my ls crx doesnt get that good of mileage, maybe low 20s highway. i hate it. its got a chip supposedly but i cant find it. it says j-k tunig on the ecu cover. i took some pictures that i'll load up soon.

its gota code 43 which is fuel supply system. i see lots of people with this and now it could beanything? i'm hoping its the oxygen sensor because that would make sense.

if my ecu is indeed chipped is it easy to just take it out? i'd like to run regular fuel again instead of premium





here are the pictures of the ecu. i see no aftermarket chip.

No chip.
o2 throw there own code.
Thins i would check.
timing
ignition timing
and all fuel related things.

 

It is indeed chipped. See where it says SST. That's the chip theyre referring to.

Best thing u can do about your chip that is to get it reflashed with a known stock LS basemap and go from there. The ECU will not work if it is absent.

Try replacing your o2 sensor first and see if that fixes it.

could i also just swap for a stock pr4?

 

Yes u can.
