Hey! So I recently traded my Miata for a project of a crv. I’m just trying to get an understand of everything that’s going on with this thing. So it’s a b18b1 block b16 vtech head with a switch for vtech wired straight to solenoid, has a emusa turbo kit. It runs rough and needs a retune. So that’s where I’m in need of help. This is only my second car(ready to learn) so can anyone give me some guidance on retuning it. Or tuning it in general. I see it’s chipped but no clue where to go from here.
