My dealer says my ECU is fried. What is an ECU? What does it do? Can it be replaced with a power commander( I dont know what these do either) or do I need an O.E.M. part? The ECU is very expensive. I need some good advice. I want to get back on the road A.S.A.P.
The ECU is the main computer needed to run the bike.
Unfortunately the PC is only a piggyback unit. IT would still need replacing.
Expensive but a full termi systm comes with a new ECU I believe.
What year and model of Monster is it?
There are other options for replacements besides the Ducati unit, for some years/models.
I would also get a second opinion. All to often "you need a new ECU" translates to "I don't know what is wrong with your vehicle so it must be the ECU"
I did once have one fried in a car, but it got replaced under warranty.
I'd be interested to see what lead to this conclusion....What exactly is your bike doing?? An ECU just "dying" sounds like it could be part of a bigger (electrical distribution) problem, but hey...I'm not a expert by any means... :-\
If you've recently had a dead battery, and jump started from a running car, you will have fried the ECU. They are very sensitive, and the excessive charging amperage coming from a car's charging system will cook an ECU almost instantly.
Also, if you've had any kind of electrical issues, and have tried using a test lamp/probe to investigate, you may have shorted by incorrectly testing components.
I'm just tossing a few "maybes" out there. If you could provide a bit of history leading up to the ECU failure, then diagnosing additional issues might be found.
If you have a bug in the system somewhere, and it isn't corrected, then you risk blowing another ECU.
DANG! I did try to jump it from a running car. That was an expensive a$$ mistake, at least I learned a lesson. I geuss I will buy a termi set-up since it comes with an ECU. The price is'nt that much more than buying a stock ECU. Will I have to have it mapped or is it pre-programmed?
It is my understanding that it is "plug and play", although if your bike has a TPS, it will have to be reset by the dealer.

Whether he'll need the TPS 'reset' depends which bike he's got.
depending on which bike you have, this might be a good oppritunity to get an alternate ECU such as FIM or Ultimap.
Its an 02 s4. What is a tps? Is it a report that I will need to put a cover sheet on [cheeky]?

Your choices are:
OEM (stock) ECU.
DP ECU, may or may not be a good idea depending on what mods you have on the engine.
FIM/Ultimap U59 ECU. Fully adjustable, not a lot of places can tune them.
I've got one of the FIM U59's on my '02 S4, running a map straight from FIM.
Works great.
You will not need to do a TPS reset for any ECU.
