ECU swop 07 to 05
 

I have now swopped my 07 ECU with O2 sensor for a 05 ECU with no O2 sensor. I have done this to gain full control of the fuel injection, so I can fully adjust the fuelling with all my mods.

I bought a complete wiring loom for a 05 XTX & fitted it to my 07 XTX with no modification needed to make it fit, then coded the 07 immobilizer & keys to the 04 ECU with no problems.

:dentist:

I have a headache just looking at that lot ...

Plug and play? :smile[2]:Only Kev and a few other can undertake such a task, I couldn't even change a light bulb without breaking something!!

You know me, anything is game on my XT's. If we don't try different things we will never know.

Time to move onto the next mod.:laughing5:

It is difficuklt to tell be the pictures, But where there big differences in the Loom or had they just added bits for the O" sensor etc? :brain:

You keep making us proud every day Kev! :sunny:

Full respect to your efforts and research in this forum!!!:family:

the information Kev sorts for us all is something else.

More Plug and Pray I'd have thought.

Working in IT I've built a few computers so I've had all the parts and cables all over the floor before but that something else entirely!

Respect to Kev, I'd be running out the door screaming with all that lot! :biggob:

Hi Kev
all very nice but does that mean that you have given up on a mod that works for the 07 XTs? Mine is still riding like a bronco when its cold and damp. Was ok in the 'summer'.
Does anybody know what Aprillia and MZ use in their bikes. Same engines with the same output but as smooth as silk!?

The main looms are the same 07/05, except for the ECU part of the main loom it is totally different. The 07 ECU has 34 pins & the 05 ECU has 26 pins with the wiring allocation in the plugs in different locations.

So it is plug & play as long as you change the whole loom.:campfire:

No not given up, I am getting my bike ready for the PC5. I will work on the 07 mod when I go on a months holiday early next year.

Good to hear that, thanks. And for going on a month holiday? How do you guys do that?

Rob

We all get 4 weeks leave a year in Oz & I tend to take mine all at once to have a good break.:bbeer:

Wow, Kev! I always tend to get worried when one actually needs a degree in electronics to tamper with a bike. It's not like my old Guzzis, where precision sledgehammering usually sorts it all out. I'm glad we have Kev here to guide us electronics novices into the jungle of cables, ECUs and remapping schedules... ;-)

This is not a hard mod to do at all & sure anyone could do it.:happy:

The programming of the immobiliser & keys are straight forward as well.

Kev,

Blimey mate. My worst nightmare. Small wiring jobs are OK, but a task like that would send me packing. I hope the outcome is what you expect once you have dyno'd it.

Keep us posted, and keep up the task in hand

Cheers

WB

Without the help Of WB I would not have been able to do this mod. WB organized my ECU from Holland to UK, then posted it off to me in Australia. A great mate to have & getting a brand new ECU for 66 Pounds was a bargain price. Wiring loom came off Ebay UK 30 Pounds.
:signthankspin:

As for the running, my bike has never run so smoothly with all my mods, having total control over the fueling is great, I am in love with my XT again. I loaded one of Freez's fuel maps & have played a little in a few rev ranges to suit my bike. I am off to the dyno very soon for a custom fuel map the only way to set the fuelling. :111:

After playing this weekend & using Freez's 06DNA fuel map my 07 XTX, it has never run so smoothly through out the whole rev range, I am real happy now. Still going to do a custom fuel map soon.
:116:

Forgot to add I recently swapped my 09 XTX ECU & wiring loom for a 05 complete wiring loom & 06 ECU.

Thanks for the advice on this thread (and PMs Kev)
I don't think I'd have braved this one without abit of encouragement.
Got an 05 wiring loom from ebay for �30.
Got a new ECU from Yam dealer for �132.
Had already purchased PCV,

I know you lot like photos, so here you are...

I hope there's no bad karma using donor parts. I did feel abit sorry for the 05 XTX the wiring loom once belonged to. It was abit like a major nervous system transplant.
I thought it would take a couple of hours to do the job. Reality was more like 4 hours. rewiring the alarm slowed me down abit.
Started first time. and like kev said, registering the keys to the ECU took all of 20 secs.
Verdict - Very smooth running at part throttle. lurching seems to have totally gone!
Slightly jerky when opening the throttle from fully closed, hoping this will smooth out with a custom map. Still playing with the Co setting which was set to zero on the new ECU. this might help.
I might postback after a weeks riding.

cheers for the headsup Kev. ;)

well done!:eusa_clap::eusa_clap::eusa_clap::clap::clap: :clap::eusa_clap::eusa_clap::eusa_clap:

Nice work mate you are the only other person that I know of who has done this conversion, I am sure you will be happy with the results once you have a good fuel map with that set up. :eusa_clap:

Now you tell me, haha.

Can I now be forgiven for asking how to connect the PCV a few months ago.

Master electrician.:icon_cheers:

I know its an old tread but, how did you register the keys to the new ECU?
I have the 00 ecu and a friend have the 01 version and his bike does not make big explosions when close the thortle like mine.
I will be interested in make a ECU swap in case that I can change it and then register my own keys, and don't have to buy new keys or switch.

I see you never got an answer to a valid question?
 

Did you manage to sort it out in the end? and if so what exactly did you do?

I think I can partially answer your question "I see you never got an answer to a valid question?".
MZs had 26mm Teikei carburettors on their 660 lumps and I have fitted an Aprilia, (who use a 40mm FI throttle body), Pegaso Factory engine in to my Tenere and the engine internals are exactly the same including the gearing cluster. The only difference were the asthetics of some minor exterior casings (embedded logos) and their final drive gearing is 15 T over 44T.

I attached my original 2009 fuel injection throttle body which is married to the 8591A 00 ECU . My bike had a Kevs fuel mod before and after along with a DNA filter / open snorkle and GPR pipes.

The bike now rides exactly the same as it did before it blew out its 3rd gear with zero changes to performance. There is still a noticeable 'switch / surging' between the open and closed FA loops, but only sometimes and also occasionally on gear change downs . I'm also using Kevs O2 eliminator, both before and after.

In conclusion. .my guess is the early Yamaha ECU mapping has the quality of an 80s Amstrad as the MZ / Aprilia engines are exactly the same as the 'Yamaha' just that they use different fueling systems but are known to ride better..
