    im kinda new to the swap thing but i swapped a b20 into my civic gsr tranny running on a 00 ex ecu.. is the reason i can only rev 5k the ecu being the fuel maps are incorrect.. or is it some thing else .. motor stock can rev 6800

    You're probably tripping a VTEC error... the 00 EX is looking for a VTEC subsystem, and the B20 doesn't have one. Once you rev up to where your VTEC crossover would normally be, everything looks wrong to the ECU- so it's probably capping your max revs.

    In minnesota yea.. no salvage yards have any .. not even one.. i checked all the local posts nada.. and on here one guy has obd2a ls ecu when i need obd2b ls ecu due to it has different plugs and wont fit.. i have run my car on a b16a2 00 si ecu and still ran into the problem the only vtec ecu that i had no problem with was a mugen p72 with some other chip in it i dont know for some reason it didnt through my vtec code.. but any ways thats about it for now

    ps.. the mugen is my friends for his lsvtec .. and aint no way he is selling it to me lol
