Honda B series Obd2a Wiring and RevLimit

[Koullisgg]

Hello everyone,
I would like some guidance.

I have a uAEFI board installed on my Honda EK Sir with a B16A. I’m getting weird trigger errors from the 1-tooth trigger. Because of that, I decided to ignore it after 800 RPM and basically use it only for sync.

I’ve been driving the car like this for some time, but today I decided to tune it for more power and raise the RPM limiter. The problem is that I can’t get past 7000–7500 RPM, even with all limiters disabled. This makes me think that the workaround I used is not actually working, and most likely I’m getting sync issues at higher RPM.

I’ve tried everything I can think of. The only thing I can’t find clear information about is the correct way to wire the sensor. Maybe it needs a resistor or some other conditioning before going into the discrete input, or maybe I’m missing something obvious. It could also be some hidden rev-limit setting.

If anyone has experience with this or can point me in the right direction, I’d really appreciate the help. Thank you.

Wiring is in default obd1 tune, i hope you have reset to that default

I suggest you ask on FB for happy obd1 uaefi or boostednw tune and log from anyone who has happy revs.
