i always read that on power fc's that you read the knock of the engine...now do i need to buy an extra sensor to be able to see the knock reading or is it standardly(if thats a word) built into the engine r34gtt neo.

so just plug in the power fc and it reads the knock right away.

or

do i need an extra (item)(upgrade) to be able to see the knock reading???

The knock sensors were put there by nissan, you just never had anything displaying what they say before

not in the slightest bit accurate.

if its a high number, you can almost sasume your knocking, but not necessarily.

if its low however you can probably assume you arent

lol @ not the slightest bit accurate

What a load of crap. If the sensor is dead or faulty... fair enough, but... then its not working correctly now is it?

Knock between 20-35 is acceptable for a good tune from a PFC.

40-100 your tune really needs attention... over 100 its just plain crap :P

Sometimes if you hit the limiter it will smash over 100 etc. As the knock sensors do at times pickup other noises as "knock" but this is not common.

I'm really interested in the use of the standard knock sensor. I have an SITC and a SAFC and want to tune my own engine. I got an LM2 to do the afrs but have been looking for a knock detection device. Guilt Toy suggests that you need a K-Mon device at about $1200 to do the job but are you suggesting that if i can get something to read from the standard knock sensors that i can use that reading to adjust timing across the rev range?

Adriano, any idea on the ecu address for monitoring knock readings? In particular a 32gtst ecu.. I'm running remapped stock ecu and have a carpc with Datascan running all the time so would be nice to get a knock readout :)

    • That's not a transistor --- it's marked ZD1 which makes it a zener diode. As to what the breakdown voltage is, not enough there to divine.
    • Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers
    • The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.
    • It's almost certainly the same as the one next to it.

    • South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
