ill try on here.....
i have an escos big turbo which is flooding heavily and filling the bores up with fuel.ive replaced the blue temp sensor,whilst off the road we have gone with light blue injectors with a collins chip to run it with standard map sensor.if i disconnect the injectors it will run briefly while it uses the fuel in the cylinder,but if i reconnect them it just cuts out and floods badly

any help would be great

u say a collins chip... what map sensor and injecotrs is the chip designed for,

the chip doesnt know WHAT u have connected to the ecu, so if the chip is programmed to open the injecotrs for 1ms each at idle ( say std dark blues) and u have much bigger injectors in there ( light blues) that the chuip has been written for(possibly stg 1?), then it will put much more fuel in there than its supposed to, similarly with the map sensor, is the chip is expecting 0-5vdc from a 3 bar map sensor and at full range (ie 2 bar gauge) its fuellnig at full capacity, but in fact you have the wrong sensor , a std 2 bar item (and its giving the same 5vdc but at only 1 bar gauge) again it will cause massive overfuelling.

u need to speak to collins and check exactly what the chip has been mapped for

 

the chip is for the light blue injectors as i got it from collins yesterday,she told me it was designed to run with the standard 2.5 bar map sensor.i had the problem before fitting them when it was stage 1.

 

only really one thing it can be then , it all teh rest is matched, and that is fuel pressure, if there is a kink or blockage in teh return line to the tank teh pump will pressureise to its max pressure and when teh injecotrs open , instead of 3 bar behind them, there may be 6 bar behind them.

 

Coolant Temp Sensor and/or Wiring Checking - info courtesy of Simon @ SECS
1) Ensure ignition is OFF.
2) Remove rear of ecu plug cover and insert plug back into ecu.
3) Turn ignition back on (do not start engine)
4) Check resistance between pins 29 and 11. Should be 800 to 5000 ohms (depends on temp). If outside this range, check sensor and/or wiring.

 

how do you count the pins?

 

the housing is numbered

 

youre right it is.....ive just done the check and it seems to be open cicuit.cant see any fault in the wiring but it is all brittle so ill call it a day for tonight and start again tomorrow but ive just spoke to a mate who has had a coolant sensor fault in the past which filled up his cyliders with fuel,thanks ian

 

did this ever get sorted?
