F40 distributor sensors

I put the part number in a google search and up came red parts in france, stock nil but acvailable in 10 days ?

 

Do you have a pic of one, just wondering what you get for such a steep price. F40 is a bit more than i can afford

 

I have a couple of spare cosworth distributors somewhere, can post one to you to see if any parts will retro fit regardless.

edit

scratch that idea sorry, went out to my shed to find and photograph one, as I have about 5 in a box, found plenty of ecu, ignition amps, map sensors etc but not one dissi! so must be sat in a 20' container with all my other bits and bobs which I wont have access to for a few months now sorry.

Lots of YBs with the weber ecu have now gone over to distributorless, might be on option for your project car, not so much for an original though.

 

Is this thing just a bracket with a coil and a couple of wires to trigger the ignition ? If so i have an idea of who could make them

 

Assuming you mean this?

Ford RS Cosworth Sierra Escort Distributor Phase Sensor- Magneti Marelli 7132690 | eBay

If so could you not take the actual sensor off the cosworth version and attach it to the base plate from the F40 type?

On the F40 it just reads the phase as I just realised they do not have distributors.

 

Makes you realise the mark up if that is similar to the f40 part. Ie 15 x times the price

 

PARTSCOLLECTORS RICAMBI CLASSIC FERRARI ANSA CARELLO LAMBORGHINI ALFA ROMEO

They list both as available

 

Hi Red Sled,
I have the same problem like you, I think. Can you tell me your experiences with the "Ford RS Cosworth Sierra Escort Distributor Phase Sensor Magneti Marelli" in the F40? How many kilometer have you driven so far with this sensor?

Maybe you can tell me how you transplanted the base? Are you sure, the winding number of the coil is the same on the F40 version and the cosworth version?

I've added a picture of my Sensor.

Hope you can help me.
Many thanks and greetings from Germany

I had the same problem with my car, i have successfully taken the coil off the cosworth sensor and installed it on Ferrari bracket.

The easiest way i found to do this was to drill and tap the metal post of the new sensor(where its riveted to the bracket and needs to be drilled/ground to remove) and then mount on ferrari bracket with a 3mm(or may have been 2.5mm...) machine screw and high strength epoxy. This method ensured proper alignment and there was enough adjustment to set air gap correctly.

I can't remember which wire colour went to which(there were colour differences between the 2), but that can be confirmed with a scope or with a simple diode....although being a sync signal the rising or falling edge may not cause it to fall outside timing window.

Coil compatibility is fine.....it just a low level reluctor signal and it is giving a signal to the same Weber IAW ECU.

Car has been running for a year like this.....this how ever does not equate to a great deal of kilometers !

 

Thanks a lot Oversteer40 for your response.
I've ordered the cosworth sensor from GB. Now I have to wait for about two weeks.
I'll let you know, if the transplantation worked.
My idea was to grind the coils off their groundplate and secure the cosworth coil on the ferrari ground plate with a welding spot.
Hope the plastic and the coil wont get damaged by the heat.

 

Many thanks for your advices. I'll heed them.
Hope everything will work fine!

 

Yeah my first choice would be to weld it back on, but i didn't want to melt the plastic of the coil, maybe a spot welder, or a quick touch with a mig ad dunk it in water might work ok....what type of welder did the shop use Red Sled ?

I ordered the senors from https://shopbhp.com/collections/engine-parts/products/cosworth-yb-crankshaft-speed-sensor-sen8d , only took 4 days from UK to Australia, they have many other compatible parts for the F40, temp, MAP sensors etc

 

Drilled and tapped the metal post that goes through coil(the bit you grind off bracket)...very small tap which is delicate, but not that hard to do with a quality tap and a bit of touch.
Then i used a little bit of Devcon(High strength, High temp metal epoxy) to mount sensor and secure machine screw.

 

Just looked through my photo's.... unfortunately i didn't take any of that operation as car had to go to dyno and be ready for track day in 2 days....

Only picture i took was for Motec guy ;

IIRC as well the 2 pin connector plugged straight in and it may have been only one way too !

 

Finally I've changed the sensor. Unfortunately it was not the main source of error. Tested the signal with my oscilloscope and the signal looked great. The air gap as Red Sled told is between 0.2 - 0.3mm.
The left cylinder series dont work. I'v new spark and saw them working, but I think the left side of the V8 does not ignite.

 

Possible an ecu issue, swap left to right and see if the fault follows.

Having a ecu diagnostic tool would help a great deal also.....would show exactly what the ecu's see/are doing.

 

On the cosworth version of that weber ecu you can tap into a couple of the wires in the loom with a bulb holder and a couple of wires and it blinks a series of flashing codes that relate to various sensor faults. Maybe its also possible on the F40 versions. If you take a look on the bigturbo website that redsled listed it should all be on there.

 

Don't believe that's possible on the Ferrari version of the Webber IAW, Ferrari uses there own unique firmware which has more detailed diagnostics, but no check engine light like the cosworth version.

You need to find someone with either the Ferrari diagnostic scanner or something like the RPLabs Diag cable&software.
If where you live its anything like the Ferrari dealers here their old school dig tool stopped working years ago and it was all guess work !..... so i bought the RP Labs equipment, big help being able to see ecu data stream and sensor voltages etc, logging also possible but crude ....but it was 1987 !

...swap ECU's left to right and see what it does....
