Hi all, what is the purpose of the vaccum pipe going to the ecu?
Is it just So the ecu knows when to turn the amal valve on/off?
If so im not using amal, i running a bleed valve so i could get rid of that hose as its one less potential air leak?
Thanks

 

it connects to the internal map sensor
DO NOT remove it

 

Okay, thanks i wont

 

Yes otherwise the ECU will not see any boost/vacuum and adjust the timing accordingly..... Detonation and a dead piston or two would be the result!
