holy crap...please learn to spell and use complete sentences.....i have no idea only i understood is you have a 95 ls with an h22 swap vtec isn't working and you bought a vtec controller thinking that would fix it...

yea my bad i as in class and i had the teacher behind me so i was rushing. but yea i had a 99 ls with a few mods and i traded it for my now 95 with a h22 swap. the h22 is ran to the ls computer so i do not have vtec. i have a vtec controller that i got off of a friend and i printed the wiring schematic of of the internet. i still have no idea how to hook it up or if it is even gonna wk. so if anyone knows how i can hood my vtec up without having to but a new computer and ecu please let me know because i really want to run the fool potential of my motor.

urm...i assume just a h22 ob1 ecu and plug it in and it may work...if not get a p28 with s300 and put a h22 base map on it.....

Wait... What?
i would have rather had the ls.... instead of an older car with a swap that wasn't done right

well if i were you i would definatly get the correct h22 ecu for your car, i believe it is a p13. that motor is alot bigger than an ls and the fuel maps, timing, ect........ are completely different. i cant even believe that motor is running at all on that ecu, get the right ecu and you will be happy. a vtec controller wont fix your problem.... there are two wires that you need to run to your ecu to make vtec funtional, here is some hard to find information that i hope will help you out. This ecu pinout diagram below is for a p13 prelude ecu and will not work with the ls ecu you are using.

run wire from vtec solonoid to pin A4 on the ecu(ECM-A)
run wire from vtec pressure switch to pin D6 on the ecu(ECM-D)
