Diagnostic equipment.......pics coming

It seems that nobody here ever mentions the use of diagnostic tools to trouble shoot these rigs. Is that because nobody has any or because everyone that has any diagnostic tools decided not to talk about them? Myself, I have a lot, and I could not imagine trying to get by without them. You would be suprised to see what is available out there and how much they help to keep these rigs running well and how easy it can be to find a problem with such tools. No more gussing as to what the problem is, no more tedious back probing at the sensors hoping that you don't damage the connector and hoping that you get a good reading etc. etc. Much of this equipment can be had for a reasonable price, and if you plan on keeping the rig then believe me, it is money WELL spent. On top of that, some of the equipemnt works for any rig, not just the EEC-IV system, thus furthering it life of service for you.

I'm all ears. What would be on your short list for the occasional D-I-Y fixer? Not looking for the latest SnapOn stuff if a lesser priced and quality tool will suffice for the occasional user.

I recently acquired a Snap-On MT2500 (aka "brick") scanner for a very good price that I've been using to diagnose issues with my truck. Sure I'm still limited with what I can see with it but it does help tremendously.

Did you mean for diagnosing tuning apps or for the actual tuning part? Work with SD?

I use a Digital multimeter, vacuum gauge, fuel pressure gauge, non contact thermometer, safety pins, and a few jumpers. With these and the wealth of info available on this and other sites you can diagnois probably 90% of the problems on an OBD1 system. The Haynes manual has a good trouble shooting section. A breakout box would be nice but I really haven't had any issues to warrant getting one. A breakout box mounts between the comp and harness and allows easy measurements without back probing wires.
The more advanced tools will give you more info for tuning and are easier to use. Being an old fart HVAC mechanic, I'm used to tracing out electrical and electronic gremlins. There are setups that allow you to use a laptop to view and adjust fuel maps and timing strategies.
