I've heard that the latest SERT + Cali '08 touring ECM combo is severely limited in function and adjustability - if true, is this just poor programming or Big Brother meddling? Waiting to make sure it will work before I buy. I see that S&S has a competitive unit - me likey S&S...

The SERT does just as much in the 08 software as the 07 software if not more.

Well I'm back from the 10 day so called vacation with the wife's family. Lets not go in to that one.
So here is what happened with the 2008 Race Turner for my 2008 Electra Glide. As I said before I could not download the new map to the ECM. Every time I tried it would go to 25% then an error would come up. I knew my cables and computer was ok because I also did a download to my 05 RoadKing using its own race tuner kit.
I had the local HD dealer reboot the ECM ( reloaded stock map ). Then I created a custom map by taking the stage one map file that came with the turner kit that matched my bike and then bumped the mixture up a touch to make it a little richer mixture. Connected the cables did the download with out a hitch.

Jumped on the bike and road for about 30 minutes then sat on the bike in my driveway for 5 minutes. Yes it got a little warm but nothing like before. Oh by the way I also put on the HD wind deflectors ( heat shields ) that install where the set and fuel tank meat.

I'm happy now, my legs not getting cooked are happy now and the performance is great.

Hope this helps others who might run in to the same problem with the download.
Keep the rubber side down

One more thing I forgot to mention. We were unsuccessful in installing the HD SE Tuner Kit in the 08 using a laptop with Windows Vista. I used my son's laptop with Windows XP and no problem at all. I found on a couple of forums that discuss Windows Vista not being compatible with the HD software.

Just a thought to help the next guy out.

Take care Bob C

Has anyone used the SERT on a MM bike? I have an 01 Ultra and was wondering if there were good results with the Magnetti Marelli also? I read the first 10 pages of this thread and didnt come across a coment on it. I also had another question; Does it matter what downloads you already have on the factory ECM before you start with the SERT? What I maen is does it matter whats on there to start with or does the SERT just ignore the factory ECM entirely and then start with its own map? i.e. its not a "piggyback" type thing is it?

The MM injection system isn't a Speed Density system like the Delphi System is so spending the money on a SERT for the MM to me is a waist of money .A Power Commander will work great on the MM and it's a little better in the user friendly area. The PC works with Throttle position and RPM and thats all the MM System works under so it's a good match.

I slightly modified the map #100 for my 08 RG and uploaded it no problem. Bike runs well (it was cool out, so I am waiting for the warm weather to see if there is a difference). Anyway,when uploading it asked if I wanted ACR or not. I toggled yes, but I am not really sure if my bike has this option. I am sure it was asked here before, but I can't find the answer.

Does it matter on the 08 RG?

Thanks

Tom

First off, I'm no wrench so I am only sharing what I think I know. SERT is not a piggyback. You use it to alter the existing map in the ecm. Or you can download a fresh map (several maps come with the software?) and then adjust that fresh one to fine tune it. Either way you are adjusting the map in the ecm when you use the sert. You need a dyno to really get it dialed in good. With enough trial and error and using the data record mode you can also get it pretty close.

Now, someone who really knows can set us straight...

Thanks, I know that. I don't have a service manual yet so what I don't know is if my 08 RG has this feature, as it was toggled OFF in the software. I toggled it ON as I figure if it has it, it should be on, and if it doesn't have it, it shouldn't matter. Just seemed strange that the map I used was for an 08 touring and the ACR was turned off.

So I'm still asking, is it on this model, or does it matter if I have it toggled on and it isn't part of the bikes operation?

The ACR are in the 08 ECM's all you have to do is install the heads that support the ACR and wir them into the harness and then activate them with the SERT....BINGO.....DONE. no pun ment here.

I have been looking a lots of SERT maps and noticed a vertical wall of fuel on some maps and the wall is missing in others. Does anyone know of what caused this wall on some motors and not on others. I think I know whats going on, but it's just a guess. It's always right around 1200 RPM if it is there.

S159PC004-A1.MT6 that is in your SERT ...\Tuning Files\MY2007\ directory is a good example.

If your talking about the value of 14.6 in a red block area, that is where the 02 sensors are on line. The ECM sees 14.6 as a switch not a fuel value, if you change the 14.6 as little as 14.5 the 02 sensor is turned off in that cell. Any map pre 07 except for the 06 Dyna will not have the 14.6 value, some will have 14.5 in the cruise light load area.

No, on the VE map

This graph doesn't show AFR,I don't understand what you mean by wall of fuel....this is a graph of the VE Table.

The VE table is a visual representation of how the engine is breathing ''IF'' the synchronization was done correctly between the AFR Table and the VE Table as it was tuned. If this process wasn't done correctly then this table don't show you nothing worth while. I can look at a VE table and tell you where the cam kicks in, I can see the difference between a Rienheart pipe and a Fat Cat pipe by looking at the VE Table because I know the breathing characteristics of these listed items. I've trained some Harley Techs that actually was taught to take the high peaks of the VE map you have showing and blend them with the low spots of the Map Graph.....this messes up the whole tune and the use of the graph your looking at now.

Doc--so would that "wall" dipicted on whittlebeast's graph be a characteristic of a quick roll off the throttle then?
