Current setup: 4AGE stock achey-breaky thermo-pneumatic IACV with coolant ports blocked off for reduced IATs. High idle when warming up, settles down after it's been at full operating temperature for a while. MS3X can only influence idle slightly via ignition timing.
Proposed new setup: IACV blockoff plate (Warning: NSFW lyrics in video) + some kind of 2-wire PWM IACV to minimize ECU pins and additional electronics needed (maybe Ford? Want something from a common modern car, preferably Japanese for ease of local sourcing). Set full-time closed loop idle to compensate for AC and PS loads (since the blockoff plate eliminates my current PS idle-up system that works well) as well as warmup variance. This should work well with big cams + ITBs in the future.
Any flaws in my plan? Any good candidates for IACVs?
