Title: Fried ECU? Post by: wllgmr on May 20, 2008, 04:32:09 PM 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.

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. Title: Re: Fried ECU? Post by: Speeddog on May 20, 2008, 06:10:53 PM What year and model of Monster is it?
There are other options for replacements besides the Ducati unit, for some years/models. Title: Re: Fried ECU? Post by: Howie on May 20, 2008, 07:23:42 PM 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"

Title: Re: Fried ECU? Post by: johnster on May 21, 2008, 07:08:41 AM 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... :-\
Title: Re: Fried ECU? Post by: duckwrench13 on May 21, 2008, 01:01:58 PM 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. Title: Re: Fried ECU? Post by: wllgmr on May 22, 2008, 02:14:13 PM 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?
Title: Re: Fried ECU? Post by: rockaduc on May 22, 2008, 02:23:56 PM 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.
Title: Re: Fried ECU? Post by: Speeddog on May 22, 2008, 02:26:41 PM 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. Title: Re: Fried ECU? Post by: He Man on May 22, 2008, 02:42:55 PM depending on which bike you have, this might be a good oppritunity to get an alternate ECU such as FIM or Ultimap.
Title: Re: Fried ECU? Post by: wllgmr on May 23, 2008, 12:58:20 PM Its an 02 s4. What is a tps? Is it a report that I will need to put a cover sheet on [cheeky]?

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. |
