what octane fuel are you running and what's your elevation? i assume it's pretty close to sea level, but not sure. you're lucky that DynoJet has a almost spot on map for your setup ;)

Hi

I am at sea level & our octane here is 95 Ron unleaded. Fuel is very similar to UK. I found using the Two Bro's map it was too lean in the lower revs. I added some of the other maps available data & came up with the map I attached.

Thanks

Does the PC-V know what gear the bike is in and have a map for each gear :question:

One issue I can see is the bike fuels differently in each gear, and again in each mode, this equates to 12 maps, I would assume the PC-V is gonna get confused and always be trying to re-trim, on fast roads it will all be higher gears / revs, but when reaching tight switchbacks it will be way off as the fuelling will be very different in 1st - 3rd.

I am thinking of maybe using a PC-V and running the clutch mod all the time to "lock in" a single map on the ECU for the PC-V to adjust to.

To my knowledge, there isn't any AFR modification between modes or even on the clutch mod. My understanding is it affects the throttle dampening only and perhaps unlocks the power restrictions in the lower gears...

With regards to riding different styles of roads - whether you're riding tight switchbacks or WFO on the interstate, you're still in a throttle position/RPM range on the fuel table/AFR table. That's all you need being monitored/changed and that's all it does.

Think of it this way, if you're engine braking hard going into a turn, your throttle position is 0, or close to it so you'll be in the closed loop where the Optimizer is going to try to achieve a 13.6 AFR. If you're outside of closed loop, you'll still want your motor to get that same AFR you programmed in whether you're in 2nd at 4500RPMs as you would in 6th at 4500 RPMs.

Most times you'll need to manually plug positive fuel values ~7 in the closed loop for the optimizer to get that magic 13.6 number. I've got 11's in my closed loop, for example. Even if I had 15 in there, it's still only going to take the fuel it needs to get a 13.6 off the Autotune O2 sensor

You can also go in and manually change the 02 optimizer settings as well..

The PCV can know what gear the bike is in, and use six different maps, one for each gear. You can autotune all six maps.
The PCV will not know that you have changed the mode on the bike.

How can the Pcv know what gear it's in? :confused

You have to tap into the speed sensor, run a wire to the PCV, then turn on gear advanced maps. When you do this, you will get 6 zero maps, so make sure you have saved your current map first. Copy and paste the numbers in the tables to each of the 6 maps and you have gear advanced maps.

Guys,

I have just had the ECUunleashed flash and a PCV fitted and dyno'd. (No Autotune, only optimisers)

I haven't ridden it yet but I know the tuner has sorted it for max power (that is what he does !).

My question is: Is it worth producing another PCV map for economy (power is not my concern - driveability is.) The tuner states that as the bike is tuned for max power, any leaning out will reduce power, resulting in more throttle use, negating any gains from leaning.

Or is it worth sorting out some method of sensing the speed and just changing the map for 6th gear for cruising.

I have not seen any reference to any one sorting out a speed sensor, bar some references to a 'blue wire', which I assumed were from/to the ABS rear wheel sensor. If anyone knows if this works I would be interested. EDIT: found a reference to it for the speedo healer. Its the blue wire from the ABS unit to the ECU

Also, I think I have this right, the central closed loop area of the map is set by the PCV at 13.6. Is this adjustable and would I want to adjust it ??
I appreciate that most will have used the Autotune that I do not have.

Obviously, I am new to this malarky.

~TABASCO~ If you read this:
If I read correctly what you wrote on the ADV big thread, I am a bit confused about the O2 sensor thing. You state they are not needed by the Flash and you have removed yours but then go on to say the PCV finishes the tuning job off. The problem is that the PCV for the S10 is specific and comes with O2 optimisers that require them to remain. Is it possible you have a different PCV version installed and yours did not come with the optimisers. ??

Cheers Ray

Hey Ray, seems like everyone is busy.. lol
I know of two others that have either removed the PCV or have zeroed out the AFR map. It does seem to work.
If you save the map you currently have. Name it something you will remember, then zero out the tables and send the new map to the computer and see how the bike runs. I don't think you will notice that much of a difference.

I'm not Jaxon, but this is only to try and help you until the others arrive.. ::025::

Jaxon and I both had the same PCV with everything including the Auto Tune.

Ray,

One thing to remember is that the re-flashed ECU no longer uses the closed loop operation and the o2 sensors are taken out of the equation. I have removed mine once I had the ECU re-flash. The optimizer for the PCV is used for a stock ECU that is running the sensors in closed loop. I have had to add a PC to my re-flash as it was still to lean in certain areas and I have also made other mods as well that further lean out the bike.

I e-mailed ECU Unleashed by e-mail and asked them direct if my optimisers are superfluous.

Post up what they get back to you with as it would be good to have it confirmed. I emailed Ed at AF1 racing where I had the ECU unleased re-flashed done. One of my questions was if the re-flashed renders the closed loop operation obsolete and that I would no longer need to have the sensors attached. I have removed mine and get no FI fault light on the dash. The jumper mod does the same thing.

For the folks that have the flash,,,, you can take out the 02 sensors and remover the optimizer... I don't know that the CJM removes the need for 02 sensors all the time.... Keep this in mind, the CJM might or might not turn the 02's off sometimes... That doesn't mean they have them "turned off" 24/7..... If it where me, If I was running the CJM I would leave the 02's in and the optimizer... Your not hurting anything.. And again, if you have the flash you can take all that off...

If you have the flash with a PCV, I would suggest you go back in and add fuel to your 'closed' loop... you will be running lean for sure.. Also, add above 4000..... The flash doesn't account for that.............. If you have AT, it will do the home work for you.....

The optimisers (if indeed they are functioning at all with the flash) set the AFR to 13.6 for all the closed loop area. Are you saying this is too lean ??

Can I assume that, if as you say the O2 sensors are unused by the flash, the AFR will still be 13.6

BTW, no reply from ECU Unleashed yet.

The optimizers are not used at all with the flash... I have found with my bike that 13.6 is to lean in closed loop with the flash.... What are your bolt on engine mods and I will try to help... Are you having issues ? If your bike is working good you might want to leave it alone... But what ever you might need let me know and Ill try and get you going...............

Thanks,
My bike is otherwise stock. Just the ECU unleashed flash and the PCV with optimisers (that come with it automatically for the S10).
I have only just collected it and I have to say it is much more responsive but the snow was/is down and in the UK the road salt kills bikes so I cannot test it properly. I have no problem with rain and cold but I avoid using the bike when there is salt on the roads.
One thing I did notice was there is very little, if any, difference between T and S.
AFAIK I do not have any problems, I am just trying to understand what I have bought. I am going to plug in the laptop today to see what I get.

My only possible mod was to be a leaning out of the bike at cruising speeds but if 13.6 is already lean then I will leave it alone. My issue (if it really is one), is that I have the optimisers fitted and the bike has been tuned with them and it would appear that the tuner who tuned it on the dyno, is unaware that the flash negates all use of the O2 system all together.
Does this make sense ? He states, as do Power Commander, that the closed loop area is set at 13.6, bit if, as seems apparent the O2 system is negated then I really do not know what I have got or what internally has been used to tune it.
Like I said, so far it seems to run well but I have not been able to test it fully yet, so I may be/am just being picky. But it does appear that I have a lot of electronic gizmos in the bike that are just adding weight.

From ECU Unleashed website, regarding the S10 it says this: Remove Closed Loop Routine For Use of AutoTune Air/Fuel Modules so in reality, I have not got a clue what is or what is not working.
