Hi,

connect Multi ECU Scan, and see if the Cruise icon lights on the Dashboard,

I tried this on my 110 JTD = no icon ,
system does not support CRUISE from the factory


g8rpi tried on his marea also,

to confirm;

my july 2001 build 110 has the #46817802 ECU

and MES get's little activity in enabling cruise:bang:

are you unable to do your own research? it's been 3 months since this thread was started, and we have shared the extent of our knowledge, have you nothing to contribute yourself?

most cross referencing comes from Alfa . Lancia of that era,

I've given up with cruise on mine - shame as that restricts when / where I can drive it..,

Charlie

I decided to do it myself.

I am researching information about the accelerator pedal potentiometer.

The pedal unit is two potentiometers if I remember correctly. If you make pedalbox, you need dual digital pots with right values (measure yourself, Im not sure if it).

One reason I just connected servo to it, no direct electrical connection to the ecu and I can override the servo just by using my foot (more throttle or disconnect the linkage incase of unwanted acceleration).

Also:

Image is from rev1, rev 4 boards are on mail and they use 3110 lcd so I can replace the cars own odometer with it. Info from ECU is more precise than the signal behind the radio.

Is it direct connection pedal potentiometer with ECU?

I'd spotted this set - looking to cross reference the "other option ECU"
http://www.ebay.co.uk/itm/Fiat-Mare...:Marea&hash=item4d19c43a13:g:xv4AAOxyni9TFZM6

but this had a RED ( brown) key.. serial No.#----5080

WEIRD I thought ALL Marea's were the modern system..
my 1999 105 had 2 x full remote keys

I got my project from earlier post to pretty much done.
Cruise on 155 HLX weekend (little speedo with arrow on the "odometer").
Currently only on membrane switch, but I got BMW E66 cruise stalk that fits under the indicators.
Throttle is actuated by servo on the pedal as 155 is fly by wire throttle, but it is more precise than using my foot on small movements.

thanks for the reply..
I don't fully understand what the 1234 membrane actually does..,

but the cruise icon on the LCD panel - I'd not consider looking there..,
I'll have to reconnect MES to my JTD..I was looking for a lit bulb

1234 is just the default membrane switch logos, they are: Stop, Start/set, - and +.
As for the cruise icon, that is all custom, the original odometer has been replaced by microcontroller+lcd that talks to the ECU and has cruise builtin.
Nothing on the original ECU.

My understanding was that all *facelift* models had no red key, my TD100 certainly had a red key.

Might need some of your experiences with my quest for cruise..

You mean me? Or someone with Lybra ECU cruise builtin?

Also here is picture of the stalk installed.

Not the greatest on hilly terrain as it only updates ~1.5 times a second because the communication to the ECU is not the fastest. Cruise might run 3x the speed if the speed/fuel consumption is disabled to reduce the message count.

Im still looking to retro.fit cruise to one of my older cars..

Garages are quoting @£500.. the value of the cars..


Found a 'kit' for @£180..

Might consider it.. then attempt to clone it for cheap onto a grande..

Somebody used a basic touchpad controlled system on a bravo-marea on here a few years ago.

I already retrofitted Cruise Control to my 2.0 CF3 marea. I used alfa 156 CC switch, which suit marea stalk - there are even holes for screws ! There were necessary to make additional connections from switch to ECU. Brake switch need to be changed to 2-contacts type from Lancia Lybra, or do a simple trick with ECU wiring. As cruise control lamp I used "injection fault" diode, because my version of car is already CF3 EOBD (check engine diode present), so it stay not used. The main problem was ECU - cruise control was internaly disabled by software, so when I connected CC switch, ecu recoginzed signals, but CC stay "not availabe" in diagnostic status. Fortunatelly I found all bytes (actually 2 + checksum), which are corresponding for CC. After that, all work fine. If someone is interested I can make a video about working CC.

It would take more than a button..or lever to help my old JTD maintain 70mph
