Hi,
Found the problem. There was no continuity between DET3 ground and DET3 USB connector shield.
I used a bridge wire to solve the problem.
Tested for about 20 min at different loads and it worked. DET3 stayed connected the whole time.

Keep you posted.
Thanks for the help!

OK i will first thing in the morning.

One more thing. Shouldn't it disconnect also if the ignition system is faulty when the revs go to redline under no boost? Because as I said it disconnects mostly when under boost.

An update.
It's not disconnecting if I don't go in full boost (load) up until red line. With or without the MAP sensor connected.

I have connected the VR sensor as per attached with shielded wires. The VR sensor is grounded to a different location from the DET3.



P.S> Should I ground the shielding also?

P.S.2. The sparkplugs are NGK BKR7E resistor type they're like new.

Hi It's a Mercedes w202 m111 engine. All ignition wires are ok and covered in the engine. Before DET3 I was using SMT6 and had no problems at all. DET3 is disconnecting randomly from the PC. One time is while the engine is idling and the other time is when under high load. If just cruising around wi...

Hello,

We have tested several PC's and all of them are randomly being disconnected from DET3.
I also tested several USB cabels.
Do you have any suggestions on how to solve this issue?

Thanks in advance
