Big day tomorrow: the Blackfly's first e-test since cam swap & taller transmission

[MetroMPG]

Its emissions test appointment is tomorrow afternoon.

EDIT: the procedure & pollutants being tested for the Ontario Drive Clean test can be found in this file: http://www.ene.gov.on.ca/stdprodcons...rod_080001.pdf

I'm seriously hoping the car's emissions haven't somehow been made worse by the cam change and taller gearing.

There is bound to be *some* difference from the previous test (we do it every 2 years in Ontario) due to the gearing, simply because the engine is going to be running at a different RPM on the dynomometer.

Fingers crossed...

Do they give you numbers or is it just a pass fail and do you have the numbers for the last one? Good luck

[MetroMPG]

I get a printout with numbers. And I have the numbers from last time, so we'll be able to compare.

[TomO]

You should be fine and well within specs as far as emissions go. Don't sweat it.

[MetroMPG]

Well, I didn't get my test today. The garage called me this morning because their dyno was down, so I have to call them back next week and reschedule.

Nice to read your thoughts on it though.

[MetroMPG]

Passed the emissions test today. Happily, TomO was right on the money.

I'll post a comparison of today's test and the one from 2 years ago when I dig up the previous figures.

[MetroMPG]

OK - here's the comparison.

ASM 2525/CURB IDLE TAILPIPE EMISSIONS INSPECTION

June 9/09, odometer at 24,619 km.

Emission ... Limit / Reading @40km/h ... Limit / READING @ idle

HC ppm ........ 66 / 10 ...................150 / 10
CO % ........ 0.37 / 0.0 ................. 0.7 / 0.0
NO ppm ....... 505 / 1 .................... na / na
RPM ............ 2621 ....................... 823

Dilution ... 14.60 / 14.70 (don't know what this is) EDIT: for definition, see post #18.

-----------------------------------------------------------------------

Dec. 12/07, odometer at 14,481 km.

Emission ... Limit / Reading @40km/h ... Limit / READING @ idle

HC ppm ........ 66 / 21 ...................150 / 6
CO % ........ 0.37 / 0.01 ................ 0.7 / 0.04
NO ppm ....... 505 / 1 .................... na / na
RPM ............ 1709 ....................... 898

Dilution ... 14.51 / 14.04 (don't know what this is)

-----------------------------------------------------------------------

Aug 24/05, odometer at 2,460 km.

Emission ... Limit / Reading @40km/h ... Limit / READING @ idle

HC ppm ........ 66 / 9 ....................150 / 8
CO % ........ 0.37 / 0.00 ................ 0.7 / 0.00
NO ppm ....... 505 / 53 ................... na / na
RPM ............ 1685 ....................... 634

Dilution ... 14.20 / 14.40 (don't know what this is)

-----------------------------------------------------------------------

So what does it say? Some emissions are up, some are down. The worst 2007 increase (HC ppm @ 40 km/h) is now @ 32% of its max. allowable.

[TomO]

I'm curious as to the rather large jump in idling RPMs. Any mods that affect the idle speed?

And congrats on passing well within limits!

[MetroMPG]

Yeah - thanks. I'm happy I can keep my XFi cam.

As for the idling, that just seems to be the way the car is. It's never had a really predictable idle speed.

It was the same with the previous Firefly. (Hey... you just made me think: I should see if I can dig up the e-test from the first car.)

[MetroMPG]

No luck: unfortunately, I gave away my first Firefly's e-test papers to the new owner.
