B20 and ECU

i know everyone says when doing the swap its ideal to use the LS ecu then do the OBD change over from OBDII to OBDI

wouldnt this cause a problem...the computer thinks the motor is still a 1.8 liter than a 2.0? how would you get around this...or does it even matter?

I know a person who has this setup....b20 in an EG with an LS ECU, and who did the OBDII changeover to OBDI by changing the dizzy, injectors etc and it runs like a champ.

Ya, i've chipped several ECU for the B20.
You can even run a stock Civic DX ECU with the B20 program in it.

I'm running LS code with the fuel maps scaled to 2.0L. Runs well enough until I can tune for my setup.

Let me know if you want a copy of the ROM image.

would i be better off doing that over changing to the P75 ecu...and get the same results

if flippin CRV's came manual this would really cause less confusion

B20's came out in 97 - there are some manual ones, but all ECU will be OBD2, which won't plug into your EG - and would require a LOT of retrofitting to convert it to OBD2.

You're best off chiping your stock DX ECU, or running a P75 (P75 will run just slightly lean under WOT).
