timing tuning problem

[filh]

Hi Guys , Having some trouble with the timing tuning on my lightly modified 4age ( in/ex camshaft 256°
.As some known I use my ae86 on rallye here in Belgium .

Here's my problem : I know the process to tune the timing on a 4AGE .

Shorting the diagnose connector , T and E1 , setting on 10° at 800 rpm etc etc ......
But does anybody know the timing advance at 5500/6000 rpm.
Doing the process as described above , I 'm having 44° at 5800rpm!!
That sound much to me (too much?)

My machinist say it's far too much , and set the timing at 29°( always at 5800rpm)
Result of this : at idle(1000rpm) without diagnostic connector shorted timing advance is 7° !!
On road , that's not very expressiv........
Any experience welcome .
I'm still having the stock injection , with stock AFR . And the air /fuel ratio is ok .
I'm in a hurry as my nex competition is on Sunday....
Thanks
