surging. They said, with confidence...NO. I have only the techlusion and a Sebring/Supertrapp can and am very happy with the results.

sorry

Try a different brand of fuel.
In my bike, gas from Shell creates a Tsunami surging.
with Chevron no surging whatsoever!

my surging comes and goes, and actually got worse after the 12K mi. service, even though everything else ran better.

go figure.

The only thing that has affected the surging in my `03 has been pulling the CCP module, and that doesn't cure it.

I thought the 2-spark fixed all surging.

Here is where I am at. Rhinewest has no idea how the R259 will work with its software. Techlusion has no idea how its R259 will work with the Rhinewest software. I have a bike tech at Adventure-Motorcycle.com who thinks that the R259 is so adjustable that it is well worth the go. So, in for a dime in for a dollar. Will get one and give it a roll. Stay tuned. ~ Cask23

I like what the R259 did for 04 R....has more or less cured my slight surging...and I'm still tweaking.

Goto http://www.bmwsporttouring.com or

and search for Techlusion on the forums....lots of good info.

I can't answer your question directly but I can tell you there is quite a bit to be gained with an adjustable ecu and dyno work. I've been working with an aftermarket ecu ('98 R11R) since about March of this year. In August I tuned the ecu on a dyno for the high load operation. I was pretty sure after that that the bike felt more powerful under most all cases. Today I had the occasion to re-connect the factory ecu and I believe it confirmed my feelings. While the factory ecu does very well in many areas (surging excluded) it is almost certainly more lean than it needs to be everywhere. That is what the dyno work resolved and why it feels better now on the new ecu.

For someone who can afford about $600 the new wideband power commander and dyno work may be the way to go. If you can't justify that much $$ but are the do-it-yourselfer and are willing to put in quite a bit of sweat equity you may want to go the route I went, check out http://www.msefi.com. The third choice is to go with the Techlusion, but throw in some dyno work at a shop with experience with the Techlusion.

I've got a ways to go before I'm totally content (likely never happen!) but I can see that this engine is crying out for a little more fuel.
