Hello all,


I've got a problem with my (stage 1) Escort Cosworth (P8 ECU). My Escos doesn't pass the Dutch MOT (APK) because the CO level is to high (3000 rpm 0.97 wich should be 0.39). I run a turbo back Magnex in wich i've welded a 3" racekat.

As the P8 ECU doesn't have a mixture ajustment screw i thought of fitting a L8 ECU (only for the test). I've been told the L8 ECU does have a mixture ajustment screw, swaps straight on with the P8 ECU and can run the "P8 Escos".

Do you know if this is correct? I could also try to find a standard chip but i don't know any (i'm in The Netherlands) and i do know a standard L8 ECU.

Regards,



Mark

 

The ecu's can be swapped straight on.
Only the P8 uses a 2.5B map sensor and a L8 2.0B map sensor.

 

Thanks for the quick reply! Would the MAP sensor cause a problem?

 

Yes would be best to swap the map sensor aswell.

 

Ok, thanx. Could i also fit the ajustable Sierra fuelpressure regulator to reduce the CO level? Instead of changing the ECU and MAP sensor?

 

You might even try a fuel regulator from a rs 2000 that's a straight swap to a escos fuel rail I believe it's 2.7 bar FPR.
It could help for MOT but don't drive it hard with it.

 

Thanks mate, yesterdayevening i've picked up a L8 ECU and a 2bar mapsensor.

 

And today my Escos passed the Dutch MOT; CO 0.08 and Lambda 1.06 .Thank you again!
