EGA tune

I have been searching out some place to get my bike power tuned in 6 or so weeks, and got an interesting response from a dealer today. I wrote, wondering if they had a dyno to tune bikes on, and that I had a PC. He wrote back saying that they did not have a dyno, and usually tuned Power Commanders with their Exhaust Gas Analyzer. My question is, doesn't that just tune the machine under static conditions, not under load? How efficient is that? I presume they just rev the motor in neutral, and set the map accordingly. Doesn't sound very accurate.

Anyone with experience want to chime in?

I would think a proper tune would involve loading the engine...the HC and CO definitely change when under load versys (pun intended) no load conditions.

I would concour with you Red. I find it hard to believe that an EGA "test" would give you accurate results. Being in the Marine Industry, there are a myriad of test equipment available for diagnostics......but...nothing will give you the results in the shop that a true water test {under a load throughout the operating range, and the test equipment, along with technicians experience}, will. The load your engine has in neutral at 4000 rpm is drastically different than it would be under acceleration, as you point out. There could be a "hole" in the fuel / timing map in {one} of those two scenarios. I'm a firm believer that any motor needs to be tested under real-world conditions. You can also have the best test equipment in the world, but if the Tech doing the work can't interpret the data properly...well.....
