Hondata

Hi , I am trying to wire a manual switch for Datalog, but it is not working
I connected the switch to AC signal and after to brake switch and I earthed the switch, but still Datalog is not working

Any help please?
Thanks

Please describe exactly how you wired this, as I don not understand what you have done.

I ran a wire from brake switch pinout from the ecu to a switch and then another wire and earthed the switch. So I have a 2 wire switch, 1 from ecu and the other to ground

Thanks

You need to be much more specific.

sounds like he's got 2 switches ran to activate datalogging the way he described it. Thats about the best I can figure out.

I have just 1 toggle switch

And what pin on the harness do you have it connected to?

And which pin out diagram did you use, Honda, or hondata?

I checked on the Hondata website and checked which pinout to use.
I found on site the pinouts that are for obd2 cause mine is obd2

Well this leaves one of two scenarios.
1:You haven't set up smanager properly and uploaded
2:you have the wire to the wrong pinout

I have 3 questions to ask:
#1- I just want to make it clear and see how exactly you wire the 2 wire toggle switch?..
l see that you can choose one of the following switch output from the ecu. a/c switch, brake switch, power steering, vtec, and service connector. So let's say I want to choose b8 "power steering pressure" to datalog manually. So i cut the wire connecting to the b8, use the existing wire from the ecu side, then connect that wire from b8 to one wire of the toggle switch and here's the simple question, where should we connect the other wire from the toggle switch to? is it to a chassis ground? or 12v switch at the fuse box?
#2 What would happen when I cut the wire that was connected to my power steering? I still use power steering and A/C on my car.
#3 I also want to install another switch "toggle" to have a secondary map. I want to use 93 octane on one map then E85 on the other. Is it the same way as my questions above? I hope I explain this as simple as possible and I appreciate the help anyone can give.

The other wire, I put it to ground , but still nothing

Any help on these are appreciated.
