Re: Fake flex fuel sensor

When the fitting of after-market flex fuel sensors was unheard of, the first few suppliers bought the Continental sensor, ground numbers off, then stuck a label over it to pass it off as their own. These days, the parts are well known, but someone somewhere obviously still thinks they are still to b...

Re: Inputs over canbus? Cockpit expander

Marketing issue I imagine! S6 was an entry-level product, compared to the Life Racing F88 options available at the time. Syvecs/Life Racing have not implemented the generic receive capability on the S6 (which is obsolete now anyway) - since it can run a full blown I/O expander it won't be a hardware...

Re: Inputs over canbus? Cockpit expander

You're still on an S6? So no ability to receive input data via CAN except using the slave protocol, which nothing other than Syvecs/Life Racing-specific IO expander units support.

But the module looks to be fairly good value for sure!

To receive data using "normal" CANbus you will need S7plus or S8.

Re: Wiring led from ecu output - constantly dim

Oh, yes,sorry. So a pull-up to battery should do the job. Value needs to ensure the shiftlight connection remains just above battery volts minus the forward voltage of the led(s), with the leakage current flowing, and wattage chosen to ensure it is OK with full battery volts across it.

Re: Wiring led from ecu output - constantly dim

Actually, a pull-up resistor might do it. Without knowing the leakage current we're dealing with, nor the characteristics of the shift light input, its difficult to be sure, but if it was, say, 10mA, then a 220R 1W resistor from the output to battery volts would allow the shift light input to sit ne...

Re: Wiring led from ecu output - constantly dim

You could no doubt find a suitable mosfet, which would need some kind of pullup resistor on the gate. I would still be tempted to use a through-hole solid state relay (which would still need a series resistor to limit the current flowing through the trigger LED) - they're just a few £'s - simply bec...

Re: Wiring led from ecu output - constantly dim

The leakage current of these ECUs does seem quite high - can't be used for a DCCD drive, for example, as the leakage means the DCCD never goes fully open. A typical injector driver device only has a leakage current of 100uA or thereabouts, so the output stage in these ECUs must be a little unusual. ...

Re: Streamed data SData

Not ever used streaming, but I see the folder you've "pointed" to is related to Google drive. I wonder if the "device" is not the ecu but the folder for the streamed data and there's an issue because Google drive has some kind of control over it for syncing purposes?

Just a thought.

Re: Mounting GPS module

Must be level and, ideally, central in the car - so in the vicinity of the gearlever/handbrake is right. The orientation is mandated by the manual - which unhelpfully is nicely vague as directions are described as "x" and "y". I believe it has to be mounted with the connector mounted pointed forward...

Re: Problems connecting Expander.

OK, not played around with KT8 on an S8 but receiving data via generic receive makes perfect sense. But S6 simply does not support generic receive. S7+ does, but not S7I. So S6 *used* to allow KT8 to be received via slave link but I wonder if Syves have deprecated that now the S6 is obsolete and the...
