yes, no problem, both devices default to 1Mbit/s , the CAN Lambda is not terminated but the ECU always is and the dash is configurable. I would probably put the CAN Lambda in the middle of the bus and use the ECU and dash to terminate (the dash termination is configurable in race studio if it is relatively modern)

It should work, I have done this with an extreme before on a customers car when i ran out of ID channels. You are limited to 10 streams overall though IIRC, so you still won't get 12.

Engine speed set too high?

As far as I know, master/slave ISCV control can only be on aux 1 and 2. You will probably need to move vvt to aux 2, 3 or 4
-
Digital input frequencies are based on edge triggered events, not analog sampling . The maximum guaranteed input frequency for the fury is 500hz. The actual maximum can be significantly higher if the processor isn't maxed out.

don't understand how to set it upWire the spare aux out directly to the spare digital input in a loop (I have used aux1 and di1)
Change your CAN input variable from steering ROC to a spare CAN TC Cyl input (temporary variable that can be acted on by a GP Output)
Setup the aux and di as below and change the switch condition to the ROC threshold you want to trigger the power steering idle up.

Works great
how can I now use the steering as a digital input that is taken into account at idle speed?
i need that for traction controlIf you have a spare aux out and a spare digital in you can connect them together and setup a condition based on steering ROC that triggers the DI for PS idle up.

Is it a Toyota 6 wire ISCV.? Have you supplied ignition switched live on the other 2 pins.?
-
Also, what ECU is the car running? If it is an Atom, Monsoon or Storm, it only has CLL trim, not Auto (which is able to provide faster, large corrections)

The G4+ PWM outputs cant do highside drive, only low side. The Aux outputs already have a 1.5Kohm pull-up internally.
Ah yes, Low side only, my mistake. The reason I would add the 10k pull up in the connector is in case the ECU or Aux got disconnected accidentally, the pump would come on full speed.
-
That isn't the pump manual, The 500mA current specified is the maximum output of the TinyCWA controller, not the current consumption of the PWM input pin on the pump (which will be much lower). You can control these pumps with either a high side aux, or if none available you could use a low side (I would add a 10k pull up resistor in the pump connector)
Also, worth noting these pumps should be installed as low as possible and work best in a "reverse flow" configuration as they cannot suck air, and so will fail to pump if coolant levels are low and mounted in the top hose

I think we will need to know what vehicle this is

The CAN output sends the Virtual Aux status bit. (it subtracts 1 as ON is represented by the number 2, as a side note I would have thought OFF=0, ON=1 and FAULT=2 would have been more logical)

We have experienced an identical issue recently (with a skyline plugin). It was resolved by updating the firmware on the ECU and the dash to the latest version and then using LINK - CAN_BUS_BASE_LCC (ver. 02.00.05) in racestudio.
HTH,

The find devices tab is only for links can lambda so no other devices will show up there. Try selecting transmit generic dash instead of transmit user stream 1. You might also need to run racestudio and configure the dash to read the stream, I think there might be an example on here if you search.
HTH,
Richard.

also, for reference I think the default CAN ID is 1636 decimal, 0x664 hex.
-
Just tested mine on the bench, getting pretty much fixed 40mV offset at all battery voltages, so negligible drop for me.
-
Here is one i put together. It was done a few months ago with a pre-production unit, so might need to check that nothing has changed.

One of our most popular kits is the Atom to run the 1uz cop, but usually normally aspirated. As mentioned above, the storm is a more capable ecu for that configuration, giving you sequential injection, sequential ignition, closed loop boost control and probably most importantly knock control.
-
choose EGT (0-5V) for the input, then choose a calibration table, probably table 4,5 or 6 as most thermocouple amplifiers will have a linear output, then enter the calibration values in that table.

ECU for 1ZZ
in G4+
For dual use road and track cars I tend to wire launch control into the handbrake (ground switched active) but I put a switch in series with it so it can be disabled and the handbrake used as standard. Into a DI with pull up on and set to active low. We have used the clutch pedal before too, but I find the handbrake to be more flexible with the deactivation timing.
HTH,

Yes, pc firewall. Also, try reducing the communication speed a bit in pc link, see if that makes a difference.
ECU Hold Power Wiring
in G4+

No, its fine with ignition switched live, once configured correctly, the ECU will initially power up through the diode on the DI. You can safely put 12 Volts to any DI, it will register the ignition switch off at about 1 Volt and start the hold power timer.
