2001 C4S Cab - Does this have E-gas?

[Richard Hamilton]

This is a UK specification 3.4 litre pre-facelift 2001 model C4S cabriolet. Does it have fly-by-wire throttle, and hence is cruise control retro-fittable?

[Loren]

All C4's regardless of year are egas. The only not egas 996 series car was the MY99 C2.

[Richard Hamilton]

Is the cruise retrofit fairly straightforward then? I have seen the Boxster retrofit instructions - any pointers for the 996 anyone?

[Tool Pants]

Looks like there might be a third cruise control retrofit in the works.

Look at your 1998 wiring diagrams and see if there is any difference with Ed's instructions. I'm sure the DME version changed but I do not know if the wiring changed. Then you will need a PST2 to turn it on. ;)

Thanks Jeff

It is a friend of mine who is interested in doing the retrofit on his C4S. I don't think it is a practical proposition to do it on my 98 C2. It seems like the C4S should be fairly straightforward provided stuff like the clutch switch is fitted. We need to start crawling under the dash.

If anyone has actually done it on a 996 it would be useful to hear from them - especially if it was a RoW model. P. Viby perhaps?

Jeff or Loren - Is the Motronic version the same on a C4S as an egas Boxster? (I think it is 7.8 on the later 986 Boxsters). Unfortunately I don't have the wiring diagrams for the later cars - unless anyone can oblige?

The first year for C4S cabs is 2004

Sorry, it's a regular C4 Cab - wishful thinking on my friend's part!
