Hello again!

i had some problems in january

https://passionford.com/forum/viewto...702&highlight=

And i changed the fuel distributor, but the ecu still needs
that vent so it works.



I have changed following parts:

Fuel distributor
Ignition distributor
Ecu / and jetronic box
Throttle position sensor
Air tempeature sensor
Fuel filter
spark plugs

ecu is chipped now.. when i remove the vent from ecu's pipe the ignition advance goes erratic on boost. It has no power at all.

Timing advance is 9°, i also tried 11° but it knocks 4 and fifth gear.


Setting #1
When i tight the ecu pipe vent ( less pressure going ecu) car runs better and has more power but knocks easier.

Setting #2
I open the vent ( more pressure going to ecu) not knock at all, but no low rpm power.

Yesterday i tested 8° ignition, and open the vent more..
1.0 bar and not knock but low rpm and vacuum car is like corolla, no power at all.

What should i try next?
