are you sure you're getting full throttle body movement

Hey, 

 

actually I am not that sure. I checked with Torque App and it only shows up to 80%, but the car feels how it should feel, and peugeot did not mention any TB-related problems.

 

I will check the throttle body as soon as my plugs arrives.

 

I made a little video to show you, maybe it helps.

Not completely pedal to the medal, just nearly getting closer to the rev limiter, than flooring it.

I would suggest you try a spare throttle body if you can

 

I would expect the ecu wont fuel for more than 80% throttle if you're only getting 80%

But would that alter the rev limit? 

 

I have no other GTi180 throttle body, but I'll give it a try and atleast figure out, how wide the butterfly opens.

sorry for the double post, but I just checked the TB and made a new short video and a few pictures, which I upload for further investigation.

 

I think the butterfly opens enough, but also have no idea why torque is reading only 80% - I try to get another GTi180 to read that out.

 

But, after a few seconds of google:

https://torque-bhp.com/wiki/Throttle_Position

 

I SEEMS to be normal. Clueless.

Drive by wire systems often have a strange reading on the throttle position. The system operates with a requested torque vs actual torque figure and opens the butterfly to suit.

 

Are there any faults registered in the ECU memory? And not just the ones that torque (environment related ones) can read, but also the intermittent faults. There must be something registered imho. It sounds like a limiter kicking in like you say. On modern ECU's there are lots of different limiters which operate on different parameters.

Hey, there was nothing stored in the ecu except "ac compressor not responding", because I deleted the ac System a year ago. I try to upload the logs from peugeot later this day.

If I was making a guess, it sounds more to me like a faulty crank sensor, or camshaft sync sensor than anything else. The crank angle sensor is near to the area that would be worked on when the clutch is changed.

The knock sensor is listening for a very specific frequency.

 

From memory, the way the throttle limiter feels when it is used for the stability program feels quite different to the ignition cut that occurs when you rev all the way to the red line (7300rpm).

The throttle limit is very drastic, and is like you have lifted the pedal. The red line bounces down and back up quickly.

 

Have you checked the plug on the crank sensor, that it's not coming apart, and is seated correctly?

Hello, 

 

sorry for the late respone! I changed the spark plugs yesterday, cleaned the crankshaft and camshaftsensors and found out, that my gearbox mount bracket was coming apart, so that was nice. The new plugs changed nothing and also cleaning the sensors was useless. Fixing the gearbox bracket also did not help. I have not tested to remove the knock sensor yet, because I cant imagine that this is the fault, but I will try that, after I changed a few parts with a working GTi180. There is one a few hundred kilometers away, with the same problem, but his seemed to be gone, after he had done a compression test.

 

I also got the protocol from peugeot and will write down the keyparts (the protocol is german, so I will translate it instead of just uploading it)

 

 

  •                     Engine speed     Voltage     Injection length    Overrun     Coolant temp
  • Idle:               736rpm             14.3V         3.120ms                no                87°C
  • Idle max:    7168rpm             14.3V         0 (cut off?)             no               82°C
  • 3. Gear:      7008rpm             14.3V         0                             no                91°C
  • 2. Gear:      6912rpm             14.3V         0                             no                87°C
  • Idle*:          6976rpm             14.3V         0                             no                96°C

 

*after testdrive

 

I will meet the other guy probably next weekend, but also got a friend near the nürburgring with the same car, who could lend me a few parts.

 

 

Thank you all very much

About EW10J4S and DriveByWire:

 

I´m planning to install AEM Infinity ECU to my car and I want to use DBW. Does anyone have a pinout for throttle pedal (from 206 GTI180) and TB unit?

If so, would be very pleased to have this info =)

Here is the pinout for the pedal supplied by Peugeot using service box. I have a Jenvey DBW motor and ITB's, so I didn't check the throttle body.

 

Unfortunately, I'm having trouble making it work (not with AEM, I've got Emtron KV8).

I think the output from the pedal must be a frequency or something. When I supply it 5V, the signal output is barely 0.2v change from 0-100%, and only on one signal side, the other doesn't change.

 

I'm considering using a GM LS engine pedal, as they are very common in Australia, on the Commodore.

Did your garage do any ecu update via Genuine Peugeot Planet 2000 or DiagBox? Peugeot lowered ECU limiter of EW10J4S engines to 6950 rpm for some countries with hot or dirty weather with new ECU softwares.

Hello, 

 

not as far as I know, but I will ask that. Next week should arrive a package with all engine sensors and ignitioncoil from another, working RC. I hope, that will help...

 

Thank you ALL very much. :)

Hello folks!

 

Minor Update to the situation. A friend sent me his coilpack, vvt switch and camshaft sensor. On the way to my shop, the car sort of repaired itself. It will now rev out in all gears except neutral (but no idea if thats a problem tbh) but now has a slight revhang and doesnt reacts to the throttle input as before. That means, when shift down and want to match the revs, it doesnt rev as well.

 

Switching out the vvt switch, camshaft sensor and coilpack had no effect what so ever. Over night I will disconnect the battery and relearn the throttle body tomorrow and change the watertemp sensor.

 

Still very thankful!

 

Chrissi

Sorry for double posting, but just remembered a user in a french forum told me to check the clutchpedal sensor... what should I say? I installed it correctly in its slot and now ALL problems are gone. 

 

Thats a reminder and I'll hope, it will help another user in the future.

 

 

All you guys well deserved my respect, just wanted to say thank you again (:
