the ecu power pick up point is at a distribution point under the bonnet,
shall i run a fresh cable back to the battery which is in the boot?
not sure if it may help with sorting the spikes etc.

never looked mate, to be honest.
BUT i have done most the datalogs from start so it should show in the log,
i'll run a new 6mm cable from the battery to the ecu this weekend then,

As a matter of course with rear mounted batteries we run a 6mm wire to the ECU, Injectors and Ignition via a relay switched by the ignition switch on the key barrel.

i have a ignition switched relay from the key that energises the fuel [pump and fan relay, and the main fuse box for the ecu,
the main 12v power for the above comes from the distribution box under the bonnet from the battery via a 6mm cable now,
BUT as previous post i will re run a 6mm cable to the above direct fromt he battery instead now and do away with the under bonnet feed,
that will have to be a job for the weekend,

Oh arse :(

We're going to have to fall on the gods of mercy and dnb to look at this directly.

Point of interest is the complete lack of resets in that datalog.  Which is an ecouraging sign.

The red lines in that other datalog are resets.  Didnt see too many obvious spikes either...

Well we'll see when you put the accel bins back.
But I doubt it.
