That's not really tuning, but a similar hardware interface is usually used on the EEC-IV.
Check out moates.net, and look at the J3, F3, and QuarterHorse. Those are currently the state-of-the-art for DIY aftermarket tuning solutions, IMO. However, you MUST have a PCM that is supported by the software required to run these hardwares!!! So check with the websites for the latest supported PCMs and strategies FIRST. If yours isn't, you'll either have to write one yourself, or convince someone else to write one for you; I won't, because honestly I don't have the time for it. In OP's case, it's probably easiest to change over to a well-supported PCM like an A9L for MAF, or a C3Px/ICYx Lightning PCM.
Before doing any of that crap, why do you need tuning capability?

I've wondered if there was really any benefit from programmer like tuning units in our older vehicles. I figure that the older OBD1 and even the older OBD2 units that were not so heavily controlled by computers were easier to tune by hand and basic mechanics tools. Again, I'm kinda new to these units that have even the basic controls that are the OBD systems. I mean, with our trucks, we can set the timing, upgrade components and make adjustments as we need too. Now in my newer OBD2(CanBus) system in the Ram, I have a programmer that makes adjustments to all those things since I don't have a distributor or anything now.
