50bux??? wow. am guessing an ST220 UIM isnt exactly a HOT commodity out there. lol. i'd like to get one too, but thats just more power i wont be able to use.

Yes, I understand what you're saying, but I'm not familiar with CDW so I don't know the most likely reason for their lack of a knock sensor... though there are many... very few of which, if any, would be applicable to your average Joe's DD.
It's just a safeguard and if you are confident that you're in tune enough with your car to not need one, that's good... it's just that most people aren't. I like them because they will detect deto/preignition long before my trained ear would, and could possibly save my engine in the event of a problem, or even sudden, dramatic weather change that the PCM hasn't had time to properly adjust for.
I'm just providing the info he was looking for. To be honest, I couldn't care less about what he does with the answer to his question. In fact, the way I see it, I might learn something from his experimentation.
I know, I know... you've hit me with the Pudmunkie wrath before on my build. Thanks for going easy on me this time.
Though you'll probably want to choke me once I get around to swapping in SVT cams while keeping my modded 3L IM's.

I have no intention to leave it with a resistor in the IAT, it's just a bandaid untill I have a 100 bucks to give joey for a tune.
but this is my DD, and I'm broke and I'm going to have to drive it untuned for a while, and the resistor method will help with fuel economy and save my cats.
now I have to look up the duty cycles for the se pcm at various temps, and the optimal duty cycle for the 3.0 with 24lbs at 40 degrees (the average temp outside here now)

Why not just match your PCM, injectors & MAF? It'll run like stock and you won't have to hack anything.

Don't drag me into this, lol. If a knock sensor is available in a given circumstance, by all means, USE IT. Knock/Detonation can cause significant damage long before you can actually hear it, and sometimes, it all happens so fast that you just can't react quickly enough to avoid catastrophic damage (Ask Buckshot about that one . . .) My wideband is a totally different issue. It was put in place, but the wiring wasn't hooked up by accident, and the sensor was fouled. Then I had some other issues to chase, and we all know how I often quit working on my Contour for long periods of time . . . well, I just haven't replaced the sensor yet. But, I have always run an overly conservative tune, with the knock sensor in place, and still monitored the narrow band O2 and knock sensor to avoid any potential engine damage when running the car. I think its a well known fact that my car has never been fully sorted out since I put the 3L in, but I have kept the tuning as far ont he safe side as I can until I do finally get everything right and I can start working on max power output.

It isn't that bad of a combo actually :shrug: I see no reason for any choking going on in here....wait did i stumble across something i shouldn't have :laugh:

two reasons, first being I've only got the 17lb split port injectors and the 24lb oval ones to choose from. it's retarded to stuff narrow spray injectors in an oval port.
secondly, I have an Xcal and only need to get up 100 bucks to have joey send me a tune.
the resistored iat is a ghetto rigged band-aid for when I first get it up and going.

That's cool... I just think it's much more retarded to mismatch injectors. Plus I still don't think the spray pattern is as anywhere near as big of a concern as some make it out to be. But you are the one doing the work so have at it.
Do you plan to alter the MAFS transfer function? I'm sure you realize that you're going to need to do more than just resisitor the IAT.
You might at least have a better starting point if you use the 3L MAFS with the 24lb injectors... in case you hadn't thought of that.
Let me know how it goes - even if it's via PM's to avoid the sh*t that you're likely to get for even thinking about doing this.

hell, your from kennesaw, I lived in douglasville for like 11 years or something. hadn't noticed that.
are you trying to say that because I have 24lb injectors in there that I'm going to need to use a 3.0 MAF even after an NPG tune with my Xcal?

No - Joey should be able to tune for any size injector with any MAFS and any PCM... I was talking about BEFORE you get your tune.

is there any benefit to the 3l maf?

yes in mustang land if you want to change injector size all you have to do is get your mass air recalibrated for that size injector and or get a new mas air that is calibrated for that size injector. very common to do no tuning to the computer. and seeing as the sable/taurus mas air is already calibrated for that size injector it would seem that as long as you can use that mass air snesore with your computer you could avoid the tunning dilema while using the bigger injectors........ no tuning necessary..... what is wrong with that?

No worries, I'm actually impressed with your determination. Too many bums on CEG so I'm glad to see you pressing on. Just know; you'll always be slower than full 05+ swap :laugh:
For others that may not know it: Rara is an worry-wart. Tune it right the first time and you shouldn't have to worry about it.

Just tune the stock MAF or SVT MAF. My stock CSVT MAF is tuned for my 42lb injectors. I bought a 90mm Cobra MAF but decided to not use it and just had my Contour SVT MAF tuned for the 42lb injectors when I bought my XCal2. The car idles awesome and runs great.

THAT sir, shall be proven incorrect.
Wait, that might depend on what you mean by "slower". Are you talking less peak hp/tq, or overall hp/tq, or 1/4 ET? I need something to shoot for here. I may not match Demon's low-13 ET, or David's 230+ HP, but I'm going to be up there before it's all said & done. I will be a legend among Contour owners! :laugh:KAOS_3.0

ok, so which MAF is smoother and larger inside? I'm sure a taurus MAF could be spliced in, even if the connector didn't fit. I have a taurus harness here.
I bet one could be had from pull apart for almost nothing. will one from a 98 work?
