Me neither but I'll bet his penis is a lot bigger than the kid with the M4 ;)

You and the guy who thinks Dubya is a war criminal are about the only ones who come across as having an ounce of brains and since thoughts on Dubya amount to opinions they don't really count. Much of the remaining comments would be laughable if they weren't so indicative of gross ignorance.

The gadget at the airport that looks like a booth and puffs air is an explosives detector. As both an engineer and pilot type rated in the B737, B757, B767, and a host of other turbine powered aircraft from business jets to former Soviet Bloc fighters like the L39 in my avatar, and one who has...

Because not everyone uses a dyno for tuning. Some tune on their own and use the dyno for verification. After all a dyno's capabilities go well beyond tuning. WBs are for the home tuner who can't afford NDIR equipment and also want a method of monitoring. I agree with Ian though, you'd better be...

Ian, are dyno shops really using WBs to tune these days? Huh. All the ones I'm familar with use NDIR. I'd be very nervous tuning off a WB but once tuned I don't see too much of a use for it. If I was going to use it I'd also add EGT.

Good posts by Red Dragon and jimi....you're a patient man ;). PorterzSupra: The ecu uses the stock O2 sensor to adjust mixture during crusing and hot idle. I don't see what's so confusing about this as it's all been explained in previous posts. The basics of this stuff can be found all over the...

If I'm not mistaken I told you either in another post or a PM. It's also in your service manual but what the heck, here goes: Warm the car up. Short the diag connector. Connect your meter to Vf and ground. Hold 2500 rpm and look for the meter to fluctuate. A minimum of 8 flucuations in 10...

I seem to be constantly repeating myself on these idle and TPS issues over several posts. Did you do as I suggest? Did you check the TPS with a meter or short the pins on the harness and see if the code disappears? Your lack of injection is a separate issue. Weren't you the guy who was having Dr...

Did you ever check the O2 sensor counting using Vf? It'd be nice to know if the loop is out of range or still in control. Driving it rich isn't going to hurt anything other than your cat and only then if it's real rich. Not to worry, wait until you get everything installed and tune from there...

Joel, I'm no a whiz on modding so I'll leave it to the guys here who know but no matter what you do, the fact that you're willing to do your homework and learn puts nothing beyond your reach. It's what separates the pros from those with endless frustration. There is a lot of talent here if...

Thanks....I wish I wasn't so verbose but it's a curse ;)

Not only are you sharper than the average old fart of 22 but you've got this PCV thing down pretty good. A few things for those still pondering: *edit*..Other than to say shaeff is a sharp guy, based on NashMan's post below I think I'll just go ahead and delete everything I wrote ;)

What Nick said. A lot of people seem to forget the TCCS will still run with bad sensors. It may not run well but it will run. This is designed into it so that a failed sensor won't strand you. I'm only talking about feedback sensors like coolant temp, AFM, O2, IDL contacts, ect.. Something...

Lol yeah, I get the distinct impression you don't have nearly the problems with your car others do. That intake setup of yours also proves you're a stickler for detail ;). mkiii: EGT is Exhaust Gas Temperature. It's usually measured with a type K thermocouple. There is a direct corelation...

Yeah, "tune" is a misnomer. Search around, there are plenty of WB's to choose from. I thought there was a sticky or review section here? They all do the same as far as A/F but you may want choices like data logging, PC interfaces, things like that. Even if you connected the WB to your ecu it...

Lol, baby steps indeed is the only way to go. Again, an O2 sensor only measures O2 so one has to be careful. The bottom line is you have to have the right gear, know how to use it, and approach with caution ;)

jimi: Yeah, that's the problem. NDIR analyzers aren't cheap and take a few seconds to react. I know, I own two. But they work great as long as you start out rich. EGT also works as long as you start out rich and the probe is in the right place. Fwiw EGT is what we use in aviation and we run...

The stock sensor is there for one reason: to keep the mixture at stoich during steady state conditions because the cat needs stoich to work. As I've said before, stock O2 sensors exist solely to serve the cat converter. The stock sensor is part of the engine's feedback loop. It makes it run at...

Ugh....I implied a WB's signal can only measure stoich. Bad writing there ;) Mkiii: You got it. A normal A/F meter isn't any good for tuning but it's far from a total loss. It tells you at a glance the O2 sensor is cross counting and the entire lambda trim loop is working. It proves the ecu is...

Again jimi, well said. The entire point is to tune for a best power mixture at WOT. As a point of interest the ecu uses the stock sensor only during steady state conditions. It's ignored during cold idle, WOT, and during accel and decel. In fact you'd be surprised at how often the O2 sensor on...
