Ever Used A Ducati Performance Ecu In Your Ie?

They are rare and when they do come up expensive. I put a pc3 on my bike with a factory map. It runs better but rubbish on low revs neutral throttle.
The original ecu can be rewritten which might be cheaper. Mark White at bsd has played with them on a dyno.

 

They are indeed rare. Thing is that back when they were current tech, the stock ECU had enough "slack" in it to be able to trim the fuelling to work pretty well. Many 900's run open cans etc. on the stock ECU reasonably well.
The DP unit ran a little better and iirc had a slightly higher rev limiter, although I may be wrong on that.
Due to the rarity, I've rexxer mapped a few lately that have the now again available Termis from Ducati, minus the DP ECU....

 

The y2000 ecu will work fine on your 1999. Same spec motor.

@nelly is the rexxer map a custom map that you've written for 900ie or dp cans/k+n?
Cheers, Keith.

 

The Rexxer map I've used Keith has been their stock one they've done for open cans and air filter. Has worked pretty well. Smoother, better mid range and around +4hp peak. Tbh, their maps usually do until you start with cams or big bore kits. Then I write bespoke.
When I get mine sorted I'll do that. It's on a FIM flash that was done when the heads went on many moons ago.

 

I think early monster ie had different cams so the dp ecu may differ but will be within fueling tollerance anyway. I have some pics of dp ecu's from ebay. I'll dig them out. I ran cans only with std ecu and it ran well with no probs. When I put k+n and cut the airbox lid it ran a bit sick. I don't think the dp ecu are worth the money they fetch, I wouldnt pay more than a secondhand pc3 which can be tuned on a dyno for a much better result. That series of ecu were a bit under developed imho, my 907ie 10 yrs older runs sweeter than the SS.

 

The numbers are very confusing.

 

Those were in usa. Theres one in uk for sale about £200. What have you done cans filter? Check with nelly first he might be able to flash your ecu to same map.

For monster.

I wouldnt get one from usa. Expensive to post back if its nfg

 

Im pretty sure mine started running rough when i cut the airbox. If you cut yours make sure the front of the tank covers the hole.

 

I think it will work fine especially as you dont have fully open cans. I dont think you're going gain much though and it might even run worse round town. From my experience and a few owners Ive spoken to these bikes are lumpy and vibey and theres not much can be done about it.

 

Pretty sure I have a DP ECU kicking around at home. I must have had it 10 or more years, and it's been sat in a drawer. Will take a look at the part number(s) on it when I get home...

 

The unit I have says 09147A.
