Kev, you have email...

and to further on from what I've mailed you, I've just found something even more interesting, but I'll let you read what I've sent you already first.

I will try to get my internet connection on the laptop, and will email map to you.......grrr....i hate computers.

I suspect the initial runs he did, with the DNA Map Open akros, the probe wasn't in properly, and then I think he re-adjusted it.........I would like to know other AF readings of the DNA 660 Open Ackros map

map sent Kev.....best you read the other emails first....check that it is not the DNA 660 "Open Acros" map,it should be a modified version of it, just havent retitled it.. its all new to me!
I also sent you my standard bike AF's, from my first dyno.....not sure if this is a PC111 Standard map or not, I bought it off Simon, and I think he may have pre-loaded a map on it. I had fitted and connected the PC111 on my bike for this first "Standard" dyno,, but hadn't linked it to a computer......

Are you able to get the guys to email you all your dyno runs, then forward them on to me?

Yes I will forward them on, I asked them to do it, just hasn't arrived yet.......

Well, glad its all running well! I know for sure that mine runs a hell of a lot better and thats with just the stage 2, been meaning to get the stage 1 but want to see what my DIY Stage 3 ends up like. And im currently in the process at work of making up a map switch to mount on my handlebars to be able to switch my autotune from Map and Learn mode.
1 because its something to do in 'free time' at work
2 because I can
3 because I can make it out of shiny stainless
4 because It'd be nice to have something custom built
5 because I'm too tight to buy one

:eusa_dance:

But Kudos to ya mate for getting it all set up!

Hi again Daz.....I don't think this is the optimum setting for the bike...... when looked into it, I think the AF Readings and Mapping don't make any sense..... but yes it goes very well!!

I am going to get them to do another AF check.........

Agree the A/F ratios do not make sense, I am sure the dyno tuner would have tuned for max HP & Torque.

Hi Kev..... he DIDN'T tune for max HP.....is my theory.......

My bike is down 1.2 Hp between 5750-7250 from initial first runs, (when AF reading was 16.5:1-17:1.) Torque is very similar all the way through...I have a feeling that he spent the rest of the time trying to reduce the AF..

I would have thought that if ANYTHING, my bike at that stage would have had a TRUE AF reading of 12.25:1 ..(not 17:1 as it showed)

(12.25:1-12.5:1 was First "Standard" Bike Dyno run AF reading between 4500- 7250), as I am running 97RON Super unleaded.

So, I think he should have been tuning LEANER, not RICHER, ..but the AF's were telling him the opposite!!

I think the optimal power was at 18:1 (on HIS readings).....or 13.25:1.
But then I think he adjused the probe which gave better lower readings, but i think these readings are still too high (too lean).
My Custom Map has a slightly lower AF than the DNA "Standard" map....but in reality it should be higher.

He said my bike was running very lean when I brought it in.....eh??? should have been 12.25:1 or too rich



They are nice guys at the Dyno, unfortunately they are closed on Mondays, but will speak to them today. I would like to see an accurate AF, which is the weird thing, and go from there.....if it needs another session to put my mind (and everyone else's) at rest, then so be it. They are an Approved Dynojet Centre, very nice people, race at Le Mans, and have a good reputation, so I am sure we can get to the bottom of this!

Keep you posted...

Well, ideally, for maximum power, you should be looking for an AFR between 12.8 and 13.2, in that region, to be getting readings like that, something must have really gone awry!
