I had mine set similar to yours at 2500-3000 which was ok but then changed suddenly. Wondering if I have an issue somewhere else. The idle was set at
-12 ish but was still rich. Having another tinker today.

set you idle to 14 or 1500 via the screw as it makes it just a little better... the limit is 1000-1500...

Do you hav a link to the eBay item? I got mine off eBay. I had to weld it together. I'm not sure if its working properly. Was thinking of trying
another type

Hi
We had the same problem on our R1 engine, it was the Air induction system
causing the problem.
Took the air intake pipe to the AIS away from the airbox & fitted a stop valve
during the test gradually turned it down until it was off, Lambda was then fine.
 
AIS Shut off valve
Good luck
Looking at your archive picts, nice car but do you have a rear view mirror ? .

Hi doobrychat
Have you got your emissions sorted now? Im still playing, i seem to have had the same issues as many others on here. I got the fast idle sorted but
lammbda was high on tick over. Got a few more things to check out. Ive just fitted an auot tune system to read lambda. Its switched off so not
correcting the map for me.

hi there
well i first had as yoshi box then i had suzuki SDS system but still to no avail... then took the powercommander 3usb off my 1000 k6 motorcycle and
mapped it with my laptop on a gas analyzer...
through iva now so i'll decat it and block off the clean air system and sort out a proper mapp for it

That must be a good feelin to get the iva sorted. Did you have the air system connected to get the emissions sorted? I've blocked mine.
I'm close to getting them right just making sure there are no leaks anywhere that will upset the lambda ect

hi had the air system on...
i took the advise of another post in this category and got a bit excited with some exhaust paste to ensure no other air leeks getting into the
system...
it looked a bit rough for my liking but its all cleaned off now...

I'm not sure when the air solenoid actually opens. At the positions for the test I think the valve would be closed. I think it only works on
overrun? Ya my exhaust is leaking at the collector box pipe work connection. Guna put some clamps round to try and seal. It's knocking the
lambda way out

the clean air valve is fully open at tick over then closes as the revs go higher on the k1 k2 model..

Hmm that's interesting, you had your idle at +6 on the pc. I wonder if running richer actually made it burn better? Did you manage to take the
co reading before the cat? Just wondering how good your cat was working. I got the same cat as yours, it seems to be working good but needs to get
pretty hot before it works. If I rich mine up any at all the co reads 3 % or so at the tail pipe

Sorry i can't remember what it was with a cold cat..
it did make a lot of difference with the cat hot and does take quite a while to get hot, it does depend on how far down the pipe it is.. I put mine as
close to the headers as possible..

Ya my cat is next to the collector box. Can't move it any closer. Once I've got it air tight I'm hoping to have a stable reading.
I'm am using one of those cheap gunson co readers at home. It's just to get an indication that its going in the right direction.

How do
Ive been in the local garage again today. Still not achieving the correct emissions. For both idle and fast idle, the lambda and hc was spot on. The
co came in and read very low tgen suddenly went up to 2% or so. I set it up manually then let the auto tune do the work. Even when i set the target
afr to 14.7, lambda went high but co and hc was spot on. Im not sure what more i can do realy, its doing my head in
Not sure if i have an issue with the engine or if its purely set up?

first thing is make sure the exhaust is 100% air tight.. to test mine i back filled it with air and some soapy water was sprayed all over it
externally.. lots of places i thought wouldn't produce air, but did!! sealed them up and AFR went to a much closer figure then before..
then found the power commander was the only way to go..
cat was red hot and spent many hours tweeking with other software before the power commander went on.. i did spend £15 on fuel to map it as thats how
long it was running..

I've got the exhaust pretty good. But I will check it again. Was your engine running steady? Mine hunts a lot so the emissions move around a
lot. The lambda wasn't that bad, it was the sudden changes in co with a steady lambda reading? I would have thought an increase in co would
upset the lambda

mine doesn't hunt at all... are you running a k2 1000 engine?
have you had your throttle bodies balanced?

K6 mine and ya balanced up ok. The difference I can see at the moment it the pair valve. I've blocked mine. Not sure if I should start again and
reconnect it? A few people have said to block it.
