Hey man ! Nice crazy build you've got there.
First, ditch the 95 computer....its the most temperamental one to choose from they don't like modifications. The easiest computers are from 89- 93. The emissions stuff can all go. The 94-95 actually do some funky stuff with the Ignition module on the distributor, that tfi module isn't compatible with earlier computers. Pins 11, 27, 31, 32, 33, 34, 42, 48, 54, 55 and related wiring could all be deleted and the car would run decent. 27 and 33 are for EGR and I see no real reason to delete them. Without being there its hard to tell what you can delete entirely. The wires running to and from the components listed can be deleted. Pins 8 and 22 are where my knowledge stops. 8 checks for a signal from the fuel pump relay and 22 is the ground for the FP relay. I don't know if the computer needs that signal to fire the injectors in a 95.
A stand alone would be a lot easier for what you're doing....but looking at your build it doesn't seem like you're the type to take the easy way out. I use mspnp2 for my car. I have some more detailed info...I'll try and post it tomorrow.
Sadly you are very right ahah, the easy way seems boring and expensive ahah
as for them being tempermental, i wouldnt know yet!
the bigger issue im having now, is now that ive unwrapped the looms, im curious to what keeps the voltage for the maf and the IAT, is it the ecu or are there a set of resistors somewhere i need to keep intact, as i havent seen any just yet
