OFFICIAL: Closed Loop ECU modification thread - Ducati Monster Forums: Ducati Monster Motorcycle Forum

CDawg · 07-26-2007, 02:04 PM

- The interest to fine tune one's ECU (post-exhaust and/or airbox mod) is extremely high and there are numerous posts.
  
  I'd like to use this post to pull together all the different options and current product developments and provide a unified thread of making closed looped ECU bikes run better. I will add likes to other threads as I have time. Please feel free to post links on this topic that I've missed. Also please post errors and such and I will append this post from time to time to keep it fresh.
  
  Thanks!
  
  Common perceptions (feel free to add or critique if you disagree):
  - Ducati's come lean from the manufacturer to pass emissions.
  - Upgrading to aftermarket Slip-on's do not require ECU mod.
  - Upgrading to aftermarket full-exhausts might not require ECU mod depending on new exhaust flow rate. For example, Exbox doesn't require ECU mods, but others' may
  - Upgrading to aftermarket full-exhausts and airbox mods require ECU mod to rich the AF mixture
  - No idea if just modifying the airbox requires ECU mod
  Current (and near-production) ECU mods
  - Ducati Performance ECU - Designed specifically for the Termi system, but works reasonable well for other systems. The part number is either "96517706B" or "96517906B". Some dealers will not sell only the chip (without the exhaust and airfilter). Price is in the $1000-$1300 range. Product is not 'tunable', other than the trim. Mechanics for this product widely available.
  - PowerCommander III - Product does not work on closed loop system due to O2 sensor and stepper motor. However, PC III has been reported to work well in conjunction with the DP ECU, O2 sensor removed, and custom mapped. Dynotuners for this product widely available.
  - UltiMap59 - Product is full ECU replacement and will eliminate the need for an O2 sensor while not triggering the "Check Engine" light. Product does not work with stepper motor to smooth out engine while idling. Currently beta testing a unit that runs with the stepper motor and awaiting extra customer feedback before listing on their site. Upshot is the ability to use any aftermarket speedo/tach display. Dynotuners for this product limited in US.
  - RapidBike 3 - Mixed results. Some people love it. Other people says the support is bad and it fried their ECU. Latest from RapidBike is that their piggyback unit used in conjunction with the O2 eliminator works very well. However, the O2 eliminator only works with their system.
    Note: Rapid Bike redesigned the O2 eliminator this winter for 2007-2008 bikes. New O2 module now shipping and is able to add or subtract fuel across the board by twisting the plug to new settings.
    
    Also, it has been suggested to mount the RB module and O2 simulator, far away from heat. If it gets overheated you might not be able to restart it (spinning but no fire)...after it cools off, it's perfect. Please also note that this heat problem was reported on a MV312R '07 E3 and not a Monster.
    Unclear how how the product works with the stepper motor. Need more user feedback. Unclear on availability of Dynotuners for this product.
  - Techlusion TFI Fuel Injection Module - Suppose to work for all Ducati modes by adding fuel across the board in 3 RPM zones. Need user feedback.
  - FactoryPro' Teka Box - Product is in development. Have already been fitted to 3 bikes with good feedback. Currently only available out of FactoryPro's shop in N.California (you lucks dogs!), but may be able to ship product in 6 month to shops that use their Dyno systems. The box eliminates the O2 sensor while maintaining the stepper motor. Dynotuners for this product limited in US. [editorial:[i]could be the holy grail!
  - Competition Systems' Nemesis - Aftermarket replacement ECU for the 749/999/1098. Application for other Ducati's in the works, but no current product for the Monster
  - Jefferies MyECU - Aftermarket replacement ECU from Australia. Website suggests it is a new company with 1 employee. Website has customer testimonials, but no before&after dynomaps. Need user feedback. Does not work with Monsters after 2003, which has a newer two connector ECU

  If desired, one may be able to unplug the stepper motor and set idle the old-fashioned way
  
  Let me know if I missed any or am wrong about anything!

Possible corrections/clarifications:

DP ECU; is not 'tunable', other than the trim.

Ultimap U59; I'm pretty sure they are working on a unit to run with the stepper motor.

All units; I think that if you do the proper procedure, you can unplug the stepper motor and set idle the old-fashioned way.

These need to be checked for accuracy....

Thanks! I've incorporated your comments. [thumbsup]

From what I understand you can trim the stock ecu with the Full Arrow exhaust to play nice, but there is some slight popping.

Does anyone have a full exhaust (Arrow, Zard), open airbox box, and stock ecu? I'm sure there would be some dips in the powerband, But it would let us know how flexible the ecu triming is.

I personally refuse to by a DP ecu for 1100 bucks when it costs ducati 5 bucks to make and flash. I wouldn't recommend buying it from ducati either because then they will just keep kicking us in the gonads.

Full arrows, oem ecu, oem lid. I have a bit of popping @ 3-5k rpm. Going to run my open lid to see what happens. Wanting to avoid pcIII on the 4v. Had one on the 2v. Cost too damn much to set it up correctly.

What I can tell "official" is : there are no problems with RB, none (in fact right now there is a bike with some problems but not RB related and we work on that). I'm not talking only on Ducatis, other then that I saw many "suppositions"...I like that "OFFICIAL" part.

The story of an 07 S4R with full Zard system with the standard ECU and then the DP ECU & Open Airbox.... [thumbsup]

Amazing set up and runs life a real one.... Love it.... (and yes the DP ECU was expensive but I get to keep my warranty.. ;D)
