Forget essays. Make subsection, or even subpage of each subsystem. Don't let subsystems mix, and . Find at least 4 installs from MembersPage that are split to min. 5..6 pages. Read them.

- This daewoo engine might be very similar to your (opel?) engine, but beware to use tables that have
- h[2]=02 03 02 03 .. .. .. ..
- that matches you ignition wiring. (because the 1.1.x requires different h[2] )
- also check h[0] to match your injector output setup
primairy trigger i'm using a VR sensor with a 60-2 tooth wheel. It's an Opel C20NE engine. The VR+ is connected to EC36pin27. IAT,TPS,CLT is responding nicely. Only need some minor calibration maybe. I use a passive wasted spark coil. That is connected to EC36pin34 and EC36pin36. Can someone help me in the right direction?
MembersPage/PhatBob You need to use a timing light to check the spark timing is showing the correct adavance (which is determined by the cranking advance setting). Make sure that there is no power going to the injectors so that the engine doesnt flood.
I don't have a timing light yet. Is it still possible to start my engine. I just wanna know right now. If I build something that actually runs/idles.
Have a read of this: http://vems.hu/www.vems.co.uk/VEMSLoom/LoomGuideUnitNNN.doc
As it covers the starting proceedure
Cannot read the .doc file (tried MS Office and OpenOffice)

I'm gonna try to put some information on this page. To help others understand what I have connected to VEMS. And how it is connected.

To keep this page clean I will put all my questions inside a table. Please put you answer inside a row. So it's easy to find an answer to a particular question.
The key to clean page is not the table format. Actually, bullet format is better for questions. When you post a question about your fuelpump, you WANT TO
- DO IT IN A SECTION THAT DEALS WITH YOUR FUELPUMP. Forget the collection of questions in one place.
- tell everything you know about your fuelpump - eg. fuelpump+ switched by a 30A relay, the relay solenoid- controlled by EC36pin...
With questions of enough detail it is possible to give good answers.
Otherwise you'll likely get answers like "follow the manual".

| What firmware to use? | |
| Where to get some basic config.txt and tables.txt to start with? | |
| How do I configure my 60-2 trigger wheel? | |
| How to set all my inputs and outputs right inside config.txt | |
| Can someone make a base config for me? | |
| Is there enough information on my MemberPage to make a config.txt? |
- My engine code is C20NE. It is similair to C20XE and C20LET. Some people run it with VEMS. Can I use their config.txt?
- You should describe your engine. Really. Don't expect others to know your numbers.
- How to test if VEMS can activate my fuelpump?
- disable the fuelpump in config (eg. MegaTune) and issue mdh.. according to GenBoard/Manual/DigitalOut, GenBoard/Manual/DigitalOut/Table . Eg. if fuelpump relay controlled by EC36pin6 =Inj G than have
- h[0]=.. .. .. .. .. .. 40 .. (which is the entry 6 from the 0..7, and is written as decimal 64 if viewed in MegaTune)
- and mdhe0, mdh60 will turn your pump on and off.

- Can I test injectors before trying to start my engine?
- yes, you can. Well:
- If you think about injector outputs, you should
- if you think about injector wiring, you should
- if you think about injectors (which I doubt), than no. Injector flowing bench is out of the reach of most installers
