Hey fellow Vems fan.
I am currently working with an R25DET engine that has the multitooth trigger system.
The triggers on the wheel have 2 circles. outser circle has 360 holes and the inner one has 6 holes for each cyl.
The optical triggers detect 120 degrees and 1 degree.
I have not finished the Vems yet so will do so asap to get some testing.
I dont have any clue about multitooth triggering so any help would be appreciated !
Q:
- Can Vems be used with orginal nissan multitooth trigger wheel?
- at least Fredrik Jagenheim (humming on ChatViaIrc, see MembersPage and look for Nissan with the search on HomePage) was experimenting with it, not sure about current status
- How different is MS files from Vems with MegaTune?
- the basic settings are very similar. However, files are not binary compatible.
How to change map sensor:
I have a 4.2 kPa map sensor and MT started up with an error like this:
I changed some data in the vemsv3.ini file:
Run MegaTune -> Basic setting -> MapRangeUnit = 4 (>510kPa )
-> Table kPa unit = 2 (high boost)
Locate and open Megatune2.25/mtCfg/vemsv3.ini
[MegaTune]
MTversion = 2.25 ; MegaTune itself; needs to match exec version.
versionInfo = "S" ; Put this in the title bar.
queryCommand = "Q" ; MSnS returns 30
- if 12X12
signature = "VEMS v1.0 12x12 kpa=2,2" <-- Change 2.2 to what ever you have.
Save'n exit.
Choose VEMS Genboard V3 12x12 High-Boost.
The settings in MT still shows red on the settings but atleast I get correct readings from my 4.2kpa map sensor.
