I have the PCV with AutoTune AT200 installed and wired according to the blogs by members here (fxstein and Ken mainly)...and for the most part everything is fine but I have one question that I need to have clarified...

On the PCV Throttle Calibration on my bike, the low voltage is like 0.724V and the high is like 1.825V and before reading some of the blog mods and fixes, I was using the DynoJet CLOSED and WOT static calibration procedure which gave the 0 to 100% throttle on that calibration page...

But by entering for instance 0.710V Low and 4.125V High, the throttle position now goes from like 0.6 to 36%...I checked the DIAG address 01, 13 and 14 was it...and it is like 6 and 101 respectively...

Why is the high end need to be around the 0 to 35ish% or in my case, 0.6 to 36%...instead of 0 to 100% throttle???...

Anyone???...

When you open "Calibrate throttle position" you should click the reset button. closed throttle should read exactly as it sites. Blip the throttle to 100% and the 100% should be the new peak value (what ever the actual voltage is).

At that point I would roll the throttle open (quickly - not reving the snot out of the motor) and check to see that the throttle position appears to correspond correctly. e.g. 50% open = 50% tps. WOT = 100% at that point I would not care what the actual voltage reading was as long as 0% = 0 and 100% = 100.

Does that make sense?

the throttle will not go to w.o.t. with the engine not running (only about 35%). you can go into diagnostics mode and are then able to see w.o.t. or just use the values we've found work well which is 0.710v/4.125.

Ken,
So let me see if I understand here...

What you are saying is that will the engine not running but with the ignition key ON, the normal Throttle Calibration of CLOSED (0%) and FULLY OPEN (100%) throttle actually does not open the butterflys 100% and really only opens the butterflys around 35%, so you need to set the o% and 100% using the voltage values like 0.710v and 4.125v, which more represents the true 0% 1nd 100% throttle positions including a true fully open butterfly at 100%???...

I have the voltages set as you recommended and the bike does ride extremely good with a few rough spots which have already shown up on my Trim Tables... I just haven't accepted them yet, as I am analyzing and testing exactly what is going on so that I understand what happens when certain things occur...

The RICH gas smell of course that we were smelling on that in San Pedro is all gone for the most part and as I said, the bike is running good...just a few more things to get clarified by experts like yourself and learning some of the ins/out of all of theses mods that I have done and I feel confident that the bike will be running in the very top notches of the "curve"...

yes, that is true.

you can go into the diagnostics mode where you can open the butterflies to 100% and set the values that way (which should be very close to the numbers i listed).

Ken,
Ok...I thought that was what you were talking about...just wanted to make sure...I am now going to go back to the DIAG and play around in there to see the differences as compared to the Voltage settings that you have recommended as being close...namely the 0.710V and 4.125V...

Truly appreciate your great continued support...

Ken,

When you put the bike in Diagnostic Mode, then go to any of the TPS DIA modes, I don't think you will see TPS voltage. Doesn't the PCV derive its power from the fuel pump? If the Pump isn't powered, the PCV isnt powered. So, I go into the fuel Pump test to prove my point and I see TPS low value. I cannot see the high value because I cannot go WOT if im not in the proper TPS DIA mode. Catch 22.

Im still trying to figure out a way to properly set the TPS low and high values without free reving the snot out of my 20k bike. I will not do that.

OK, what am I not seeing here? And, I need a AutoTune. Got any in stock?

Thanks!

When I connect to PCV with engine off, Should I see a value in the trim table other than zero in all the gears?

Yes, if you had the AutoTune ENABLED and then went out for a ride for more than the time that you had set for the TRIMS to start inputting into the table...then when you get back and connect your PC's PCV Application to the USB cable on the PCV, you should have TRIM VALUES for the throttle position and RPM for every gear that you rode at...now will there be Non-Zeros???...that depends but at YES, you should have at least some Non-Zeros unless your bike id perfectly tunes, which is IMPOSSIBLE or your AutoTune and or PCV are not working correctly...if you constantly get ZEROS in all the cells, you need to recheck your wiring, especially the PUSH-IN wires on the modules...also, you DO have a toggle switch installed right???...when the AutoTune is ENABLED, the toggle switch will select the MAIN MAP in one position and the AutoTune LEARM mode in the other position...or if the AutoTune is DISABLED, then the toggle switch is to select two different fuel maps that you can sned to the PCV...
