Probably not the best area, but ah well.

Depends on the type of BOV mate. Standard (factory) blow off valves are generally plumback, which as a rule generally means less noise pollution. It's when you start putting aftermarket Atmospheric blow off valves on your car when things start to go bad. Atmo BOVs i know are illegal in most states.

Best bet is a hybrid imo :thumbsup:

you got a permit for your atmo bov?! I thought it was emissions reasons you couldn't vent to atmosphere.. not noise.. if it's noise then I can argue the case for the huge sard thing on my car (came

with a permit for aftermarker plumback bov, not atmo) but it's so loud I'm putting a standard one on.. still got your plumback plumbing?:pirate:

Yeaqh, at the time it was a Greddy S Type. Went over the pits to get rid of a yellow at east perth, and the guy said I needed a permit for it...and the strut brace...and the pod filter...and the aftermarket seats :)

Sorry, dont have the plumbing...had the Type S on it from Japan

    • I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though 
    • $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.
    • Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.
    • I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.
    • I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
