As per my other thread, I have installed the MS2 and got up and running, even went for a couple of quick Autotune's.
However, I have cold start and idling issues. Now, I think the cold start issues are linked to the idling issues so let's start there.
I have read THIS GUIDE
from MX5Nutz start to finish, which is a bit pointless as my car fails at the first hurdle.
I select Idle Control > PWM Valve >Open Loop Warm Up. Start the car, it idles anywhere between 2k & 4k RPM
I go to - Test IAC - Steps =100 - Enable test, if it isn't already idling high it shoots up to 4000 RPM as per the guide. But then when I start to walk down, by the time I get to 97 it drops down to idle between 1000 and 2000! WTF!? Therefore I can't find my values to plug in to the next settings table.
If I click 'stop testing' it shoots back up again. If I click 'enable test' sometimes it shoots up, sometimes it dies down to 1000 or so.
I have tried inverting the valve settings I have tried copying numbers of the internet but nada. Nothing seems to work.
It's annoying as 1) I have to manually idle the car with the gas pedal from cold start and 2) once it is warm it idles fine and can be taken for a drive.
There must be something obvious I'm missing here.
Any help would be greatly appreciated.
I have searched and searched and searched and read up on ASE & WUE but I don't think I'm even getting that far...
If I hit the gas pedal as I am cranking it (as I do in most cars anyway) it starts within a second or so. The issue then is, I have to keep my foot on the pedal to keep it idling, if I lift my foot it drops to about 500RPM and stalls itself out running mega rich.
In an attempt to resolve the issue I 'tweaked' the ASE & WUE that much that my WB was showing AFR's in the 10's and the car stunk of fuel and was miss-firing, shaking like a sh****g dog and still cutting out when I lift of the throttle. I reverted back to some Braineack settings I found during research.
