I was looking on fueleconomy.gov at the 1987 Honda HF and noticed there are two versions. One being FFS and one without that designation. I read that FFS is like a feedback system on the carb that meters the fuel like later fuel injection. But what I wonder is why there were two versions in most every year of the CRX? Do they follow a California/49state difference like my Honda VX? And finally, how do you recognize the difference if you are shopping for a CRX? On the fueleconomy.gov, I see the FFS is much higher in MPG.

Thanks
