Accelerator Module V Power Commander

[ahg]

Hi Folks

I have a 2009 1200 with Keihan headers and aftermarket pipe. I changed from standard to get a little more umph, as I did on my old 1200.

I am now deciding between an accelerator module and a power commander 2 with custom mapping.

I know that there is a cost difference but it is not so large that this will dictate the choice.

I just want the best choice in terms of reliability and MPG.

Does anyone have experience of both options?

Cheers

30 pounds for accelerator versus 500+ pounds for PC and custom mapping?

I think a comparison between the two will be like trying to compare apples to pears - there is a long thread that discusses the merits of the Accelerator module in depth but you cannot expect to compare it to a product that costs 15x more. You get what you pay for

Twist the throttle harder, perhaps?

That is not as factitious an answer as it may appear. You can see several threads where bods admit that they have suddenly discovered the delights of doing it.... We went on one of the Moroccan Dashes with a perfectly nice chap who confessed that he had never before twisted the throttle all the way back. It's not uncommon. Some people believe that rev's cannot be good....... It won't break and it'll save you £500 which is a lot of petrol.....

As to the £30 gizzmo? I bet a pound to your penny, that many bods could ride as fast (whatever that means) without one as someone who has made the change....

bit out on pricing

You are a bit out on your prices Unkle Festa. Full PCII with mapping is £370 all in. Still a significant difference in price but not so much that I won't go for what will be the best solutuion for machine reliability and MPG.

When I had the non cat pipes fitted to the previous 1200 the difference was striking. The bike pulled much harder and at lower revs.. a gap opening up could be taken advantage of without dancing on the gear lever and inclines when fully loaded two up hardly made a difference...I am not concerned about going faster than 100mph but it is nice to have more torque for a more relaxed and satisfying ride.

PS Throttle stops are no strangers to me!

Nor - waxing lyrical, it seems

You may feel inclined to get the PowerCommander set up on a Dyno - which will bring your outlay to the £500-mark?

You could also consider a Techlusion Fuel Module (also marketed by Wunderlich in their own name - but has the price hoofed up)

The Techlusion module can only increase (not reduce) fueling at different rev-ranges, but as most modern engines run super-lean (and more so with a cat bypass and end can etc) -it could fit the bill.

Techlusion is sig cheaper than a PC - but you'd need to check online.

includes dyno too

Hello Blackal

The £370 includes dyno set up to get the custom mapping. I think that this is quite a good price and probably reflects the quiet January period. The possibility of a weak mixture due to the pipe changes is what is driving me to get one or the other of these devices as I understand that later 1200's are prone to even weaker running.

I know that if I shelled out for after market headers and end can then the only option I'd even be considering would be a PC and dyno setup given standard ultra lean fuelling setup.

Remember the Accelerator module only crudely, although effectively, enrich the fuel mixture when the ECU is in open loop mode, i.e. under acceleration. A dyno set PC will ensure much more refined and correct fueling at all times. And if you can get the PC and dyno setup for £370 you should be jumping at the opportunity.

Had my 08 GSA PC3 USB and custom map done a couple of months back very pleased with the results Good increase in torque and hp plus better fuel consumption to boot! but also knowing that the engine is running the correct air fuel ratio throughout the rev range cost £320 saved a little by getting the pc from the States You get what you pay for !

Be sure to notify your insurance company.

Interesting one that. Should we inform our insurance about fitting the Accelerator mod? It modifies the fuel mix but is not particularly a performance enhancer (no extra power etc.).

Any modification from standard requires us to inform our insurers, in case of possible claim voidance
However, after 30+ years biking and several accident theft claims. I’ve have never had my insurance void due to unstated mods.


£320 for a PC3+set-up is a damn good price. But I’ll stick to my £27 Acc/mod, it ticks all the boxes for me.

Full PCII with mapping is £370 all in. QUOTE]

Correct me if I’m wrong, but I thought only PC3 USB or PC5 were compatible with the 1200GS’s

 

[ahg]

PC for me I think

Thanks for the feedback guys - Surmanator's experience has confirmed what I hoped for - its a win win situation. I have read the quote again and it is a power commander 5 pcv not a 2 - can't read properly!

I will post an update after I get it fitted - if all this snow and ice ever goes away.

its the "in thing" at the mo,,,
when these were out a few years ago(,different name and shape but did the same thing) they were slated as no good,
it all depends who says they are good on here, plus i think, the 1200 owners can be "herded" more easily?..
does run a bit better with em though, (did a few years ago too though,,,)
snooty,,
you dont always get what you pay for, cos its dear, doesnt mean to say its better ,,, (look in the touratwat catalogue )

May be true - fashion has it's place everywhere. Having never had an 1150 I can't comment however it does seem a common complaint from 1200 owners (myself included) about the snatchy throttle at low speed/low revs. I'm buying an Accelerator just to get rid of or improve one of the few things I dislike about my bike. When I get round to fitting decatted headers to go with my Akra can I will be going the PC route. Probably.

I have no experience of the cheaper option, so really can't comment on that.

What I can say is that the Power Commander and dyno setup that I had done on my bike significantly improved throttle response and precision throughout the rev range and all but eliminated the previously very noticeable flat spot.

This is a bike with Remus headers and free flowing end can.

The PC didn't make any noticeable difference to outright performance higher in the rev range, as the full system has been on the bike from new. I think the dyno reported it as being a few ponies better than before, but the thing you notice from the seat is smoother fueling.

No doubt someone jumping from completely stock to a full system plus PC would notice a more significant power gain.

I would say that, if you are happy to pay for the Power Commander and the mapping, then that would be the way to go.
