Bump!!!!

Power Commander on stock bike????
Anyone??????

On a stock bike you shouldn't need to do anything other than the airbox mod. I cannot see how the PC could improve my bike at the moment. Now if I fit Arrow cans and a K&N then I might need one.
My CO setting are C1=12 and C2=14, but this works for my bike all TDMs are slightly different.

I'd like to see some dynos of a TDM with the airbox mod and the same with airbox mod reversed and a PC fitted.
Anyone got these?

Yeah... would love to try it, but there's no download link in your post...
Feel free to PM it to me

Thanks!

My 9er has standard exhausts and I fitted a PC 3 about 18 months ago and had it dynoed. I did the airbox mod when I first bought the bike which obviously makes a difference but the PC 3 makes an even bigger improvement to the smoothnes of the power delivery right from low down the rev range. The graph shows a nice linear curve to around 5800 rpm and then flattens off with a measured output at the rear wheel of 79 bhp. The PC certainly improves the ridability of the bike but the downside is that it is not so economical. Before fitting the PC I could get high 50's to the gallon without trying too hard but now its around the 50 mark and if I push it hard its into the 40's.

Same here, fitted PCIII only a short while back and certainly provides smoothest power delivery and issues around low rpm snatchiness disappear. Not dissing the airbox mod as this is a good no-cost improvement, but the PCIII completes the job.

Interestingly my bike was way too rich when dyno'd before the PCIII was fitted (11%), but now around desired 14% using standard map with few tweaks using the fuel mix buttons on the front, so I'm getting improved mpg not worse (high-50s from low 50s).

As I've got standard cans I've not paid out for a custom map, but may do in the future especially if tempted by new cans, also as I'm only at 73bhp.

I was told by the Dyno chappie NOT to touch the dash buttons once its been setup on the dyno - you'll just mess up th efine tuning done by the map.

Sorry Dandy I'd missed your reply when you made it.

I didn't have the PC set-up on a dyno (£180= tightarse) just loaded the standard map then had a simple £25 dyno run done to see the state of play. I'd had a free run done a few months before that'd shown up over-rich running, which prompted the PC purchase (EBay - £100).

So the front button were with guidance of the dyno techie to tweak low and high rpm fuelling, if the run had shown up it was "way out" I was planning on having the proper custom map done.

If I ever get after-market cans I'll stump up for the proper job, but overall the standard map was pretty close.

So what was the dyno chappies advice then?

So what was the dyno chappies advice then?

I'd installed the PC with a standard map, I have a K&N but otherwise stock, and I'd felt it was way better than before the PC (smoother & more throttle response).

The dyno run showed I was a still a little rich in lower range (up to 3k), pretty fine in the mid (3-6k) and a little lean in the high (6k+). So I knocked it down one mark in the low and up one in the high - then left well alone. Perhaps another run would've confirmed the exact adjustment but I asked the techie about using the buttons and he reckoned adjusting by one mark would work.

I know that to take full benefit of the PC you need a custom map. but I was taking the tightarse option to try to get close without spending £150 more, accepting that if I were to get an aftermarket can I'd then definately get the custom map done.

But I've been more than happy with what I have, certainly a significant improvement over stock, given how little I've had to spend out (£125 all-in).

£180, think I'd be a tight arse aswell.

I got 4 quotes, the two most recommended places were £180, while a couple of the others were £150. This is for 3-4 hours work, so I took a bit of a gamble (given I wasn't trying to adapt to a non-standard can) and just had a simple dyno run done (£25) to see were I was at with a standard map.

I had the earlier, pre-PC fitment, dyno chart so I knew how rich it had been running and I was fortunate that I'd got pretty close without the need for a custom map. Pretty sure that with an aftermarket can you need a custom map, though not sure if you have a map from another owner with the same set-up whether this'd be good enough.

Are you talking about the buttons on the P Commander? I've never used them.........

Yes, but as you said before if you've had a custom map done then you shouldn't really have any need to be messing with them.

If not, then they split the rev range into three bands (you can see what they are by using the software connected to a laptop) and you can "manually" adjust (richer/leaner) each of these bands, but clearly this isn't as sophisticated as true dyno custom set-up.

[AJ_Blizzard]

Doh!!! Sorry lads. Here it is. Just rename the extension back to .DJM. It would not let me upload as a DJM but TXT was ok.

Downloaded and renamed, but still no luck...
Perhaps you could zip it and try to upload it again...

[Sparra]

Hope this works. Sorry have not been around lately got made redundant and had career change with no access to computers. Still will not allow .DJM so just rename the extension from .txt to .djm.

Ok!
There it was

Thank you!

[AJ_Blizzard]

Many thanks to you AJ_Blizzard (and hallrob1) for sharing the resulting map. At least up to 5500 rpm in the posted picture

Me happy

You're welcome

And here's the missing part of the map:
