I am in the process of installing 555cc nismo injectors in my RB25det. I have figureed out the following from searching:

555/370 * 100 = 150%

Therefore should I set the injectors to run at 50% in the injector correction table???

& What do i do about the injector lag time :D ?

Another thing worth noting is that I am also going to install a Z32 AFM. I know about setting the PFC for this, but others have mentioned that the Z32 may lean out my mixtures, is this the case?

it's the other way around mate. work out the percentage you old injectors were relative to your new ones. in this case 67%. i don't even think the injector correction goes over 100%...

as for lag time, can you use google? if not stop messing around with your ecu if you can, then use it, find the lag time, key it in to the PFC. done. now you will need to take it some where and get it tuned properly anyway.

if you really must drive there and are tight on funds i'd suggest install the injectors by all means, wire up the AFM plug too, but drive there with the old AFM plugged in. when you get there stop out the front, plug in the new afm, bolt it up and in you go. simple.

or you could just shell out and get it tuned ... I have 550cc injectors and a z32 AFM, no problems from here, cos I got it tuned ...

I am only asking as I need to be able to DRIVE to the tuners place. Offcourse I am planning to get it tuned, why else would I get bigger injectors????

      How old is too old for tyres?

      By The Bogan · Posted

      Also, a tip for young players  Check the dates on new tyres before they fit them, I always ask this question at the tyre shop, as they have tried to put "new" tyres on one of my cars a few years ago, but the build date was about 3 years old

      Yeah - 4 or 5 years is the limit for decent tyres. Pedestrian grade tyres with 400 TW ratings start out hard and don't start to suffer until they are somewhat older again. But the stickier decent stuff? Nup. My current ADO9s are < 2 yrs old, 17000km in, only have about the minimum 2mm of tread depth left, and they are.....not what they used to be. They are clearly much harder now than when new. Whether that is heat cycles (unlikely, for a road tyre), different compound between top and bottom of tread, or actually aging out (in less than 2 years!!!) is not really able to be discerned. But I'd credit actual aging as being at least part of the cause. I've got an old pair of ~50% worn AD08Rs in the shed that I really need to get rid of. They started feeling waaaay too hard to put back on the car after a couple of years sitting there.

      Personally I wouldn't put tyres over 4 or 5 years old on any of my own cars. Once they go hard the grip characteristics completely change. As per most things it only matters in an accident and that's when you most want them to do their job!

      I'm replacing the front tyres on the E39 tomorrow because one of them has a few gouges out of it. There is so much tread still on them but they're also 9 years old and the rubber is super hard.  This falls within the guidelines of 10 years old that I've read which surprises me given their condition.  I'm curious about whether you guys care about tyre age or just judge the tyre based on condition? How old would you consider too old?

      What starts as a scratch, becomes a flesh wound, then quadruple amputation. Jus' sayin'. Crush resistant gloves (The ones with the rubber strips down the back of the hand and fingers) might not be a bad idea after all!
