OK, I just got B16A2 (OBD1) engine put into my Civic Hatchback '97 (was OBD2). I had to use all wiring from OBD1, since one I had was not good (I had 2 connectors to ECU, fired injectors in pairs, etc, etc.. - European model, D14A4 engine). Anyway, what I wanted to ask - I just noticed that for tachometar it states in service manuals that for year 96-98 200 pulses per minute are equal to 100rpm, while for 92-95 it says 250 pulses are equal to 100rpm! So, I guess due to this I'll have wrong reading of tacho? Anyone had this issue?
