So Ive been thinking about buying one of the DIY kits and having a family member assemble it for me. Ironically its 52 pin plug fits both of my cars a B6T CAPRI XR2 AND MY F2T MX-. Would I be able to load 2 seperate tunes and run it in either car? Id probably use a Miata Turbo map as a base, Anyone have suggestions?

The tuning software sets up different cars as projects. You can have as many projects as you need.
However, the MegaSquirt will only hold one set of settings at a time. If they are exactly the same configuration, I could see it working.

I believe you can run 2 tunes on the same MS... was done for people running e85... not sure whats involved... but I know it's an option
the real question is... is the electronics IDENTICAL... same impedance injectors, same dizzy design and wiring... if there is anything different then the internal wiring would need to be different for each setup...

^The newer MS units handle map switching, in other words a high/low boost map setting.
Why wouldn't that work for two different vehicles?

I've never built a DIY PNP, but basically the kit is a Microsquirt and a plug that fits your car and you jumper between the two depending on what car you have. SO I would think unless both cars have all the same hardware AND the exact same pinouts to said hardware on the plug that currently goes into the ECU's it won't work for both. You could build a boomslang for one car to make the pinouts match up, but it would be easier to just buy two DIY PNP's. I have installed the same MS1 in 2 different Miatas (93 Cali version and a 96) and the main changes were in the pinouts mating to the car's wiring (even on 2 VERY similar cars).

While the DIYPNP has table switching, it just switches the fuel and spark maps, not the entire settings. And the build is going to be a bit different between the two cars as well.
While the pinouts on the XR2 and the F2T are similar, they are not identical, so the two could not be run with one DIYPNP without changing some of the internal jumper wires. The F2T uses a distributor with a Nippondenso type dual wheel setup, while the XR2 has a mechanical / vacuum advance distributor where the ECU has very little control over the ignition timing.

... could always goto edis on both... but at that point it's not very PnP
