Just a quick one....

I have replaced the exhaust, cat, intercooler and pods on my 33 GTR. the Power FC has recoreded some higher then normal knock readings also

Should i get a tune asap? or would it be ok to drive for awhile? As i cant get in for a bit to the tuner i want?

I'd be surprised if those mods were causing higher knock, unless your previous tune was pretty close to the edge. But it's definitely better to be safe than sorry, if it were my car I would assume it is knocking and not drive it hard until you can get a tune. You can still drive it, just don't go loading it up everywhere.

You would think a free'r flowing exhaust and front mount would reduce knock??

If you can't get a tune for a while drive it normally ie without thrashing it until you can get it checked

Out of curiosity what knock readings you getting now?

or just blanket some more fuel on the map, there's a chance with new pods the AFM is reading slightly different causing a lean miture, you don't have a wideband O2 by any chance?

AFMs are sensitive little shits.

Well you didn't need to swap the parts over, it was a choice. Just like it's your choice to go and get a tune sooner rather than later.

So keep babying it and say a little prayer each night.

^^^ haha.. :yes:

maybe this new exhaust system doesnt flow as good as the last and its causing restriction which =knock with the same timing etc.. :whistling:

      Yet another RB Neo misfiring thread after reading all the others.

      By GTSBoy · Posted

      Misfires when the car is fully warm are generally attributed to the coils (and/or the igniter, on cars with a separate igniter). They can stop working properly when they get hot for a number of reasons. Either electric/electronic, or from thermal expansion opening up gaps and allowing HV leakage. Seeing as you have replaced the coils, that could/should rule them out. But I wouldn't always assume so. Were the coils genuine? Or is there a chance you have bought some counterfeit Chinesium shit? Then we're back onto loom connections. They can fail when warm/hot for the same reasons. Inspections, cleaning of contact surfaces, ensuring that terminals are fully inserted, etc etc, are all justified. The same (heat effects) holds true for the other electrics and their connectors. AFM & CAS, primarily. If you try that Chinesium AFM, drive it around on low load until it is properly hot, but do'nt give it more load than you have to, except when you need to see if it will still miss. I'm dead serious about the untrustworthiness of the calibration of those copy AFMs. Injectors are unlikely to get hot unless the fuel is coming back around hot. You could try squirting them with compressed air or freeze spray to cool them back down to see if they are maybe the cause.

      Alright, all the plugs looks good. Noticed that it starts to get bad when the car is up to temp, that's when things starts to misfire hard. next to do is Injector cleaning and such. Got in touch with a shop to do work on the injectors next Monday also help on diagnosis.

      Hence why I've only modified my car into a pure daily. Everything has to remain reliable & roadworthy, while providing value and grin factor. It also must not be handcrafted to the extent that the car will be immovable if something breaks because you cannot get or make a replacement to at least limp around with.

      Nah, I definitely do that kind of stuff with my car. I do drive it around as a daily! It's just that mindset about building a car to actually still use/retain it's function as a car is rare. If you modify your car into a weekender, IMO you've ruined 5/7ths of the fun. It should remain fun to do daily errands in.
