+REP man this is some great stuff to know!

Are we sure there were no half-years for this CTM? I'm still shocked they did their math correctly (or took a loss) during the OBDII upgrade on January 1st 1996...

To summarize:
1995- OBD1
1996- OBD2
1997- OBD2 + more control over engine performance
1998- OBD2 + more control over engine performance & CTF network

 

The '96 model years started in '95 anyway... If they are out there, no ones ever talked about them here in all my ridiculous amount of searching.

 

I need someone to post a picture of their OBDII plug and also what to look for (#s etc.) to know if it has the CTM network or not.

 

CTM may have started in 98.5.... but, I am not 100% sure on that. 96 and 97 trucks won't have it. Basically, if it has the digital odometer, it's gonna be complicated. Mechanical odometer, and you should be golden.

 

Good call; if I find a 98' I will check for a mechanical odometer!

If it comes down to a 95.5 I will check for OBDII, assuming the following information below is correct for Dakotas:

OBD1


OBD2:

 

The shape is all you need to look at. Not every connector will have the same pinout... not even on the same vehicle line. Squareish is OBDI, rounded is OBDII.

 

I own a '97 Dakota with a 5.2L Automatic. Build date is 04/15/97. It has the digital odometer. I new someone that replaced his '97 PCM with a '96 PCM, he gained horsepower and torque, but the Dash Cluster was inoperable.

Now that I am in a position to do some performance upgrades to my Dak, I'm not really sure what and where I can go to do What I would like to do, maybe more HP Torque, upgrade Trans and Rear axle.

Any ideas would be great, truck has 140k on it. ( purchased new with 147 miles, I am only owner )

Please email me derekrtracey@yahoo.com for help.

Thanks.

sorry about that, i kind of ran two posts together. the initial reply was to help someone else with their question.

 

So much for the title...but now I'm really thinking if I'm going to do this I might as well make it a 360. Gas was a factor but if I was light footed I don't think there is much of a difference at all between a 318 and 360....it's probably just when stepped on or driven over 60mph?

If I kept all the regular 318 swap items in mind, what else am I branching into here? It's the same from the intake up correct? I can still use a 318 PCM/intake/everything? Block still bolts up like a 318? NV-3500 will fit with a 3.9/5.2 bell housing?
