Does the VIII pcm support live data?

i dont know why some one hasnt or tried to make an adapter to plug in to the EEC IV and convert the signel to OBD II so you can use an OBDII scanner. i bought an OBDII tool for my PocketPC and it came with a converter box that plugs into the OBDII port and the comport on the PDA and a program for the Pocket PC. Seems like teh same prinsiple would apply
 
I believe the biggest reason is EEC-IV is mostly analog and OBD-II from what I know is mostly digital.

I have a breakout box for the EEC-IV but haven't had time to tinker with it. I also have a Rotunda monitor-recorder, but apparently there is another black box(monitor?) that needs to go with it to use it.

I need to scan eBay for one of those Snap-On tools.

Or buy Tommy's. :D
 
I e-mailed tweecer he told me that the site has'nt been updated recently and that my comp. dza1 and my brothers w3z3 (94) were supported. I did'nt ask about others. rec e-mail w# to find out. anyone used tweecer seems like the hot set-up!

JP, I dont have the MT2500 I used to "long term borrow" one from a mechanic friend of mine.
LUCKILY I didn't have possession of it when my car got stolen..

BUT..with that said a few years ago, I got the Rotunda Monitor off ebay.. so.."your in luck".

Having a BOB/Breakout Box is a good deal as well.. it's FAR better for checking the sensor voltages because it adds no additional resistance into the equation and you have direct access to the actual feedback coming from the senor.

You need to be fully aware, that these tuning solutions have a completely VERTICAL learning curve.
Tweecer does have decent support..
BUT. there aren't many folks that will be able to "teach you to tune"

..I'm not saying your not capable or that you cant learn.. just be forewarned it's a fairly intensive deal your about to get into.

When I first started looking for tuning stuff, I didn't really realize how important datalogging would be, nor how nearly impossible it was to datalog and EEC IV...

Literally nobody wants to support that old PCM platform, none of the new "cool stuff" works unless you have OBD2.

I went with the SCT software because I at the time felt it was the "best solution" for my tuning needs, without realizing I was stacking the deck against myself with literally no way to datalog the car.

For most near stock applications datalogging MIGHT not be so important, but the moment you have an "issue" or need to tune a blown or heavily modified combination you quickly become limited in what you can do without any way to datalog.

Hindsight being 20/20.. I would have
A: gotten an obd2 car from the start.
B: gotten tweecer for tuning my eec IV car

The value of datalogging in tweecer vastly overshadows any limitations that software may have compared to SCT ProRacer.. While the SCT software is probably "better" there is no viable means to datalog the results, which becomes an endless game of "trial and error".

..sorry for the novel.. hope this helps
 
I'm really glad you guys jolt me completely awake from time to time.
Last fall I bought an AutoXray AX6000 scanner to work on my 86 F150's TFI module.
I figured with 2 Marks and the truck all being OBD-1, I'd better get one while they
are still available. Until this thread, I never noticed that you can "view live sensor
data & engine controlled values from vehicles on-board computer".
They also include XZ-PC AX500 software to archive/graph data in spreadsheet format.
This is a combo OBD-I/OBD-II scanner unit, so I hope "live date" works in both modes.
They are currently on "that auction site" for $260.

Tommy - your comment about Tweecer vs PRP has me in a tailspin. After spending
the winter getting the truck into tow-vehicle condition, I'm just getting back to the
Mark/Vortech project. When I left off, I had just ran into the problem of instrumentation.
I started with fuel at too rich to run, backed off a lot, but can't really tell how close
it's getting without widebands. I looked at PLX and Innovate, that in turn led to data-
logging considerations, then you drop this Tweecer bomb. Do I fish or cut bait, continue
with SCT or jump to Tweecer???? My head hurts!

Mel, any serious tuning..such as forced induction, you are going to have to have wideband first and formost.

Tweecer has a decent platform but it's vastly different than using the sct stuff.
There is a pretty huge learning curve either way.

If your "knee deep" into SCT I dont really see a reason to cut bait..

stick with the SCT, get WB02 on the car..

most decent WB02 solutions have some form of datalogging software or hardware. With that said.. "dont ask me which one is best" because that is one hurdle I have yet to jump. I was "right AT" getting WB02 on my car and that project simply vanished/evaporated.

With that said, you might/likely will need to seek some professional help with your forced induction affliction and the subsequent specialized tuning needs.
 
i too was looking into the twEECer RT set up for my 94 mark. i figure $550 for the set up would not be bad to be able to read codes, tune my car, and have a full set of real time gauges with out going ricer and sticking them everywhere. i already have a lap top that i can use to put the program on. the thing i like best about the tweecer is the switch on the "chip" so you can have 4 different tunes and if they all suck you can turn the tweecer off and revert back to your stock tune to "limp" it back home. that would be really nice option on a nitrous car so you could have nitrous tune that was super rich and timming pulled out of it for the spray then a "lean" tune for driving to work on the street for gas millage.

i do have a question about the tweecer though will it allow me to change my trans shift points or is it just for the motor?
 
i'm no tweecer expert by any means.. but I'm pretty sure transmission functions are also included. pretty much if the PCM can control it, tweecer should be able to access it.. for the most part.

That would probably be a better question for Mike Glover, the creator of Tweecer.

Had I known I would have had such an issue finding a datalogging solution for the EEC IV using the SCT software.. I probably would have gotten the tweecer.
Considering Tweecer is a considerable amount cheaper than the Pro Racer Package that I purchased.

now that I have obd2 car, I'm glad I didn't go with the tweecer.
 
I just want to say this is a great post guys.

I have learned alot from it. Now im tempted to get a laptop. Curse you
