so i just got my three bar map sensor in, so i installed correctly and know the car won't run. I have a p28 with a hondata, and i think i installed it ok. I am guessing i have to have my tuner tell my hondata i have a three bar know and not the stock. Please let me know if this is the case.

 

never mind found the awnser on Hondata.com.

 

You have to get your chip reprogrammed for the 3bar otherwise it would throw you map wayyyyyyy off.

 

w0rd , go into rom editer and scal your map for 3 bar.

 

Yeah your have to reprogram. I run Uberdata and I had to retune the entire map again. You guys do this with Hondata?
