Hey you all, can anybody tell me what kind of ecu should i run on my civic, its a 2000 civic with a 2001 gsr head, crv block, should i use an OBD1 or OBD2.

 

OBD1 with a jumper harness. In theory you can use the obd2, but you can't really tune it.

 

i have a datalog ecu obd1 pr4 with a tuned ls vtec program. tuned with b18b block and a 98 gsr head with i/h/e. 150$ for the ecu with the datalog cable and chip. if you already have a obd1 ecu get it chipped and either find someone that will give you a ls/v chip or buy mine for 10$.
