2006 R3 Classic tune

[vindex1963]

I had my Classic tuned in Phoenix at 1000ft elevation and live in a town that's 5000ft elevation. I brought it back to him yesterday to do a re-tune because of how rich it's running. Back down in Phoenix air/fuel was spot on 14:1 under 20% throttle 13.2:1 over 20% throttle. I installed an Innovate air/fuel gauge and it read what he was getting. I rode back to Payson at 5000ft and the air/fuel looked good....for now and that's the strange part. If the ECU is adaptive shouldn't it adapt to maintain not change the air fuel?

He only changed 80% and 100% throttle air fuel and in the 0% throttle he had 20 in each cell to remove decel pop and he changed that to 2 from 3000rpm down to idle rpm.

My base tune is 20222_2SA tune and he custom tuned the Power Commander 5. TPS is at .63, stepper is at .75. Throttle bodies synced.

4000 ft difference is NOT to be sniffed at. There is well over a 10% (closer to 20%) difference in O2. A PCV generally is set to 20% max if AutoTune is used. I would STRONGLY suggest autotune and a POD300

So the 2006 Classic doesn't have the sensors for elevation changes? I have an Innovate air/fuel gauge installed and went for a 120 mile ride today, the air/fuel looked good but if the bike adapts by rewriting the base map that might change.

Of course it does. BUT the base tune is rather generic and from experience runs a bit lean at sea level - the sensors and such as well as the margin for adjustment are correcting and ime at 1000metres the mix was better. - You have corrected the lean at 1000ft and now risen such that the mix is over corrected.

And yes the base tune is adaptive up to point. I don't think the correction is linear.

BUT - if you have removed the OEM lambda - then the ECU's chances for adapting much are negated. And with a PCV in you have pretty much with certainty done this. The dongle. You are now running a close to NON adaptive map. The ECU will adapt and refer to it's Lambda value for confirmation. But with Dongle it's always perfect. So it stops adapting. Or modifies with no form of checking whether the changes were good or not - the Lambda value is always perfect. See my point on correct NOT being linear.

Here is where an autotune would benefit you. You can have your tuner work away at 1000ft and the PCV with a WIDE BAND O2 sensor will maintain the AFR values he sets. Ride home - and run a tank of fuel through and look at the PCV trims. As long as they don't all cram up on the max correction value you're OK. If they do - chat to the tuner.

With the POD-300 you will see what the PCV sees. And can log data. I don't know if the Innovate logs data - but believe me you will have to log a lot if you intend to correct the F tables yourself.

IF you decide to take the AutoTune route - I STRONGLY suggest using the map/gear option. And if your tuner is up to it - asking about tuning the PCV using Manifold pressure rather than Throttle position. It way more complex to do well, but imo works way better.

OK vindex1963 - So here's some "maybe" useful info.

I am preparing My 2009R3 for it's (once every 2 years) MoT test. And to stand any chance of passing emissions I have to refit the cat and Original pipes.
So I put the OEM tune back in the ECU and set the PCV to "0". But left the PCV dongle in and went for a run with the WideBand AutoTune O2 sensor in and let the POD-300 record.

At lowish (think ordinary light traffic up to 70mph) the measured AFR is richer than 14. It get's a bit leaned out higher up the rev's, think 4000 up. So I have had to set the PCV AFR target in the lower rev range to a leaner mix to stand any chance of passing. I have my PCV set map/gear so only altered 1st, which according to DynoJet is also applied to Neutral - which is how the AFR is measured for the test.

Yeah - it's basically a "Volkswagen" solution to emmisions testing. Yes - I'm a bad man.

Made a change to ride the R3 "silenced". Quite enjoyed it tbh.

Test booked for Monday - after which I will decide what happens next.

Update, the air/fuel is right where it should be here at 5000ft elevation. I rode it down to 1000ft elevation and the air/fuel stayed the same, I don't get it but as long as
it's all working correctly that's good. Strange things happen with these bikes......

The ECU is basically a black box
