Whats the limits for Lambda? 0.97 - 1.03 IIRC? I think thats what it said on my test print out, and I got a result of 1 as well.

Never seen exactly 1

Even new vauxhalls that come in for their first MOT fluctuate from .99 - 1.01

My cupra made 1.013, abit on the lean side like most un-altered EFIs engines. When i install my N2O kit, i shall put it on the emissions tester so i can get my nozzle sizes matched

Are you using a SUN emissions machine?

If so thats why, Because the SUN machines are a bit more sensitive than Crypton. The 1.013 result above would have been 1.01 on a crypton Gas Tester!!!

you will need a wideband lambda to do that plus you will have to have the engine under load for it to work
