whats good honda-tech. i got a 90 ef si. i currently have a Ls swap in it. it have the wrong ecu currently on it. im running a spoon b16 ecu. im running it like tht bcuz i was goin to do a Ls/Vtec, but winter hit to soon. and wit this ecu my car doesnt run sufficient. What kind of ecu should i get for it besides a stock one?

 

Obdo or obd1?

 

Pr4

 

the engine is obd1

 

there is no ecu that is better than the stock obd1 PR4, unless you use a p72. Why use a b16 ecu when b16's run a different fuel map for a 1.6L motor? I know people that use the PR4 with b16's and have them chipped for vtec and like them better than the stock ecus.
