Does any know if a crank sensor can be piggy backed ?

 

What do you exactly mean by this ?

 

incase one fails possibly bit like rally cars running 2 ignition amps and map sensors that I have seen

Can i plug the ecu and the rev counter into a single crank sensor?

 

what you trying to do??

i presume you mean to power the st170 dash, ie you want to split the analogue sine wave output of the ford crank sensor and have one wire going to aftermarket ECU and the other to the original ECU to power the dash.

 

Yeah split the signal to the ecu and to the dash off the 1 crank sensor? can it be done? or is it best to keep them seperate?

 

I think will tried to do that and found the signal wasnt strong enough. You can try it for sure.

 

Wont you need the crank sensor from the focus anyway or are they the same?

Get one of those wrc crank sensor brackets and mount the two!! Seen a pic somewhere!!

 

I have done it on my Car the single crank sensor feeds the Haltech and the stock ford ECU, as the ford ECU is used to run the Clocks in my focus RS

it works fine.

 

Should work perfectly, if not just amp the signal, or graft another sensor on for the rpm read.
tabetha

 

done it on an omex and a transit connect ecu.

worked fine

 

so Will was just unlucky with his car then

 

I think ill simply run 2 seperate crank sensors , one for the ecu and one for the dash, NO confusion that way ;o)

 

The wrc crank sensor bracket mounts at 180 degrees from the standard one, (imagine 10 oclock location and the standard at 5 oclock) if you plan to use one you need to modify the alloy front crank seal holder (the one that bolts to the sump) so that it does not foul the bracket (easy to do and obvious where, when you try to fit the bracket), you also need to use a 4x4 water pump as it will foul on a 2wd pump as one of the inlet pipes gets in the way.

 

Have a look at this post i think it wot you are looking for mate

Simon, does the Focus dash normally read from a 36-1 trigger wheel as I assume that's what your using?

Personally I would not piggyback any sensors and risk something. Was advised this by Pectel when I looked into this before.

I have no idea what the Focus dash counts in the first place so difficult to say.

 

Yes the focus dash does read 36 - 1 , and i think it also uses a focus cam trigger aswell (but not 100%)

Im using an Escort cosworth T25 36 -1 crank pulley and
ive decided to keep everything seperate and not piggy back sensors ;o)

 

Good choice!!!

 

Yeah definatly gonna stick to the K.I.S.S theory ;o)
