16M tunnel loom going in. It contains the power source & relay part of the secondary air injection electrical system, and the fuse and two pin power supply connector for the ion module.

I've gained a 40amp Maxi fuse and a black 50amp relay (not the red F1 relay next to it that I accidentally identified with the green arrow!) for the SAI system. F430's are built with a spare mounting stud for the SAI relay because emissions standards in some markets mean the system is required. The Scuderia Bosch engine ECUs are now installed - note the 'F131LP' code on the left bank ECU in shot, and also the E-Diff module.


F131 = code for the original 360 chassis ;
E = 'Evoluzione' (evolution) - the modified chassis for the F430;
LP = The Scuderia code suffix. I don't know the official term, but I estimate 'Leggero prestazione' (lightweight performance).

A very minor point; I tracked down the fuse type that Ferrari use which feature an opaque rather than translucent plastic shroud. The manufacturer is MTA, Italy.

Interestingly, the Scuderia uses aluminium rather than steel brackets for the electrical modules. They are, of course, lighter! I have swapped my original brackets for them.

All in the conversion to Scuderia management is weight neutral, so I haven't recorded everything in my sheet: the F430's four knock sensors with shielded wiring back to the ECUs, and heavier steel brackets that were removed are offset by the Scuderia ion module and relay loom. I think that's excellent given the significant improvement in knock detection.


I estimate a relaxed weekend's worth of work away from testing the new management - I can't wait for that.


N.B. excuse the low quality photos.
