I have just fitted a stage 3 chip to my escort cosworth, with the standard injectors it runs fine but as soon as you put the greens in it appears to pour fuel in so much so that it is washing all the crap out of the exhaust and pouring smoke out. The esc is running a L8 ecu with a MSD chip that came from a 4x4 saph, Any help or advice would be very greatfull.

 

why have you got an l8 in an esc cossy?

 

Has it got the right map sensor for the chip?

 

sounds like no 3 bar map sensor and wrong ecu for the car (pretty sure a L8 will work though buy not defo 100%)

 

what ecu is in an escos?

 

P8 in a escos L8 in saff 4x4

sounds like wrong map sensor to me, which one do you have 2 bar or standard escos one which is 2.5 bar ?


u need a 3 bar

but why a L8 in escos ??????

 

I have a 3 bar map sensor fitted. I am using an L8 ecu as I had problems with my P8 and at the time was all that i could get hold of. The L8 has been in the car for about 2 years now with no problems to date.

 

check your Co, and are you running a lambda sensor?

other thing is fuel pressure..

 

Have tried adjusting the screw on the ecu but with no change, the car is running a lambda sensor, the fuel pressure is fixed on the escort there is no adjustment on the regulator.

 

Speak to Stu@MSD - the chip may not be suitable for your Escort's spec' - that's aside from the overfuelling issue.

 

Had this symtom on a 4x4 i tuned up turn out the map sensor had water inside

Due to the fact i done the cam belt and drained coolent went on sensor from header tank

took me ages to find out

NEVER ASSUME THAT NEW PARTS ARE OK!!!!!!!!!

Big lesson learnt that day
