Dyno tuning

[Ralsmith]

PCV is just adding or removing fuel so if your map is close then you will make tuner job easier. Also remember that your map may have ignition timing changed from stock which the tuner will not have access to and could effect overall power and torque. That is why the TuneECU would allow for best tune as it can access more options than PCV. It is a shame that not many folks use it, probably as you cannot do live tuning but need to log, make changes and then recheck

I do wish there was a tuner around that tuned with tune ECU but there isn't.

So a tried and true approach -- but remember, this is a long chain of details that matter, and we are only as strong as the weakest link -- is to mount the Power Commander for the dynamometer run, ensuring it is zeroed before the run, then have the operator connect to the DynoJet and do the run, loading the resulting trim tables on the Power Commander.

Then remove the Power Commander, and connect to a computer with the DynoJet control software (free download from their site), and download the trim table from the Power Commander. Then send your map along with the trim table to someone with a special version of TuneECU who can combine the two, and return to you a new, tailor made for your bike, base map. Then put the Power Commander on the shelf until you make another major change to the air/fuel/exhaust path, and need to repeat the process.

To your question, my understanding is it is best to start with the STOCK OEM map that was delivered with the bike (or last one updated by Triumph).

Your needs, your results, may vary.

That seems like a long, drawn out process. Would the end result be worth going through all that? The tuner I used was not familiar with TuneECU, so mine was done with a PCV and Dynojet tune. He ran into a problem finishing the tune and had to wait for software to get into the ECU and finish everything. While he was at it, they lowered the temperature the fan kicks in by 5°. Everything seems fine now. Seat of the pants feeling is power has been increased significantly and it now makes a cool intake noise with the K&N pod filters. Final results are attached. I'd like it if the tuner had run it before on the dyno so that I had baseline numbers with just the TOR's and Triumph tune...

As long as you're happy.

I would think (gets me in trouble now and then) that custom tunes like my current tune ecu map would have the best timing.

Power Commander installed and the bike still runs

I'm calling Monday to schedule a tune.

 

[Joesmoe]

Good luck. Of course, we'll want to see the results.

I'll gladly post them.
