Output Test mode - Idle Valve
hi guys my Idle valve seems to be working in reverse? When i went to the output test mode- idle valve when i clicked enable test run and set it to 0 my rpms went from 1100 to 3000, this is with the valve mode in "Normal, 0% = off" shouldnt my rpm stay the same? and only go up when i reach a certain number? (ie 26). Im following this guide to help me set up my idle: Mega Miata: Basic idle settings. and vise versa with the valve mode on "invert" where 100% = off. im trying to get my min/ max pwm % so i can set up the CL idle. Thanks guys!! my car is running a mspnp2 na 1.6 miata.

no. The way the idle valve rotates it can open back up under a certain value.
you're going to find you'll be running your valve between 25-60% PWM. values outside that range will just cause the valve to open 100%. |

Hey, I am also have trouble in idle.
I am sitting at about 600 when my NA likes 850. We know that it's running rich, seeing as how the AFR is at about 11-12.3. I've adjusted the AFR and VE tables, but to no avail. I saw that maybe it might be Accel Enrich issues, but I can't figure it out. How do you adjust the idle position? |
The idle valve position is adjusted by changing the idle duty cycle table (in open loop) or idle target table (in closed loop).
|
Gotcha. Is there anything I should be adjust in the base maps other than that and the fixed timing?
|
Should I be adjusting Idle cranking Duty step table? Idle Warmup Duty step table? or both?
|
Cranking duty is for startup, warmup duty is for running.
