Default Re: Map sensor or lack of?

Sorry for the late reply Richard I had to buy a new multi meter my old analog one was not sensitive enough to read the voltage.
so the readings I am getting are:-
pre crank .036
idle .042

OK, there is no boost signal as expected. Can you probe the little blue wire (grey harness) at the engine side and see if you can read and voltage signal there.

I am unable to get to the wire that is plugged into the ECU but I can tell you when I was at the installers last week to have the wiring checked, there was power where the blue wire was tied in to the ECU (tie in point I believe), I don't know what the voltage was though.

As far as the controller is concern the blue wire is not wired to the MAP sensor. If you cannot check the blue wire connection then this diagnostic work is drawn to a close.

Try probing the gold tap on the RJ45 plug, you should be able to locate the tab where the blue wire is.

Who installed the system?

I took the car over to the installers today and have to drop it off on Monday and they will check the wiring again and make sure it is connected to the map sensor etc. I will let you know as soon as I know.

cheers
Andrew

one more question for your Richard if you don't mind.
Before I hopefully get everything working properly next week the only way I can get the system to run right at the moment is in single stage mode. Is the threshold trimmer the only thing that effects single stage mode? so as soon as the threshold trigger is hit it just sprays at 100%
I assume thats the case but just wanted to make sure.

Cheers
Andrew

Have you tried to run 100% IDC only?

- THRES: 10am
- P/I-R: 4pm
- GAIN: 12 pm

Jumper link:
- TRIP: IDC
-MODE: PWM

Let me know

I am running of 100% IDC (TRIP: IDC) at the moment but set to SSG. I have tried virtually every setting there is to try.
I will give the settings you suggest a try and let you know how it goes.

Cheers
Andrew

I really think there is a wiring issue, I have never encountered these issues. Unless of course the controller is damaged.

Can you take a super -hi res picture of your controller, both top and bottom and post it to richard at aquamist.co,uk, I like to examining it closely.


Meanwhile can you take a few more readings on the test points for me?

Sure I will take a picture of the board. What test points do you want me to test?
