I'm scratching my head at some new behavior I've hit. Hopefully more experienced eyes will see something! When I activate the Aux output for my fuel pump relay (Aux 1), a bunch of the other Aux outputs go to the Fault state. When I deactivate the Aux 1, the other Aux outputs go back to Active or Inactive as expected. I can activate other Aux outputs normally. The fuel pump doesn't turn on when I activate the Aux 1 output. I can hear the fuel pump relay actuate, though. The Aux 1 output is hooked up to the low side of the fuel pump relay. Documentation says that Fault state on Aux output "indicates the hardware is not happy"...which I'm not quite sure what to make of. Any clue about what kind of problem I should be looking for?

It can work! Look at the post by Boost at the end of this thread.

I've been setting my XtremeX and Razor PDM up similarly to what's described at the top of the thread. I first tried using Aux3 to provide power to the PDM's Ignition Switch input. That didn't turn the PDM on. When I measured the voltage of the connection it was about 2.5V. I tried using Injector8 next and got the same result. When I moved to Aux7 the PDM turned on as expected. However much current the Razor draws from its ignition input, it appears to be more than the normal ECU outputs can provide. You need to use one of the higher current ECU outputs -- Aux 5-10, I think? -- to turn on the Razor PDM. Does that sound sane, or am I doing something wrong?

You almost nailed it! Turns out the wiring was good -- trigger 2 was correctly on the exhaust cam sensor. The problem was that the trigger wheels were physically on the wrong cams. Swapped the trigger wheels between the cams and now it starts like a champ.

Great, thanks for confirming! I still think there's something wonky in the Trigger Mode selections. The following steps will demonstrate: Open this new base map, and go to the Trigger Setup tab. Trigger Mode is set to Honda K20 VTC, and Trig 1 Edge is set to Rising. Set Trigger Mode to just about anything else that forces changes to trigger settings. I picked Porsche 944 for no particular reason. Set Trigger Mode back to Honda K20 VTC. This time Trig 1 Edge is set to Falling. Previously it was Rising for the same Trigger Mode setting. I'm not blocked by this or anything! Just wanted to make sure you knew about the behavior. I'm trying this in PCLink version 7.1.21

I'm trying to track down some intermittent starting problems -- hopefully some expert eyes can spot the problem! Engine is a Honda K24. About half the time, the engine fires up and idles smoothly within a few cranks. The other half of the time the engine turns over but doesn't start, often with a nice loud backfire. The backfire makes me think trigger sync problems but so far I haven't found anything interesting the logs. I've captured a log with a some successful and failed startups. I've also got scope captures of both successful and failed starts.

Just wanted to chime in that these drivers are working for me using UTM on my M1 Macbook Pro. Thanks for posting these! Turning off Driver Signature Enforcement was the only stumbling block that I hit. Worth noting that this requires a Windows reboot -- instructions here (Option 1 in the article): https://www.thewindowsclub.com/disable-driver-signature-enforcement-windows

Just noticed a potential error in the Trigger settings for the Integra Type R (DC5) sample map. When I open the file fresh, it's got Trigger Mode set to Honda K20 VTC. Trig 1 Edge is set to Rising, and Trig 2 Edge to Falling. If I change Trigger Mode to Honda K24 VTC, the Trig 1 Edge changes to Falling. If I change Trigger Mode back to Honda K20 VTC, the Trig 1 Edge stays set to Falling. Trig 2 Edge stays at Falling in all cases. I think Falling is the correct setting for Trig 1 Edge for both K20 and K24. It looks to me like the base map has Trig 1 Edge incorrectly set, but the settings in the Trigger Mode options are correct, and changing the Trigger Mode will set Trig 1 Edge correctly. Can anybody sanity check me on this?

From what I read in the PCLink help system, it looks like the Speed Limit function uses fuel and/or spark cut in order to control speed. My intended use is to have the driver push button that activates the a 25MPH limit. I have a couple of questions here: 1) I fear this will end up being jerky -- have folks had success with a smooth vehicle speed with the fuel/spark cut? 2) If I'm using an electronic throttle, is it possible to control pit speed that way? I thought it might need to go through the Cruise Control functions to do this, but on browsing I didn't see a way to set up a pre-defined limit.
