o2 replacement is different than an emmissions ready ness test.


there is many bs on the web about drive this and that speed. 

some tips i have learned for emmissions readyness pass:

a 10 mile anything drive we reset all with two important things:  gas tank must read 1/2 full or less, must be a cold start.  ie collant cloose to ambient. 

there are 5 or 6 on my zj   i had a cracked canister hose that fixed the last two tests.

Honestly, have not even checked the code yet. Mostly concerned with the miles necessary to get it to be "ready", since it is not currently road legal.

shouldnt take many miles. just speed- i had to go one 390 to get the last one.

P0500 - VSS

Resetting does not work. Will require further diagnosis. Bah!

[M4wdFab]

speed sensor- you have goofyness with your doubler?

[Harrison]

Yes, there is a goofy adapter to go from Bronco to Jeep VSS. Seems to read on the speedo when moving, but bounces around sometimes when driving. All in close proximity to exhaust, need to investigate for shorts. Unplugging, cleaning and plugging connector back in made no change.

Dan's busted D20 output has me thinking. $500 to upgrade rear output from coarse 10 spline to normal 32. Seems I could probably do a 205 and 1330/50 driveshafts for that much.

I'm sure a C6 is worth almost nothing, is that a decent price?

My doubler has a baby intermediate shaft between the 231 and D20. Assuming I'd just need to source the correct shaft to go from 231 to whatever a Ford 205 input is? I read that the Ford case has 6 studs on a slightly larger circle than Jeep stuff and holes can be drill a hair to make it work.

Hey Mike... do you have a Ford 205 on something going to scrap?

[M4wdFab]

i broke alot of dana 20's

once you get them mounted right and dont have your yokes over extended, the cases break last. 

[Harrison]

Coarse 10 spline outputs even? CJ and Bronco D20s are not quite the same internally... Though splines may be the same.

I have a scout D300 if your interested in making it strong!

[mr.mindless]

I have a divorced 203-205 doubler with 1350 everystuff and a new rear CV shaft that would be the beefiest strength upgrade there is for a "cheap" 3 speed setup.

[Harrison]

Ideally I would keep my doubler box and throw the 205 on it.

Maybe I need to give my setup more of a chance. Research shows CJ cases share the same 10 spline as Bronco. Dan was hopping pretty good with 4:1 in front of it and 39" stickies...

[M4wdFab]

ya mine were all coarse spine.  i broke 2-3 rear outputs, a front output, and cracked a case once.

used to bring a spare to big dogs with the CJ after 10 min into a RC trip it snappered.

[Harrison]

DMV person was wrong, imagine that.

Failed emissions yesterday, granted a 60 day extension period from yesterday, stood in line and renewed reg today. Success!!!

Sucks my reg still expires at the same time in December 2015... but at least I get two more summers out of it! They don't revoke your reg if you don't pass emissions in the 60 days, just means you can't renew next time around until you pass and you don't get a free retest.

[mr.mindless]

What's your emissions no-pass issue? Fixable, or not so much? I'd guess evap failures with the fuel cell if nothing else
