AFR "Safe Zone?"

[barbagris]

.... been tempted to buy the optional LCD....... I am glad I didn't bother getting the LCD module as I see it as a safety risk as you would be tempted to be reading and adjusting while on the move.

100% - the only thing is that you could stick it in a bag and simply (I think) log data.

Even my voltmeter switches off if everything is OK. Wish I could do that with the speedo really.

I believe that is another of it's capabilities

Are you prepared to spend 300 bucks to find out though?. I'm not.

Also when it comes to AFR measurement - I have been told that there is a big difference regarding the exactitude of different sensors/controllers. So that (merely to illustrate) 14.5 on a Dobeck AFR and a PCV/AT MAY not be the same. The only real way to know is calibrate it against certified & calibrated sensors. Add the fact that they can drift over time:- so that what is 14.5 today is 14.4 (or 14.6) in a few months.

I have somewhere a set of notes on sensors and controllers/monitors taken from Scott and Wayne Tripp. I'd certainly NOT go leaner than the Triumph load map values. They're set lean to get through emissions controls and if they could have gone leaner - they probably would have.

That's why I made version 2 richer as I found ver' 1 was a tad lean

From what I understand, the AFR+ has a closed loop mode that keeps a given load at a specific value just like AT. I plan on experimenting on that when I get mine in the mail later this week. They took a little longer than expected to get it out to me due to the holiday break.

I have the Dobeck AFR Plus. My bike was the test mule for the Rocket III codes. Mark developed a quick code for it last April and then we tweaked it in late November. Unfortunately it started snowing here in December and we have been iced over until just this week. I have not been abled to ride it much to test out the new code yet. I have to say the device is the way to go. The power, torque and MPG boost are well worth the price. The April code gave me about 19 HP and 10 TQ. I have not dynoed the November code yet. Mark will have the base codes set for you when it comes. However, what is so good is you can set the specific AFR where you want it in 3 different zones and you can set where the switch point for those 3 zones changes occur. All the settings can be changed on the gauge read out with 3 tiny buttons. Set where you want it or change it back to Mark's settings. You can have power or economy, it is up to you.

I just got my AFR+ this week. Haven't had time to install it. I ride to work every day and want a weekend to play with it. I also finally broke down and purchased my own tuneECU cable. I have a 2010 Roadster with jardines and triple K&Ns. What tune are you using? Did mark make a custom tune? What AFRs are you running in the different zones? It would be nice to have a baseline. I understand I'll have to tweak it more for my bike and if I hear someone tell me "nothing is better than a bespoke tune on a dyno" I'm going to curse you silently. I know and I don't want to.

Y

!!!!!!!!!

[URL='http://[/URL] Check this out. In relation to the rocket I would regard the Stoichiometric range as the lean range, and the red header pipe range down to about 16 :1 Stoich is acheived in a lab with perfect octane fuel etc etc. I would normally not comment on this sort of thread, but there is a whole world of danger in some comments here .This is for naturally aspirated bikes only Forced is another whole issue. Safe is good. Hope the link works as I am not used to doing it. Cheers

Good info from NEV

Hi Vinkster,

I don't know if the Triumph ECU codes are interchangeable with a standard and a Roadster. Some of the other forum members have more expertise in that then I do. I'm sure they will respond with info on that.

My bike is a 2006 standard. When I started this process the Triumph code in the ECU was 20226. It is the tune for stock intake/ cat delete and either stock or TORs pipes. When I did my dyno runs here in Idaho in July I found a nice gain of 19 HP and 9 TQ. While I was on the dyno I tried several different configurations in the AFR+ numbers to see what would happen. We went rich and we went lean. Both ways power was lost. I had my 2 Rockets on the dyno for almost 6 hours trying different things. Marks numbers were the best for maximum power output. Since I have TuneECU while on the Dyno I made a few changes to the Triumph tune. I tried the 100% open on the secondaries and found it created a small dip in the power curve down low near the peak torque. I picked 75% open randomly for the secondaries at a few selected lower RPM positions and left the rest open at 100% and that little change gained 3 more HP and 5 more TQ. Then I put in code 20050 but it is the one Wayne Tripp modified for no decal pop or something like that. This tune added another 1 HP and 4 more TQ. Go to Rocket III Performance and find the thread about comparing 2 Rockets with Dobeck Performance and TuneEcu. I have my details there. I posted that on July 28, 2013.

Something everyone needs to know. Mark Dobeck ran my bike on his dyno for 2 days back in April. His numbers set in the AFR+ are dyno tuned. The code he writes is a piggyback to the Triumph code to adjust for optimum fueling. His goal is not to make power, but to make optimum fueling efficiency. The increased power is a by-product of that efficiency. In November Mark had the bike for 3 weeks. He wanted to take his time to refine the code as there were a few spots that needed tweaking. Mostly the April code had a spot just off idle that hesitated for a fraction of a second and then again sometimes from coasting throttle to power on twist. The November code eliminated those problems. Since I have not yet been back to the dyno with the November code I am not sure of the power reading. I can tell you the butt dyno feels fine though.

Hi Vinkster,

Marks numbers were the best for maximum power output.

Bill.

What were Mark's AFR numbers in all zones?

Green, yellow, red, blue-red, blue-yellow?
