Syvecs Forums

Thanks Paul - all makes sense, and will make sure I do things the "usual" way from now

But you can choose which edge the Syvecs triggers on so shouldn't matter really?

Related to this...the 2-pin AVCS cam sensors are VR types I believe? Does it matter which pin gets grounded back at the ecu? I'm assuming not since it is simply a pickup coil output?

And if it does matter (why?) which pin is the signal?

No worries - and realise my answer seemed a bit abrupt, sorry! Anyway, MAF connector has 5 pins, numbered 1 through 5, left to right, when you look at it with the "bump" on top (think that's the right way round!!) 1 - +12V (Yellow/Blue) 2 - Control Ground (Black / Green) 3 - MAF Signal (Gr...

IAT would need a ground on one pin not a +5V feed.

FYI have also added 3 bar MAP sensors and Bosch knock sensors to the website

Thanks Pat - I sometimes have a tendency to over-analyse and over-complicate things in my mind

Pat,

No, I know they're there for flyback/snubbing, so they won't be dissipating anything of note while the PWM output is being driven - as you know it is when the PWM output turns off that we need to clamp the back EMF: which is more complex to calculate than steady state dissipation.

Cheers,

Tim.

Thanks Jasper

What sort of power dissipation is there in the flyback diodes? Wondering whether they can simply be soldered inline with the +12V wire, with heatshrink over them, or if that's going to be a problem?
