Correct way to auto-tune:
0. Always tune well heated engine - not just coolant temperature but the engine block (oil) must be heated up to at least 80C.
1. Have auto-tune off in normal conditions
2. When you ready to do a tune run, flip the button to enable autotune and twist throttle to "required"% gradually over vise ECU will do "accelerator pump" enriching mixture momentarily (yes it does that). So start with 1500 - 2000 pm with a goal to get to required tps position when you hit 3000 on high throttle openings and less on the lower openings. When you hit rev limiter, flip button again to disable auto tune so it would not f@ck up the map during engine breaking/neutral throttle.
3. You need about 10 runs to be sure PCV got it right.
4. Repeat point 2 for 100%, 80%, 60%, 40, 20, 15, 5, 2. You will not hit rev limiter on lower throttle openings, so flip the button when RPM stabilize.
5. You need to have linear proportional YCC-T map to do precise tuning. You can change it to anything you like later.
6. You need to have something indicting your tps while you autotuning - for example power commander LCD unit. You can also use same unit to datalog to SD card and then re-calculate fueling corrections based on that log.
7. When you done - accept changes to PCV fuel table.
8. Repeat the same process at least 5 times.
9. Now flash PCV map to ECU.
10. Repeat all above another 5 times at least. Watch out for errors in mapping. Your experience will grow so eventually you will get it right.
I would recommend to auto-tune on gear 4, so you have reasonable load, and time for AT to sample.
Elwin sorry was a big delay in my last posts

Hmm must say, the most consistent and professional information about pcv+at GREAT WORK. I and marider can send you some small pocket of money as support for your further work and effort which you already done.

The only reason a "square" YCCT map would be useful for this tuning method is so that you could keep the TPS constant by keeping the throttle tube in a constant position so as to populate map data in whatever TPS you are shooting for. Is this what you are indicating? Otherwise I'm not sure I agree...

You still have yet to answer this: If you are tuning on a dyno (unless it's a really old one or one not designed for a bike) why would you tune to a target AFR rather than tune for performance? As a matter of fact, it would be better to tune to a target AFR on the street than it would be on a dyno. It's hard to say that any dyno would be able to simulate the effects of riding through the wind at over 100mph. Yes, I realize there is speed compensation built into the ECU which is supposed to make of for the difference. The reality of it though is that it's not an exact compensation, just one that is supposed to work "good enough". Tuning to the target AFR on the street vs on the dyno will minimize any error due to the speed compensation. Especially if you weight your data based on gear position with say 3rd and 4th having the greatest weight while the others gears have proportionally less weight.

I definitely agree with on only auto-tuning with a warm engine for the same reasons you wouldn't set carb settings on a cold engine. You are also correct about throttle transients causing an "accelerator enrichment" effect. Regardless of how you auto-tune you want to keep throttle transients to a minimum when collecting data.

Alright boys I finally got the interface and now I'm lost. We don't have any dynos in our country so I have to rely on the community for help.

Can someone share a good map for my 2011 otherwise stock except for a racefit black series single low mount exhaust. It's a 3/4 to 1/2 system I think.

Our temps here are between 25 to 35 degrees celcius, high humidity and our octane rating is not the best so ignition map can't be altered much I guess?

I'm mainly looking for a good fuel map, reduced engine braking and usable A mode as it's pretty un rideable in A mode right now. Maybe a slightly altered ignition map too? And an explanation of the flash would be helpful.

It would be great if we had a database of some sort of the flashes. Sorry I can't search through the entire thread as I'm using this forum through the phone app.

Thanks in advance.

Go into the FAQ and read it. Then grab the Peen V2 ECU image from the link in the post. Use that for a starter.

Thanks mate. I got peen's map now. Is the explanation of the map in the zip?

My bike is Japanese or Australian or European. Where can I find the stock map if I ever want to go back to stock?

I know I'll lose the immob and don't care but can't go back to stock settings? There is a base US map, why not European?

I can't find any notes about what peen's map changes. Anyone?

Dear, I have a full set of genuine ECU(EU) with 3 keys(red) and immobiliser and full EU harness!!!!!!. ECU(eu) is orignianal without flash I wonder that maybe somebody of you need this as the replacement or spare ECU also maybe somebody would like to convert his US bike on EU harness and (eu)ECU if yes give me PM. Price is really low for r1 forum guys

EU(ECU)+Immo+3 keys(red)+EU harness

ECU(eu) 2009/2011

Also can send pictures. Maybe FT will be interesting to get a full EU harness with ECU, what you reckon ?

Didn't the newest version of the software have the stock EU ECU?

So I'll have to resort back to a US base map? Is that ok on an EU ecu and wiring harness? What are the major differences between the 2, any links to read up?

so just a question to be clear.
I set the tps on a pcv so it is zero with the engine off effectivly 7 voltage.
then when the engine is running it rears 2% throttle on the power commander.
and 100% is normal
then it is ok just to flash the pcv map into the ecu?

I am going to the dyno next week and plan to tune then flash and check but dont want to redo because we stuffed it all up. reading the thread it only effects the lower throttle openings like 2 and 5%?

I can't find any explanation for the changes this map makes. Can someone point in the right direction to read up?

Does this smoothen out the twitchy A mode on/off throttle sensitivity? Does this apply uniformly to all modes? I'm a little wary and want to be sure before flashing as once done there is no going back. Flash tune has zero documentation about their interface and software so this forum is my only hope.

im in the same boat. what would flash tune do without this forum.

i'm learning, so i need to apply a PCV map to base maps even to the 2012 R1 y-pipe & slip-on.ftm map. How do I find the right PCV for my setup which is a GYTR slipons and mid y pipe?

im EU too

so do i need to buy pc and auto tune to create a custom map with my exhaust mods or one that someone made will do?

R1evotion, is this what u are doing? a pcv for 12?

Oh and 1 more thing; I'm not sure what ignition timing is Peen's v2 based on but if it's for 91+ octane then I'll need to lower it for my fuel. What's the octane that the stock ecu map is based on? And how do I put those values in peen's map other than manually cell by cell?

Hello Sydster,

I have spent over three months building some very good maps for my Australian 2012 R1 but I got fed up with not being able to get that sweet spot with the tune when just using the Flashtune...I now use a flashed ECU (no 02)with a PCV and Autotune and this combo has worked so well!!
I'm finally happy with the tune.
It is by far the best money you could spend and In my opinion you need all three..the PCV allows a map to be built for each gear, the Flashtune allows you to disable the 02 and run TPS vs RPM fueling (better for tuning the whole map), and the autotune trims the map for you getting it almost spot on.

If you want a FT map made for a Flashed 2012 r1 EU spec running 98 fuel
y-pipe and GYTR's I have one 99% ready to go.
Just send me a PM if you want it.(it was built by running the Auto tune over the map for a 12.9 AFR on my Flashed ECU)
