I'm using a BMW M20 6 cylinder engine simular to MembersPage/GergelyLezsak
It uses the following sensors and injectors:
- 440CC injectors Bosch
- Stock single coil distributer
- VEMS Internal Map sensor (working)
- VEMS shop IAT sensor (working)
- WB02 5057 sensor (working)
- Other CLT sensor (working)
- Volvo TPS sensor (working)
- Stock VR sensor (working)

It's running better and better now. I actually drove a few times around the block. Primepulse is set to zero and all enrichments are still down to zero. I'm leaving for holiday soon so I won't have any time to work on the car the next 2 weeks. After the holiday I'll try to get the VE and ignition tabels and get the enrichments working.
Does someone have any pointers where to look at when I work on the maps? I have some basic knowledge but don't have any experience with setting up maps.
I also need to get my laptop working with the usb adapter cable. I'm still running into trouble but I've contacted my computer guy to solve this problem. Hopefully I'll tackle the problem before I get back.
Ps. Thanks for the comments Marcel. Keep them comming I'm learning a lot! So hopefully we can team up in the future to realise vapourised propane gas injection with VEMS.

The engine is started again and keep running!!!
Now it's just down to get it tuned.

My engine still seems to flood at only 2 ms. I really don't know what can cause this. Check my[config and tables]. But I've checked ALS and set all the enrichments to zero. Please help me out on this one. Engine fires at the priming pulse then dies and seems to be flooded.
- High Z 440cc injectors
Since you've got the car running, I presume this is resolved...
Well done on getting it going - it's the most difficult (and stressfull) bit.
The priming pulse happened when you first turned the key on, and the cranking pulse was what happend during starting. I have a 0.0ms prime pulse and the car runs fine. (When warm, idle pulsewidth is 1.35ms for a 5 litre v8 with 600cc highZ injectors.)
The "afterstart enrichment" parameter adds additional fuel to the warmup table enrichments (at the first few hundred cam revolutions).

Trying to figure out the primary triggger settings. This brings some questions along.
Tooth numbering starts at 0, with 0 being the first tooth after the missing ones.
- What is ment by the next trigger tooth? engine event spacing expressed in toothcount
- Next trigger tooth is how many trigger teeth between "events". So for a 6 cylinder,
- another_trigger_tooth=14 # = decimal 20 since 6 cyl has 3 events per crank rotation, so 60/3=20 (for a v8 with 36-1: 36/4=9) Note that this does not have to change if you change the "trigger tooth" parameter)
- What is ment by angular width to reset the enginefase? I don't have a cam sensor and it's a four-stroke 6 cilinder engine. So my firing order has to be reset after 720 degrees. Cilinder 1 at 0 degrees, Cil 5 at 120 degrees .......... Cilinder 4 at 600 degrees and Cil 1 again at 720 degrees.
- I think it doesn't matter even if you neglect it for now. Docs suggest decimal 240 for 60-2 wheel
- What is ment by angular width of tooth?
- 2
- What is ment by angular width of missing tooth?
- 6
Based on this my primary trigger settings in decimal should be:
- Rising
- Multitooth
- Disabled
- Disabled
- Disabled
- Disabled
- 56 (deg) TDC after the trigger
- Careful: This is the number of degrees after the trigger tooth as defined in the "trigger tooth" parameter.
- 58 Number of teeth on wheel
- 5 Trigger tooth
- 20 Next trigger tooth
- 2 Angular width of tooth
- 121 Tooth rel normal (Not relevant)
- 181 Tooth rel missing (Not relevant)
- 6 Angular width of missing tooth
- 240 engine fase, when to reset
I'll look at my notes tonight. I wrote a spreadsheet for my car that I can pass on to you if you need. That would be great!
