exact parts needed for top end swap into olds

[IsaacHayes]

The TB will bolt up? Are you sure? I thought the plenum was different as well? He said he couldn't bolt up a 3400 plenum before to his TB....

This combo is weird and rare and only in the A-bodies. I don't think anyone has modified one before, at least to my knowledge. Good news is you can tune it with tunercat software. Burn chips or get an ostrich emulator. It's different from most 3100's/3400's in the TB/MAF are built in and it has no MAP at all. All other 3100's from 94-95 have MAP but no MAF. Then in 96 they went to OBDII and got a MAF but kept the MAP....

[3100 MPFI]

Now that I look at it closer, it looks more like he has a 4 bolt throttle body instead of a 2 bolt.

Let me do some reseasrch, and see what I can find out.

[3100 MPFI]

This is a 1994-1996 Ciera 3100 throttle body;


I would have to just try it myself to see what is different about it.

If you can get under your dash can you take a picture of the top of your gas pedal? The part where the cable is attached to the top of the pedal.

In 1997, the CIERA was changed from an A BODY to a W BODY, so if the top of the pedal is the same, you can probably get a W-body throttle cable and use a normal throttle body, and a normal MAF instead of the integrated one.

If I can get to the local junkyard (they will not open again until after new years), then I will check on the throttle cables myself. That is, if they still have an A body there.

Another thing that might help is if you pull off the throttle body, and take a pic of the intake manifold flange.

[IsaacHayes]

Yep, gonna have to go with 3400 56mm TB, throttle linkage bracket and new throttle cables. No way around it. Also you'll need a separate MAF of course.

The next question I guess would be is the Ciera MAF the same technology (digital) as the 96+ 3x00 MAF's?? It's a Hitachi I know that much. I doubt it's analog like the old ones so you're probably safe.

[3100 MPFI]

Check to see how many wires your MAF has. If it has 3, then you can probably use the newer one. If it has 5 then you can probably use the older one.

This is one of those cases where the more pics you can get us, the more help we can give. Find out how many wires your MAF connector has, what colour they are, and in what locations.

[IsaacHayes]

From looking at his pictures: 3 wires.
A= yellow
B = black
C = pink-ish (maybe red with white stripe)

[3100 MPFI]

That wiring is the same as the 1996 Grand Prix 3100 MAF, so it is most likely he will be able to use it with no problems.

[IsaacHayes]

Good deal. Now go grab those extra parts needed!!! (TB, linkage bracket, cruise/throttle cables, MAF)!!!

[gboogie99]

why couldnt this be a lil simpler

[IsaacHayes]

Hehe, cause you have an oddball 3100!!!! BUT look on the bright side you can tune it with available tools and end up making more power than us that that can't!!!!

[gboogie99]

yeah its an oddball...
what is gonna be my best bet on tuning? i saw a thread on somenone trying to crack the code for obd 1.5

[gboogie99]

one more question, how do i take apart the throttle cables on a the newer TB? I am going to pick one up at the u pull it yard this weekend...

i am going to pull the old tb and maf off tomorrow after work so I'll have pics of it then!

[3100 MPFI]

not sure how to do yours.

On my Cutlass Supreme, if you undo the cable from the bracket (just use a flat screwdriver to lift the locktab, and pull it out to the side) you can just pull the cable out of the holder, and spin it around and the cable comes out of a slit in the throttle body. There is a small dowel like thing in there that slides out as well. Once you pull the cable around, you will see how it goes.

If I don't have a good pic of it, I will take one for you.

[IsaacHayes]

Undo the cables? I usually open the throttle all the way open, jam a screwdriver in the linkage somewhere so it holds it open, then take another screw driver and push out the lead barrel on the end of the cable while pulling on the cable to give it slack. It usually falls out that way. But 3100MPFI's method seems easier, just take the cable out of the bracket and then you'll have all the slack you need to take it out.

That thread was me. You don't have the un-tuneable ECM though. Your code is already cracked. I'm sure someone could make a TunerProRT definition if they had the info, maybe even from the tunercat one. But TunerCat is your only way right now.

http://tunercat.com/tnr_desc/ecm_sup.html your def is $1FA.
$1FA 16196387 94 - 95 Buick / Olds L82, 3.1L, V6.

I believe it's $70 for the tunercat program, and another $20 for the definition. Not sure if once you have that you can use it with tunerpro or not. And if you want to emulate using ostrich/etc so you are not swapping chips all the time then you'll need the tunercat that does real time stuff. Maybe someone else can tell you more specifics but that's all I know about it. I don't know if tuner cat can data log with that def or what. I know it can edit the ECM with it.

If it can't data log you'll need to find a tunerpro rt .ADS definition to data log. Or make your own. To make your own just look at an existing one that's close to your motor (say a 3.1mpfi, but not a v8 one). Then go to moates.net files and get the ALDL.zip. Then open it up and find your data stream. With that info and the other .ADS as a reference you can make your own. The datastream (I just looked it up) for your car is A263.DS . So open that file in the zip and it has the locations for the data and what formulas you use to convert it to readable data.

I learned all this stuff on my own in a few days.

what is the part number for the metal intake gaskets? i got part no MS98003T for the gasket set. i dont need the whole set just the upper an lower gasket...
