timing tuning problem

[filh]

hello
[u:83afd0cede]To Jondee[/u:83afd0cede] : you're right the timing measure was done without any load .
But My machinist has a Dyno Bench and He may be refering to measure he did with cars on Dyno . I think my oem ECU works normally .
I'll try to do some measurements , without vacuum sensor hose disconnected .

[u:83afd0cede]To Robokill[/u:83afd0cede] Correct , I'm using Catcams and stock grey injectors .
The machinist gave me an Air Fuel Ratio Meter(Lumenition) to test the ratio , and it looks like it's correct or a little rich at +/- 6000rpm.

I've set the timing round 7° at idle with Diagnose connector jumped . Don't know how much without jumper .

And I finished my rally race without any trouble at all . T°always ok , oil pressure ok and no oil consumption .And as I had no time to , the engine had only 200km before starting the rally .

there were 4 AE86 at the start of rally , and we all reached the chequered flag

I think an incorrect timing is more sensible on races engine , as it's so often a WOT use

Anyway , thanks for your advice
