tunning

[51OOO]

guys when u get the car tuned for more power what exactly do they do? and what are the gains an cost?

cheers

Change fuel mixture and ignition timing basically. There are other subtle things you can do depending on your ECU like temperature compensation etc but the main ones are fuel and timing.

On your R32 they would reprogram the whole ECU for around $600, and you'd probably gain around 10-20rwkw.

so to get it tuned and get the air feul ect it wound be around 600?

how long roughly does it take to tune a aftermarket or piggy back computer?

[JimX]

An hour or so if just doing mixtures. More if also doing timing. Probably more than twice as long, I'm not sure.

just have to remember that its not always about peak power figure, its the AREA under the graph that counts.

peak figure is always going to be restricted by the hardware you are running, so the difference between a good tune and an ordinary tune might not necessarily be in the peak figure you make...

If you just put a new zorst in and the rest is stock, should you, can you, tune it?

Mine is an r34.

Mine is an r34.

with a stock ecu? no.
