Leaning out the AFR and pulling out a crap load of timing is really the only thing we can do to reduce the HC rate, but it is not a guarntee the car will pass. We were told the cam's are emissions friendly but every state/province has different emissions standards.

Very interested in this topic as I'm considering the same cams.
While I agree it might pass by taking out timing / fuel, once it's returned to "the tune" your still prime time for an on road ticket.
Steve, what are you running for a thermostat / what cats / long or short tubes?
Paul, if it'll pass with a "detune" can it be left in a multi tune chip so as to mess with the on road enforcement folks. Very coool to mess with em at the flick of a switch. :tup

Hey Rick, if the car will pass with a specific "e test" program you can leave it on the multi program chip and turn to that program on the fly without even shutting off the car.

I wish I had an etest machine on my dyno so I could spend a day messing around with parameters trying to get it very close...but then again, close is not good enough

I'm here for Steve to use to try and find a solution, but as I mentioned before some places have different standards and might have been capable to pass in MI but not here...our emissions laws SUCK

Stock t-stat....180 I believe. Almost new Carsound cats and stock manifolds.

I would be going back to Paul to have him fix it but they're just too far away for me to make it over there. :cry2:

Is it when you have a 18 month old with you :LOL:

Move to Toronto....better yet....Ajax would be best. :)

my advise is to take a conditional

(I've done this on the Morgan...as long as your e-test shop haven't got their heads up their asses...they'll write you a conditional considering the cams)

then you'll have some leadtime to work with Meister on a switch-chip

plan???

isn't minimal conditional pass $450+ now with the new rules? .... ouch

Might almost be better off getting a rental car for a couple days for that price, while the car is at Steeda, to let Paul find a tune for it.
Those cams sound awesome, hopefully all you lads that have them can get this figured out, be a waste to have to get rid of them because of poor emmsions

that's not how it works IIRC

if the diagnosis to fix the car exceeds the $450....they don't make you pay the $450

both times when I got a conditional on the Morgan...I simply challenged the shop that the car was never designed or built to pass emissions...and in order to do so, the work needed on the motor would likely cost thousands...it wasn't hard to convince them

all Steve has to do is blame it on the cam swap....and a cam swap is nowhere near $450

I think the amount was raised to $450...to simply keep up with the price increases on parts and repair....for the general stuff that would likely cause a "regular" car to fail.

Tell them its a 5.4 and get it tested as a hot rod. Either that or do like everyone else, get a hot e-test.
