tech2 use?
I am thinking about buying one, not for a vette though but a 97 f car. Wondering if anyone has any input on using one, I have been trying to figure out a p0300 random miss detected.
So asking here to see just how in depth one of these can go to more pinpoint my problem as well as what other things can it do?

Most OBD readers will give you the specific cylinder that's misfiring (the DIC only shows P0300's). The better readers will give you the misfire counts per cylinder so you can determine if it's a single cylinder or a general engine issue.

The TECH 2 is VERY IN DEPTH and will let you do a whole lot more than you care to imagine.
You can operate a single bi-directional component or conduct whole test of the PCM & BCM plus other modules.
Check out this TECH2 OBD PDF users guide. Kind of a holy grail of TECH 2
This is all the commands that you can do:

Google TECH2 training and you will find a users guide that you can down load. Its a basic users guide that will show you how to use it and what it can do but, it will NOT show you all the steps that you need to get to a SPECIFIC TEST.
Thats where the PDF I provided will step you thru. It works backwards. Figure out what you want and it will show you all the steps to get there.

But, I have heard a tech2 can read exactly which cylinders have miss counts. This is a 3800 series2 so cylinder misses can get real expensive real quick for it's ignition related stuff.
I have 3 of these f platforms so if a tech2 costs me around 600 bucks it will be well worth it in the long run.
So I need to see exactly which cylinders the pcm is seeing as randomly missing. Yes the car has had tune up the big enchilada and passes all vacuum tests, coolant pressure tests etc etc. So not mechanically related problem.

I understand the abilities of obd2 and p0301-306 etc. That is not what my car has though, mine is showing just p0300. My scanner can pull all codes but my understanding is random can mean at least 2 cylinders must be randomly missing to set this code.

The misfire count is what you need to see.

Can you reset fan temps as well with it, I assume pmc flashing would have to be dealer done. One other odd thing this car does is after new engine was put in the RPM governer never worked again. Basically it used to cut the fuel at around 4,000rpm if reved up in neutral.
I have also heard my issue might be crankshaft variation relearn related but at same time heard this is supposed to happen automatically but then heard some cars do it some don't.
I have also read up on the knock module which is removeable from the PCM might be the problem.

I have a friend who wants to sell his, he wants 800 but yes I know what they generally go for but my cars these days are obd2 so no matter what the price it will come in handy.
