Hey All,
I'm trying to get some feedback on rev limiter settings. With the work I had done it seems to run out of R's fast especially in 1st and 2nd gear while still pulling. It is set at stock now which i think is 5400 RPM. Were should I chip it at? [smiley=nixweiss.gif]
Does this effect durability? Longevity? Warranty???Please DO TELL! [smiley=shocked2.gif] Third gear revved out at 85 MPH at what I think was 5400 RPM! [smiley=confused5.gif]

I have a Zippers ECM and it came set at 6250 I think. I really don't get up in the RPM'S that often. I am still running stock cams. I think they should have set you up a little higher. I would have to go back and look at your dyno sheet. If you run out of power there is no use running the RPM'S higher and make no more power. But if you have some power left they should have set it higher.

BLING I just went back and looked. The dyno ran your bike to around 5700 RPM. I would go back to the tuner. It looked like it was running out of power but the tuner didn't run it far enough so we could see where the power drops off.

The rev limiter is set at 5800 rpm, you cannot change this without the stage 1 download or the race tuner. 6250 is about the most you'll get out of the 103 safely

Or by adding a Power Commander II USB, which is fully tunable to what ever rev limit you preffer

HD dude I went into the Harley Davidson shop in Austin Texas they were clueless about the stage 1 chip. I started at the parts counter and they didnt know what I was talking about. I went to the service department and they told me that it had something to do with the VIN number of the bike and told me mine had the latest and greatest. So then they dicked around with the bike trying to down load some custom maps. I heard them run it up on the dyno a couple of times and they coudnt get the downloads to change the REV limiter. The service manager told me you can only change it with the Race Tuner or with the power commander which as far as I know was going to be released in Marchtober. What ever that means.

I believe I am correct when I say you cannot adjust the rev limiter with a PC. They say they are coming out with a system that will let you do that, but that was 3 months ago and I am still waiting. There is some adjustment with a race tuner. The PC and the RT both have their good and bad points.

It's annoying that we know more about the maintenance and availability of most of the stuff for our bikes than those ostensibly professional in the topic should. The stage I chip for the SEEG is HD part number 32926-03B .

It was announced in some trade press several months back that the PC III USB would soon be capable of adjusting the rev limit. At least so far, however, it's never happened though.

HD I understand what you are saying. I know that is why Zippers set them at 6250. If you have a 2004 or eariler you can set the rpms up. The 2005's need the new power commander (stealth) if not (all you HD techs know this) you can not do anything with the ECM and it will tell any HD tEch that plugs into it the THE WARRANTY ON THIS BIKE HAS BEEN VOIDED.

The 2005 ECM does not like add-ons like the PC or TFI modules, and will set codes if it detects one. The "stealth" deal is a little bit of wizardry built into the newest versions of these devices so that the H-D ECM cannot detect them.

There are two ways to get the calibration (Harley calls the one for the air cleaner and mufflers the "Stage 1 Race" calibration in the SE Pro catalog). The first is to purchase the one-time-useage calibration cartridge and have the dealer load it to the ECM, and the other is to have the dealer hook the bike up to their computer and download the calibration directly.

MAVERICK · « **Reply #16 on:** July 10, 2005, 10:35:34 AM »

Okay GRC the dealer in Austin said I had the latest and greatest since I have a stock SE 2. Next both the parts and service people were clueless about the cartridge. When the service department tried to download a custom map into the bike it didnt work and failed to change the rev limiter setting.Which one do you have and if you have the cartridge where did you get it from?

Maverick, just responded to your PM with the chip part number and a place you can order it from. As with many things at the parts counter or service center in a Harley shop, just because they don't know it doesn't mean it's not there [smiley=nixweiss.gif]

How do you know if you have one of the "stealth Models"?

osmacat · « **Reply #19 on:** July 10, 2005, 11:46:44 AM »

I have noticed that sometimes my bike hits the rev limiter before 6k rpm especially in first gear. Then other times it pulls to 6200. I attribute it to the tachometer calibration accuracy. It is possible that the circuit is rate sensitive as well?

CAT without the stealth models of the TFI and Powercommander your ECM will detect that someone is trying to make changes to the HD map. The race tuner can do it but that is how HD wanted it. They wanted everyone to but a RT from them and not a TFI or PC. The stealth models are out. The power commander will change the rev limit but I went a different route. I purchased a Zippers Thunder Max ECM. With this you remove the factory ECM completely and the Zippers ECM does so much more. If you have a lap top you can make changes your self. I would never change the map without a dyno but you can change your idle and rev limit.

Also I must warn you YOU DO NOT WANT TO REV OVER 6250. Your cams run out of power before that and it is unhealthy for your stock bottom end. I do not know exactally when the se 253 cams run out of power but I think it is around 6100 so going over that would do you no good as far as making power. These are just my thoughts and I am sure that some might disagree and that is fine. That is why we are all here.

I realize this is only hearsay and anecdotal; but the folks at DynoJet told me that all the PC III USB with their part number 807-511 are transparent to our ECMs. Those earlier releases of the unit that are not are supposed to be noticable by the fact that an error code will be there everytime the bike starts up.

DAWG, in my opinion you are right on what you said....an example is JC's dyno sheet...posted under dyno numbers...you can see the drop off. And anybody that tries to re=map their bike without a dyno is taking a big chance. It may seem to run ok but if it is set too lean it can cause problems. I know some people that have experimented in their garage with varying results...some ok, some not. A good Dyno tech is the way to go. I prefer the Race Tuner over the PC. I have heard some good reports on Zippers ECM. I would like to hear more from owners. Just my .02c.

BAGGER go to ZIPPERSPERFORMANCE.COM or call 301-621-2311 and ask for Bill Lamb. You can tell him some DCFIREMAN told you about them. They are great people to deal with. I have known these guys for over 15 years. The Thundermax ECM is so good they were doing installs at both Daytona and Myrtle Beach they would do the map install for your bike put it on and then let you go for a ride. If you liked it you kept it if not they would remove it. Guess what nobody took them off after install. The ECM will take you to another level. You will really like it.

That would explain why hd-dude's and mine never see a trouble light when we start up.
Just glad I bought that Freedom package and got that right P/C.

Now, all I got to figure is how to get hd-dude to install some (nontrouble) lights!

Mine's set at 6500 also as it is a convenient number to use when running on the dyno. From a practical standpoint it's really worthless in that the HP and Torque numbers start to go away at a high velocity at 5800 and there's no need to hit the rev limiter.
