Do you have a log showing the sensor output?

I presume you are using a thermistor input, 1v low threshold, 4v high thresholds, 1 tooth per reading and the scaling will depend on the number of blades on the wheel being read per revolution, and the number of pulses the sensor spits out.

It's defaulting the sensor due to not seeing a high enough temp on the EGT quickly enough after starting. Look in the sensor menu for EGT and lower the threshold temp and/or increase the time period it will wait before checking.

no it doesn't that's a seperate issue! But you should swap the polarity, then disable the VVT (raise enable rpm) then re-measure the vvtRaw values (add then to a log temporarily or just add gauges at 1-2hz so they spit out the values) and then redo you latch offsets.

If you're really keen you can ...

Your AVCS sensors are wired with reversed polarity, that is the issue.

So first of all you can add vvt parameters to your logging config. Log the vvt abgle for left and right, log the errors and the duty and 10hz will be plenty.

All you need is one quick log of the vvt sensors from startup, then remove the vvt voltages from the logging, do you have any screenshots of ...

I would just tap into one front wheel speed sensor and try both the launch hold timer and the front wheel speed as inputs for Launch RPM limit.

Yes you can control the 4wd directly from the syvecs. Use the Attessa to control the pump and maintain the pressure. Use the syvecs to control the PWM ...

Launch control will usually run out to the end of 1st gear.

2nd gear onwards will definitely be TC related but for TC to work you need a rear wheel sensor (or two) to measure the drive wheel speed and while you can compare that against GPS speed from the Syvecs GPS box it't not fast enough from a ...

Your ignition timing is swinging due to idle control.

You probably do have a ground issue though. Make sure all the main grounds on the SYvecs end up on the many wires that go to the ground eyelet on the inlet manifold on the factory engine loom.

If it's only launch then TC is not the best way to do it, that's not what it's designed for. If you always want the perfect launch then you will always have some messing about to do. TC typically is used after launch control has been exited.

You're simplest route is tap into 1 wheel speed sensor on ...

I think you have 2-3 problems

I believe partly the problem is caused by running 2x bosch 044 pumps at idle where you are trying to set the fuel pressure at 4 bar. At idle there is not enough flow in one FPR to regulate the pressure when 2x044 pumps are running. This means that you set your pressure ...
