Karbonius Race Airbox
- Thread starter GT Spec
- Start date
Finally done it - placed the order yesterday, circa 8 week lead time!
Any recommendations for the Alpha N remap - I am based in the Midlands?
I am assuming it will be ok to drive to the mappers after the intake is fitted as it will default to a 'stock' map in the absence of the MAF data?

Just installed the karbonius race this evening but have 2 questions if anyone can help...
1. This circular valve which normally clipped on to the side of the original airbox, how have you secured it, I can see there's a mount on the airbox but it would sit vertical not horizontal?
2. No picture, below the airbox, above the dipsick, there's another valve which is rubber mounted and slides on to a tab under the original airbox, again, I can see there's a tab on the karbonius but it's 90degress out, so rather than sitting parallel to the engine it would sit square to it. How have you mounted that one also?
In the mean time I've cable tied while I get mapped but I'm not happy with a cable tie solution and maybe I'm being a bit thick!
Thanks!

Some further updates on this, replying here just so the useful info is on the forum for anyone in the future.
Lesson number 1, IATs are not created equal, I had an FAE CSL scaled one and swapped for a Hella with the same scaling. On a cold day the difference between them was nearly 5%. Car runs better with the Hella edit to add, car runs roughly 10degs above ambient at normal road speeds.
Lesson number 2, coil packs and plugs, might not be giving any spurious CELs or running issues but they can cause a problem. 2 of the coils had quite different resistance readings to the other 4 once I removed them and got them on the meter. Plugs looked OK but no point doing half a job. Full new set in, again, car much better at high rpm.
3. Not confirmed yet, but from logging fuel trims and lambda voltages, I think one of the lambdas is on its way out. New ones here, mission to fit with the exhaust on the car so will tackle that once the weather warms up and report back.
Hopefully helps any future people out 8)
