I'm getting a code 19 from my car. Code 19 is the automatic transmission lock up solenoid valve. I just got this ecu so would a automatic ecu do this to my manual transmission civic? Please let me know thanks.

 

answer: yes the automatic trans computer will not only make your check engine light come one but i believe that the air/fuel curve is slightly different that that off the manual transmission one, and to add to that i also believe u have like 500 less rpm on the rev limiter. so not only is the check engine light gonna kick but u also lose power and gas mileage, and if your in california it might hurt a lil bit, good luck. by the way your car will still run fine, just not to its potential.

 

not to mention, if you have a vtec motor, it will not engage due to the CEL.
so get the right ecu.

 

Yeah I just finished converting it to manual. Only thing I noticed was that when I floored it my A/F ratio on my plx goes to mid 15's then a second or two later it goes to low to mid 13's. Does converting auto to manual do this or is it just my lower compression vitaras?

 

you can convert the ecu. I believe there is a how to on hondata's site.
