Powercommander - leaning out for MOT
Colnago_Man - 19/5/10 at 12:46 PM

First MOT day tommorow with the R1 engined car. At the moment I have no reason to suspect it will fail on emmisions but if it does will leaning it out via the powercommander lower the emmisions or is it much more complicated that this?

I've not got a laptop hooked up to the power commander so I would just use the three buttons on the top to adjust the fuelling on the lower rpm range?

I think its much more complicated than that, the factory did mine and I then remapped with something a bit meatier.

It took them nearly an hour using the pc, laptop and emissions analyser.

It is more complicated than just leaning out as you need to get HC CO and Lambda all within thresholds.

If you do start playing with the map dont bother about anything over 3000 rpm as MoT will be at fast idle only (c.2500rpm IIRC).

If you play with a the settings do it with a steel probe on a RR rather than the normal rubber one that MoT testers as the rubber ones catch on fire and die. I have killed two so far

Leaned mine off ( well Alan did it for me at the mot test station) with the three buttons for lowering the emmissions for the lower rpm range, it took only seconds to do and it worked.

as above i helped edd with MOT he was lucky as he only had to pass at the old emmisions limits at 3.5%
his zx12r engine was mapped for power and was a fail untill leaned off with the face plate buttons all you do is hold the 3 buttons down then while still holding them turn the ignition on then a press will richen and a hold will weaken you may have to weaken right off then increase the idle HTH

ETA remember to put the fueling back before driving home

Im beating you with 3 kills so far... i even killed one on my SVA test. Luckily the probe still worked, and i passed the emission test

Paniced for no reason, sailed through the test.

Only trouble was the rain that was coming down for the drive there and back.
