power commander

[usv650]

i recently installed a powercommander on my 07 sv and i cant seem to find a good map for it all i have done is a scorpion high mount slip on and a k&n air filter.i gained alot of top end power with the tune i installed in it now.but it seems to have lost its low end toque. any ideas?

[hovis]

have you tried the website?

[usv650]

i downloaded the latest software update powercommander has to offer. but idk if anyone is running the same setup as me that would be great.

I had just the same problem, I could not get a map that was just right for my bike (basically, K + N filter, full Arrow system plus a little more messing) I have had to use the map that is just for Arrow system, I intend writing my own map based on the arrow map, I will adjust the fuelling in the direction I believe it has to go and then try it on a road ride (the best way to see if you like the way the engine performs), I had little or no help from forum even though I suspect there are lots of people out there (mini twins racers) with good maps for power commander.

i installed the map for a leovince fully exhaust it has no bottom end ill jus keep adjusting it.

Yeah, well, we're all ar$eholes. That would explain it.




BTW, No Power Commander here. When I wanted more power, I bought a more powerful bike.

Not all !

I cant recommend getting it setup properly enough - why spend all the money on exhaust/filter/PCIII and then scratch around in the dirt for a map? £150 tops will see a custom map for your bike and it will be better than any map you can find on the internet.

Mark Brewin at BSD did my map and it was worth every single penny - wish I had done it a year ago when I fitted the PCIII! :rolleyes:

i was quoted 150 to fit and set it up properly

how much freight do you think it will be to ship a bike to the uk form the us lol

Why dont you have a look at www.svrider.com (http://www.svrider.com) and see if you can find a somewhere a bit closer to you or maybe they can help you with a map on there. We're primarily a UK based site and svrider is a USA based site so you might find a bit more relevant info on there...

[usv650]

ok sounds like a good idea as well.

[ThEGr33k]

Get it on the Dyno and get the map set-up right :D May cost a fair amount though. :(

Not true! It depends how far it is out - I paid £95 for mine as it just needed fine tuning...
I was told that it would be no more than £145 inc VAT if it needed a full custom map...

is this with a power commander

or a remap of the standard ecu

[Skip]

That was a remap of the already fitted Power Commander

[silent11]

wouldnt it be cheaper to just remap the standard ecu to your spec

Pretty sure the levels you can go to with the PC are way above that of the standard ECU - also you can adjust the accelerator pump - really sharpened up the throttle repsonse on the Zed...

[john2811]

I'm thinking about buying a Power Commander with dyno custom map.

If I can wing it would anyone be interested in a group purchase either on Power Commanders or customer map or both?

Oh it would be Worcestershire/Gloucestershire borders so may be opportunity for a social too.
Register your interest. :-)

[northwind]

There's plenty of US folks who could do it for you ;) Honestly, I reckon a custom map is the only sensible way to go. But tbh you're not going to be far off stock mapping with just a slipon and filter. I hate to say it but the viable options are either a) tune it properly, ie full sytem etc, or b) don't **** with it. Fitting a PC for just a slipon and filter is not a good return on your investment- it won't give much results at all.

Incidentally, the best way to make a bike feel powerful is to lean out the midrange so that you lose power there- it makes the pickup to peak feel far more impressive :D Even if you're actually making no more power. We feel contrasts not absolutes.

Isn't an accelerator pump what they put on old slide/butterfly carbs? :-P

You might be able to adjust such things as STV curve (like the slide hole mod on a carbed bike...) and ignition curves and possibly fuel pressure but that depends heavily on the actual setup of the bike.

A PC is very much more adjustable than any standard ECU except possibly for the triumph's sagem system which is fully adjustable by anyone with a cable for it... The question is, on a lightly tuned roadbike, why do you need the mega-adjustability of a power commander?

A PC for a slip-on and a filter is a bit of an over kill, the standard ECU can compensate for these and if not for a small sum can be remapped just slightly to suit.

The standard ECU has a larger range of adjustment in it than what the SV's engine can offer in tuning ability.

You don't, and even with a well tuned SV race bike you don't as the ECU is more adjustable than people think.

[northwind]

The standard ECU doesn't adjust for it as it as no meaningful feedback, just MAF, no lambda (except for the latest ones that is)

[usv650]

with a slip on and a filter the bike ran very lean,i know lean is fast but i just didnt want to run that lean.im going to go have it tuned this weekend or the next to get all the fine adjustments done.

K7 has a Lamba doesn't it???

The standard ECU is more than enough for any state of SV, its easily remapped by somebody with the right equipment and knowledge.

[northwind]

I thought we were talking generally rather than about this one guy :) You're right though, the K7 has the lambda sensor. Don't know what its limits are though, whether it's constantly closed loop or more restricted like the old GSXR stuff was. Nobody seems to know so far.

Agreed with the ECU, if you can find someone competent to reflash it that makes most sense.

Sorry for the confusement, yes I was talking to this one guy ('usv650') with a SV650 K7. The ECU will compensate to a small degree so if you're fitting just a slip on it will compensate to suit. As for the early Pointy's with no Lamba sensor then no it will not compensate and a remap is in order!
