Re: Cold "cold start"

Setting "High Trigger Threshold In Cranking" to 0.6 did not work. The car would "start" and then stay at cranking rpm.

I changed "High Trigger Threshold In Cranking" to 0.9 and it seems OK. Today started successfully at -18C.

Cold "cold start"

To my surprise this morning my car refused to start. The engine is 2004 USDM EJ257 with drive by cable throttle body from EJ207 running Syvecs S6PNP. Outside temperature was -16 C or a little bit less. The engine cranked OK - a little bit slower, but perfectly normal. However, the engine did NOT eve...

Yes, that's what I'm trying to do.

Re: Sharing inputs

Thanks!

One more question - Is it somehow possible to use the input from two pins to decide whether to activate a function?
e.g. If (clutch==DEPRESSED && brake==DEPRESSED) Blip();

That can be achieved by adding some hardware (an AND Gate) but a software solution would be nicer.

Sharing inputs

Is it possible to use single input pin for several tasks? (e.g. Clutch Depressed Switch / Gear Blip Request / Gear Cut Request)

I tried unsuccessfully to use pin AN15 for both Gear Blip and Cut.

Thanks!

Re: Water / oil / fuel temp sensors

Rterm - thermistor resistance
Rbias - bias resistor resistance

AFAIK bias resistor value for Syvecs is not published.

Take a look here:

Z1 - bias resistor
Z2 - thermistor

Re: Water / oil / fuel temp sensors

As far as I remember this is what you are looking for:

Code: Select all

Vout = Vin * Rterm / (Rbias + Rterm)

Re: Subaru IAC valve

Thanks Pat!

It turns out that my IACV is damaged - the shaft is bent slightly and a piece of the magnet is missing. However, with a little bit of luck and your thorough instructions I got it working until I buy a replacement. 1 kHz and Active Low worked like a charm.
