starter ikke

[Guest cosworth24v]

hei kjøpte meg en chip, satt den i å vrir om tenning i håp om å få d litt morro,men hva skjer den starter ikke å i forbannelsen setter jeg inn den orginale feil vei i tillegg. snudde den orginale riktig vei men nu starter ikke bilen mer... noen forslag hva jeg må ha nytt styreenhet eller chip?

jeg og en venn satte en chip feil vei i en volvo 940, den gikk som en lada da snudde den og alt var ok.

vet ikke hva som er feil men tror ikke noe skal være ødelagt..

du er sikker chipsen var til samme ECU - de går ikke om hverandre ...... og nå må du skaffe deg en ny/ feisøke på alle giverene ........

 

 

ECU types used in Sierra (RS) Cosworth:

All type of Sierra (RS) Cosworth use a Weber Marelli type of ECU (Engine Control Unit or motormanagement) however, these ECU's have changed over the years as demands grew and computer technology improved.

Although, as far as known, all ECU's use the same connector pin-out (und thus can be electrically interchanged) one can not use for instance the latest ECU on the earliest Cosworth. This is because the ECU is fully "tuned" to the engine characteristics which have dramatically changed over the years. The latest ECU's also use input from several additional sensors which are not available in older models.

Here is an overview of ECU's used and how to recognise them:

 

Level 1:

Used on the RWD hatchback RS Cosworth, has 64Kb of memory. Can be recognised by the mounting flange on the front face and a yellow CO adjustment screw.

Level 6:

Used on the RWD sedan (RS) Cosworth, has the same capabilities as the level 1 model but uses totally different electronics. That's why Level 1 and Level 6 chips can not be interchanged.

Can be recognised by the mounting flange on the front face (like the Level 1) and a white CO adjustment screw (Level 1 has a yellow one).

Level 8:

Used on the 4x4 sedan (RS) Cosworth, has twice the memory storage capacity (128Kb instead of 64Kb) as Level 1 and Level 6. That's why chips can not be interchanged.

Level 8 was available in 2 type since the engine in the 4x4 was available with and without hego-sensor (i.e. with and without catalytic convertor).

Can be recognised by not having mounting flanges and a green or red label with WD48.08.

The one with the green label and second code IAW048/01 is for the catalytic convertor (US83) model.

The one with the red label and second code IAW048/02 is for the non catalytic convertor (15/04) model.

It is uncertain if units/chips can be interchanged between red and green types/engines.

There are also Weber Marelli P8 (no flanges, white label IAW48/P8) and Ford EECIV (totally different from Weber Marelli, central bolt to hold connector) ECU's around. These are however only intended for use on a Escort RS Cosworth but you might find them in some motorsport Sierra's (RS) Co
