Idle issues on my turbo miata /w megasquirt
Hey
The idle on miata is about 1000rpm but when i give it gas and on the down motion of the rpm needle, it likes to sink to 400rpm and sometimes even stalling on me. Anyone know what could this be? Tuning on the megasquirt? The throttle body?
Thanks

Is your closed loop idle control on. If it is, you may have to adjust the settings. You may also have to tweak the idle screw on the throttle body to get it to idle at the rpm you want.
Another trick is to slightly enrichen the cells in which your idle rebounds after a decel. This aids in the idle recovery. Post your msq.

Any monkey can change parts...a true mechanic makes a diagnosis.
I seriously doubt your throttle body is going bad...stop taking your car to those monkeys.
Another option is to do the BMW VTPS (variable throttle position sensor) mod...which allowed me to get rid of my idle droop (and dying).

I picked mine up cheaply...and was a cinch to install and calibrate.
Besides this there is just managing the enrichments of those cells.
Also, when you run datalogs MLV will change those values around on you, so write down a little table of the values you get to work so you can change them back.
