Will Pedley Racing – Focus ST170 ITB conversion

Unfortunately the new ECU didn’t like sharing the crank sensor signal with the OE ECU and so wasn’t able to introduce an adequate data signal into the CAN Bus system for the tachometer to function.


Clocks out:

Dismantled and tacho removed:

Careful measuring and a hole saw later…

Then the white casing underneath got the holesaw treatment:

Unfortunately my phone battery died at this point so there aren’t any more ‘in progress shots’… But after some black fablon and careful cutting, some tricky wiring and a few other odd jobs – the rev counter problem is fixed 😉

Those of you that have known me for the 5+ years i’ve been on here will surely remember that performance tuning is all i’ve ever wanted to do and now i’ve finally built the knowledge base i’m just an enthusiast trying to help other enthusiasts and put my food on the table as a result.

  1. Brill write up, fantastic even, so glad that this has been looked at before I venture down this road,

  2. Hi Jonathan,

    Glad you like it – I’ve merely borrowed the content from Will Pedley a means of showing the importance of Search Engine Optimisation – although it is my car!

    If you’re looking to do something like this I would say without hesitation to give him a shout http://www.willpedleyracing.co.uk 🙂

    From your e-mail (which isn’t shown to the masses) can I assume you have a Fiesta? I can only imagine how quick a smaller car would be with this engine :0)
