     Xl1200r |
Xb9 - it stems from people knowing that all of the sensors on the bike have the ability to make adjustments on the fly based on what the engine needs. What people don't understand is the limitations of the stock ECM to do this. It can, but only within certain windows and in certain ways. Bear in mind that the technology does exist. I would be curious to see how a bike with a Remus Powerizer would compare to one of these very custom tunings. | ||

Hey Everyone, As Dris mentioned above, GrandStand Designs, has the honor of bringing this pipe to market in the US. I know many of you have already been calling me about pricing. I'm working on it currently. In Europe, Dris is going to be selling the pipe for 761 Euros including the VAT tax. That is approximately $987 USD. I have been working all day to find the most cost effective way to import them so that we can have a similar price here in the US. I'll report back when I can confirm an exact price. Pete | ||

Pete, Buell is coming out with a full race exhaust for aprox $1600. Slip on need to be priced cost effective. | ||
| Mtmansl |
That exhaust looks great. I am glad to see that you have the Dyno posted as well! Matthew | ||
| Jmr1283 |
easy- i thought u tested and posted dyno charts with the stock ecm mapping. | ||
| Zac4mac |
Dris! That's BEAUTIFUL !!! Wish I could afford it. Don't get me wrong, it's a good price, but out of my budget..  Z | ||

Easyrider and Xb9, I think Xl1200r pretty much stated better what I was wondering. No "free lunch" wanted from me but as he said apparently the ECM can adjust for more or less air flow and add fuel or take it away with varying degrees depending on air (oxygen) available due to altitude, temperature, etc. Just not enough to compensate for the amount of extra flow from more open intake and exhaust. With that said as Easyrider explained the set values all across the rpm range would need to be changed to allow for the much extra air flow with each individual change. Understood. I'm still learning as we all seem to be but I am not as knowledgeable as some. What I intended to ask was "if you just slap on an exhaust and K&N filter, will the bike not adjust enough and run way too lean for any benefit and possibly cause overheating or worse"? It seems as though many people just might do this and probably should not. One last thing as Jmr1283 asked of Easyrider. Is the stock ECM test just that, or going to be, a pure stock (last flash)ECM? Will you be able to "see" air/fuel ratios to see if the engine is in fact running leaner? You guys are great and I'm a slow learner so I really appreciate your patience. This is a whole new world of tuning to me. Bob | ||
| Easyrider |
Jmr1283, You are right, I did so many runs This run is with the stock ECM I have: The BLUE line is the race ECM, the red one is my old original no reflash ecm. It runs actually very good on the stock ECM  Here you see the stock ECM (green), No reflash (like above) against the 09 flashed ECM I am remapping at the moment(blue line)  | ||
| Jmr1283 |
easy- with the no reflash ecm and ur exhaust. did u have the bad low rpm riding(surging)and the other bad traits? Im thinkin for people that dont want to adjust fuel for warrenty reasons. they could just have the dealer reflash to the original ecm map. | ||
| Easyrider |
Jmr1283, No, It's with the latest reflash, it runs perfect on the ECM. And I made the movies with it today. I rides good in all gears, only on the dyno I can make a better timing and fuell map for it. ANd it has a bad WOT map inside. | ||
| Boltrider |
Why aren't the tq and hp curves crossing at 5250 rpm? | ||
| Zac4mac |
metric - 5252 is for foot-pounds. | ||

Oops.....I looked right past that part.  (Message edited by boltrider on January 24, 2009) | ||

I like the power #'s so far dris these are the best by far!!!!!!!! But i am not entirely thrilled woth the look but the power outweighs that lol.. BTW- is it just me or does the back of the exhaust look REALLY similar to that of the stock exhaust, kinda like someone chopped up a stock one to shave some weight, took out some baffles for sound and redirected the exit??? Not trying to step on any toes just pointing out something i see.. Thanx Jake | ||
| Easyrider |
Jake, My 1th goal was too make a performance exhaust. My 2nd Goal was the sound. No some screeming pipe but dark and deep with a rumble. My 3th Goal was weight My 4th Goal was No refill material inside My 5th goal was Looks. Whatever happends with the exhaust, performance was the most important issue. | ||
| Bud |
but can you say a little about those front brakes? Hi Mark, those where original for a Xb ( xb 41 front legs ) we recycled theme and made to fit on the 1125..( with triple tree's ) this set is not available any more, Free spirit had made a few for us one off the first fitment trail for a new dual disk setup | ||
| Ridenusa4l |
+1 Easyrider, the 1st goal should ALWAYS be performance JAke | ||
| Jmr1283 |
easy- now u said it was smaller then the stock exhaust, but is urs bigger at any part? grand stand has those lower fairings and belly pan that works with the stock exhaust, so im curious if ur will work with them too. im really thinkin of goin with their fairings. so itll be good to know. Im goin to cut and add a couple things to the fairings but im not planning on enlarging them. thanks josh | ||

I finished today, the RACE ECM for Joe from the UK. He is going to Dragrace with our Exhaust. 151 HP and 129 NM of Torque. 144 HP and 123 NM SAE Corrected The name of the exhaust is Torque Hammer.

| Easyrider |
Josh, I measure it to be sure, and let you know today. It's smaller 2 cm and shorter 6 cm and more ground cleareance (Message edited by easyrider on January 28, 2009) (Message edited by easyrider on January 29, 2009) | ||
| Blazin_buell |
That is definitely the quietest aftermarket offering out there right now and with go numbers to boot . Great job you guys!! | ||

Dris, I talked to Eric Pinson and he no longer has any agreement with D&D so we can throw that pipe in the trash. Question: Antelope Valley is using Direct Link for tuning the stock module so could we get the map you use for tuning? Pinson is limited by AMA/DMG rules to no internal modifications so we are ONLY going to use intake and exhaust modifications for his engine... (of course, will also change shock to Penske and AK-20 modified forks - but that is another story) | ||

Good interview with Haugo and Pinson at Laguna last year: http://www.onthethrottle.tv/pages/page/laguna_47_h augo_pinson/140_660_1462 Pinson will be riding the R1 AND the 1125R this year. (and I'm just a tuning "love slave") | ||

n00b alert! n00b alert! n00b alert! n00b alert! Guys, can someone help me understand those charts? Of course, even though I don't speak German, I recognize "hp" and "rpm." And I got the part in easyrider's post about comparing the stock ECM to the race ECM and 09 reflash, respectively. I think I understand all that. What I don't understand (but want to) is why TWO lines (solid and crosshatched) for each ECM? And what am I looking for, other than, I presume, more hp along the rpm range? For example, is too much variation along the line (a la the 09 reflash under 3500 rpm) a bad thing? | ||
| Fresnobuell |
Dunno about the others here, but I would me more interested in stock ECM (with no tuning) figures. Nice figures, but the race ecm doesn't apply to the majority here. (Message edited by fresnobuell on January 28, 2009) | ||
| Slaughter |
Horsepower scale is on Left, Torque scale on right. The units for torque have been left in Newton x Meters (Nm) so you'd have to convert the torque to ft x lbs Solid line is HP (corrected to SAE units) - the X-hatched line is torque. | ||
| 1125rz |
dris,any eta on shipment of pipes to pete at grandstand designs? | ||
| Marcodesade |
Thanks, Slaughter. Didn't think to look to the right of the graph for an additional scale. Now it makes a lot of sense. And, it kind of answers some of the questions I had before (bigger is better, significant dips along the curve are probably bad, etc.). Just one more question (keeping in mind I know nothing): what accounts those significant dropoffs, in both torque and horsepower, WELL BEFORE the redline (10.5K) in most of the graphs with stock ECM? In some cases, the decline begins before 10K. | ||
| Easyrider |
1125rz, We are working on a hard shipping date. I hope when i get feedback from the welding company this week, to tell Pete and post the date here. | ||
| Easyrider |
Here is our scheduale for the first shipment to Grandstand Design: Worst case: end week 8 Best case: end week 7 |
