So while we are visiting the ignition module thing: (As far as 99 and later M2s are concerned) 1) We have the stock module (which starts to retard the timing at around 6200 rpm and then drops off the face of the map at 6800 rpm) 2) the race module (32680-96Y)(which changes the advance curves and does not start to retard the timing and lets you have everything up to the 6800 rpm fall off) 3) Now you have an '01 M2 module (91438-01Y) which changes what? This can get somewhat confusing for us M2 owners.... loki | ||

PPiA: Same number, 12SVN2R2R. The popping on decel was REALLY noticeable. I've looked closely at the data this morning and there is no difference in the results, they neither helped nor hurt the power. Paul: sorry, I don't know any details of the stock or race kit module curves. All I know is that a well placed source told me "the modules have basically identical curves up to 6200 RPM". The results seem to bear that out. Side note: I spent 3 hours on the dyno doing these tests, and did a total of 59 pulls. Lots of timing settings and double checking results. There was a 40 degree temp difference since the last time I tuned this bike and 2 sizes bigger on the main was worth 5hp. I did that before I started all the testing. Max power with the Torquemasters was achieved at the same jetting as max power with the 10R12's. I didn't fiddle with the timing while the Torquemasters were installed, and I was using the race kit module with it's optimum timing setting as determined with the 10R12's. I think a thorough test of the Torquemasters would've included timing optimization, and that's why I'm a little reluctant to post any charts or strongly declare any result. Anyone want to send me some of these hot-dog plug wires for testing? I'm not willing to buy them, I'm too skeptical, but I will spring for the dyno time to satisfy my curiousity. See ya, AW | ||

Loki : are you reading that of the dyno chart above ? Rocket in England | ||
| Paul Batts (Xlwp) |
Aaron, I would like to send the wires for testing, that is a very generous offer and I'm sure I'm not the only one that would be interested in seeing the results. Unfortunately, I'm not sure you could make use of mine. They are kind of short.  See what I mean? If you think you can make 'em work, I'll send 'em. PB | ||
| Bryan T Nill (Loki) |
Rocket, just trying to balance all the info overload. The numbers are rough as to all the different ones being mentioned. I was not trying to be exact just in the ball park. I was more interested in the fact that the 01 Cyclone has its own ignition upgrade. loki btw: like your ride. Just not into the shiny nickel/chrome thing anymore. | ||

Paul B, What's that under the frame between the coils? Is that an air shifter? PPiA | ||
| Paul Batts (Xlwp) |
Peter, Yes, air shifter. PB | ||

Paul, More pics please. On the correct topic, of course.. | ||

Dave, The correct topic being racin'? | ||

Has anyone got to check their gas mileage after installing a race PCM onto their bike, (of course with using a V&H - Suppertrapp - Borla, etc.) Reason I'm asking is because my '99 S3 gets NO LESS than 50 mpg. with the stock module, stock muffler and a K&N air cleaner. I do plan on putting on the Super IDS this winter. If the mileage you people tell me does indeed drop a lot, well then I will have a brand new race PCM for sale. (I'll take the mileage over 1 or 2 hp) ps. the bike has over 10,000 miles on it. comments? | ||
| Eeeeek |
Ricky, I found that after putting the Race ECM in my bike, the MPG increased as well as the performance. I get below 50 when I'm hammering it through the twisties (worse I've gotten was about 40); however, on the freeway cruising at 80 mph I get 52 mpg. So not only does the EPA stuff reduce your power, it reduces your fuel economy, too. Huh. Vik | ||
| Ricky |
Eeeeek, this is good info. How about anyone elses point of view? Rick | ||
| Fastback69 |
Paul, Is that a single-fire system? I remember seeing some posts about them but can't remember specifics. | ||
| Xlwp |
Fastback, Yes, I do run single fire, however, the VThunder module is capable of single or dual fire. PB | ||
| Fastback69 |
X1wp, What differences have you noticed between the single and dual fire systems? Is there a difference in sound or vibes? Did you gain power? | ||
| Xlwp |
Fastback69, I really can't say a lot, with any hard evidence, about the "performance" differences between single fire and dual fire. I've never done a comparison on the dyno or by seat of the pants of the two. The only dyno I've ever had the S1W on is a drag strip. It does fairly well. The single fire is, however, just part of a total package that seems to work for me. Single fire just plain makes sense to me. I can tell you this, my '77 kick only Ironhead has a Dyna single fire system and it is a one kick motorcycle. Anyone who has ever kicked a Sportster (I weigh 135 lbs.) can relate. Aaron or Pammy or someone else can probably comment on this with dyno numbers to back it up. XLWP | ||
| Xlwp |
Fastback69, One thing I might add, with the single fire I don't have a problem of "kick back" during starting. PB | ||
| Jmartz |
Yes you do. With only one cam sensor plate single fire units start in dual fire mode. | ||
| Xlwp |
Jmartz, I don't PB | ||

My 7 month old battery has died. It was one of the last ones left for the S1 of the original design. Here comes the Blast adaptation...! Has anybody relocated the voltage regulator to the M2/S3 location in front of the motor? Jose | ||
| Tripper |
Jose - you'll like the new batt. No more clicky clack I can't turn that. Just click boom potato potato. After 5 weeks in the garage my battery cranked the motor for several minutes while it waited for me to turn the petcock to reserve.  | ||
| Stoner |
Is the Buell race ignition module compatible with an aftermarket single fire coil? I am considering the Screaming Eagle or Crane, any recommendations? | ||
| Jmartz |
Stoner: You can only fire singly with an aftermarket module that has 2 wires to the coil(s). | ||
| Stoner |
OK. Thanks Jmartz. | ||
| Drandall |
Single-fire Buells: Youse guys probably know this, but the fuellie-Buells are all single-fire (says in workshop manual). David '00 X1-RS | ||
| Rickie |
Stoner asked, “Is the Buell race ignition module compatible with an aftermarket single fire coil?” Actually the answer to that question is yes regardless whether it is a single or dual fire ignition module. However, if you use single fire coils with a dual fire module, you will need to wire individual coils parallel or install a jumper wire on the ignition posts of a siamese (three post Crane style) unit. This will make a single fire coil work with a dual fire ignition in a DUAL FIRE MODE. Rickie | ||

Ok I'll sound like a dumb a$$ and ask the question on the board, because no one I ask seems to know. What is the differance between a single fire and a dual fire ignition? | ||
| Peter |
Single fire means each plug fires as required, dual fire means both fire together even though one of them doesn't need to, and is wasted. Why do they do it? Because it only needs one pickup and one coil with two leads from it, so it's cheaper. PPiA | ||
| Jiml |
Okay all of this talk of single-fire ignition has me thinking of converting my 96 S1 over. So what's everyone's choice's for this? I see where Dyna has the Twin Fire II Coil out now which would allow two coils to be in the same space as the stock coil. That would make it nice. I would think that the Dyna S would be a good system. Just jump in and let me know what ya think. thanks, jiml 96S1 99S3 | ||

Jim: FWIW ... I have a Dyna 2000 on my wife's FXR ... set up for single fire. I've dyno'ed it back to back in single & dual fire modes and couldn't see a difference. Someday I'll do a more careful test, but if there is a difference in power, my initial impression is that it's down in the noise. The ability to set the timing individually for the 2 cyls could be valuable, particularly on a hi compression motor running on the ragged edge, i.e. a race motor. Also, I've heard folks say single fire reduces vibration, but I sure can't tell. YMMV of course. AW |
