Self Mapping on the Daytona 600/650

[Spudda]

Did I dream it or was there a self mapping programme on the Daytona 600/650 ?
Something like letting it idle and it would hunt whilst going through 3 fan cycles ?

[Kwacky]

Fire it up, leave it to run until the fan kicks in. It doesn't take long.

Or something like that.

There isn't much of a difference but it can do minor amendments.

[C00kiemonster]

Yep. Don't touch the throttle at all while doing it

[Stonesie]

Yep as said just start it up and do not touch the throttle until the fan comes on, it's an "Adaption's re-set".

[Blade]

Intrigued how does it self map on a closed throttle in a totally uncontrolled variable environment?

[Kwacky]

It's very minor adjustments to the fuelling, nothing more.

[Blade]

How does it know what minor changes to make is my point? I can only see it being able to measure temperature change over time, on a closed throttle and air mass and air pressure in the circumstances described and therefore any changes that are made would only be suitable for the conditions at that time, which lets be honest will most probably be different by the morning.

I honestly dont see what even minor changes could be beneficial using the extremely limited scope of standard fitment, on engine sensors or am I missing something?

[Kwacky]

You're reading too much into it. The technology is well over 15 years old. It's not as powerful or complicated as modern tech on vehicles. All it does it to reset the sensors.

[Blade]

So it's not self mapping it's a factory reset?

[Monty]

It’s not self mapping, it just sets the base map/AFR to the current air temp and pressure.

[Blade]

It’s not self mapping, it just sets the base map/AFR to the current air temp and pressure.

Wheres the advantage though? It would need mapping every day or upon any significant weather change to be relevant if that's what it's doing.

It almost sounds like they didnt give the bike a decent base map in the factory if it needs tweaking for small changes in air temperature and pressure.

Sounds like magic to me

[C00kiemonster]

Its useful if you change end can, air filter and the like as well as if the ambient temperature is much higher or lower than last time the bike ran.

Clever system really, saved a load of remapping and definitely improved the bikes fuelling when required.

Triumphs are magic - always have been.

[Blade]

Haha Triumphs are magic. A late discovery for me, but better late than never

[Monty]

I may be wrong but didn’t also reset the TPS

[Kwacky]

Yep.

[Blade]

I may be wrong but didn’t also reset the TPS

That would make the most sense of all.

[C00kiemonster]

I may be wrong but didn’t also reset the TPS

Yep - which is why if you touch the throttle at all it doesnt work.

[D41]

And you didn't actually have to let it do the 3 heat-cycle-thing either. Three on/offs with the ignition & kill-switch (or something like that) was all it really needed to reset everything. Takes about a minute to do it.
