I have one too!

I think we had better stop telling Tony we have got them before he goes round removing them all with his grinder

Flipping cheek! no mention of sorting your trucks diff till past 21:00! or why we (thats WE, not I!!) were playing with the grinder.

I dunno, no bleeding respect or thanks in this place,.... mutter, mumble, whine, moan, complain, etc, etc.........

Fingers crossed so far so good, I now have one ground down ring spanner to fit rear diff pinion nut its for hire
respect there you are

Wooowwww, we're not worthy!

The item in question is a Pulse Sensor. It picks up the movement of the exhaust gas flow. Eg: 2000 x 4 = 2000 Rpm. 4 pulses to the revoloution in the case of the four cylinder models. In the square rubber are two carbon poles with a mica disc between them that sends the frequence reading to the Ecu. It's to assist the fule timing. The Aussie's have a mod to fool this piece of equipment so that it pushes more fuel into the injection system giving a better performance. Some say it did not work. Mabe thats why its not present on all our Surfs. ???????

Hope this clears up the mystery.

if thats the case a: why is there no wireing to the part and b: does that mean i need to put it back?????

[da SLUG man]

Yeah thats Fred - sadly Sunday morning he died at the ripe old age of 28...

you've been talking to my mates girlfriend again!... he's only 27!

Is it driving any differently???

[Lickit]

will let you know after the pit this weekend, tell tony thanks again for the work it looks realy cool now, and think it will save me a fair bit of trouble

Always a pleasure to welcome new visitors to the Linda & Tony garage... LOL

Good theory, but why is fitted on non-EFI Surfs like our Grey one, Koi's and Jim's.

Just counting the pulses won't help it run better, a O2 sensor does as it reads the exhaust gasses and adjusts the mixture to suit.. All this is good for is a Rev counter as far as I can see.

I can see how this would work , but I think it would need to pass through a 3mm carbon filter to help . If not , a blocking diode going round the speedo cable and then back up to the aeriel might help , or am I the only one thinking this ?

I Think I've just entered the twighlight zone

Probably!

Still begs the question... why bother counting the exhaust pulses, any miss fire or rough running, which most motors do when reving high, would leave you messed up.

Fueling measurements need to be measuring emissions compared to throttle position and intake pressure. And it can't measure emissions though a exhuast pipe, and inside the crossmember.

(PS whats the carbon filter for? or you talking about the O2 sensor)

No Andy, not the twightlight zone . TWIGLET zone , yum yum .

It dose not measure Emissions it measures PULSES. As for the backfire's I would suspect that the ECU would take care of that in it's usual way and put the turbo into safe mode.

No there are no wires on this as the Mica disc oscillates between the two pieces of carbon setting up electronic frequences a bit like the old crystal set.

No S**t we still all on the same planet, its like the ssr, ssrx, ssg badges they has some bits left over and stuck em where they could.
