advice needed
 
Some advice needed regarding the electrics if at all pos, my loom for my 1.8 cvh was a mess so trying to go it alone. Does anyone know via a diagram or a description in laymans terms how to connect up the lambda sensor and coil via a switched earth to get her to fire. Any help would be really appreciated many thanks in advance?

Very kind thankyou but my loom isn't in the best of nick so not really an option was wanting to try to creat the switched earth manually if possible.

Do you really need the lambda sensor connected to get it to fire? Sounds like you most likely have the same loom as me so have a look through some of the electrics threads that I've started when I was trying to get mine going.

thanks
 
Cheers will have a look at thread but was under the impression that the lambda sensor controlled the switched earthing of the charging and releasing of the coils energy.:eek:

I'm not sure on that one but I managed to start & run mine up with just the edis in limp home mode without the ecu or any of it's sensor connected.

The spark timing is via the crank position sensor.I think from the ecu via cps.I too found it difficult to sort out but then the eureka moment came .Its fairly simple once you can get your head round it

You should just sack off all of the standard ecu and go bike carbs! much easier from a wiring standpoint, more power, and it fits under the bonnet much better with no holes etc needing to be cut as I found the CFI unit quite big and didn't fit very well. Not that expensive either as you can pickup most of the bits off ebay quite cheap ;)

oops
 
Sorry been referring to crank position sensor as lambda question might make more sense now

brainbug007 13th April 2012 05:25 PM

Ah that does make a bit more sense now! I haven't got my trusty haynes manual to hand but from memory the wires for the crank sensor just go directly to the edis. The edis should also have wires going directly to the coil and it's suppresor. Then there's another set of wires (inside a shield like the crank sensor wiring) that should go to the ecu but as mentioned previously that doesn't need to be connected to run the engine in limp mode. Other than that I'm pretty sure there's just an earth wire from the edis which you'll need to attach to your chassis somewhere and a switched live feed that comes from somewhere in the fusebox. I think the coil however gets it's power feed from a funny looking plug which is on the body loom for some reason. there's a picture of it here http://www.haynes.co.uk/forums/showp...44&postcount=1 in the 2nd picture down the the number 203 written on masking tape.
