Re: Flex fuel sensor
Set the input type to Bipolar. Only the AU types need to be set to thermistor. Found that out myself a few years ago even though it's counter-intuitive when the sensor "needs" a pullup enabled so you'd think thermistor for sure.

Re: audi coils
I've wired these in for people a few times for various ECUs.
Apart from +12V and the trigger, there are two grounds. One is supposed to be taken back to ground pins at the ECU and the other taken to the engine block. They worked for me wired like that, anyway!

Re: Pin does not support the required input config
It may not like VVT on X10 inputs either as it can't reliably get the data, via CAN, to sync up correctly.
If its an F88R it only has 8 frequency-capable inputs and I suspect AN16 isn't one of them!

Re: will S7Plus work with Bosch Motorsport ABS M5 Kit 1?
SCal says yes. Look under Datastreams, and then "Bosch ABS M4 CAN Receive" and there's "M5 Mode Enable".

Re: GDI4 ECU current supply
Yep - agreed - Syvecs rewrite of the actual spec is ambiguous. DBW is good to go

Re: GDI4 ECU current supply
yes, but the GDi4 spec does not mention it having full-bridge capability. It's probably just not written very well. But I still commend checking with Syvecs as these little things are there to bite!

Re: GDI4 ECU current supply
There is no GDi4 section and, as I understand it, the GDi4 is a variant S8 anyway. As said by Stevie, do not drive constant current devices such as pumps direct. Nor PWM high current devices (such as pumps). And I can't see a way in SCal of assigning a pair of half bridges to a DBW motor. But maybe ...

Re: GDI4 ECU current supply
PWM using low-side drivers is still the ECU sinking current - no different to an injector drive. However, it is generally not a good idea to drive fuel pumps or water pumps direct from the ECU - they just take too much current. If you want to PWM these, use external solid state relays. DBW motor is ...
