Street Triples, Power Commanders, remaps and stuff.

[chickenstrip]

So I have this Striple, on an 11 plate (refer to as 2010 Striple?) and it has a PCV fitted. It is my first FI bike since my Kwak Turbo, and I know less than FA about all this. It seems to run sweetly, no complaints there, but I'm shortly going to replace the can (aftermarket, single), and was wondering if I'm likely to have to remap? I also read somewhere that this model of Striple shouldn't have needed a PC, as maps are available online for the original Triumph set-up, which was changed on later models so you couldn't do that anymore? Enlightenment welcome

I mapped my own with a cable.

I'd just change it mate, its likely been fiddled before.

I thought it was only the latest that were locked down and could not be remapped? A Power Commander is a waste of money if so. What shape lights does yours have?

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

I know nothing about either PC or TuneECU (I did use TuneECU to balance throttle bodies but on my version of the ST, the ECU is 90% locked, so that's all I could do).

Does Power Commander come with software to help you make a map?

Does TuneECU allow you to make/tweak maps or just upload them?

Could be a previous owner didn't realise that a PC wasn't needed, or it gave them more options maybe.

EDIT:
In response to the question about cans and maps. Generally, if it's just a can and you are leaving the baffle in, you can probably run it on the stock map.
If you run baffle out, or use a full system, then a remap is definitely needed.

I got mine mapped by Triumph to their Arrow can map and noticed.....nothing.

[chickenstrip]

I know nothing.

The PC sits there under the seat. There is nothing in amongst the bike's documents about it.

I'll swap the cans when the new one arrives and see how it runs. But would be nice to start learning a bit about this stuff. I do have a clue as to what remaps can do/are used for, but no in depth knowledge.

Not trying to teach anyone to suck eggs on this. Tune ECU and Power Commander are doing two different things.

Tune ECU is remapping the ECU directly.

Power Commander is a piggyback module that applies a correction to ECU's fuelling value on the fly. You can rip the PC off and it'll be instantly returned to stock.

Unless I'm misunderstanding Tune ECU.

As an aside, does your Power Commander have the auto tune module, or has your o2 sensor been eliminated?

Teach away! I have the most limited idea of what it all does and how it does it, so anything I can learn has to be a good thing.

I don't know about whether it has an auto tune module or whether the o2 sensor has been eliminated. Don't even know what I'm looking for to check

Edit:Oh, ok, I see the auto tune module on the website - haven't seen one on the bike, certainly not under the seat with the PC itself.

Id still be wary of any off the shelf map for exhaust or filter changes being 100% perfect.

If it were me, I would change the exhaust to the one that you want, and then pop it on a dyno for a run to check if it's rich/lean anywhere in the load/rev range before tweaking the PC or downloading a new map to the factory ECU as appropriate?

Auto tuning from what I have read can only get you so far too. As all ECU's ignore closed loop inputs at WOT and high rpms, and use the factory programed look up tables.

Also having read about self mapping and auto learn functions with ECU's, out on the road you can never tell the difference between 1-2bhp etc when small corrections are made. Many decent automotive ECU mapping experts would agree that the only way to map an engine to get the absolute most performance at every speed/load is to run it on a dyno and take stabilised power readings at every load site.

I agree that a good factory developed map or an aftermarket product manufacturers worked out map should be close enough to get like you say pretty decent performance and drivability and often better these days than std emissions and noise friendly compromised std factory maps.

I do agree that mapping ECU's even on a rolling road is open to variables and isn't perfect. Auto tuning is possible with aftermarket units, but it's only as good as the parameters you tell it to use. For example all engines are different and you or I would not know what amount of ignition advance or air fuel ratio will give the highest possible power output, and if we changed it a few degrees either way and found 3-4bhp, we couldnt or wouldn't feel it or know what setting was giving max
Bhp.

I'm having aftermarket management fitted to my car this year and am looking forward to watching it be live mapped on the dyno and see how they go about it and arrive at the best settings via monitoring o2 sensors, knock sensors and being able to use interpolation between points and cells.

At the end of the day if the bike with whatever pipe fitted pulls smoothly through the Rev range without flat spots, black smoke or hesitation, and does not pop and bang on the overrun it's probably a good enough map anyway.

get your PC hooked up to a laptop via the free PC software. itll back up the map you currently have stored so worst case you can put it back to where it is now. i doubt someone would have gone to the cost of a PC5 without another mod having been done. I've only had the PC3 on an old 929 and whilst plenty of different maps online for just a race can type mod (they are all 50mm straight thru baffles) I had to get full exhaust replacement maps loaded before things actually started to get faster rather than just nicer to ride!!
