I have a stock 94 civic ex. I am giving it to my nephew (car is beat up) but want to keep the p28 for later. Is there a cheaper, easy to get ecu that will still work okay in the car that I could swap the p28 for. Even if the vtec no longer worked I wouldn't care. He won't either, the car is free for him.

 

these ECU's will work on the car BUT nothing works better than the original ecu tho'

P05: 92-95 OBD-1 Civic CX
P06: 92-95 OBD-1 Civic DX
P07: 92-95 OBD-1 Civic VX
P08: 92-95 OBD-1 Civic D15 JDM
P0A: 94-95 OBD-1 Accord EX
P13: 93-95 OBD-1 Prelude Vtec
P14: 93-95 OBD-1 Prelude Si (non Vtec)
P27: 92-95 OBD-1 EG JDM Civic 1600 sohc
P28: 92-95 OBD-1 Civic Si/Ex
P30: 92-95 OBD-1 DelSol DOHC Vtec Si/EG SiR
P54-G31: 1997 Honda Accord 1.8 LS
P61: 92-93 OBD-1 Integra GSR
P72: 94-95 OBD-1 Integra GSR

 

P28's are not terribly expensive or difficult to find. If you're that concerned about it, just ask your nephew for $50, and leave the ECU with the car for him.

 

Came through again with some good advice. Are they that cheap? Seems like they are more like 250-200 dollars everywhere I look? Maybe ebay just sucks ***. (it does)

 

I see them selling for around $100-$150 in the Markeplace. Factor in the cost of buying the replacement, and you aren't really saving much.
