Kev I plan to get to the Dyno earlier and give you a clear run with your projects. Mine is all standard and I want a quick baseline and a peek at the A/F ratios of the out of the box system. Just amateur curiosity.

No worries see you there, all fun & games. :D

You will need to block off your SAS pipes if you want a true A/F ratio, I will be bring 2 clamping tools to block off the SAS pipes from the outside, we can fit them on your bike if you want for the run, I will come a bit earlier around 830am encase you need to borrow them.

As I expected the 1290 runs to rich on our Ozzy fuels & we would pick up a few more HP by leaning it out.

Image

We did a shoot out between the Standard air filter against the DNA main air filter, no map change with standard exhaust & Can. RED run with DNA filter, BLUE run with STD filter.

A/F ratio

One thing I am happy about for us Ozzy boys is we can add some more air flow in/out & the A/F ratio will not be to lean, time to start to playing with the air box. :D

Thanks Kev, first step is the DNA filter... Looks to be running very rich based A/F chart.

The difference between my modified SMT 990 & my standard 1290 with a DNA filter, the 1290 just has more power every where, from 6000rpm the 1290 just takes off.

HP WOW

Image

Torque WOW again, measured on the same Dyno.

Impressive numbers for sure! Thanks for posting, and already showing how the engine is responding to initial mods.

Hey Kev,

What do you think will be optimal for OZ fuels and riding conditions and which way are you going to go with the bike?

I will defiantly go the filter with my slin-on with baffle removed for the moment.



Cheers

99% of the time the magic A/F ratio number is 13.2:1, we tested 2 X 1290's on the Dyno yesterday & they both were to rich everywhere running on Ozzy fuels.

I also tested my O2 controller which is working in controlling the A/F ratio in the closed loop mapping it just needs to richen up the A/F ratio a bit more, which I will test soon once I make some more adjustments to it & I have done my air box & pipe mods I will head back to the Dyno for some more testing, the measured closed A/F ratio on the Dyno under load was 14.7:1 & my controller corrected it to 14:1, I am looking for a target of 13.6:1.

would there be much difference between 95 and premium?


I'm running premium from BP and Caltex which is the same fuel because it comes from the same refinery in Brisbane.

Was 14:7/9 the result with the DNA filter Kev?

My bike had BP 95ron fuel in it for the Dyno, there is not much difference between the RON ratings.

The 14.7:1 is in the closed loop mapping for emission control when the bike is cruising & at small throttle openings, the figure was the same on both bikes with & without the DNA filter, the 14.7:1 is the jerking at small throttle openings we feel on the 1290's which is not bad by the way, but I know we can improve the ride by fooling the O2 sensor circuit to 13.6:1 which I target all my O2 controllers at.

Does that very wavy torque line on the 1290 mean the current mapping is in need of a lot of refinement? By comparison Kev's modified SMT is smoothly progressive.

Kev, hopefully a simple one for you.
Around the time of the first service, I intend to fit a slip on (probably Wings) and the DNA filter.
This time I'm going to make a serious effort to stop there with engine mods. Just want to improve airflow and get a nice exhaust note, and besides I've run out of money :(
Question: is there any point having the dealer block and disable the SAI as I will still be running a cat?
I will only get to the dealer once a year (900km round trip), so the 1000km service would be the time to do it if need be.
