Little tinker update..
After seeing lots of PAS steering pumps popping at the track I decided to remove HPAS in favour of EPAS.
It was a very difficult decision to b fair, but whilst I had the car apart to do the clutch AGAIN (will talk about this after) I decided to ‘simplify’ my bay.
I used the PMS pulley and removed all pipework, pump and blanked off the rack. Fitted the EPAS column and wired up using high quality cable, connections etc. All powered from a bulkhead connector direct from battery. Lovely!
After initial drive felt good, then realised that the standard pinion inside the HPAS rack gives a horrible disconnected feeling when pushing on through corners etc… car wonders around because of the 2piece construction.
Sooooo, I ordered up a PMS quick rack kit, which has a solid pinion. Fitted all that did my setup again and took it around the block on a test drive, now I have ESP cutting in whilst giving small amounts of steering input.. carried out some checks, reset angle sensor etc. But found what was actually happening was the car was seeing less input from steering compared to what the YAW sensor, wheel speed was seeing due to the increased ratio of the rack!

Spoke to Nick at pure, and basically these racks aren’t generally fitted to road going cars with all the systems in. So I needed a work around, even with ESP off by the switch an element of traction control could still be found so I had to reconfigure using clip, remembered from ages ago it could be done so now traction control is permanently disabled retaining ABS so all lights correct for MOT’s
Anyway… a small job turned into a bit of a nightmare! All fine now albeit taking some time to get used to the smaller amounts of steering input with 372hp in the wet [emoji23][emoji23][emoji23][emoji23][emoji23][emoji23]
