Right folks, after my not so big SVA fail, i need to get the lambda setting down on my power commander
fast idle at 2500rpm
co- 0.00 pass
hc - 22 pass
lambda - 1.209 fail
so do i need ti richen or lean out the power map?.
Im not well up on things like this.
All info welcome
Joe
lean out the power map if you can joe also paul at spire sports is very good at sorting this type of problem give him a call he is a good chap easy
to talk to hope this mite help you mate

Hi Paul, hows the imp doing.
Any idea on how much, ie lots or just a smidgen
Think you are running a bit lean
joe are you running standard air box ? have you got a wide band kit fitted? as this would help you sort it out

When you get a map that works could i get a copy?
joe im ringing paul for you i will let you know the outcome
Lambda1 is 14.7:1 fuel/air ratio. Higher than 1 is weak lower than 1 is rich.
You need to richen it up. Just the 0/2% throttle bits of the map at 2250-3250 (+/-250 of the required test revs). The cat will control the CO, though
the HC might rise a bit.
Make sure you've not air leaks on the exhaust. That would also give high Lambda. Seal with clear silicone.

joe paul says you need to get lamda down to 0.209 and also said its a bit of a juggleing job if you make it richer it mite bring it down but the co mite go up so its a bit of playing about mate but if you have a wide band kit it would help you sort it out

Lambda for the test has to be between 0.97 and 1.03!

joe there must be some 1 on here that mite have a map to suit your needs and would be willing to send it you ?
"wont the silicone met/burn, if ive got some leaks. "
Nope!! But clear is better as the black dye is effected by the heat (but still genarally ok).
adrian
will check for leaks then get it tested me thinks, thanks.
Any more ideas, comments are more than welcome
Joe
I might have one that was on my car from SVA, if I can find it I'll let you know. You're welcome to have a copy. 2003 R1 std airbox.

That map look familiar
You arent that far out. With your lap top connected and with fast idle is the TPS at close to 2%?
If so reduce the negative adjustment value at 2000/2500 eg to -10 or -11. This will reduce the leaning out.
Cheers
Jim
