will 88-91 prelude ecu work in 88-91 civic if so what kind of gains if any

 

i was also wondering this also....since that ecus fuel maps are to run a 2.0 liter engine.....i was wondering would it help out on say....a b20 non-vtec swap....bump for more information!!

 

i'd say no.

civic/tegs are "interchangable" in words of electronics.

and

prelude / accord are interchangable the same way.

 

well, it is not the car it is the OBD of the car....when i put a F20B OBD2 in a 1999 accord, i used a 0BD-1 conversion harness..and a P72 Ecu....GSR ecu in accord on accord type-r motor, fired right up and runs strong.........the firing order is the same, the electronics are the same!

 

so i guess i just need to try it

 

bump

 

The point is: It should, I mean... we really need more info. I dont see why you would want to do it. If you have the stock engine and the new computer is putting enough fuel in for a 2.0, you probable will loose power. Just becuase you have more gas doesnt mean you are faster. So I guess it would work, it just wouldn't be the ideal situation. like dadilus said in the other post, as lond as the obd's match, I would WORK. Just not perfect.

Dadilus: Yes, as long as the dizzy and all are obd0 also.

 

yeah i just happen to work at a shop when i have the time...i get to experiment, and play with all kindsa ****....that f20b swap into the accord was the most painful swap EVER!!! i hate OBD-2 cars and there immobilizer)(@*%&#
