2003 Daytona 2003 Rough Running Cutting Out Rich

Thanks buddy, MSS performance are dealers for Dynojet, He rang them to see if they could help. The units are Obsolete They did say i maybe able to get one off ebay and then they could map it for £600.

All i want is a bike that runs ok because at the minute its horrible below 6k

Still after a standard ecu if anyone has a breaker on here?

 

Im after another ecu. I believe the Power commanders piggy back if the Original.

I've filled a online form out fingers crossed a breaker will turn up.

 

So i managed to connect the lap top at last.



How does this compare to a 10181 map? sorry for the quality of image

 

Ok Here we go,

So I’ve been busy, finally worked out how to upload maps and reset the TPS. Went for a ride and she seemed a lot better, But!! I decided to check the plugs to see if they were burning any better since uploading the 10181 map , big mistake I broke the fuel tank unions to the feed and return lines doh!

So i managed to Use a Brass 1/4 BSP to 1/4BSP 90 degree union for the return, lucky enough the Feed union wasn't damaged

The plugs after 50 miles of the new map looked like they were getting better, but i decided to go the whole hog whilst waiting for the union to turn up in the post.



I did more work, Removal of the throttle bodies to Clean, along with the Intake manifold, using redex and a Tooth brush!
The Frame and engine got a degrease and polish. Along with rubbing down and painting the Oil cooler lines and radiators.

New throttle cables Fitted as the old ones were clearly slack and and fraying inside the rubber sheath, Turns out this was also causing the butterfly’s to stick in the throttle bodies.

Chain slipper also worn right through and come off in bits so that was replaced Genuine Triumph and along with new JT sprockets and DID gold X ring 106 chain keeping the stock gearing.

I Also drained the coolant and refreshed with Antifreeze along with fitting a new temp sensor which was a bargain at around £10 as this was from a automotive fitting. "Vehicle Parts" is my business Also i changed the Air filter not that this was really dirty but hey i was right there.

The Bike now runs and rides a dream, No surging at 3k or below and packs a proper punch when needed.

I think the previous garage had issues and altered the 10181 map causing the bike to run way to rich sootting up everything.






Also Cleaned up the Rear Suspension assembly whilst i was there and regressed everything.

 

Short lived Huston! we have another problem,

Ok she is NOT running rich any longer but now i have a idle issue which has just come up after covering 80miles since getting her back up and running.

If i go for a ride, come back she idles at around 1,400 then slowy on its own increases to a 1,800rpm idle?

Any ideas??

 

So start engine up, from cold, sprayed Brake cleaner up and around the intake, nothing altered. thought id let the bike come upto running temp untill the fan kicked in.

Ok peeps, after i got her back from work she was idling as the image shows, So had tea and went for a coffee with my wife, came back after the bike had cooled down.

Plugged Tune ecu in, Reset the TPS following the link below obviously not loading any map.



Started the bike she went upto 1,500 and gradually came down going as low as rpm before settling around 1,250rpm raised slightly to 1380 when the fan kicked in but a whole lot lower than before so then i turned her off.

Restarted when she was readin 71 degree's tunecu, Tested the iacv which i heard do its thing. Restarted the bike and she ticked over ranging from 1000-1250rpm.

Shall i try and reset adaptations? she does fluctuate quite abit wondering if the throttle bodies need balancing?

Just took her up the filling station, idle fine if a little low 1,100 gave her a run approx 5 miles quickly got back home still idling fine approx 1,100rpm

I’m wondering what will happen next. I will report back

 

So bike still playing up when i got home from work, High idle so took some reading on TunEcu can anyone tell me if these readings look strange.

Temp ==== idle values

60 degres, -2. 3.99% (68) === Reading "warm engine not running"

60 degres, -2 3.9% (34) ==== After starting lambda 0.950v 0.04 1,960rpm
,
83 degres, -2, 3.9% (28) ==== After running for a little while lambda 0.935v 1,710rpm

Reset TPS

89 degres -2, 3.9% (31)% === After resetting tps the RPM slowly increased to 1,500rpm??
