Default DPFI or MPFI?

tomorrow, im going to buy a 97' civic dx....of course it is a dual point fuel injection, but i was wondering if i should convert it to multipoint fuel injection. this is going to be STRICTLY for daily driving. Im lookin to see which is more economical. any help would be appreciated

Just get the car tuned. I can't imagine the fuel injection method giving you a worthwhile increase/decrease in mpg.

i dont know about pre 88 civics but i know that the dx model of civics from 88-91 were dual point and the hf/si were multipoint. the same went for the 92-95 civics. when i popped the hood of the 97 dx, im pretty freakin sure it was dpfi. like 98% sure

Aren't all Hondas from 88-91 Si and 1992+ all models, MPFI?

Do a tune-up with:

Spark plugs (NGK V-Power)
Ignition wires (OEM)
Fuel filter (OEM)
Air filter (K&N)
Clean distributor cap

You should be golden.
