Hi,
Im trying to find out what the relevant wires are on the bosch throttle body found on the Focus ST/RS, and C30 2.5turbo models part number 30711552. So far ive found the following.
1 -
2 - ground
3 - +5v
4 -
5 -
6 -
There should be. Motor +, Motor -, Butterfly Sensor 1, Butterfly Sensor 2
If anyone can help that would be much appreciated.
Regards
Martin
Well well well... I was only asking about this project.... About 2 years ago lol. No idea what wires you need mate but it's nice to see the project ongoing
There's a marked up diagram although a different engine, may be some use http://www.swededemon.com/images/SD7/shots/ecu/schema-1-signal.jpg
Hope this helps... Going on the second image with the ecu pins, info for a B5354T7 2009 model with a 30711552 throttle body: [TABLE] [TR] [TH]TB Pin[/TH] [TH]Control module terminal[/TH] [TH]Signal type[/TH] [TH]Ignition on[/TH] [TH]Idle[/TH] [TH]Miscellaneous[/TH] [/TR] [TR] [TD]1[/TD] [TD]A75[/TD] [TD]Throttle unit motor, control signal (-)[/TD] [TD]-[/TD] [TD]PWM signal U top=Ubat Pulse ratio 0-100%.

That's a great help thanks very much, where did you find that information?
I know the project has taken longer than anticipated, things get in the way, and I don't know where the time goes, but it's all done, just finishing off a few bits on the engine loom. It's turns over and everything.
[QUOTE=surrey_100e;789134]That's a great help thanks very much, where did you find that information?[/QUOTE] Info is from a Volvo tech document. Lovely project, I like the attention to detail throughout the whole car, everything looks so clean :)
