Anyone out there who konws if the 380 have a knock sensor?? i was wondering if it would actually benefit from V power...

Yes and yes.

Sorry to thread mine a bit, but I didn't want to start a new thread and get abused for starting a new thread with info that has been covered.

With the 380 having a knock sensor fitted, would it be beneficial for me to reset the ECU (ie: unhook, wait and reconnect the battery) after filling it with 98RON and let it adjust to running high octane from scratch? Or would it make no difference and have roughly the same benefit after driving for a few k's with the higher octane fuel?

no need to do an ecu reset

the knock sensor will pretty much intantly detect that it can advance the timing without pinging.

just sit back and enjoy the added power and economy from it.

probebly been covered but can u add a knock sensor to a 3rd gen?

Nooooooooooooooooooooooooooooooooo :rant:

Probably easier to just run a Piggyback

and a hell of a lot cheaper. SOHC 6G74 is designed to operate without any form of octane monitoring device. It could never be done

In my experience because the ecu is only tuned for standard 91 octane there is negligible if any effect on power or economy. However once a piggyback is added & the maps fine tuned along with extra timing advance there is a substantial improvement. All the exhaust & intake mods should be done also to get the full benifit.

Yeah, exhaust is on the shopping list down the track a bit. Intake is on order from USA.

Am yet to look into ECU options for the 380, but will probably open a discussion on that closer to the time when I'll be doing it because things may change by then (ie: different options available and/or more people who have fitted units and have experience)

Since the 380 has one, I guess the only way you could do this is to do a 6G75 conversion (the 380 engine). It should bolt right in as the engine is basically a boared out 6G74 from what I heard.

You would also then be benefitted with an extra power gain.

Best bet if you were to do this would be look around the wreakers for a 03+ pajero.

i know my one doesnt work cause its been pinging since day 1. i've had shell and caltex fuel cards and used optimax and vortex nothing will stop it pinging. :(

If you have a 6G74 3rd gen engine, you wont have one at all

certainly hope not cause i got the car new :redface:

pretty sure you would have a hell of a job dropping in a 75 if its fly-by-wire throttle. not sure tho?

Not hard to fit a mechanical throttle. Depends how other throttle dependant components are run. TPS etc
