<- real tears
Maybe they should have a tank of each fuel and then they could have mappable fuel pump control to mix it "live" to the correct mixture to avoid problems
That of course all totally ignores the fact that you are trying to solve two totally seperate problems though, ie both the timing and the fuelling being wrong.
Not entirely sure why that was aimed at me (I'm not here to represent a particular car, website or a garage), but my car was mapped on pump super unleaded, that's all I put in it, that's all I am ever going to put in it. I don't want a road car that needs to use race fuel.
My point was that I could see some validity in people choosing to use a bit of extra det resistance as an extra safety margin. I wasn't opining on the effectiveness of doing so.
I'm not sure what it has to do with "skyline tuning" either. It's pretty pathetic that people want to be so divisive about it in any case - I'm interested in cars, full stop (which is why I'm looking on here). One of the cars I own at the moment, and like, happens to be a Skyline GT-R - the next one I buy most likely won't be.
I make my own mind up on the basis of my own judgment as to where and how it's built and looked after, and I know (unlike some) the limits of my knowledge and experience.
Re the compression issue - I have an opinion based upon what I have seen and read, but I don't pretend to know everything about it (again, unlike some). However, I am interested to look and learn, which is why I'm looking forward to seeing how Steve's car performs when (if
) it's finally running.
Maybe I should just buy an old Sierra and get with the real cutting-edge tuning gurus
