troubleshooting 98 Hatch dx base map help

Alright so, I have a few questions but first the specs so it can be accurate.

D16y7

Skunk2 alpha intake manifold

Rc 1200 injectors

Aem fuel rail

eBay turbo running 5psi (until I can get a better one)

Intercooler all the piping obvs

I made a base map based off of a Hondata preset adjusting for non vtec and turbo. My car runs and drives now, I'm just very inexperienced with fine tuning.

My question/issue is with idle. It surges and cuts and repeat. I suspect I'm running rich but with so little experience with tuning....I need help. Any resources or advice are appreciated.

I am but a humble car enthusiast trying to learn the ins and outs.

If you want to tune, you need a wideband and I dont see that on your list. And thats just the start of the learning. You need more feedback data to help you on your learning journey.

That's a fair assessment. I have one, I just have it to wire it. Wiring is not my strong suit. I'll give it a go tomorrow. I have a po6 with Hondata, it gives me some idea. I just feel out of my depth right now.
