I bought the k-Tuner user board about a year ago (installed in manual Accord ECU at that time) & finally got to the point where the car is ready to start. K24a3 in a Bertone X1/9.

I have no grounding of the main or coil relays via E7 when key on or cranking. It was suggested the immobilizer could be the problem.

I thought that was disabled when the K-tuner chip was installed in the ECU. Can't seem to find specifics on this, but maybe I just don't know where to look.

Any advice would be appreciated before I have to rip the wiring apart to fault trace

See the disables section.

I looked here:

..nothing about disabling Immobilizer. My tablet just died, so I can't go in to the software, is that where you mean?

To answer my question, it is not disabled unless the end user (me) does so?

EDIT: found some screenshots from back when I set the ECU up:



So, it looks like I did set it to disable. That's bad news, since the ECU is acting like it's disabled/locked : no switched power to E9 via C201:12, or coil relay output (C201:13)

If it's disabled then that is not your issue. Sounds like it's time to hunt through your wiring. I'd check to see that the ECU gets power by checking for LEDs with key on.

Thank you.

To wrap this up, I had mis-wired the E9 feed from the main relay output, instead of from the fuel pump feed fused (15) circuit. Not sure how I misread the diagram, but that it is. Thankfully, that's the only wire of at least a hundred connections I mis-placed



added an extra wire from my fused pump feed circuit - using bk-y -to go to E9







Started right up after that. Still have to look at the TPS calibration, I read somewhere one does that in the software, the idle surged after initial high idle mode

Glad you're making progress!

There is a button to set the zero point for TPS in that section of settings. This will only work if you're in voltage range where the ECU is happy.

Thanks for the tip, I'll look for that.

No problem

I clicked the button, but didn't get any popup notice or anything, Just the button turned red, so I'm assuming it's out of range. I'll have to check that the cable isn't holding it open. I set the butterfly to be open about 1/4 turn off the stop.

There's no popup. You'll see the TPS value in logging change.
