Good news Bob.

 

this the one? Wurk truk getting set to v tune

@Steve Cole: I have made an article on my forum about the mt8 files.
http://g-homeserver.com/harley-davidson/119-harley-efi-19-tts-mastertune-1-7-600rpm-leerlauf-nockenwellen-mt8.html

What I really do not understand is the EGR Effect Table. What is it used for? How does it work?

Another question: would it be possible to use the level44 files on a ´08 DBW Touring bike?

I tried to set the Idle RPM to 750rpm, but after a short while I get P0505 error.

Thanks for your help.

[Steve Cole]

P0505 just tells you that it could not control the idle speed. I would check for intake leaks as a place to start. I have my 103 @ 800 and it idles fine there with no codes. The EGR tables are covered in section 3.13 of the Tuning Guide. Lvl 44 will not work on a 2008 or 2009.

[viczena]

Thank you for your answer. My bike also idles perfectly with 800 rpm. The error code will appear after idling for some minutes under 750rpm.

And i read (and reread) the manual for the egr table. I just do not get a clue how this is working. Is there any more documentation?

Thanks.

[Spiderman]

ok guys let it go. you are obviously never going to agree with each other

Just an observation and with no dog in this fight at all. I do not know who Stve Cole is, what he does, who he's talking about, who's right, who's wrong and don't really know an effin thing about any of it. What I do know is every thread Mr Cole has ever posted on has turned into a smackdown. Why is that ? People join this website to learn about their Harley-Davidson motorcycles (mostly) and I truly believe most are open minded. I have had a couple go rounds with Mr Cole on this forum and another simply because I dared to ask questions. And still I have nothing against the guy. I truly don't. Hell Picasso was somewhat of an oddball and Van Gogh - - fugedaboutit so hell the guy might be an eccentric genius. I just wish he could speak plainly and clearly and leave the smackdown attitude for the WWF. We might all actually learn a few things from him if he did.

The error is from the idle not staying in specification over a period of time. Clear the code then try to do a datalog with DataMaster while the bike idles before it sets the code and when the light comes on stop the recording. Send me the file and I will see if I can figure it out for you.

EGR is Exhaust Gas Recirculation all engines have it in one form or another. When the valves are both open the exhaust gas get pushed back in the intake manifold. So now you have a mass of exhaust gas taking the place of O2 in the intake and we need to tell the ECM how much there is. This is what the tables adjust. If you look in the tuning guide you can see the effects of doing nothing more than adjusting the EGR Effect table and how the VE table needs to change from those changes. The idea is to get the VE tables as flat as possible in the area that the EGR effects it. This will give a smoother running engine and one that develops more torque at part throttle areas.

[viczena]

Thank you. Now I understand a little bit more.

But what are the values in the EGR Table? Percentages? Absolute Values? Factors (most probably)?

It seems to me the lower theses factors are, the smoother the map becomes. Why?

What are they doing with the map?

And: How can I manipulate them to get which result? How do I know How far and in which direction I have to change them. How do I see the effect?

The VE Tables are not directly changed, as far as I see...

By a short review I found out that there are (at least) 3 different EGR Tables (front) in use. I name them after the first number: 2.001 (which is used in all of the latest maps), 1.656 and 1.484(this one is used in your example as result of a certain calculation). It seems that these tables are constant within a group of Maps (e.g. "2008-2009 DBW touring Closed Loop"). Why did you change them? what is the really different characteristic between these groups, as exhaust or inlet or the engine itself did not change very dramatically? Different Cams?

The 1.484 EGR and the 1.656 EGR are used for nearly equal engines:

You use 1.484 (CAE176-03-A0.mt8) for "Application: 2007-2011 'All Market' Shotgun / Shorty Dual Exhaust with O2 Sensors, Configuration:  1580 A/C only, Build Components:-- A/C and Breather Kit".

The 1.656 is for (CAA176-03-A0.MT8): "Application: 2007-2010 2 into 1 Exhaust with O2 Sensors, Configuration: 1580 Stage 2, Components:
-- 25 deg Injectors, -- A/C and Breather Kit-- .550" Lift 211/235 Duration Camshaft-- RB Racing 2 into 1 Exhaust"

Does it mean: the hotter the engine, the bigger the numbers? Or the more gas reversion by open exhaust, the lower the number(more probable)?

And  how does the effect of the EGR vary with MAP kPa? (I understand it technically, but how does it work together with the VE-Table)?

Your obversations aren't anything new,,,(in fact quite old when you think about it)  I'm just glad this forum has been spared (for the most part) the 'bias' rift raft up roars common in another... Good job being done over here     With that said, I'll duck with ya. 

[Steve Cole]

EGR effect comes from a combination of parts being used. Each and ever one can be different. There is no answer to what your asking as in do this and you will get this result. You have to test, change, retest and look at the result. By lowering the EGR Effect values you will lower the VE value for the area changed. As stated in the manual you are looking to get the flatest VE table as possible. This will get you the smoothest running, best fuel economy, highest torque producing engine in the part throttle areas, where you ride 90% of the time. At WOT you may see slight changes but not much as EGR does not affect anything much above 60 kPa.

Steve,
In a previous post you said "The EGR tables are covered in section 3.13 of the Tuning Guide. Lvl 44 will not work on a 2008 or 2009." The lastest version of the Tuning Guide I have is ver 1.28. If a newer version was included with the latest update I can't find it. Where do I go to download the newer guide?

I just took the update and I have revision 1.30.

[Steve Cole]

Just the TTS updater will get you the newest stuff. Sometimes the icon's do not update properly on the desktop and you will end up with the old one plus a new one so make sure that did not happen to you. The tuning guide is currently Rev. 1.30 dated March 29,2011, Calibration listing is Rev 3.4 April 5, 2011, and the Tech Bulletins is Rev 1.03 Aug 16, 2010

Got it, thanks.
