Re: Help please,HFS 4 V3 wiring diagram for E63 AMG
To save time, the next test will be with the engine idling. Same TPs.

When you do those tests, please ensure the red harness is unplugged so it can't fill your engine with water, just in case.

Re: Help please,HFS 4 V3 wiring diagram for E63 AMG
So far I have found one problem with the system. The system is seeing full IDC, most likely caused by the wrong configuration of the underside of the circuit board by someone, not from the factory. The controller seemed to be in good health.
Here are a few problem areas: 1. There should not be any solder links 2. "2" should be cut 3. All those the pads along the red line should be connected electrically

Re: Help please,HFS 4 V3 wiring diagram for E63 AMG
I don't have any idea for the 1st one and the 2snd one ,
We haven't changed them , please tell me how they must be ( if possible with a photo) ; We've soldered the 3th one , the wiring of G63 and CLS63 say that the thin cable must be cut and soldered to 2,5 . if you look at the wiring , you can see it. I read the instructions about Direct Injection system , it says like this : "The HFS-4 has three pre-set amplifications. x1 (default), x1.5 and x2.5. x2.5 will cover 95% of pulse duration systems of 0 to 5mS (common DI systems). . " |

Can you confirm if the E63 AMG is a direct fuel injection engine

Re: Help please,HFS 4 V3 wiring diagram for E63 AMG
1. This link is for some very odd fuel injection systems. But in any case, you must cut a link first before solder link another. You can clearly see the "C" is link and "B" is solder linked. Not a good idea.
Just remove the solder on B and you will go towards getting the system back to normal. 2. The links are for matching your MAP sensor. Again you must either cut the link"2" to Remove solder on "3". If your engine has a 3-bar map sensor, just cut the link "2" 3. Before going further, check there are continuity along the red line (normal). For direct injection engine, you are doing the right thing, link x2.5. What wire are you using on the grey connector? You should only use the thin red wire to the ignition switched 12V source. No other wires are necessary for the time being.
