Dyno work complete.

[comfysofa]

To anyone that may be logging in now and again, sorry I've not posted for a while.....anyway....as above I'm not going to say it's a world first but, I may be close...

Just collected it today from cjs tuning, Chris has had it for the last 4 days so I could be the guinea pig. He's effectively dumped the ecu, adjusted it and re flashed it back with all restrictions removed and given it a custom fuel mapping. I may not be able to post the graph from tablet, if not ill upload tomorrow....so, mods are full arrow race headers, v&h brawlers and a k&n air filter.

Bhp up by 10 torque up by about 5 ft lbs. The mods are as follows...

1. O2 sensor removed
2. Red line increased
3. Flapper valve removed
4. Fuel shut off corrected.

Also there were apparently some quite heavy restrictions on the fuel injectors on 1st 2nd and 3rd gear. Hopefully I'll be parroting this off correctly. ...."the secondary fuel injectors are not coming on until 7000 rpm,  in 6th the secondary injectors cut in the 3000rpm.  I've copied the mapping for 6th to 1st, 2nd and third". Essentially you'll be looking at quite an increase in power in the lower gears.... He wasnt wrong.... ****  me it goes now...!

With regards to the fuel shut off. Now this is fixed if means there is now no popping and banging on the fuel shut off plus the gesture of going from off to on from a fueling/throttle point of view is now greasy smooth....makes a big difference.

All in all absolutely brilliant. So, if you want yours mapped, give Chris a call at cjs tuning and get booked in. He will, do a mail in service for the mods, fuel shut off, O2 sensor etc etc but won't do a custom map unless he has the bike on his dyno as he doesn't want anything with his name against it being anything short of perfect with regards to fueling which I do totally agree with. If you do, then now he's learnt on mine he can map yours inside a day.

I'll throw up links and photos tomorrow cos I can't from my tablet!

Dyno result.

z1ooo getting caned on the dyno....

If my maths is correct, allowing for drive train loss in power this puts mine at 163bhp....just a tad more than an s1000r which is currently top of the crop....

WOW, very impressive indeed. Bet the bike is a dream to ride and it just shows it is really worth getting the bike set up correctly.

Your telling me!.....second day to work on it this morning....what Chris has done is transformed the bike on pretty well every level....ill try to list (not necessarily in order) what ive found...

1. Power, the graph shows all...loads more of it everwhere. This morning I went to work, which involves going over a few dual carriageways separated by roundabouts. Opened it up in first which took the front wheel up, dropped in 2nd for the gear change, up again, dropped into 3rd and then up again, all off the throttle, light steering in 4th and then through the rest.

2. With the above - its using definitely less fuel. I know how much it uses from day to day as I top up my tank most nights at home and have come to know how much goes in if I say gun it to work or drive slowly....Id guess im using about 20% less fuel.

3. The fuel cut off mod: as well as no popping and banging when you shut off the fuel on normal deceleration the bike doesn't feel like its being hooked up to a giant elastic band pulling you back....now, when the throttle is shut off it more..... "glides" to halt instead of being "pulled" to a halt.

4. Low speed driving through heavy traffic: The difference is amazing, much more control from the 30mph downward speed, easier for winding through heavy traffic at sometimes slower than walking speed.

5. Might be the placebo effect but it seems to be a tad quieter...

I couldn't recommend it enough. Even if you live to far away to do it in a day id say spend the night, get it done, and then laugh in your crash helmet all the way home....but get your bike set up first the way you want it....ie exhaust, air filter etc etc as if you change anything youll need to get it done again....I believe Chris is the only person in the UK to have done this.

Next stop is either rear shock or quickshifter - im thinking quickshifter as its cheaper.....and I can't wait for the pop between gear changes!

You are doing an excellent job with your bike, also a great job sharing your information. It will certainly make it easy for anyone thinking of doing any similar modifications, as you have done the ground work for them.

Well done and I will continue to follow your posts with interest.

Cheers! Just about to post another nugget now! I'm hoping as I said previously to get some more of the UK Z users to post here and liven it up!

Hi comfysofa would you say this is a better way to go than using a power commander with a custom map ?? At present I have on my gen3 a full Akro 4-2-2  k&n filter and pc v fitted but with a map that needs sorting as came off a mates bike was going to get it remapped over the winter along with some nice bolt on goodies rear sets carbon and the like 

[comfysofa]

Absolutely - nothing can beat a custom mapping. The power commander only inserts its mapping - nothing more. Access to the ECU gives more control. Moreso control over the stuff that the power commander cant get to like engine braking, fuel cut off, injector control, flapper valve motor control and Lambda sensors - usually the last 2 are disabled as the custom map is not interfered with then.

In fact Id read just recently that power commander looks like they've cottoned onto the fact that their add in boxes "aint cutting it" anymore and are bringing something to market to get a slice of the action - but what that is I don't know.

The only downside of a custom mapping is if you make changes to your engine setup then essentially your bike needs remapping....but not many people change their engine setup....having said that I went from a twin exit system to a single exit...while it feels just the same it could probably do with going back on the dyno if I was a bit ocd about it.

My advice would be to get your exhaust and air filter/airbox how you want it then take it to the dyno - obviously using someone that's capable of reflashing an ecu....

Just to reiterate - I think a you tuber called "ONE_BAD_Z" had ivans flash put on his which is a kind of hybrid powercommander/ecu reflash set up but said that he got more from the straight custom mapping - he put the dyno figures up to verify it.

Hope that helps.

PS if you sell the pcv itll probably pay for the custom mapping (or well onto the cost anyway) - oh - welcome to the forum.!
