i have been asked to supply the parts required to fit power steering to a cinquecento

on the list already is
pump
lower column
rack
ecu
wiring
column stalks?

Reading through other posts there is mention of a speed sensor? where does this go?

Also people say the top mounts (on the suspension struts?) are different. A bit of info on how and in what way they differ would be useful. What could be the outcome if using standard 899 cinq top mounts instead?

Thanks for any help. I'm helping an older driver with arthritis who has just bought a cinq all kitted up for towing behind his motorhome and is really struggling with the parking

Thanks
James

No pump, no need for rack or mounts.

However, you will need to reconfigure the dashboard as the motor will foul on the bottom of the cluster.

Speed sensor can be controlled by a rheostat that will adjust the steering.

Craig has the wiring diagrams

the power steering on the seicento's are done by the column and its electric so no power steering pump for fluid

these is a few threads around here giving out quite a bit of info

the top mounts change the geometry of the suspension, are stiffer and quite a bit more expensive, the steering rack aswell on the seicent'os equipped with PAS are 1 turn quicker from lock to lock

EDIT: aww beat to some of it

Sorry when i said pump i meant the motor on the column

No need for rack? they differ and will it have effect?

"Speed sensor can be controlled by a rheostat that will adjust the steering."

ok, where is the speed sensor on the seicento? all i need to do is pick it up..

Who is Craig..?

Any specifically on putting ps in a cinq? i could find a couple but not with much detail. I really need to know which parts to pick up as i am breaking a sei sporting and posting the parts off

The only difference between racks is the number of turns lock to lock. The power column will work fine with the cinq rack.

Craigb244 is the screen name of Craig who has done the conversion.

Speed sensor is in the gearbox in place of the cable. If you use the Sei speed sensor you will lose the cinq speedo.

If your customer is happy with a single layer of assistance you can use a single clock chip.

"If your customer is happy with a single layer of assistance you can use a single clock chip."

Can he use the existing speedo cable?

James

Either/or, not both.

Use the Cinq speedo cable to drive the cinq speedo.

or

Use the Sei sender to keep the power steering variable, therefore no speedo.

ok, so long as the ps will work without the speed sensor. will it stay on it's lightest setting (as if going slow) or be more weighty (as if having sped up)?

Thanks
James

the sei has electronic speed. no cable. A sensor is screwed into the box where our cable goes.
but I wouldnt worry. as long as the ecu gets an engine running signal (connect the wire to the fuel pump cutout switch behind the dash) it will work.
I found hardly any noticeable change in assist from full to low. and car does not feel over assisted at high speed.

you also need a sei steering wheel.
and make sure the column has the shaft on it as the cinq one is not the same.

fitting requires a lot of changing.
the peddle box needs tweeking as the support/brake light switch is in the way.
as david said, the corner of the dials foul the motor meaning you need to cut it (loose the yellow code light iirc)
the ignition barrel does not fit at all. so needs to be relocated (i liked this as it means mines hidden away but wont mention where on a public forum )
because of no ignition barrel you loose the steering lock.

the stalks require a lot of rewiring (they will replace a couple of the dash switches) and NON of the wire colours match the sei column so requires a lot of work. but I have a excel i made to help with that if needed

Thanks Craig,

'as long as the ecu gets an engine running signal..' that's the ps ecu i assume?

If you're happy to send me a copy of the wiring for the stalks i't be much appreciated!

Thanks
James

with no speed sensor input the pas ecu will think the car is at standstill and apply full asist

yes pas ecu

ill pm you the files I have but if anythings wrong or causes the car to catch fire I cant be taken responsible or help (hence why ive not made these public because I can imagine non stop "HELP MEEEE" PM's plus its messing with important wires/very high amp-age wiring/steering/brake/clutch peddle not something you can bodge together)

Yep. Understood

difference with the top mounts is that the PAS ones make the suspension stick forward slightly and the non pas ones make the suspension face down

e.g....

/ = PAS | = Non PAS

Thanks Gaz

That's worth knowing.

i take it this elderly person will be taking it to a garage to fit?

tbh i would reccomend to them to get a sei and kit it up for towing

yeh i already suggested that would be a better way, but he has just spent £900 on this (with the installed towing gear etc) and can't bring himself to sell it and go through the hassle again.

He is friends with a local police mechanic who says he'll have a look, so hopefully he'll do a good job

Is this the same power steering that is in a fiat punto mk2? I thought the PAS ecu gets all the data from CAN bus?

It's similar, but Seis are refreshingly unpolluted by canbus.
