Rs Turbo Ecu

[a1dale]

i have a mk4 escort cabby which has the s2 rs turbo engine fitted

 

i have done mods to it but now i need the boost turning up so need a chip for the ecu

 

the cheapest and easiest way of doing this i found is to replace the ecu for a chipped one

 

these are easily obtainable off ebay but non have my code BLUE RED WHITE

 

i have heard these can be interchanged but there is some complication between if they have a knock sensor or not

 

my wiring loom does have an knock sensor plug but the engine does not have a knock sensor so its not plugged into anything

 

so what i was wondering is what if any ecu i can use on my engine?

 

Thanks

Its not worth bothering to get a second hand chipped ecu. It may be faulty, it might not suit your spec and it could be a bad map.

 

It needs to match the type you currently have. There a 4 variations. I would reccommend getting the chip from MSD, they are one of the best and only around £150.

 

You can fit it yourself if your handy with a soldering iron. You then need to get the car setup as you'll soon destroy the engine without the fueling and timing adjustments.

 

When knock sensors get old they start resonating when the engine isn't knocking and retard the timing. Unpluging it will stop this but then if your engine does knock the ecu wont know which could end up bad so it worth getting one that works.
