Well I just got my Race ECM yesterday and plugged and played. Great stuff. But... I noticed as I was removing the stock that it had a crack on the top left where the plug meets the housing. I wonder if this had any contribution to my cold idle and running issues??? Anyone else run into this? What did HD do for you? -p | ||

There was a spacer that kept the seat bottom from coming in contact with the ECM or wiring. | ||

Had a cracked housing RH plug, from the seat riding on it. Caused rough running, cutting out intermittently. Did a band-aid fix with zipties and epoxy and used a long carriage bolt sticking out above the ECM to keep the seat away. Fixed the problem for me right now. | ||

Cracked ECM connector here also. I didn't mount my Erik Buell Racing ECM in the stock position, I just put it down in the well in front of the battery. | ||

Mine was touching so when I installed my Erik Buell Racing ecm I spaced the block up a bit more and I have already heated the bottom of the seat pan and bubbled the bottom with a cavity for extra clearance. I put some playdoh on the ecm and there is still only a limited amount of clearance. My theory is that when the bike gets nice and toasty the plastic seat pan becomes flexible and pushes on the ecm connector. As it bounces up and down the intermittent issues or "hot" issues begin. I have had no problems with mine thanks to preventative maintenance found here on Badweb. | ||

I just took my 08 XB12XT in yesterday for a crack ECM. The grey left connector was pulling away from the case. The bike is under warranty, so I am going to get a new ecm. The bike was loosing a cylinder at speed, rough idle and popping. I noticed I could get off the bike and the idle would change, I knew then what was up. As soon as I get it back I am going to move the ecm or machine something to protect it. I would really like to have a extension cord and mount the ecm further up near the tail of the bike. It would be nice to get the ecm away from fan, I am sure the heat does not help anything. | ||

somebody should build these. It took all the seat load off my ECM. I had a local Amish machine shop willing to produce them them for $11.00 each, spray painted. but I don't have the time to deal with all the orders and shipping. http://www.badweatherbikers.com/buell/messages/142 838/517589.html | ||

Rwcfrank : I think too that its the heat that makes the plastic bottom of the seat soft, so it comes into contact with the ECM going over rough roads. The rough running/cutting out problems only happened at 90+ degrees for me. Does anybody make extensions for the ECM cables, so it could be relocated? | ||

Same here on both my 06 and 09 uly's. After chasing my tail on the 06, I moved the ECM and tucked it down the side of the battery. No more worries since then. | ||

Had mine replaced a few weeks ago under warranty, cracked above the plug and down the middle of the connectors. | ||

I had mine replaced on my 07, It was under warranty, within a month of losing it!!! | ||

For those of you that have had cracked ECM connectors, does your front ECM mount bolt have the plastic spacer block? Last time I looked at the bottom of the seat, the only mark I saw was a small one where the spacer block contacts the seat. Why are some people having problems with this and others are not? By the way, I'm no lightweight at 225 lbs dry. Sometimes my wife rides along but I am not allowed to talk about her weight. I think I will take a real close look at my ECM connectors when I get home. I still have some warranty left and would hate to pay for a new ECM. Thanks. | ||

Mine has the block, spaced up with a washer and still hits! | ||

On my 08XT the epoxy bonding material is cracked at the gray connector to ECM body interface. I had the spacer block but it was not enough. I installed an Erik Buell Racing ECM and eliminated the seat problem by adding another 1/4" or so spacer on top of the OEM spacer. I still have 7 months left on my warranty and haven't tried to get HD to replace the ECM. I just don't like the idea of having to make a 120 mile round trip to the dealer, argue with him about the problem and his responsibility to fix it ( replace the ECM), be out of the Uly for a month or so while he jerks around with it and then hitch a ride back when he is done. On top of that I swore that I would never step inside of his shop again! Guess I will have to find another dealer... Husky | ||

Mine has the block but it still hit and cracked. I called the dealer to make sure they had one in stock and took it there and they swapped it out right then. | ||

7000 miles, no issues, no worrying about cracked connectors, no spinning captive nuts.....   | ||

A ECM falls under the emissions warranty,It is separate from the bike. AS TAKEN FROM THE WARRANTY MANUAL: Harley-Davidson Motor Company®/Buell Motor Company® warrants to the first owner and each subsequent owner that this vehicle is designed and built to conform at the time of sale with applicable regulations of the U.S. Federal Environmental Protection Agency at the time of manufacture and that it is free from defects in materials and workmanship which cause his/her motorcycle not to meet U.S. Environmental Protection Agency Standards within 5-years or 18,641 miles (or 30,000 kilometers) whichever occurs first some covered components are as fo;;ows: 49-States “What is covered” Air cleaner and backplate Air cleaner filter (only if due to malfunction of related system that affected the performance of this part) Ignition system – coil, sensor, module, spark plugs (“out of box”), plug wires Carburetor Intake manifold and seals Fuel injection systems; o Cam position sensors o Cylinder head temperature sensor o Barometric sensor o Crank position sensor o Engine temperature sensor o Throttle position sensor o Intake air temperature sensor o Wiring harness of EFI module o Induction Module o Electronic Control Module (ECM) o Idle Speed Control Actuator (ISC) o Engine coolant temperature sensor o Oxygen Sensor o Fuel Injectors o Idle Air Controller (IAC) o Fuel module o Check valve o Fuel Pump (for leaks and/or high and low pressure failures) o Map sensor So therefore if tou are less than 30,000K and 5 years it should be $0.00 retail $352.00 as of now it is available,not backordered.

wheelybueller, this is interesting information. Most stuff on that list is what is failing on 06\07's that are out of warranty by time. | ||

I just looked under my 2008 seat and saw that one of the ECU connectors is rubbing against the seat. I guess I should dremel it away before I kill the ECU. | ||

I took a real close look at my ECM, seat bottom and connectors last night. There is only one small rub mark where the spacer block hits the seat. No marks from the connectors hitting the seat. I did notice that the corner of the spacer block is worn down just slightly though at 5,000 miles. Everything in this area of my 08 XT is stock except the seat, which is a 06 Tall Seat. Even with that, I believe all seat bases are the same on Uly's. What do you suppose is different on some bikes? Manufacturing tolerances on the ECM mount? Thanks. | ||
| Towpro |
Not sure I would cut the seat bottom to accommodate the ECM. That could only weaken the seat base and it could start to crack. For those of you who do not see the connector rubbing the seat (yet). Try the play dough or putty trick and you will see how close it really is. | ||

Got the black block spacer. Good to see I'm not the only one here... And that it's not my fat a$$. $352.oo?????? Only two-fiddy for an Erik Buell Racing race tool... (which is what I already have now) -p | ||

Had cracks develop in the "epoxy filler goop" around the ECM connections May '10. Local HD/Buell replaced the ECM without charge after I pointed them in the direction of looking for cracks. Figured to look for cracks after reading about it here. I am a heavyweight, so I may try to develop a shroud to protect it from the seat or do the "stuff-it" method as Rwven suggests. | ||

Back that photo up a bit Ron??? -p | ||

Well I just spent an hour making sure my seat base was not resting on my ECM. I put a 1/4 inch spacer under the factory black block spacer and it still touched the ecm. I heated and bowed the seat pan some more and I measured about 1/4 clearance while static. This should be sufficient. I encourgae everyone to check this before the ecm cracks. | ||

Timely thread for some  The rub marks seen in the slotted area are from the connector on the ecm. This could be how it is breaking that specific area with weight directly feeding to the ecm socket that protrudes. The other long rub mark to the right is from the chock.  This was my quick fix for now. Hot blade to remove slots and clean up edges, heat gun to area where the chock rubs and pushed in with blunt object.  Side Note: Ordered some Amsoil hoping to have it circulating in time for http://www.richardsonsharleydavidson.com.au/dyno-s hootout-september-2010.html If the weather is kind, i might talk another buell mate into riding over and trying the dyno.  | ||

What's the weights on the cracked ECMs? I'm 100-110Kg (230-245lbs) I also have similar wear scores on the block and seatpan. Called the dealer and they said they'd swap it out. -p | ||
| Balloyd66 |
I'm 250 lb. and it's all right there on the seat. |
