Summary of change:
Hey fellow Vems fan. <code> I am currently working with an R25DET engine that has the multitooth trigger system. The triggers on the wheel have 2 circles. outer circle has 360 holes and the inner one has 6 holes, one for each cyl. </code> The optical triggers detect 120 degrees and 1 degree. <code> I dont have any clue about multitooth triggering so any help would be appreciated ! </code> http://i40.photobucket.com/albums/e221/joika/P4040754.jpg '''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''': <code> I have a 4.2 kPa map sensor and MT started up with an error like this: </code> http://i40.photobucket.com/albums/e221/joika/errror01-1.jpg <code> I changed some data in the vemsv3.ini file that seemed to help </code> <code> Run MegaTune -> Basic setting -> MapRangeUnit = 4 (>510kPa ) -> Table kPa unit = 2 (high boost) </code> Locate and open ''' Megatune2.25/mtCfg/vemsv3.ini ''' <code> [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 #if HIGHBOOST signature = "VEMS v1.0 12x12 kpa=2,2" </code> <-- '''Change 2.2 to what ever you have.''' <code> Save'n exit. </code> <code> Choose VEMS Genboard V3 12x12 High-Boost. </code> <code> The settings in MT still shows red on the settings but atleast I get correct readings from my 4.2kpa map sensor. </code>
