Went to do etest, with magnaflow 3 inch in out with split air tube.



failed twice



here are results of first test:



39 km/h roll on dyno

HC ppm limit =73, My car = 191

CO% limit = 0.41, My car = 0.06

NO ppm limit = 836, My car = 39



2nd test. Apexi BOV adjusted so it doesn't flutter (losened preload, maybe i should increase preload?)

safc -10% @ 1000 rpm

safc -17% @ 2000 rpm, operator manged to get the car to buck on the dyno

everything else -10%



results are:

HC ppm limit =73, My car = 145

CO% limit = 0.41, My car = 0.01

NO ppm limit = 836, My car = 126



So NOX went up, HC ppm went down, but not enough. i need more.





Mind you i passed the idle test, my HC ppm was 75 at 750 rpm.



HELP!



Things i should start doing?

 

Air to cat is hooked up?



Car was good and warmed up, cat was hot?

 

Yes and yes

 

picked up a set of plugs, going to install those and see what happens... this is getting expensive... first etest was 35, 2nd was 17.50

the 3rd will be 17.50



after that they are 35 bucks again

 

Commercial Alcohols





They might be able to hook you up with a little sumthin' sumthin' that'll make you pass.





@ Airport Road and Hwy 7 in Brampton.

 

Alcohol worked for me!



But I wouldn't really recommend it on a nice rotary engine. Especially turbocharged..

 

does it decrease the HC?



i'm thinking of riggin' the air pump to bypass the air control valvae and dump as much as the cat can take.

 

what alchol and ratios did u run to get it to pass?

 

I poured a bottle of alcohol(like those 14oz bottles from walmart),to a quarter of a tank and I passed.But dont have more than a quater tank of gas.

 

5 parts gas to one part methyl hydrate, I think after that ratio the HC went up but C02 down.. I almost failed from the HC. I believe. I can't remember clearly..
