e15et timing

[poeticjustice88]

hey all, just wondering if anyone could shed some light on this for me

n12 e15et with MT8 computer, A/R 80 garret turbo T25 i believe, front mount exhaust and BIG external fuel pump.

my dizzy has been adjusted and is all the way to the front.

to describe without photos, put your right hand on the dizzy with the bolt loosened, and turn right.

i believe this is advanced, im not sure as i have no timing light. but was wondering if all the way one way or the other was normal ???

thanks in advance

if its all the way then yeah it advanced all the way, it should be set at 15 deg BTC at idle with no load

Ahhh.. nope. Box stock yes, Aftermarket... nope!

To set the base (static) timing with a Microtech, you have to look up the IDLE and T deg.MAP ignition tables with a tuning handset and see exactly what the timing is specified in there.
Next, youll need to lock the timing at 10 degrees in then CONFIG. (s3) screen which is usually the default (STATIC in s1 screen) and adjust the dizzy to read 10 degrees on the pulley.
Next, unlock the timing with the handpiece and verify with a timing light that the timing you have specified in the ignition tables agrees with what is showing on the pulley with the timing light.

IF the figurres agree with each other then you need to specify more CAS offset which will bring the dizzy back into the middle of its adjustment.

UNless you have a handpiece, AND know what your timing maps are set at, then be very wary of making ANY timing adjustments.

WOOT tass replied, i knew you would come at me with the goods.

thanks heaps man, u really know your stuff.

now to really annoy you, i dont have the hand controller for the mt8 computer, is it possible to adjust the timing at all without going through the computer, or would i HAVE to go to a tuner and have them do it?

only reason i ask is because its not running as smoothly as i would like at the moment, and i have a strong suspicion it is because of the timing.

so all in all, is it safe to retard the timing a little bit without touching any of the computer, or do i stay away like church on sunday until i can get it to someone with the computer to do it ?

Hey PJ, I've just moved up this way and should have all my tools up by the weekend, I have a timing light amongst other things.

Not too bad a deal.

no dramas checking the timing but unless you know exactly what your maps are then you can only guess at it all.
