I would defer to your expertise. My experience with this comes from my interactions with Wayne in dealing with his Tuneboy program and from others on these forums like Pig9r and Toystoretom who have also struggled with it.

I completely disagree, as, if you actually want the engine to run right, you want to get the ECU to stay out of closed loop mode.

My bike runs fine in closed loop - except for popping on decel at zero TP. This isn't really a performance issue. Using a modified version of Wayne's 20050_2 tune, I have smooth power curves with 140 max HP and 150 max torque. Everyone with aftermarket pipes has the backfiring problem. After consulting with Wayne on this. He sent me a logging program and I sent him manifold pressure, TP, and rpm data. We used these to enrich the lower rows of the L tables. This seems to work pretty well.
Pig9r and ToystoreTom tried taking it out of closed loop by lowering all A/F below 14.57. They couldn't get it to idle or run right at low TP. That's all I know about that.

Could be, but I see no reason to leave the L tables untouched. On every single Triumph I've ever tuned, the bottom few rows of %TP/MAP had serious room for improvement, which when left unaddressed, left annoying driveability problems. Attempts to tune this area could reveal that no improvement can be made, but I seriously doubt it, as I've never seen such a thing.

Like I said, the only problem at low TP seems to be popping on decel and we addressed this by adding fuel to the L tables. The tune I created with Wayne's help is posted on the r3owners.com site under "trading tunes" on the first page. The tune is 20050_DynoFinalMap_TOR_CatBypass_decel.dat. I put fuel in the 0 MAP row and from about 1500-3500 rpm up to about 656 millibars on the left axis.

I would add and subtract fuel wherever needed. Besides that, Wayne told me that the trims affect both F and L tables. Did he not use the trims? Or did he change his mind about whether they affect both?
|
The trim application in TuneEdit does affect both the L and F tables but I don't know if this is the case if you use the TuningLink emulator. Wayne should have separate trim functions for the L and F tables. If you compare Wayne's custom dyno tunes with the stock tune (20050), the L tables are the same, so I don't know how Wayne did his dyno tunes.

Once again, I don't care about PCs. My question pertained to using tune edit. You may want to re-read.

My Triumph mechanic is a DynoJet center who does most of his custom tuning work on Hardleys. He's the only dyno tuner in Reno who's competent enough but he will not get into the Tuneboy. There isn't enough business in this town to make it worthwhile.
Consequently, I don't know squat about how the TuningLink emulator in Tuneboy works or how mapping it manually would work. From these forums, there's only one guy I know of (Hombre) who got someone to dyno tune his bike with Tuneboy - and that took 9 hours.
You appear to be a professional tuner. Are you a DynoJet center? I and I'm sure a lot of folks on this and the other R3 forums would be interested in your experience with dyno-tuning with Tuneboy.
