5G ECU Q: Can you use a 97/98 ECU in a 99+ model Prelude?

Anyone know if this will cause a problem?

 

I don't believe that you can. There was some changes in the connector during the OBD2 vs OBD2.2 that will cause some problems. Though I'm not ECU guru, this is off recollection of past threads.

 

bump for more answers

 

No, you cannot. Changes in the evaporative emission control system prevent it.

 

awww snap, I just bought a 97 SH ecu for my 2000 SH. What am I gonna do now =^\

 

sell it on E-bay?

 

are you people saying that you can't do an obd2 to obd1 conversion on a lude ?

no

they're only asking if you can use an earlier obd2 ecu with another obd2 vehicle

 

can it be possible to use a ecu from a 99 lude on a 97 lude?

 

i'm currently running my 97 base, on a 99 base ECU, works fine so far

 

thanks
