View Full Version : Power Commander

I'm thinking of fitting a power commander to my Z750. Couple of things...
What kit do I need to buy ?
How do I fit it ?
I've videos on web site looks a specialist needs to fit it & map it.
Please advise
They will be bike specific models of the pc so you'll want the right one for sure, tho potentially can be some minor cross comparability - my falco has an rsv one - but works as the motor and ecu are the same. Fitting is easier than an alarm, bit of cable routing, a splice lead off the tps and unplug the leads to the injectors and couple in the pc loom. It's what you then do with it is the bigger issue - potentially they say the base map improves the bike but the bigger benefit is to fine tune fuelling and ignition timing if you can / want the extra on top. Mot done will finish this post when back at a pc...
.. so ideally once fitted you would look to get a custom map done to your bike somewhere with a dyno 250i - which will check and adjust air fuel ratio at varying throttle openings at 500rpm intervals...so afterwards the mixture is optimised across the board.
However if your bike is'nt modified / modified much you may not get much gains - ie the stock ecu map is optimised already, although there may be a flat spot for emissions. If you have changed the exhaust / induction much from stock then original settings may then move out from ideal.
Dynojet also hold a range of maps to load for each supported bike each with some variation of mods done, so you can play with maps available but I spend a good chunk of last year running rich on a map which was fuelling too much, knowing how rich or lean the bike runs without the kit is gonna be tricky.

Just buy a z1000 ;-) or an R6 we both know they are faster lol

the pre-2009 z1k's I tried were way slower than z750 with PCIII. too heavy. can't argue with the R6 tho!
MM - instructions come with the unit when you buy it. Very easy to fit, happy to help. We can sort that suspension of yours out while we're at it!! Also have a wander around zedoc.co.uk where there are loads of really helpful photo-by-photo guides and I'm pretty sure there will be a few for fitting PCs.

on the maps you can download from the PC website to get you started - just find the one that suits you closest - then get down to JHS to have it set up properly.
also you'll find others on zedoc will already have a map or two and will happily send it on to you.

Thanks guys, Bit more thought before I make the purchase.
What difference(s) will it make to the bike ?

Thanks guys, Bit more thought before I make the purchase. Bike runs rich & pops & crackles when I close the throttle.
surely the snap, crackle and pop on the over-run is just the air injection system.
Why not just blank it?
Easy enough................
Shame Bladerider's not around to explain Stu but he had one fitted by the boys at JHS last year and thought it was fab.
you boys and your toys! ::) ;) ;D

With mine (my old z750) it increased torque hugely throughout the rev range but it was really noticeable at the lower end. Felt like I'd immediately dropped a tooth or two from the sprocket. I was told much of it was a problem with losing the back pressure from the standard can - the engine went flat. One PCIII (as they were back then) and map later and it was a transformation. The maps are also completely adjustable to suit - you save the set up one so you always have that to go back to and then copy it as the starting point for a new map - if you like the sound of your bike farting through traffic (I quickly got embarrassed of that tbh! :-[) then you just adjust the fuel air ratio to suit. Many hours of fun in the garage with a laptop if you fancy that sort of thing!

Call James at JHS racing 0117 9868844. He fitted mine and did a custom map for it. Think it was about £380 including dyno time. The thing I noticed was the torque. My zx, a Fireblade and a tuono all rolled on in top gear at 50mph and I blew them away.
Haven't tried doing my own maps yet but sounds like fun.

Monste Man.... If you get any major info on these then i'd love to share the wealth of knowledge.
Im currently looking at having one of these fitted too atm... and at that stage of gathering info to decide whether it justifys the expense etc.
I got a few contacts in the world of bikeshops, parts and racing... so might askif theres any1 will to do us a deal on two or something once we're both sure we want one.
keep me posted dude,
Tom :)

Found a Power Commander ship from the US including shipping £198.00
I think I shall make the purchase just check with a UK supplier that its the same type
Power Commander V 17-016 Euro
www.morepoweracing.com
Quick question MM...
Why do you think you need a PC?
Also...I believe...that should you buy a PC from the US, it won't be covered by any warranty by DynoJet UK should anything go tits on it.

if you dont buy the PC from the dyno operator, they may not give such a good rate for setting a custom map on the rolling road....
you may end up spending as much on a US PC and dyno time and not have the warranty....
if youre going to have a map made on the rolling road, id do some induction mods first, then the custom map can be made to suit all of your mods...
as mentioned earlier, why not drop a tooth on the front sprocket...biggest performance gain youll get for approx £15.... :-)

Forget the PC and get an all singing all dancing Bazzazz instead. It's got more fueling options than PC, its also got quickshifter and traction control built in.
Bat Fastard has one on his GSXR1000 L0

another draw-back on buying from the US is it will almost certainly attract import VAT, so factor an extra 20% on the sterling value of it if you want the Post Office to release it to you!
dropping a tooth on the sprocket is a great mod on that bike, but it won't do anything for the fuel/air ratio - you'll still be farting up a storm with a breathy engine (don't know why I'm thinking of that old cadbury's caramel advert now!)

Hey sr, interesting bazzazz comment - hadn't heard of them before so thanks for the heads up for future reference. From a quick look though they seem to be 3x the price of a PC and not for a z750 (or z1k)?
Correct on the VAT - anything over £18 in value will now get it added plus you will have to make a trip to the post office to collect. I used to get away with it up to £100 but not anymore.

They were very good when they did the Sv. Improved it no end!

Gimme 20 quid and I will test the performance , am sure there are others here that will do it even cheaper.
lol @ performance testing.
£30 for James' dad to cane your bike down the road and back.
So....why the need for a PC MM? Is it because the bike is running a bit rich?

do you have a "capped take off point" in the downpipes for an oxygen sensor?....
if so you could strap a voltmeter to the clocks, wire in the PC and add a wide range sensor to the exhaust and map it yourself on the road under real conditions...
the fuelling creates a reading on the volt meter through the O2 sensor, and you can then use the buttons on the PC to alter the fuelling.
gissa shout next time youre in the pub, this way you could even fit a second hand PC and add a map thats quite close before adjusting it in the correct rev range/volt meter reading.....

To be honest, that's a lot of money just to cure a problem which isn't really a big 'un anyway. A new end can wouldn't have made that much of a difference. If it were a full system though a remap would be a must.
If the new can affected the power delivery with maybe a flat spot then I'd agree that a PC is necessary.
But it's your money of course. However, if it were me, I'd just wait till I spotted a bargain on ebay.

I can only say putting a free-er can (blue flame in my case) on my old z killed the engine completely until I had the pc installed. It wasn't just 'a' flat spot, it was right through the rev range. I couldn't believe the difference the can made either, but as soon as the pc was on, even with a standard map, it was significantly better than stock.
MM - waiting for ebay might be better idea anyway given the day's revelations! >:(
fitted one to my bike and it was like riding a new machine no flat spots and pulled like a train

Ok, i dunno about MM's setup.. but this is why i was looking at a pc personally..
I have already dropped one tooth at front, made a good difference and i wud recommend that to others...
I'm up two teeth on the back aswell.... Bike now rides Exactly how i want it to, the gearing suits my style of riding...and although acceleration is up, top end hasn't really been effected like all the horror stories you hear from people who don't know what they talking about.
I also have a full race system.. exhaust setup, which i wasn't sporting on sunday, but will have re-fitted it by the next time im out with you all.
I have also had a lil piston work done to the internals..
and Run a K&N air filter and some Velocity Stacks too..
Bike dosn't appear to be running lean, which is always the worse case, and dosn't appear to run that rich, maybe just a lil.... the flat spots arn't massively noticable tbh and it pulls quite hard.
But a friend of mine who knows alot about getting the most out of Gixxers, recommends a PC, to get the optimum setup out of my bike..
next on the list Bigger/better brake setup and try and loose a lil more weight. ;)
oooh also, theres a company in corsham area that sets up bike suspension if i remember rightly....
heard a few people who went their where saying their bikes rode Amazingly better after being set up especially for them and there body weight/build/ride style by this guy.
anyone know of the company and if he's still in buisness??
Before anyone points out the obvious... the Gixxer 750's arn't faster then my current setup and tweaked 750's arn't enough faster to warrant an upgrade....
and i don't want to move up to a thou, as i like the flickability of the 600cc and also, like seeing/feeling the positive feedback from setting the bike up well....
the thou's are amazing quick, and loads of torque etc.... but the 600 lets me get away with alot more....and is more forgiving when you push its limits.
Plus i love my ride style of high rev's and working the gearbox etc.
maybe once i been on jaydee's bike tho, i'll change my tune all together. :)
Tom ;)
Never a short post with you eh Tom ;)
Seems like you need a PC for sure. All those mods won't be reaching their potential peak setup on the standard mapping. I'm surprised you haven't had it done already tbh
Get yourself a PC and booked in for mapping.
Oh...and the suspension place in Corsham....it isn't in Corsham anymore>>>

Hahaha...
Well i got a fair bit to say fella...
mainly due to experience and the fact that i don't talk sh*t, i just say it and do it bud :)
Know what they say.... Talk like a women, Ride like a bloke! ;)
Besides... gives the fair weathers riders sumit to get their teeth into when its raining Again!!
(something England is known for! lol )
and it amuses the forum vultures usually.... But i can generally back it all up on the road or the track mate! ;)
I knew you would know who that suspension company was mate.... i shudda just pm'd you in the 1st place!
Ooh i hope they didnt move far, Corsham would of been nice and easy to get to :(

I don't even know what you were going on about there but if you follow the link it'll take you to the thread about MH Racing.

Haha..
dude, if its that easy to lose you in convo, i hope ya 'track' abilities are better! ;)
I tired the Link mate... but apparently i don't have access to that section of WB or something.
But i googled MH Racing and looks like they are near chippenham area.
I'm give them a call tommorrow and get myself booked in.
cheers, :)
