P1000
Not sure but like you say it has to run x amount of cyles

Yes there is a frequency difference between the Vss sensors. I was going to look at a speedo healer often used in Bec installs.
Again after driving it I can’t tell any differance.

Well, i dont know if the ECU completes the Adaption process where it "learns" all the MAF adaptions, idle values and so on.
Did you ever look if the ecu has completed the adaption? My Thoughts are that the ecu must have differenct vehicle speeds where it does the adaption
process, maybe i am wrong? Did your P1000 ever disappear?
I fitted now a Aftercat O2 sensor, i will try if it the p1000 disappears with the "Abtriebswellen Sensorsignal fehlerhaft" (Dont know the
english words for it) But when VSS is disconnected, this error appears.
For me this are the only 2 P-Codes in my ecu.
Which one do you have?
The weather here wasnt good enought to make a big test drive to check it out.

Just to say a big thanks to big_wasa for all this info!!
Got our ST170 up and running first try!

Thanks for the feed back. It encourages me to do others.

Hello,
i have another importend thing to know for you.
I have fitted the ST170 generator, und i have connected it to the ECU, so ecu controls generator.
The Generator has 3 Pins: 1 +12V 2 goes to ECU.
I have connected the 12V to switched live, but this is a big mistake!
You must connect the +12V for the Generator to permanent live, otherwise it will drain your battery very fast.
I drained my new Banner 30Ah Battery in only one night.
Just wanted to warn you !
In st170 focus it is also connected to permanent live, but i thought i am smarter and switched it off via ignition.
If you have not connected the plug, the generator will load the battery but i think the voltage isn´t controlled so exactly.
Also if the plug is not connected the generator does not drain the battery, only if connected wrong.
Hope this helps someone.

hi, thanks for the many useful informations.
i got an st170 to play with. i dont have the original harness or another focus to check how it was... so how can be sure my vvt solenoid still
work?
as i understand from the list of the pins:
>>45 black/red—vvt solenoid pin 2.
i can apply a 12v on pin 2 (ok, ecu will control it with pwm but for see it still work should be enough)
i'm correct? im afraid to damage it.
thanks,
David

Its just a solenoid so its switch 12v supply and the ecu switches the earth pwm.
As long as your 12v supply is fused you should be fine if I understand what your asking.

The ecu nearly always switches the earth.

This is the injectors but its the same principle.

yes, i got the idea.
i did a quick test, there is continuity but doesnt move.
i will retry after work, thank you again.

Hi guys!
I hope you're well !
My ST 170 run's well since 2 years now ...but I have a problem with the IMRC
I 'll open the box this week end but I think it's broken
So, I 've a question: were can I find an IMRC . Can you give me a website adress ?
Thank's for your reply
Jean

They are fitted to the 2.5 v6 Mondeo as well. There are also guides on YouTube on how to fix them.

Hi, I have a project and been following this thread.
Now I have managed to get it going using startgas, but no fuel comes through the injectors.
I have mounted the fuel rail pressure sensor, but on the connection list on the first page only replies to one of the three wires.
Nr 1 on the sensor to 37 on the ECU.
My question would be where are they supposed to go? Are there any other reason why the injectors don`t open?
Thanks for a very good forum, I would not have come this far without it.
Regards from Norway Johnny B

Hi, it’s a long time since I looked at this project.
The ecu pin out is just that each sensor / actuator will have other wiring requirements.
The fuel rail pressure sensor has three wires.
Yellow is 5v supplied by the ecu. You just T into it.
Brown is sensor common again supplied by the ecu and you just T into that.
White being the sense wire to the Esc.
Cheers

As to why the injectors arnt firing, it’s hard to say with out getting hands on.
First question is always is the Immobilizer doing what it should as this will Immobilize the injectors and other things but not the ignition I am told
by the banger racers.
Have you put a code reader on it to see data of what it is or isn’t doing ?

Thanks for reply.
I thought that as the sparks ignite, the immobilizer was doing its thing. I will have to check how its flashing and lightning one more time.
Somewhere earlier in this thread i read that it wouldnt start whitout the O2 sensors at the exhaust, could that be an issue?
I havent got those 2 sensors.
Is there a better way of running these engines, whitout spending 1000 pounds on parts and dyno testing?
Regards Johnny B

It will start and run with out O2 sensors. It won’t run properly, efficiently.
To run it effectively you need to run it as ford intended. Ie full fuel injection with closed loop fuel control with a cat.

In your profile it says Mondeo race car. In the Uk for stock car, banger racing you would not use fuel injection and this ecu is way over complicated
to use just for ignition.
If you are running the fuel injection it is a viable option on a budget. But you will be lucky to make what a blacktop does with out using everything.
The st170 is well known for not making anything like 170bhp unless everything is tip top.

Hey guys !
I hope you’re well,
I have a question for you
In 2020 I install the Zetec 170st in the car and it works quite well: I ‘ve follow the excel table and it was ok, BUT!
For a while, the engine sometimes cuts out when exiting a turn, especially on left turns.
Then It blows a fuse (sometimes)
The tank was build like in the book with a partition wall , stilling tank and foam for gasoline
My question: did somebody had the same problem and what to do?
(I shecked the wiring, it looks ok)
thanks for your reply!
