Rednectum: I'll be calling you hopefully early spring to do some cams and pushrods. Bike got here yesturday having Highflow, SERT, and D$D Fatcat installed with tune. Need alittle time to recover from the rapid flow of funds this week.

[rednectum]

call me sooner than that! lets talk some chit. nice pipe selection BTW.

[Shovelhead Bob]

Just patiently (yeah right) waiting on my SERK. Have the SERT at the stealer waiting also. Talked with the tuner he says that after the High flow, pipe, and SERT he will turn off the closed loop mode with the SERT and set the A/F ratio at 13.8 max. How much of a difference is 13.8 (Open Loop as suggested by your tuner) to 14(Closed loop mode with CLB table at 798mVDC)Sound good ? He says that is what H.D. recommends for these engines. Ask the Tuner who or where he is referencing this...What do you'll think cause I B LOST on this one. Thanks

When anyone tells you that they will set your bike at a flat AFR like that, you are reverting in tuning accuracy.... Open Loop mode... vice Closed Loop

Now the tuner is stating that NO MATTER WHAT, the bike will be programmed to operate at this 13.8, providing that the VE's have all been corrected accurately.... There is no room for any anomolies like poor fuel quality, small intake leak, small exhaust leak, dirty air filter or a leaky injector....

Now, with the Closed Loop mode active, the bike is programmed to operate at about 14:1 (Again, providing that the VE's are dead on).... and the o2 sensors are feeding the o2 integrators constant data about what each cylinder is generating as far as an observed AFR, and making those corrections rather quickly. It is also compensating for different grades and qualities of fuel, minor leaks in the intake tract, air filter restrictions and even a weeping injector...

It's your bike, and your choice of tuner... I am just attempting to create the awareness of setting your bike to operate in Open Loop...

Me, I'd never set up a bike that way... Too many enviromental/mechanical variables that will play into the future of the tuning and rideability factor...

Hey Bob, thanks for chiming in on this.

I was a little more than disappointed when I found my map was not available from the tuner, they had an excuse in my opinion.

In your opinion, would the expense of a wide band o2 sensor avail itself to sert tuning on these dinosaurs?  Thanks for input, it is well received.  I do not have the savvy(yet) but am open to learning.

Hey Bob, thanks for chiming in on this.

I was a little more than disappointed when I found my map was not available from the tuner, they had an excuse in my opinion. My feelings... You paid for it, it's yours... But myself and where I work are far from the average bear...

In your opinion, would the expense of a wide band o2 sensor avail itself to sert tuning on these dinosaurs?  The ONLY way to impliment a FULL TIME Wide band sensor is via the T-Max w/AutoTune... To impliment it in the tuning process, you need to use the Daytona Twin Scan II... It will show you the corrections needed to correct and validate the VE tables....Thanks for input, it is well received.  I do not have the savvy(yet) but am open to learning.

Read the manual about 10 times... Then when you think that you got it... read it again.... Me, I am lucky, I get the use of a dyno, 2 AFR meters and 2 computers to dial it in... That is the easy way...

check out the dynojet wideband commander. versatile tool to help with buttmeter tuning!

Red,

I had looked at that one but went with 2the Daytona Sensors Twin Scan II+. The Twin Scan gives you two O2 sensors where the wideband commander only gives you one.

Couple this with a "Road Dyno" and you've got the best set up you can get without having your own dyno.

[rednectum]

chief, you are right! the twinscanII plus is the way to go and does more than the WB commander. thats what i get for typing before coffee!

for those with no bungs,-----WBC can be fitted to a tube to probe the end of exhaust(s).

Well there is alot to think about with setting up my ride. The most important thing to me for now is helping it keep cooler. Hopefully as times go by I'll have enough info to purchase the right pieces to really let it shine. I am just starting too learn about all this stuff. The only modified bike I've had was my streetgilde and it felt good to me. I'm starting much higher with this so im sure I'll be happy for a short time. This site is great and filled with information and good people. When I pick up the bike next week we'll see how it runs and go from there.  THANKS EVERYONE !!!
