Hondata

Hi Eficu, having done (i think) all the mechanicals and sensors checks that could cause my stock R18 honda civic 2007 to run rich all the time and yet finding none, I think I am now ready to go the Hondata route to recalibrate my ECU and resolve this issue once and for all.

Please how can I get ...

Suppose I have a mechanical issue like worn piston ring that causes a rich fuel trim, can I use flastpro to adjust my parameters such that my engine runs efficently?

Eficu

OK, thank, If the flashpro device can fix my rich fuel trim, then I need to buy it I guess.

Hi Eficu, I am not running flashpro, dont even know what that mean, my car is stock about 200k miles, I ask this question in the flashpro section becuase I coudnt find an Honda civic section in this forum, sorry about that.

Please help me, my fuel trim is always negative, it bothers me, I get -14 ...

Hi Eficu, my 2007 Honda civic EX stock R18 engine always have high negative fuel trim, both long and short term . around -14 and -20

So far, have clean the mass airflow, checked the 02 sensor and it is ok, change the air filter to a new one

Please what should I do to solve this problem.
