Hondata

having issues with my 8th gen si, im new to flashing car with hondata and still learning. mods done to my 8th gen hybird racing CAI and megan racing headers, i tried putting a base map calibration that would best fit the car but for some reason my idle is surging. would really appreciate the help or pointers so the car can drive good. thank you!

Post the calibration file you are running and a datalog. Does the care only surge when you flash with hondata? Did it surge before?

Ok ill post it later when I get a chance but yes it was doing before and I thought it would've stopped when I flashed it

If it was doing it before it could be a mechanical issue. Did it ever not surge? Did you change something and it started to surge?

-Ed

Yes it didn't surge when I loaded a map on it with the hondata but then when I went to start it the next day it was surging again

Return the car to stock by removing the flashpro. If the surging continues than you need to look into mechanical issues. Is the car throwing any codes?

-Ed

Is there a way of contacting you different so it can be quicker?

You need to post the actual file and datalog to the forum.

-Ed

The car is showing two codes.
P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

P0507 - Idle Control System RPM Higher Than Expected

Look up the codes and fix those issues.
