Re: OBD2b - OBD1 Conversion & Tach doesn't work
I put a Hondata s300 in my 2001 GSR (installed in an OBD1 P28). Everything started up fine, but the tach did not work. The car was running, but the tach did not work at all. I pulled the Hondata unit out, threw in a stock OBD1 P72 and the same result occurred.
When the S300 was in the car, all the datalogging was working. RPM, Vac, etc. all were working on the display in the laptop. The gauge in my cluster just sat on 0. All other gauges worked: Temp, Fuel, Speedo. The tach just sat on 0. Pulled everything out, and put the stock OBD2b ECU back in, and everything worked fine.
The GS-R is SC'd and running the JRSC hack and FMU. It started throwing the code for the Atmospheric sensor. I picked up a Hondata S300 and was going to put the unit in and run a stock P72 map in it (still running the JRSC hack) until I can get the cash to take it to the tuner. Now, seems like I have other issues.
Any suggestions?!
