Hi all,

I have a MK4 Cabbie which I've converted to an RS back in August.

My other half bought me a Chipped ECU for Christmas. I put it on and the car wouldn't run at all. I found out the chip causes the electronic timing to be well off. Instead of 12 degrees it was running about 4. When I put the strobe on it with everything connected the timing mark hardly seems to move reagrdless of what RPM the cars running at. I set the timing mark to 12 degrees by altering the dizzy and seems to be running ok.

My question is, should I need to alter the timing as much as this when swapping the ECU. I have heard that it shouldn't be like this but i'm not 100% sure.

Any help on this would be appreciated.

Cheers
Dave

 

some rs turbo ecu's can have the timing changed internally by the tuner who is installing it to suit the need of the setup of the engine

 

You have either:

1) A dead ecu pressure transducer.

2) Squashed the pipe when youve installed the heater box back in

 

As above,been there, done that,got the tee shirt Dont forget to pipe the ecu up,that wee vac hose tends to suck air just a tad.

 

HI,

ALL ABOVE, BUT IF YOU NEED ANOTHER ECU I HAVE A SUPER CHIPPED ONE.
