to be honest you can tune 0bd0 just like 0bd1, its just that more can be done with 0bd1. spoon and mugen use to chip ef's, so unless your going all out with tunning it will just be better to stay 0bd0 but if you want you can also get a jumper harness to plug a computer up. and a 0bd1 harness wont just plug up without alot of rewiring!

just do the mpfi conversion and get a jumper harness (about $175) and youll be set
