Title: 750ie fuel mod woes
Post by: redial on May 04, 2010, 03:55:41 AM
Hey guys,

Need some input:
After tearing my bike down and back up last week i have decided that the airbox must go.
It is not because i want to open the space up, or free up hp its just
because i refuse to ever, ever have to reinstall that thing again.

as the title says i have a 2002 750ie which is the start of my problem.
I have DP pipes (giacamoto (sp?)) and pulling the airbox in favor of pods will require
some fuel management.

I went to purchase a power card to find with dissapointment that there is not a fitment for my bike
There is however one for a 750ss which just plain irritates me.

the power commander also does not come for the m750 but i know i can have my dyno guy
do a custom map. The question is: do they all wire up the same? if they do, why is there "no fitment" for my m750 with the power card when its just a simple plus and minus fuel set up. IF they wire the same all i should have to do is plug and plus, no?

- My third option i went to is Techlusion which ive read good things about on this board. As the cheapest they are surely tempting, but the fitment says "1994-2004" 750 which makes no sense bc IIRC they didnt make the m750 in fuel injection until 2002 (i think the SS in 2000?) and they only made it that one year, moving to the 800 in 2003.

Furthermore, if the SS and the m750 wire up the same then why the hell cant i use a power card fit for a 2002 750ss????

Help!
Im really looking for one guy to say, heres what i got  on my 750 ie, it works, and it wires up
either exactly as the instructions say, or differently and this is how you have to modify the install

I know you guys are just a mass of knowledge and i know someone can help me, so thanks in advance

-redial

p.s. anyone have a good link for pods? not looking for anything fancy, and id rather not dump $250 on the TPO kit with velocity stacks

AFIAK, Power Commander has no canned maps for you bike, therefore no listing.  I believe a PC for any 750 with a 5.9 computer w[ll work with a custom map.

thank you for the response howie,
do you know of any thread or other resource that lists which
computers are on which bikes? so that i may try to match up a different bike
with the same computer?


Its unfortunate that my need for a $200 richening device has turned into
a $600 PC and dyno tune. i feel like i boned myself by getting a bike only made for one year
i suppose in the long run the PC is the way to go, but this is just my around town bike, if i ever
want to get crazy id just get a sbk or a SR bike to tune around with :(

If I were looking at a $600 bill, I'd save another $400 and swap in a 900 ;)

I can tell you for sure that the 900 monsters and 900ss' are wired differently.

I suspect the 750's would be the same . . er different.  you know what i mean ;)

haha i definitely feel where you are coming from

unfortunately for me, swapping in a 900 would not relieve my fuel problem, so im up to at least 1200
and on top of that, i do not believe the 900 was made with FI (if it was for a year, the motors dont come up for sale often)

so thats a motor plus carbs plus a jet kit >< at that point i might as well just trade up
(which i havent ruled out yet, but i wont sell until the bike is complete)

of course 900's came with fuel injection (started in 2000 on the monsters and 99 on the ss's i think)

you could always swap to a 750ss ecu and wiring harness and then run a power commander with that.

But didnt the 900 turn into the s4 in 2001 making it a one year motor or did they get produced side by side?

No one runs a Techlusion?
Interested if it just intercepts the fuel wire, therefore being basically universal?
thats what i need, just dont know enough to want to buy something and try to force it

I believe side by side, but I may be out on a limb here. . .

If you don't want to spend the money you could opt for the "cheap fix'', which means having someone with the equipment set the CO trim richer.  This will fix idle and deceleration, but the effect will diminish as RPM and load increase so you will still be lean top end.  I do know people have used PCs on '02 750 Monsters, but the details escape me.

There was a 2001 900 and 2002 S4.  The 900 was replaced by the 1000 on 2003.

I'm doing just about the same thing with my 620 and going with the Techlusion TFI Controller. Brad Black has some great words about it and I've done a bunch of other research. It looks like just what you need. You should consider giving Dobeck Engineering a call. I've heard they're very helpful.

+1, talk to Dobeck.  The Techlusion TFI is easily and very satisfyingly tuned with 4 pots, no map required.  If the connectors fit your FI injector connectors, I think it will work fine.  There is only one model for all Ducatis made since 1999, (http://www.techlusion.com/motorcycle/efimotorcycles.asp?make=ducati (http://www.techlusion.com/motorcycle/efimotorcycles.asp?make=ducati)) so you should have no problem.  A conversation with Dobeck should resolve things for you.

the power card is a techlusion that's more confusing to use until you get the hang of the buttons in stead of pots.  but it has capacity to be way more confusing to use on top of that.

all 750ss and 900ss have the 1.5m ecu.  2000 - 2001 900m have the 15m ecu.  2002 900m and 750m use the 5.9m ecu, and 2002 is the year they all went to the st series style frame introduced with the s4 in 2001.

there is only one techlusion for ducati as stated, powercard would be the same altho the powercard has the ability to be programmed at supplier level with fuelling mods that the end user can't see or adjust.  that's the confusing part.

any power commander to suit a 5.9m ecu monster - 620, 800, 1000 - will work just fine.

what's so hard about an st framed monster airbox?

an 800 motor will go straight in too.  nearly as good as a 900, but a straight fit.  reflash ecu, good to go.  much better than a 750.

thank you thank you guys so much. just the info i needed.  [bow_down]

thanks to the thoughts on techlusion and brad thanks sso much for the ECU breakdown

Id love to swap motors in, and im not ruling it out. If a 800 motor is a direct swap then i should have no problems getting a techlusion and no dollars lost on the motor swap in the coming years  [beer]

Fergus - i believe the power commander and also card make a model for the 620 so if you want to make things
easier you could go for the power card since it will come with a preset map for your bike (desmo times allows you to note which kind of exhaust and intake setup you have and adjusts the preset accordingly)

I will give dobek a call, although id rather not buy from them as they charge 250, they can be found for 200, and kneedraggers sells them for 160! but they are backordered

What's that revtech product on KneeDraggers? It looks very similar to the TFI, there's a version for the S4, and it's also made by Dobeck.

Dobeck's product strategy is very confusing...

Brad -

Will the techlusion/dobeck gizmo work with a Siemens controlled Ducati?  Or a Ducati with an O2 sensor?
