Great feedback, guys - seriously appreciate all the insight.

I’ve already learned a ton just from this thread, and I’m really glad I came here before smashing the buy button. It also helps knowing there are a couple Haltech tuners in San Diego, so local support won’t be a problem.

I ended up spending the evening digging into COP setups. Looks like the R8 red coils are really all I need is 12 for the twin setup, and they’re surprisingly cheap. Not sure why my brain was still hanging onto the CDI idea. With the R3 handling PDM and sequential ignition directly, the smart coils plug right in without needing separate ignitors. Definitely simplifies the whole plan.

One thing I’m still on the fence about is the wiring harness. How daunting was it for those of you who built your own from scratch? I’m debating whether to tackle it myself or hand it off to a pro. Would love to hear what you guys experienced.

@zaphodtheprez great tip on the quick disconnects. Gonna look more into Map and IAV. You guys have planted the DBW seed in me. My small brain thought brake boost hose can connect to vacuum manifold? But research also indicates ITB vacuum isn't strong enough. some owners run a separate vacuum pump, noisy?
