D16y8 with all basic bolt-ons and Phearable.net OBD=1 conversion. i'm getting like 200-220 miles per tank. That's only like 21 mpg! Anyone else having this problem or know of ANYTHING that might be causing this?? Any help would be great!!!

 

spark plugs, distributor cap, distributor rotor, fuel injectors, tps(throttle position sensor) sensor, o2 sensor. depends how many miles on motor they all could be worn and all be taking away the gas milage.

 

Thanks for the suggestions but all have already been checked and serviced or replaced. I did the OBD-1 conversion because my secondary o2 sensor went out and it was going to be like 300 bucks and the conversion was only like $180 chipped p28 ecu, harness and all. Still have no clue why it could be killing my tank like this......

what chip is in it?

 

It's just a basemap Phearable tune specifically for the mods to my motor. Should run fine but who know's why... Just found out my alternator is only putting out 30 amps when it should be like 65+ so now i've gotta replace that.

 

had the same type of problem with my gsr. was getting 20-22 mpg. I had a "mugen" chip that was just dumping in fuel. apparently all sensors were disabled. I replaced the chip, had a base map put on and now get 29-32. quite a difference when gas is $3/gal

 

Yeah it sucks spending all this cash dumping gas in what is considered a "gas saver"!! It's also really hard to find anyone good to tune where i'm located.
