Hondata

Excellent and helpful answer. Thank you very much!

So what you are saying is: on my ECU with it's OBD2A connector, I would wire the Wideband to D16. If my ECU had an OBD1 connector, I would wire it to D10. But on my ECU OBD2A D16 is electronically the same as OBD1 D10, right? I think it is, which DOES make D16 a valid input for THIS particular ECU ...

So even though my Hondata ECU has an OBD2A connector (meaning that I don't use any adapters between my stock '98 civic EX OBD2A wiring harness and the Hondata ECU), I don't use D16 instead of D10 as per the attached chart? That is odd because I am definitely running Boost Control on A7 instead of ...

See the blue highlighted text below. When would it be appropriate to remove R136 and R138? I have a Hondata-modified S300V3 ECU with the OBD2A connector, so I will be coming in on D16. Does that matter with respect to removing R136 and R138? I want to be able to run closed loop with target AFR ...

This is a great question and I haven't seen a good answer yet. I want to do this with my trackday '98 civic.

For the activation input, choices are:
Always on ...Under what circumstances would this be chosen? Wouldn't this be just like an always on rev limiter?
Air Conditioning Switch...I still have ...

Sorry, that schematic may have not shown up. Lets try again.

Does the CPR use a 5v signal to fire the coil?

Can you tel me more about the interference concern? Thanks!!

I have a set of these GM LS2 Truck coils that I'd like to try. They are actually "coil near plug"
(needs to have a short lead). I will make a bracket to fit these above the valve cover on a turbo D16Y8.
Based on the schematic below, would they work? In this case, the sequencer would be the CPR ...
