Nissan Skyline R34 GTT

Post by steve_s13 » Fri Jan 08, 2010 8:53 am

Well thought id get posting some results up (seeing as im always normally just emailing em to Matt)

Car in question was a nice factory R34 GTT (just usual breathing mods, fuel pump and pod filter)

Kinda typical as to what id expect from a NEO engine, made a little more than your average considering boost was limited ;) (see graphs on link)

Was a very cold evening but spend most of the time steady state tuning and focusing on ignition

Thought you'd maybe wanna see these ones Matt & Pete

I was more than happy with the results and the engine performed much better on the road (before and after graphs also shown on the link)

ps
ill have another couple more R34 results to upload shortly, as well as some R32 results

Happy New Year all

hey steve , maybe u can help me out, we are treying to tune the car 2000 skyline neo engine, we went with a topmount and bigger turbo, changed the maf, stgock injector.

my problem right now is that it's overfloding the cylinders,

right now i changed it back to stock maf.

what is your k constant? or injection multi?

i think for some reason mine is to high.

are you using a Dyno to tune the engine and set the boost, followed by checking on the road?

are you using a wideband to check the fuelling and using Knock sensors or Det cans to check and adjust timing?
