Hi guys,

I installed a Rapidbike Evo unit about two weeks ago on my 2020 Classic, with Ti headers and K&N filter, no flapper valve. I've taken it for a 450km run in the hills and a few shorter rides around town, making sure to give it so.e full throttle accelerations through the entire rev range.

It seems to be adding a heap of fuel at lower throttle and lower rpm, but reducing fuel at wide open throttle above about 4000rpm. Seems weird to me but is that what others are seeing?

Also, can anyone explain what the pump correction setting is and what it should be set to?

Also, what should the O2 sensor in the auto adaptivity screen be set at? Mine came set at 48.

Lastly, does anyone know how to raise the rpm limit? Not sure I will, but can't even see an option for this in the software.

Cheers, Dom

I'll have a look at what my maps look like tomorrow, I've run around 300 miles with the EVO on Auto Tune, I've got a full Zard SS system & MWR performance filter in mine. I haven't ragged the bike up to the top end generally running around 4-5k mark on the road.

There was a post a while back about the Auto adaptivity over fuelling if running at low rpm for extended periods, although I guess that won't apply to your situation
Excessive Fuel Consumption with RB Evo

I'm guessing that's a selected map from the software and not with the auto adaptivity added.

I could have it wrong but I thought the selected map stayed the same and the auto adaptivty was added on top of the selected map (seen in the auto adaptivity tab of the software).

I believe the pump correction is an option to enable the fuel injection to act like an accelerator pump in a carb where it enriches for a short period at selected TPS settings, I've got mine disabled. From the manual it appears that the full functionality is only available with the Race module.

I'll check my Auto adaptivity setting tomorrow, I think the manual tells you not to mess with it unless you put the bike on a Dyno.

No clue about raising the RPM limit as I don't want to, but I'd doubt you could as the EVO only adjusts fuel annd I couldn't see anything in the manual regarding raising the red line limiter.

Have you tried reaching out to Dim Sport, usually I've found them quite responsive?

I started with the base map provided by Rapidbike and auto-adaptivity set to +-15 max enrichment /enleanment.

The base map already had additional fuel at low rpm/low throttle. But after a ride the auto adaptivity maxed out the +15 fuel across a large range of low fuel / low rpm. I applied this correction to the base map. This reset the auto adaptivity to zero.

After another ride this occured again, and I applied the adaptivity settings to the base map.

Part way through the ride today the throttle was very snatchy on/off. Later on even at steady state throttle (low and around 3500rpm) the bike sounded and felt not smooth, almost warbling/stuttering.

I will contact the distributor and reset the base map back to original and limit auto adaptivity to +-5 max for now and won't apply any changes.

Cheers, Dom

Oh, and fuel consumption went from 260km before getting the reserve light to 180km.

I'd be very interested @DomNineT to hear the responses if you'd be so kind.

In the meantime here are my maps, similar sort of thing, maybe worse..............need to check fuel consumption. No changes to base maps all changes from Auto Adaptivity

 

[DomNineT]

That looks reasonable at least. I had +40% across a huge patch of the base map and an additional 15% across way more cells on the auto adaptivity. Guess thats why fuel consumption was 50% higher!

 

[Weegie]

Were you running the stock map before adding in the Auto Adaptivity settings @DomNineT ?

You can see I'm running the Zard Map, but yeah your maps look a lot richer.

Does appear Auto Adaptvity likes to add large fuel corrections at low throttle openings, on that other thread about excessive consumption a couple of guys reset the auto adaptivity and reduced the correction factor to +5 & -5, to limit the over enrichment.

I'm intrigued as well and will plan to save the configs on a regular basis to see what changes as mileage increases

 

[DomNineT]

Yeah zard map for met too.

Kind of makes the auto adaptivity seem useless if all it does is continue to add fuel to infinity. Obviously doesn't really work then. Setting to +-5 just seems like a work around. The question is, why does it keep wanting to add ever more and more fuel despite clearly running way way too rich.

 

[Weegie]

It does seem problematic and should you put this to DimSport I'd be interested to hear what they say.

It seems to be a recurrent problem with the EVO at more modest throttle and rpm settings, which is exactly where most road bikes run (I'd guess, certainly where I tend to be)

I'm going to persevere next year and see if it reduces any, with the narrow band lambdas being more or less digital in nature, perhaps more miles are required for the long term trim to get dialled in

Be good if you would stay in touch and we could swap notes.

The only other choices, barring some sort of firmware update to the Auto Adapt Algorithm, is to disable it (partially or completely) or install a wide band lambda, but that's quite a bit more cash and hassle.

 

[DomNineT]

Yeah I will definitely email them shortly.

I reset the map to the base Modified/Zard map and limited the auto adaptivity to +-7. Bike ran 100x smoother and stronger immediately. I may turn the auto-adaptivity off altogether for now - at least until I get some answers from Dimmsport.

Not sure if there are any Dyno-tuners that work with the Rapidbike module in Melbourne, but I may check that out. Pity though that the auto-adaptivity was the main purported benefit - otherwise why not just apply a map directly.
