748/999 Build

Extended the 999 injector wiring loom to reach the 998 throttle body plug (plug on 998 TB is opposite to 999). Also enlarged one of the 25mm holes to properly accommodate the multi pin loom connection. Should be the last time the airbox has to come off.

 

Have you checked the TPS works the correct way .. ie 0-100 not 100 -0
I can’t remember 998 to 999 but I know the 999 is the opposite way to the 1198

 

Ah... I didn't check or swap the two wires. I literally just extended the cables. If you've anymore info on which ones to swap, that would be great

 

there you go tps for a 999 ABC on the loom is


just need to find the tps abc for the 998tbs

 

Legend! Thanks that’s amazing

 

As FE says if you do need to change it, and its only about the direction of rotation of the switch, ( you could probably see just by looking at which way the butterfly rotates comparing the two TBs, you only need to swap two of the wires...

 

Fantastic. I'll check the 999 TB's rotation. Hopefully it'll be quite a simple fix

 

Thanks again for the help Chaps.

So I finally got round to checking the 999 tb's rotation against the 998 set.

The 998 set. Both butterflys rotate to the left.

The 999 set. Top butterfly rotates to the right, bottom butterfly rotates the the left.

I'll have to take a closer look at the diagrams above to see it I can work out the correct wiring sequence etc.

 

Look at it as rotation cw or ccw

 

So in these 998 tbs knowing the cable sits at the front off side the TPS will rotate clockwise 0-100

 

Whereas on a 1198 tbs it sits the other side so rotates anti clockwise 0-100

 

Ah ok. Get it now thanks

 

Not much to report of late. Been busy working from home and home schooling the kids, so not had too much time on the bike. I have however finished the hand controls. New Brembo lever for the MC and a new standard clutch lever have been fitted, along with a new Domino QA throttle and billet clipons.
I have finally deceied what I'll be doing with the ECU and loom etc. I have been speaking to someone who can unlock a 999 ECU, so I'll be able to run any 999 dash along with any ECU and key. I think this will be the best and easiest option for the 999 motor, eliminating dyno time etc, so it'll essentially be plug and play.

Got the bike out in the open a week or so back really happy with the progress so far.

 

Good work, Russ. Got the front brake lines ready for you.

 

Have you? Mega, thanks mate.

 

Looking great.

 

Battery box is on the left to use the 999 loom
You can cut down a 999 or 1098 battery box and mount it on the near side you can get a carbon 999 rs one and use that
Then mount the ecu above the battery box and the solenoid below then move the regulator to the right side

 

Oh and you would still benefit from dyno time regardless

 

100% but it'll get me 90% there
