Does your rb gearbox have the common input shaft bearing sound? (One one where it goes away when u push the clutch in or get to higher revs) I heard if you put the wrong oil it can get this sound. -
There's more than one way to skin that cat, and most of the sump Maatouks have done will be GTR sumps. They are HUGE in GTR drag racing here. -
Yeah...I always start at the shift solenoids, because there's only a few reasons these will spook into limp mode, and bad shift solenoids is one ~ the other can be the shift control module (if you have steering wheel shift buttons)...it's easier to eliminate the solenoids first. -

Might piggy back off this thread since there's been a good discussion about PWM. I purchased a Walbro 460 F90000267 and have been looking into PWM to understand it. It was purchased more of a future proof as my original OEM fuel pump died (r33 below 200kw) and figured I'd just upgrade it to this. That's when it hit me that a pump this big can cause more dramas with such high amperage draw and heating of the fuel pump being on 100% all the time in such a mild setup. I have a Nexus R3 and slowly collecting power mods but I was looking into the PWM feature on the NSP software: Then looking at the graph from the fuel pump: Am I safe to assume reducing duty cycle to 50% for example would make the pump run like a 230/lph ? Where does the PWM come in all of this ? I've gone down the rabbit hole of PWM fuel pumps and it seems there are many differing opinions on how to go about it 😅 -
Thank you, this will keep me busy for a bit. I will update progression.
