I thinking of rebuilding my hf motor and I was think would i get better mpg if, I convert to obd1 and what ecu would I be able to use to run my hf motor? Any help would be great just picking your brain

so nobody on this entire forum has any useful information about my possible project.


well thanks for nothing

 

wouldn't matter the cx gets the same gas mileage, and that's the closest obd1 motor to match the HF. just a well taken care of the motor, tire pressure and adjusting the nut between the gas pedal and driver seat dictates how much gas you are going to consume. I have a 2k camaro ss and get 27 mpg and my father gets 18 mpg. My crx i get around 34 (DX with Si motor/trans).

 

Just rebuild your D15B6 and stay OBD0!!!

I want to get close to 50 or more. I get 38 in my dx with dx tranny. and i want more

 

you should rebuild it, then stick a Air/Fuel gauge and SAFC on there and go to tuning that bad boy down. I know someone with a 2000 Prelude SH that's getting 40MPG when driving easy thanks to the VAFC.

 

50+ would probably require tuning, weight reduction and distribution, and trial and error. some things I would start with is relocating your battery and having plenty of tire pressure and a thorough tune-up. certain types of spark plugs/wires/oil/ etc may effect it a little also.

 

Do some research on HHO gas fueled cars. I have an friend in upstate NY getting 60 MPG average from a 92 Caravan. The HHO systems work better with the older efi systems anyways. I bought an 88 EF sedan and that is what I'm going to do with that car. My thoughts are: 92 Caravan average mileage 18-20; Caravan on HHO= ave. 60 MPG; 88 EF ave. 35 MPG; 88 EF on HHO gas=100 MPG. I don't know for sure that is purely speculation. I am going to be gathering the equipment to make the system and installing it when I figure out why the Civic is not getting spark.
