I have a 1995 Honda Accord EX Auto. My transmission went out so I bought a MP1A and it HAS LSD. I was wondering if anyone knows the gear ratios for this tranny so I can calibrate the speedometer? Also should get an OBD1 Prelude TCU and if so what will that do differently than the stock Accord TCU I have now?

Thanks in Advance for any help.
