Tune ECU - Triumph ECU's Programability

[0l0dom0l0]

In the Tune ECU software, you can change the injector timing by up to 250%, does anyone know if the ECU will actually accept this?

Ie in other words are they totally programmable and not restrictive like power commanders?

Cheers

Taking the injectors to anything like that extreme will need a turbo to get enough air in there but the main advantage of TuneECU for tuning is that it gives control over ignition timing, a power commander (not too sure about the latest version) can only alter the fueling, not the sparks.


It also acts as a handy diagnostic tool and can do fancy stuff like re-calibrateing the speedo to account for gearing changes or just makeing it read spot-on...... Must get a laptop so I can plug the Daytona in.

You can plug any value in weather the bike will run is another story. I made I thread about it a while ago and got good results with a little bit of fiddling

Yeah thanks I understand that.

More to the point will the ecu actually accept it if I changed the fueling by 250% or not accept the new map if I've changed it that much?

Triumph should hire the guys that wrote it, or at least pay them something. Probably the best (and free) piece of motorcycle software you can lay hands on. Dont go crazy making alterations, the downloadable maps are as near perfect as I have ever been able to get.

Ahh okay, fair enough.

It was just out of curiosity really, because people I showed it too couldn't believe you would be able to have so much control over the map.

If you could get/borrow a wideband datalogger you can make a fuelling map easily that suits what you want to do.

Want maximum power in the upper rev/throttle openings? No problem, adjust the map for 13-13.2:1 AFR

Want to save a lot fo fuel whan cruising about at 70mph? No sweat, figure out what revs you cruise at and pull out fuel until your AFR is in the 14's.

Want to get rid of that lean stumble at about 4krpm? Easy, find the range where they retarded the ignition to comply with noise & emission regs and adjust the timing to advance it back up.

This is what the software is designed for. On it's own, it's a handy fiddle-tool, which might get you some improvement but for it to be really effective you need to know exactly what's going on, and what your changes did. Even with all that - you can still melt valves and pistons if you do something daft like alter fuelling table cells by 250%

Thanks pete that's a very informative post.

The maps that are available do pretty much exactly what you would need so I'll have a study of them!

If the guys at Triumph, or Sagam were so good, why does every Triumph I've had in have the worst fuelling map possible (after the obligatory trip to the Triumph dealership to be utterly ripped off).

Either the dealers use an outdated map or the 'technicians' dont know how to do a simple download. My thoughts are that the 'official' program has to comply with noise/emmisions regs so its full of flat spot holes. The maps on TuneECU have been tweaked to make fuelling much smoother. BTW, I thought that the Tuneboy et. al. add ons were an eight bit device?
