Which fuel do you use, What ECU map and do you have any pinging?

Recommended Posts

I am taking out the V11 tomorrow for it's first real ride, probably about 150 miles or so.

I have super unleaded with up to 10% ethanol in the tank now. The bike has the stock map.

 

On my Jackal I can run regular and I get no pinging under any conditions with a stock map. Super is a waste on this bike.

On my Cal Vin with the dual plug heads I run a v11 map with timing retarded a bit and I get pinging, but not too bad if I run super.

On my Breva 750 regular gas works pretty good but I can make it ping if I get on it at too low of RPMs.

 

What fuel works best for you on your V11's and are you running stock maps or...?

I know I can do a bit of trial and error and figure it out but I am curious as to what works for others.

If you can get "hi-test" (91-93 US) non-ethanol, then go for it. Otherwise, I have had excellent results with Shell Premium V-Power Nitro +.

 

Even with diligent "Decent tuning" and stock map (some mods), my Sport pops and sputters more on "other" brands' premium fuel.

 

See to your Decent Tune-up, and find some free-er flowing exhaust canisters that you love. :wub:

My 03 V11 Sport runs well without any pinging. I use 95 RON fuel, Meinolf's ECU map #42, and Titanium cans with everything else stock. It also ran well without pinging on the Titanium ECU programming.

See https://www.v11lemans.com/forums/index.php?showtopic=19682&do=findComment&comment=214669for explanation of fuel ratings.

The fuel I use doesn't have any alcohol, but as I understand it, ethanol improves the octane rating, so should be more resistant to pinging than straight petroleum fuel.

When I first got my bike, it had NGK BPR5ES plugs instead of the correct heat rating BPR6ES. A hotter plug than specified can cause pinging.

You should check your plugs, look for intake air leaks, and correct lean fuel trim, all of which can cause pinging, along with other ills.

And as Docc says, the tune up is mandatory. Don't miss a step. I had to do the tune up twice before I was happy with my bike.

I have done a complete tune. Set to meinhofs .157V and valves adjusted to raceco specs air bleeds all the way in and throttle bodies balanced at idle and 3000RPM. BPR6ES plugs. CO trim at -10 but I am going to set to 0 tomorrow morning before my ride.

Bike starts and runs fine. Sounds awesome. 

I don't know if it pings or not yet as I have not ridden it much yet. I will find out tomorrow. I was just curious what others experience was with their bikes. I am just looking to get a general idea for the V11. It seems to vary considerably from model to model as to what octane it likes.

I see no reason to use premium if it not needed.

I have M4 pipes and foam filters with stock intake tubes and no air box.  (See photo)

A slight ping or cough at low rpms once in a while has been normal with mine. With stock maps, sport maps and even custom maps.

With my Lemans Im running a closed airbox with K&N, Mistral crossover, Mistral pipe and custom Guzzitech map. 91 octane.

My Scura has an open airbox with a K&N, Guzzitech crossover, M4 pipes and a custom Guzzitech map.

Try to stay away from ethanol.

Everything stock here, except for the map.

Custom map, flashed the original ecu.

It took 11 dyno runs to get it perfect.

No pinging anymore. Better mileage, better running, more power.

Well after about 300 miles this past weekend split between two days I have some observations.

 

I have been getting the dreaded coughing in the intake at lower RPMs (around 3000) under light throttle. It was much worse the second day when it was quite hot out, about 90F.

I had reset the CO trim to 0 before the rides. All balanced perfectly at idle and 3500.

I may need to try a different map or tweak the original.

mg77, what was changed in your map to correct your issues?

I have attache a pic of my crossover. I think it's a stucchi. I run pods and M4 pipes.

My plugs look fine. My gas mileage was about 40mpg.

 

My other issue is vibration. I get a buzziness in the bars. My other Tonti bikes are much smoother.

This bike has the original flywheel/clutch assembly from the old engine on a new to me engine, but all the marks are lined up on assembly.

I was concerned about this as I was unsure how these engines are balanced at the factory. Are they balanced with the flywheel attached or only the crank and the other associated rotating mass, rods, pistons, etc.

I know many here install other flywheels and don't seem to have issues. 

What else to look for?

The PO put a PC on mine.  Runs good, never pings

It had a Power Commander on it but I took it off before I even attempted to start it. I guess I could plug it back in and see what happens.

I would prefer to correct it by a new map or altering it in Tunerpro and not use a intermediary device. 

Back in the day before Guzzidiag and Tunerpro there was not much choice but to use a Power Commander.

 

I am not having a problem with pinging.

 

The issue I am most concerned with now is the vibrations.

I feel I will be able to sort out the fueling problems, although reading through the currently running thread 

by not-fishing and his coughing issues and many attempts to resolve is discouraging.

On my '01 V11 (stock, except for K&N filters and a different flywheel/clutch), I've always had coughs under 3000rpm. This was cured up to 70% by doing the decent tune up several times (eventually I got the best result by adjusting idle balance using the white knob, and having air bypass screws just 1/2 turn open. Adjusting idle using air bypass screws does not have a desired effect on my bike) and another 20% by adjusting the CO trim upwards a little (somewhere around +25 now).

 

I have also had pinging on some hot days, with throttle > 50% and rpm in the range of 3500Wow. Not only did some tinkering (with thought behind it, not just changing numbers randomly) with the fueling in that area (increase in 10-15% of fuel) completely solve the pinging, it also caused for a better pull through those rpm ranges!

 

Good luck:)

The tuning was done with Tuneboy, on a braked Dyno by HdeB, after a full normal service. All values that can be adjusted were checked. The map was adjusted with small differences for each cylinder for best results. (HdeB is a tuning specialist from the Netherlands.)

Instructions quoted from Meinolf,

"The base setup, and that's quite important to follow to get the best results, is:

- TPS set to 157mV with all mechanical connectors removed and throttle completely closed

- Both bypass screws completely closed

- CO trim set to 0

- Idle sync with both (if so required) throttle stop screws

- Running sync as usual

 

Target Lambda in my BIN is 0.88 at every breakpoint I can measure at during road driving & logging."

 

 

I did about 85 miles today with a new map by Meinolf and the bike runs great!

All tune up specs are set to his recommendations. It was in the low to mid eighties out and the bike did cough a couple of times but it was random and very infrequent.

If I was trying to cruise at about 2500 to 3000 RPM, that's when it coughed sometimes. But I am calling it cured, because the bike ran fine under all throttle conditions. 

I could roll on in top gear from about 45 mph to 90 with no issue (approx 2000 to 5000 RPM). I don't normally keep it at that low of RPM but I was testing in many different conditions.

Before it had persistent coughs in the lower RPM range under light throttle.

No discernible pinging on USA mid grade 89 octane gas. Power was strong.

 

Still more vibration than I would expect but not terrible, just more than my 1100 FI Tonti's.

Mine stopped the cough as soon as I went to gear driven cams.

I use premium no-lead fuel . I had my bike remapped in Cape Girardeau a few years ago at a bike shop . I have no pre-ignition.
