Well, currently, because I've got an autotune with my PC5 on my bike, I really needed a switch to be able to switch between map and learn mode.

Especially if I'd had it in learn mode and been out for a ride, if I turn the ignition off, the map trims the Autotune had made were all lost!

However, by having a switch somewhere accesible on the bike I can switch between the 2 on the fly AND when the bike is in learn mode, I can save the trims to the base map by turning it off rather than losing the trims everytime.

Sooo... I got 1 of the little ABS boxes I bought from RS for about �1, a switch I just happened to find laying around and some -VERY- special stainless steel braided fibre coated 2 core wire that was going to go to scrap and made up a nice little box switch...


Just need somewhere to mount it now...

Tadaa... done it!

First thing this morning



Looks fairly suiting I think, and the stainless braided wire looks ace too.

nice one Daz....i don't fully understand the autotune, but it looks the biz mate!! nicely thought out.....

i hope this is even more significant to your recent testing!!!

Nice work mate, at least you can now switch maps.

I find it handy being able to switch between fuel maps while riding, mine can store 5 different maps at one time.

Auto tune allows the rider to build their own fuel maps automatically, so no dyno time needed.

Just had a shufty on the Dynojet site...it is an incredible bit of kit!! Surely a must-have for Kev ???? Mind you, you already have that Wideband part of it. An initial big outlay, but would save you alot of time too ( i've noticed how well mapped your maps are Kev!).

Now, i know we are not talking R1 performance on this site, but, I wonder if there is ANY "ram air" effect on a stage 3 DNA Airbox? This bit of kit would show it wouldn't it?

Kev doesn't need the autotune because he's got the Wideband commander.

It's basically an autotune with bells and whistles



And no, there wouldn't be any Ram Air effect with the Stage 3.
Bikes with Ram air such as old FZR's and some ZX's I believe, work by having a couple of air ducts that run from the airbox on the backside of the engine, under the fuel tank to the front cowling hidden behind mesh.

The idea is that as the bike speeds up, the air is forced through ducts on the front of the bikes causing a sort of 'turbo' effect.

We are talking here though of quite high speeds to see any real kind of pressure difference or forced induction effect on the bike and for bikes used on the road is more of a gimmick because you'll never reach the speeds (legaly) on the road to be able to use it.

Well, basically, the autotune uses a wideband O2 sensor rather than a narrowband O2 sensor like what the bike comes with.

It uses the sensor to detect the AFR thats being produced and then directly taps into the PCV's trim table to produce fuel adjustments depending on the RPM, throttle position etc.

Then, you can go into the PCV software and accept the trim tables manually which will add them to the base map which I've got to admit, is a pain in the bloody ars3!

If you don't accept the trims, the base map will never be changed and so the new map wont be applied.


What the switch does, by having it turned on, the autotune is in learn mode and making adjustments in the trim table and I believe is applying them to the running of the bike. When you switch it off, it then applies this trims to the base map saving you from having to hook up a laptop to accept them.

Thats my understanding anyway.
