ecm required with a slip-on?

[yoursailor05]

What is it that you have to calibrate when you install the race ecm?

 

[BuellPartsGuy]

You have to flash the ECM to the bike and reset the TPS voltage and zero the TPS position

 

[yoursailor05]

are there like instructions with the ecm?

 

[BuellPartsGuy]

It has to be done by the Harley Digital Technician at a dealer or authorized mechanic. There is a certain procedure that has to be done in conjunction with that computer system.

LeFox et al: I need help. I will be getting an Econo Drummer (used) next week. It is also time for my 1000 mile service. If possible I would like to avoid the dealer. I have reread these posts plus several by Kevin of Drummer and I want to do what is best and cheapest and fun for me. I would love to do the service myself and set up the bike properly for the Drummer (and maybe remap stock ecm and add K&N). What do I need to make this happen? My thinking is I would enjoy doing this work, I could buy a TPS reset tool (or use the free one) and save $$ on servicing. Any advice? I tried to search for 1000 mile service in multiple ways, but the searches came up empty.
Thanks!!

I picked up my XB9s with 500 miles on the clock. I got a Jardine CF pipe, "self" air box mod, and then installed the race ECM. By then I was at 1200 miles so I got the TPS reset software and cables. I read the notepad files that came with the VSDT on how to reset the ECM. Changed the oil, and followed the owners manual on what to check and change. What I'm trying to say is that is is not hard to preform maintenance on this bike. Just a bit of research and you can get away with about 90% of all the maintenance yourself. I recommend to keep all of your mods simple by using production parts like the race ECM. With that said, I have not dynoed my bike so I can not compare what the difference is between the stock ECM remapped to your specific application or the race ECM but probably they are similar. I would be willing to bet that the race ECM might be a bit on the lean side with the Jardine pipe but not so much that my XB9 does not ping--even with 89 octane regular pump gas. So, I think you are on the right track by trying to avoid the $$ that the dealers will suck out of you. You probably will not notice that much of a difference between the Race ECM and the drummer vs. Custom mapped ECM/Drummer and with the dyno and software/hardware costs you would be much better off with the race ECM/drummer. I'm sorry to rant on about this stuff, long day + lots of beer = drunken opinions.

pastor...

direkt-link without a dyno is just not possible if you want to do it correctly.
best option there is just fit the race ecm.

although you can probably download tested maps for the drummer, for me that's not good enough when not seeing the difference in result vs the race ecm.
direkt-link for me is setting up you bike perfect so it purs like a kitten en reacts like you want it too. and that's just not possible without a dyno.

try and search for engineers that already did this setup. they will have a map ready to upload and just need 0.5h of dyno time and work to fine-tune it to your settings.
in other words, you'll be out of there with a perfectly running bike for less than 100$

excellant thread this!! i learned so much, THANKS!

that's why i linked you to it

Wow LeFox! This is my first read of this post. VERY thorough explanation and the dyno charts are great. I really appreciate your input on this forum. [up]

Thanks to everyone else that commented on this thread as well, this is a common issue with many opinions and contrasting view points.

Note that if you are or have been linking to this post that the url has changed. I created a new forum for the 1125R and it changed the url path to everything that was in the Firebolt forum. I didn't realize that I changed so many url paths, and I hope Google doesn't hate on Buellxb.com for it.

Just had my bike remapped at the dealer for $95. I have the K&N filter and factory (dicontinued) race exhaust. Lefox is right people! Bike runs cooler, throttle is a quicker response, with out the popping and it idles perfectingly at 1000rpm. All around the bike accelerates and hold a way smoother constant speed on the highway. THanks for all the info BPG & Lefox!

FYI, when I started with ecmspy I ran a few logs on my stock setup then with the slip on Jardine. I wish I had kept the logs for this kind of thing. Stock, the AFR compensation stayed between 99.8 and 102, thats the ecm adding and removing fuel to stay at stoich. Below 100 its removing fuel and above 100 its adding fuel. With the stock air and Jardine it never went under 103 and as high as 109(lean) with a K&N and Jardine it went up to around 118%.

by putting a right side scoop and rapping the header, does this change anything? will it be a issue? i only see good coming from it but more info is always good.

 

[GatorBuell]

less heat around the motor is always a good thing, but it will not fix a problem or reduce the internal temp of the motor due to a lean air fuel ratio.

 

[BurtonXB12R]

So after all this talk, there's no definite answer?
Or a much widely agreed upon answer?

Stock air, stock ECM, jardine slip on= too lean and possible damage?
Stock air, remapped ECM, slip on= best combination?

 

[NewBueller]

Wow, a lot of information on this post.
My girlfriend is getting the jardine slip on put on her XB9SX in a week or two, and was told by the dealer that the remapping would not be needed, "but ride it a little and see".
Guess I will let her know that putting on the jardine slip on she should spend the extra $100 and get it remapped.
She is just looking at a little better sound, she doesn't push it on the bike.

I just picked up a 2009 XB12SS with 7800km on last Thrusday... The only mod is a Jardine exhaust... after reading this post I am a bit concerned about possible engine damage... I have been looking for this bike for a long time and now that I have it I want to take the best care possible. There is no dyno anywhere around here... The bike runs great, but I would not want to chance any engine damage from running it too lean. Any suggestions...
if i try to remap the ecm is there anyway i can backup the current programming incase the bike doesnt run as well, (i have heard of horror stories of buell's running like crap after playing around with settings, and even the dealer cannot bring it back to where it was.)

Anybody have a Dyno run of a gutted stock muffler/ K&N setup? maybe before and after tuning?
