okay so heres the FULL rundown.

1. im doing a top-to-bottom rebuild on my B16A2, and I plan on going stand-alone ecu just to future proof for boost, The ecu of choice is the fuel tech 550

2. im getting a Tucked engine harness for said engie that is full obd2a plugs (engine side) but the ecu plugs are obd1

3. IM wondering if i could get away with getting an ft550 to obd1 jumper harness just so i dont have to use an obd1 to obd2a jumper harness (obd2a engine plugs but ecu side is obd1)

3.5. i say obd1 to obd2a because i have the option to get either ft550 to obd2a or ft550 to obd1

4. What sensors or features would I be robing myself of by going OBD1 ecu side?

if what im saying makes any sense, i would appreciate any help
