Been back to the local garage today to fiddle with the emmissions.
I cannot get Lambda and CO levels within limits. It is either one or the other.
Maybe a quirk of an EFI big twin but I have tried everything.
Anyone recommend a specialist in this area please.
Alternatively a fully complete SVA ready (apart from emmissions) very very fast mid engine roadster will be for sale at Newark. That would break my
heart but a personal crisis means I have to worry about other things at the moment.
I appeal to those in the buisiness on this forum for help/advice...

Someone here recently passed using a rented Lambda kit. I think it came from Mac#1 for not too much money.
Hope that helps!
Good Luck- don't sell the car!
Atb,
James
Thanks James but I have a rent-a-cat and lambda system from ST. At SVA my CO was 0.0% and HC 55ppm but Lambda 1.1
I can get Lambda within limits but CO goes up.
Getting very dissilusioned since our cars will never have to pass an emmissions test again. Just what is the point....
John
Dont give up on it... if you have other problems, park it in the garage till you feel different.
Try a different garage who knows what their doing maybe ?
u2u jasper re this emisions problem.
He had the same thing and it was a case of running too lean,once he richened it up all was well at SVA.
John
Give the guys at MAC1 a ring, even though your emissions kit is not from them they might be able to help. ( Its worth a call).
Also I know its been said before but make sure that your exhaust system has no leaks, as even a pin hole can let enough air in, to throw the lambda
reading off.
Just use silicone sealant, it smokes a bit untill its fully cured but does the buisiness.

Is it a fireblade engine? (I can't really tell from the picture)
Just wondered if there's anything special about them that's worth knowing re: emmissions.
Atb,
James
Naah, dat be a V twin o' some description, Honda or Suzuki at a guess?
'Tis a Honda SP1, EFI VTR 1000 engine.
Exhaust is completely sealed. Had the emmissions really close but just can't get Lambda and CO within limits at same time. seems that the ECU
fights back when you weaken it off on the power commander.
Tried Snoopys 'fish tank' bleeds but again struggle to get it weak enough and the ECU fights back.
What does anyone know about these companies that take your car and do the final preparation for SVA for you.
The way things are I'd rather throw money at someone else to sort it out for me.

Can only really repeat what others have said - I had murders with this, mine only finally came down when I siliconed up the exhaust gaskets, and wound
out the mixture screws. The CO2 stayed on zero, and the lamda finally came down. I would also recommend taking it to Mark at Mac #1, he does know his
stuff - I can't think of anybody else who would know more about this.
Don't give up, I was already to sell mine I was so frustrated - but now I'm loving driving it.
John,
OK, sounds like you have gone beyond any assistance I can offer you. My recommendation to sort this is to either:
1) commision someone like The Kit Car Workshop (www.thekitcarworkshop.co.uk) to sort the emissions out and give you back an SVA approved car, or
2) Book the car in with Dave Walker at Emerald workshops. Dave is the former technical editor of CCC and knows just about everything there is to on
these matters. I spoke to him the other day about something else and he was saying he is getting quite a few BEC's there for mapping to get
through SVA. He hasn't failed to get one through yet
I am confident that if it's possible then Dave is your man. Call him on 01953 889110.
Hope this helps.

Jasper, Chris, Thankyou.
Thats what I needed to hear. I knew there was somene out there that specialised in this area. I really can't spend any more time on it.
I'll speak to the guys you mentioned.
Thanks again.
John
What is the relevance of the Lambda?, as i understand it it is a reading of fuel air ratio and is used to tell the ecu to adjust it.Is the reading
taken using the cars own lambda sensor?.
Would it be possible to adjust the output of the lambda to read what is required maybe using a resistor?

Paul,
Unfortunately the sensor is external (pushed up the exhaust by SVA man!) . Most bike's don't use a lambda sensor as that isn't a
requirement of a bike test. However, once you fit a bike engine to a car it needs to comply with car lambda regs (assuming post 1995)
A couple of bike engines do have lambda sensors, which are typically the ones offered by Westfield et al. such as the Blackbird (Megabird). That way
they guarantee a pass at SVA as lambda is managed by the stock ECU. Of course a Blackbird engine with dry sump kit is expensive.....
Regards
Chris
That is how i understood it, but thought that with the temporary cat kits there was a lambda and air injection jets.
Maybe this is something to look into further.I am glad i have not fitted my bike engine to my car yet as i chose to fit a crossflow for SVA.

how come silicone sealant doesn't melt? i would have thought it would.
Col - don't ask me, I'm totally mistified, it's still externally visible on mine, 500 miles later!!! I thought it would last 5 mins....
Jasper,
I tried it last night,i have got a bit of an awkward manifold to downpipe joint that is really hard to crank up tight. i have stuffed it with putty
many a time and over time it just works loose. so until i can think of a suitable deisgn to make it easier to do "properly" i thught i would
try your silicone method.
drove it to work today Its amazing how the performance of your car can tail off without you noticing, it was back to normal thanks to a couple of
blobs of sealant, its worked a treat. - reccommended for those temporary - medium length repairs 
its a good descovery Jasper.
They use silicon in a the local exhaust center.
Does seam to work ok, but my exhaust runs so hot the sealant starts to bubble.
Gonna drive back to SVA center tomorrow and have another go. Reckon if I keep turning up they will take pity or get fed up with me and give me the
ticket....
John
Just start your engine up a few times untill it stops smoking then it works fine. Ive got some on my headers and its even OK after theyve been glowing
red.
good luck spunky. you'll get there.
John,
I really hope you get through. All the best for your retest
