Yeah I'd figured that out, lambda makes sense to me.
Prices I've seen for Target tune here are the equivalent of $680! I might see if I can pick one up when I'm in Florida in August.
Ah I see you in England (where I come from) so we are in almost same time zone 😉. Yes the prices in UK and most of EUROPE are ugly for DJ stuff. I get mine in the USA. I have seen it in Germany for 450. You can buy the TT module alone and source the WBs for a lot less (they are standard Bosch items available on Amazon but you need to handy with wiring for the connectors.
good luck mate - and keep us posted. BTW, DJ UK are a great bunch of lads and a full Dyno Tune from them is priced really reasonably. And I assume you know my mate Alex at Fast Lane?
I tried to set the gauges up to show the things you said, but couldn't find AFRs other than WBO2. Regardless I set one up to show MAP, TPS and RPM and checked it in different situations as well as logging the data.
There was a fair amount of filtering to do on the way home because of an accident so got some decent mixed cases.
I've got a lot of thinking to do about what I saw, it seems like there is a very narrow range of MAP and TPS that covers all the situations, either filtering, cruising at 50 or riding somewhere near the speed limit.
I could go and get a dyno tune from someone not to far from here who I know will do a good job, but I like messing about. I don't know Alex personally but will be sending some heads to him as soon as I can.

hmm may have sent you on a wild goose chase - with the stock narrow bands monitoring the AFRs doesn’t work so well but looks like you got yourself a panel that is useful. TPS and MAP covering most situations sounds like you not working the bike much. If you can afford it rather than sending the Heads get Alex to do his ride in right out service and have Cams, heads and Dyno done. He will take it to the Dyno. He will use your PV and his Autotune WB set up so you can save that cash. What you get is really worth it. Well worth the ride up (even for me coming from outside the country). He has done two bikes for me. We did a lot more to them, welded trued cranks, gear drive for the Cams, bigger bores, headwork and everything else that made sense. But you bike fresher so CAMs and heads will give you some magic without too much hassle

I was trying to adjust the brightness on my PV and with the brightness level BUT I took the level all the way down to zero , and now I cant see the screen well enough to change the settings back to normal ,basically the screen looks blank(off) ,trying to adjust it back to normal I must have touched another setting so I am no longer on that setting .Is there a way to resolve this problem . I connected the PV to my laptop but there is no settings to change it unless I am not looking in the right spot ,due to my frustration or anxiety from not being able to get it fixed ,tried for about an hour and nothing
.On a side note when I first turn on the bike and the PV goes on the screen is normal (bright)it shows the trademark sign and then when it gets to the icon windows , that is when it goes blank (dark), so low I cant see anything but faint shadows of the icons .
I feel like I now have a half decent understanding of the product and the options on tuning specific things. I've run a few datalogs and am analysiing them in megalog viewer. I'm monitoring knock count while riding to give some clue of when to hit the log button for specific cases. One of those specific cases happened when I was riding on a closed track, simulating a high speed run
I could basically get the bike to
continually knock in a certain area but it's a pretty wide range of MAP/RPM What's the approach here? Timing or fuel first? The tune (file extension changed to .txt) and log are attached. I'd starting making changes to the tune already as per the screenshot below (to cover a different issue).
I'm off to spend some time autotuning today and will log some more after that.
Before I went to do autotunes remembered something I'd seen about high MAP at idle. Mine was 42-45 so spent a bit of time looking into that and changed my Ce table as per https://www.hdforums.com/forum/the-d...l#post15078750 just to see if it changed. Instantly down to mid 30 so I left it like that and spent a couple of hours doing autotunes.
There were lots of changes accross 4 or 5 sessions and even after all that the last session still had a 5% change cell.
Went and tried the high speed knock event again and it was still present. Trying to answer my own question as to fuel or spark I quick tuned a +10% global fuel. Still had the same knock (not audible) then reversed that and removed 5 degrees of global timing and still had the same knock
.
It seems like a significant event if the bike is puling 9 degrees of timing out.
What next?

Redid gaps to 0.037 still did it. After all my playing about with CDE etc. it is now overheating while splitting lanes again. Must be patient and not ride it off a cliff

decide on your AFRs then to the VEs - is unlikely ignition needs playing with but go to it after the fuelling decided and locked in. For lane splitting what percentage TP, what MAP and revs you getting the issue at? Assuming you are using gauges on the PV.
or jump the gun and without WinPV just use quick tune to adjust the VEs up for the low / overrun revs to see the difference
above all assumes your ignition MAP is stock of course
