I am working through calibrating timing and seems like the ECU is not sending any spark signal while cranking. I must have configured something to disable ignition but am not sure what it is. Here is my current tune file and a log during cranking. 11_6_22.pclx PC Datalog - 2022-11-6 3;56;17 pm.llgx

G4X (NS15X) was connecting fine to my PC, and now seems to have stopped being recognized by the PC. Stays in a consistent "Searching" state. When I plug in the USB to the PC I hear the little windows jingle that indicates something was plugged in. It makes this jingle whether the main power switch is on or off. I've tried both restarting the PC and power cycling the vehicle power by disconnecting/reconnecting battery. Attached picture include more version information. You can see in the device manager that the computer recognizes the Link USB when it is connected. EDIT: Fixed itself the next day. No idea what caused it.

Thanks, these are exactly the units I was looking at. May see if I can get a unit directly from TireMagic on Alibaba who I think is the OEM, so we'll see! Does your team have any direct experience with their units?

Doing some digging to see what options there might be for a TPMS system. I'm setting up a realdash display I'm hoping to output the information on. I've found some aftermarket receivers which are coupled with a display; Are there any oem receivers that I could potentially retrofit into the canbus or any aftermarket options designed for this?

I have been playing with sending data to a realdash display using custom user streams. With "Batt Voltage" for example, the value that is sent through rounds to the nearest whole number (ie. 11v, 12v, etc). Can I increase the fidelity of this value to two decimal points? When using a digital dash gauge within the Link software I see a value with two decimals. TIA! EDIT: I see that this exact use case is documented in the help files for the Test Calculator tab. The file is named "User Can Setup" if anyone stumbles on this thread in the future.

I bought this sensor/gauge combo not realizing it was not the X-series. This device has both an analog 0-5v out and a RS232 out. Can I configure this to use the RS232 out? Will this result in a better reading than using an AnVolt? I currently have it connected to the RS232Rx port but am not sure where to take it from there.

Will do. Can you give me more insight into what the min/max clamp value does? I have read other suggestions to set the max open/close values to 98% so the motor is not struggling to keep the plate near the end of its maximum ranges. Would this correlate to 98% min/max clamp values? I also saw for example that the GM throttle body it is recommended to set the clamp to 90%. The bosch wiki doesn't have recommended values for this. Thanks so much for your help today -- Just a hobbyist mechanic so doing my best to keep up here!

Was able to get the calibration to succeed with that. Still quite a bit of noise coming from the throttle body when e-throttle is not in the disabled state. It sounds like a buzz or hum coming from the throttle body. The pitch of the hum changes with the PWM frequency, it is a much higher noise at 10k than it was at 100. Attached is the new calibration. Any suggestions to eliminate the hum? PC Datalog - 2022-09-18 9;26;25 pm.llgx

Yup! Here you go @Adamw 9.18.22 map.pclx

I'm new to this software so not sure if I logged it correctly. I set the values to the ones in the help article and ran a calibration. I get an error something like "Error 5: no main movement" when trying to use those PID settings. I took two logs each contains a unique calibration with the same result.

Thanks! I was able to run the TPS calibration now and have it succeed. I did need to reverse the active state on Aux 9 from Low to High. I left the default values for these: - PWM Frequency - Proportional Gain - Integral Gain - Derivative Gain When I attempted to use the suggested values in the help article and calibrate, I got an error that the throttle plate did not move. However I hear an audible hum coming from the throttle body when it is on that makes me think these values need to be adjusted. This is the specific throttle body I have installed: https://www.summitracing.com/parts/BCH-0280750151#overview. Do you have any suggestions? in -

@Adamw What value do I set for "E-throttle relay 1" in this case? When attempting to run the TPS calibration I get "Error 1: E-throttle relay NOT selected."

I had my NS15X ECU sent to your main office in NZ to have the e-throttle added. My understanding is that this means I do not need the external e-throttle relay you're mentioning here? The ECU I received had the 4 cables Aux9,10 and AnVolt7,12 coming out of the ecu board with a small bit of clear glue on the circuit board where the wires are attached.

Thanks @Adamw! I think the answer is yes but just want to confirm here as well -- Is the aux out enough to power the ETB without a relay?

Specific TPS/APS Applications > Bosch Bosch Bosch PN 0 280 750 473 Electronic Throttle Body (82mm bore) & Bosch PN 0 280 750 150 Electronic Throttle Body I am looking at this help article and want to verify that I am wiring this to the ECU correctly. Based on this pinout would these values be correct? Electronic Throttle Body Pin 1 - Aux 9 Pin 2 - ECU Gnd Output Pin 3 - ECU 5v Output Pin 4 - Aux 10 Pin 5 - ANVolt7 Pin 6 - AnVolt12 Additionally I also have my gas pedal wired up to: APS (Main) - ANVolt8 APS (Sub) - ANVolt9 Are these wiring values correct? Thanks!
