I know this will sound stupid... lol... i know I'll get **** for this post... I am doing a ls/vtec swap. I dont have a obd1 and I need it for the swap. my civic is a 97 lx do I Need the obd1 for the car to run, btw its b18c1 head and b20 block. and how much will it cost me to get a obd1 and can I find one at a junk yard.

 

okay first off your building a crvtec not an ls vtec since your using a b20 block. and if you want to go to obd1 just use a jumper.

 

Bump any one else with advise? still wondering if it would run/start up w/o it

 

start up without what?? do you even know what OBD stands for?

OBD1 ECU
OBD1 engine harness
OBD1 conversion harness

and no, you cannot start an engine without an ECU

not to be a complete dick but you're putting a frankenstein motor in a car and your unsure if your car will start without an ECU?

 

If its not built use the GSR ecu. If its built convert to obd1 with a jumper harness and use a tuneable ecu.
