This project is in a weird state. Do not experiment without a concept (the most likely outcome is wasted time and perhaps damage.

Do not experiment with known trashed config. It does not make sense.

Pointing to a wiring that apparently does not even match the connector type => unlikely that it could work this way.


History

I purchased a 2nd hand home-assembled PnP? VEMS v3.3 and have installed it on my Mk1 VW Golf 2.0 ABF 16v Turbo. The former owner has written a lot of info about the assembly here:

MembersPage/BasilDaham/CordobaSX

  • THANKS FOR THE UPDATE - MUCH APPRECIATED: You're right, PnP? is the wrong term, it is an adapter harness where the original harness's multiplug pinouts have been used and then run to the EC36 and 18 connectors.
  • in any case, watch the ground rules, easy to get wrong with a homebuilt PNP device. Thanks - all grounds checked for consistency and are fine.

The v3 #671 mainboard was replaced after damage, to brand new #1746. Hopefully the new is not killed yet. Appears to be perfect.

It would be best to write your own pages. Fine to start by copying parts from Basil (0 time), but make sure to only include the wires that you really have, and verified, preferrably end-2-end from engine connector to ECU connector. Including the flyback and the 5 ground wires!

You can update your own page any time (you understandably don't change Basil's), and to get things sorted instead of getting them tangled more and more.


  • UPDATE 2/July/2008

Rob from VEMS UK sent me a known good config, which can be viewed here:

http://www.vems.co.uk/VEMSInstalls/VemsMT1.0.73.60-2.zip

The crank signal is now perfect and everything else appears ok

The car runs wastespark Bosch VW coil (exact type or photo maybe?) with the factory ignitors removed.

The coil is identifiable in this picture:

mk139.jpg

It is used on all Golf 4s as far as I am aware.

This is the complete engine:

Checklist - unlikely to be a problem though

Only after you stop experimenting with known trashed config. First upload a known good config and check these if you still have a problem.

  • I don't have a copy of the original config as I never generated it when the VEMS first arrived

When we first installed the computer, the car ran ok, but with a weak spark. After a few starts, the crank signal started to become intermittent: it would appear and then disappear and the car would run and then fail to run without the signal.

Would be typical with insufficient grounding, but we know little about wiring so hard to tell.

Eventually, the RPM signal disappeared entirely and "trigger errors" showed up on Megatune.

Since this point, the RPM signal has become intermittent again:

- It jumps to 250rpm under cranking and back to 0rpm all the time: signal, no signal, signal, no signal

not surprising: if suitable config not uploaded

To untangle this, subsystems should be moved (deleted from this page) to their own subpages. Only leave uptodate info there. If writing any info that is old (eg. config dump read BEFORE the most recent firmware upgrade) :

Are you absolutely sure you uploaded this config and tables ? It sounds like you uploaded firmware without uploading config + tables.

That means the above mcd/mct might not be what you have in. You can download, verify again.

Or you can just do what should have been essential in the first place, and upload your known good config.


If still no success

publish details about your setup (see IssueReports for checklist )
