New ECM and my PCIII?

So as many did, I installed a PCIII on my DL1000 K5 when I had no help from the dealer. As we all know it works great and took care of the "sputter, cough, stall problems. Now with news of a fix for the ECM Im wondering if it is worth getting it done. Does anyone know what benifit I would get from unpluging and having the dealer fix the current ECM, and then reinstalling the PCIII? Id like to do it just for the oppertunity to give my dealer some shit for all the hassels last summer! Being told over and over that nothing was wrong and it was the way "I" was riding the bike really pissed me off.

Mine gets the transplant surgery on Wednesday. New PCM came from Japan. I ordered a PCIII anyway so I can adjust things, if needed, when I eventually make exhaust changes down the road.

I'd do it just because it's available even if my bike hadn't developed the symptoms just because of re-sale concerns.

The MAP in the PC-III will not "fit" the new ECM since the base map has changed. If they added fuel at 3000 RPM at 5% TPS than that cell will have to much fuel now as an example.

If you paid for a custom map the new ECM will need a new custom map and that is $.

But if you just down loaded a map ... or fiddled till it felt right, you can do it again. There will have to be a new PC map to down load to match up with the NEW ECM. I doubt they will have one available for quite some time for the 06. E-mail PC maybe they will work on it soon.

But when PC comes out with an 06 map than since you have an 06 in your 05 use the 06 map.

I don't know how much the new 06 ECM will give you over an 05 with a good PC-III map. Unless they changed the timing to any degree I would say no. However if they did and got a better match of timing and fuel at the 2000-3500 RPM range it MAY be worth getting the new ECM.

Since I do not have a PC-III on my DL1000 I will try for the new ECM. Then having the best base map to begin with will add a Tika or Yosh tweak to any areas that are to lean. My bet the 06 map will be just fine.

But if the 06 runs w/o and problems and gets me 45-48 MPG vs 42 and less, I will be most pleased. Is suspect it will yield better MPG than I am getting now. ? is .. is the 06 really the same as a 05 + a 1.5% Yosh at idle? and no timing changes? If so ... and you have made that change why waste your time.

Some people claim here they are getting 48 MPG with an 05 ECM and a slight Yosh tweak. For them I see no reason if they are happy to go through the trouble.

Unless we get some ECM geek to look at the 2 different programs and tell us what's changed I highly doubt we will know what parameters the 06 ECM has changed.

A stock 06 map vs a Custom map with an 06 will probably not have the same HP, but HP comes at a cost. Is 2-4 HP worth 3 MPG? Is 10 HP worth 5 MPG? It's up to you to ... My $.02 is if it runs good with just the stock 06 ECM, sell the PC-III to some guy who wants HP at any cost and use the $ for crash bars.

I feel the PC-III makes a big difference and is a good thing if you change pipes, intake etc. But for a stock bike if it runs correctly no real need.

I put tons of $ into my Le Mans. PC-III, pipe, cross over, intake, custom advanced map. How much different does it run now and at what cost.

I lost some low end torque. Lost 3 MPG and gained what... 6 HP maybe 10? I never did pay to Dyno it stock. It runs different .. The HP has moved up, and is not as low RPM friendly. Stock a roll on would lift the front end. Not now. But my 30 to 90 MPH times are less. Top end is smooth at 120-135 With better roll on at 90+

Realistically where can I drive like that? MOST of the time for most of my driving, a stock set of cans and stock map would yield better low to mid RPM personality let alone a little more power at low to mid TPS settings.

The changes are noticeable at over 3K rpm and 50% and over TPS. Then it comes to life. Unfortunately that is not anything I can really do at the posted speed limits.

This is why I got the DL1000. I wanted a fun bike at normal to a little over normal driving parameters. I did not buy the DL1000 for performance! It has plenty stock.

If I want to thrash a bike around I will take the Le Mans. If I want comfort fun and some economy I will take the DL1000.

If I want sedate retro bike fun my Cal-II fits the bill. Good power excellent torque, wonderful sound, and 45 MPG with carbs. (@580 lbs!)

After driving the V-Strom the Le Mans feels like a 500 lb 100 hp skate board. :shock:

Thanks for the imput John. Its pretty much what I thought. As far as MPG, I dont get near what some are claiming on here and a couple other sites I frequent. Im think I may disconnect the PCIII and get the new ECM, see for myself. Mothball the PCIII and wait for an updated program if need be. After riding last summer and having a couple of close calls as far as heafty tickets are concerned, the bike is plenty fast stock. Fortunatly my Staintunes are fine with the stock set-up anyhow.
