Re: Running like shit when cold
I think you miss understood me. I did not say that you tune the car at diferent air temps, but that the air temp afects on how much fuel you will get. If and only if, anyone have fucked arownd with the corretion values, it will make the car run like shiet when cold.
Take it as you want, it makes no difference to me. |
Re: Running like shit when cold
PV = nRT
n = PV / RT P = pressure (MAP sensor) V = volume (displacement / 2 * RPM for our motors) R = ideal gas constant T = temperature, i.e. density correction The whole point of ECT and IAT corrections is to control the impact of temperature changes on AFR (and timing). The idea here is that you approximate the temperature (i.e. density) of the air going into the combustion chamber by two sensors you can read, instead of putting a sensor in the combustion chamber that has infinitesimal measurement delay and total accuracy. The stock ECU routines were setup by honda's lawyers to run the car with 240cc injectors. When you put larger injectors in a car running on OEM honda code (Uber, Crome, etc.) the magnitude of the corrections is totally innapropriate to do anything other than cause chaos. Additionally, our lovely honda engineers saw fit to use different correction tables for open loop, closed loop, idle, ... ... The code is horribly obfuscated. Mark my words, me/Calvin/Damian will get to the bottom of this mess soon. I know I'm an ------- a lot. I just don't like arguing with people over things they're wrong about. |
