'01 750SS ie fuel system upgrades

I recently replaced the fuel injectors in my seven fiddy. After looking up the OEM parts on Ducati Omaha parts list I suffered immediate sticker shock as the price listed was $482.... each! After some research into the part number and specs of the injectors, I was able to source these as replacements. They were substantially cheaper and work just fine. The price was lower than cleaning the original ones not even considering the 32K miles on them!

I also added a Power Commander III USB to the bike.. According to Dynojet there was never one made for the '01 750. I used one from the M800 I found used and the wiring plugs worked fine. I got a "donated customer map" from the Dynojet archives and zeroed out all the cells to test the function. Test road it yesterday and it worked as advertised with the throttle TPS indicator tracking the throttle movement as required. I turned on the "accelerator pump" function to test in the coming days. If it works,, I'll get to the dyno for a specific tune for it in the future. Right now, it's running better than it has since I've own it!

I'll update this as it progresses.

This post is all win, as far as the eye can see.

I say this as an owner who had to splash out on a new injector not so long ago.
 
My 900ie has now done 53K miles and the injectors are still good, i am sure that they will fail at some point and i will be going down this road but hopefully not soon.
 
I also found this info on the injectors...

the pico injectors work really nicely with the testastretta superbikes once mapped properly.
Their spray pattern and atomising is a lot more refined.

Obviously you wouldn't though as all of this older bike stuff is just old shit that should be in landfill and you should all be remortgaging to buy up the latest factory customer bike offering surely?

Speaking to Rich at Louigi and Chris Steadman, they reported some nice fuelling when they've put them on customer bikes as a result, ok not in the sense of obvious outlandish power gain but the way the whole bike fuels and reacts with the pico injectors. The spray pattern works well with the inlet tract design and the atomisation just serves to enhance and refine what's already there.

Stuart - this is an old thread but it touches on a topic I'm interested in. The conversation started with IW031, then moved on to the later Pico injectors. Are the older IW031 injectors and the IWP-043 dimensionally identical? (O-Ring size and height I'm mainly interested in..)

Regards,
Mike

Hi Mike,

Not sure tbh - ours are 14,7mm OD on the o-ring (fitted) and an overall length of 47.3mm

Thanks.. I *think* I'm running out of injector time on the bimota (which uses IW031) at the very top end of WOT, hence the question. Since asking that question last night though, I've realised that I have a 696 throttle body (and injectors) on the shelf, and an old set of red IW031 injectors somewhere, so should be able to compare directly, without having to tear any bikes apart (y)
 
Well, that answers the question. As soon as I had a close look at the 696 throttle body, it is clearly much smaller.. :)
*edit* - just realised that these are siemens injectors, so slightly different, but the proportions look similar to the IWP-043
