im doing a k20z1 swap in my 1988 civic dx hatchback im about finished. im getting ready to get everything to wire it and i am in need of an ecu. kpro is obviously the way to go but i am going to need a new ecu, meaning i dont have a core my swap didnt come with one. anyway i was wondering if anyone can explain exactly what i need to get as far as wiring and ecu choice, also what do i need to make my speedo work. i have an ef sir cluster and i think i have a high fequency transmission. the speedometer on my dash is not that important to me but the car running right is. any help would be appreciated also i have pics of my build if anyone is interested.

02-04 RSX engine harness
02-04 transmission
02-04 o2 sensor

this is wierd there are jumpers made for 05-06 to 02-04 and jumpers from 02-04 to my 88-91 and i was understanding the kpro can translate the vss isnt that the point of having the jumper for 05-06 to 02-04 why wont this work? why should i go sell my tranny and wire harness there has to be an easier way come on now money isnt a big issue why should this setup be?
