m49 cruise control retrofit............

[javizzz]

hi, guys..........!!!!!!!!!

im searching for some info about retrofiting cruise control on my m49 berlingo (ecu edc15c7 and NO bsi onboard)............

that could be posible?????????

i cant find any wiring diagram or something that leads me anywhere, just retrofits for for the m59s..............

What engine do you have in your Berlingo? I might be wrong, so am happy to be corrected but I think the BSI is key for the CControl to operate. There maybe a different way of doing things on the M49. Does the handbook for your car show CC?

hi.........

mine is a 2.0hdi, and it has NO BSI, just fuse box............

also, i took the steering wheel trims, and there is no sign of the cruise control stalk nor free connectors for anything............

i think i must wire it straight to the ecu and maybe turn it on, but i cant find any wiring diagram ANYWHERE.............

Any body know what the part numbers for the accelerator pedal needed to retrofit cc, and any other bits which may need to be looked at/upgraded?

type...throttle pedal in search............u will find wot u need

Thanks, I had seen this post, but there wasn't any part number listed for the pedal, and I understood there where other parts needed to get it all ready for installing the software to get it up and running

I don't think there was a fly-by-wire throttle available for the M49. You need that as a minimum. Any car with cruise had FBW throttles or a complex motorised throttle body system was needed for cruise, like early cruise control on XK Jags. The ECU & BSI need to be able to control the throttle and monitor the speed, clutch pedal position and brake pedal position. I don't think it would be easy to add to an M49 mate.

Cars not built to have a BSI can't have one added either. Its a complex integrated second computer that acts as a master ECU for all things non injection related.

Thanks for the reply. 

I don't suppose there's anyway of telling if the ECU & BSI can do/handle all those things just from a visual inspection is there?

Any idea what a FBW throttle body might look like for a B9 1.6D, 2011, mainly the differences to look for,as I'm guessing most differences will be inside and I'll be looking for particular wires, or plugged holes for missing sensors.

Thanks for any help you can give

Ok so on the standard 1.6 HDi B9, the accelerator pedal is purely electronic (fbw), having 2 potentiometers inside that both go to the injection ECU. All B9s can in theory have cruise added, but on certain early years the cluster doesn't support it, so it will freak out when cruise is turned on. Normally on the ones that support it, they will display that cruise is engaged and the speed setpoint. But - it can be enabled on mostly all B9 HDi's using DiagBox.

There is no throttle body as such that you can remove, it's all under control of the ECU and BSI. (Diesels have no throttle body unlike petrols - early HDi motors had a butterfly thing called a doser but that's for egr gas mixing and anti-shudder on shut down. No longer used on later ones)

The ECU which Citroen call the injection calculator is reading the pedal position for normal "throttle" use, and setting injection pressure & duration as required, and when cruise is engaged, the BSI tells it what speed to go so it simulates the required pedal input to hold that speed no matter how the load changes for hills etc (up to a point - not infinite power of course)

The BSI is reading the cruise control stalk and monitoring the brake and clutch switches.

Hope this helps.

Yes it does help me a little bit thanks geez/geezette.

I know that the throttle pedal I need to have has a W, or V on it, sorry can't remember which at mo.

The above fact prompted me to think if any of the other parts needed had any special markings on their bodies or in the part numbers.
