OK,

    I know you guys with TTS can put a display up to monitor what is
going on.

    Could the Revolution Performance system be tapped to run a Air
Fuel gauge like below to see where the bike is doing, or would it
screw up the Rev Performance stuff???

     Would this be better than putting the bike on a dyno and doing a
AFR run???

Thanks

Another way to skin that cat might be to make a pig tail and piggyback that gauge into the system down by the O2 sensor.  You could buy a single gauge and swap it front to rear if needed.

That is a Ricer Light Show.  They will help quite a bit of lots of things.  They are not an end all solution.

The easiest way to get one of those working is to get a broken XIED from Nightrider and cut that up to make an inline splice that is easy to take in and out of the system.

Dynos are great for getting the motor close enough to get on the data loggers.

Do you want a full-time LED gauge on your ride or do you want to now where to tune your system?  For a little more money the Daytona Sensors WEGO III that will display what's going on and records that data to be downloaded and analyzed on a computer.  This unit can be attached to your o2 sensor, or you can make or buy a "sniffer" unit to use while tuning and take it off when the bike is dialed in.

Here's a good thread on the unit being used:  http://harleytechtalk.com/htt/index.php/topic,26210.msg267218.html#msg267218

I've got the Revolution Performance ECM, I'm doing our break in but
they have not done a bunch of bikes with the 48 cam.  Ours is running
hot, going down the road I feel the heat off the rear cylinder and I'm
running ceramic pipes.

Pulling into our shop my front was 280 degrees taken at the spark
plug with a IR gun, the rear was 320, this was right after pulling into
the shop and putting the gun on her as fast as I could.

So I've got the 02 sensors just was looking at tapping the Rev-Pro
setup to get some real time feedback as to where my bike is.

I called Revrelution Performance and talked to the guy who does
the programming, and it looks like after we get the bike broke in
I've got to go have a dyno run done to get the the AFR so they
can reprogram my ECM.

You can't use the RB Racing AFR gauge because that uses narrow band sensors, the Revolution Performance O2 sensors are wide band.

The RevPerf FAQs state that they 'condition' the signal from their wide band sensors to make the HD ECU think it is seeing the signals from the factory fitted narrow band O2 sensors. If you can get at that signal easily the RB Racing AFR gauge can be used.

You might be better off using the WEGO wide band gauge instead.

I have spent some time on the RB Racing website trying to work out if they are as good as they think they are... I like their explanation of why you need an AFR gauge and how to use it so I ordered one. They are not known for rapid response to orders but 5 weeks after placing the order shipping is 'imminent'!

The Factory ECM accepts signals from Wide Band Sensors units. Just have to change the setting from production level software to development level software. HD has been using them in house on the factory ECM since Delphi came online. It is a simple 0 - 5 vdc input. So yoou can monitor the signal as long as you do not place a load to it.

Thanks Steve, Guys,

   I've no problem with the system, I'm the one who threw a wrench into the
mix with a new Cam.  So either I pay to have a Dyno run done $40 for the AFR,
or I figure a way to read from the 02's I already have in the system.

   I'm figuring that the readings from the 02's would be a lot better than the
exhaust reading on the dyno.  That way I can also check the reprogramming
to make sure the system is right where we want it.

Thanks again.

First I want to start by saying I also have the Rev Perf EMS. Did you change cams after R. P. flashed your ecm ?  Even if you did they say the only time you have to reflash is if you change displacement +/- 20% or change to different injectors or a different throttle body. If you change air filter, cams or exhaust (which I am about to do) all you do is perform the "start-up" procedure again. Now it seems that depending on which cam you use you have to send ecm back for re-calibration, and thats if thay even have a map for that cam. Kind if dis-heartning after the claims they made and the money I spent if this cam thing is true. (Do have cam change plans in the future, the 48 is one my choices).
My bike does run good ,although slight decel pop when shutting down from two different rpm ranges and not getting the gas miliage they claimed. Starting to have some doubts about the system. Please keep us informed on your proggress.

Hey cody,

   This is a fresh build and the Rev-Perf was added during this build, I filled out the
sheet to have the ECM programmed with the setup we have with the 48's.

   I think the problem if there is one is the 48 is so new that the map may have
missed the mark.

   We've got another 200+ mile day to finish breaking in the bike so then we will
get a dyno run and have the AFR checked and go from there.  This will help them
build their data base, it will cost me only $40 to do that run and I will do another a
couple hundred miles down the line to check if we had to reprogram.

You will love the 48's they torque is really there and we are keeping the bike under
3000 rpms for the break in, can't wait to see what she can fully do.

Heck the whole problem could be the rider but I won't know until we can check it out.

Finally...a good use for those XIEDs. :hyst:

We'll we put the bike up on the stand today and went over it.  The exhaust
nuts were loose on the front and the rear, now I gently tightened them after
each heat cycle and then again when we let the bike run 12 min and they were
tight.  So we will see how she runs this week.  I've left the heat shields off so
we can get to the nuts to keep a closer look at them.
