Lost RPM + on Megatune only getting 4.82v

[Will]

Ok mate thanks, will give it ago after work later this afternoon.

Hope I can get the stupid thing to run soon!

[Will]

Made bit of progress it seems like?

Change the Angular width to 3 instead of the 10 it was. - Nothing
Changed the wires around. - Nothing
Had another look at those primary trigger settings and saw next trigger tooth was set to 18, I changed it to 1 like the trigger tooth setting is. I now have an RPM displayed but when cranking its around 1000 instead of the normal 2-300 RPM.

Do i have the devider that works out the RPM incorrect?

I didn't test for sparks as my battery was dying so didn't get chance.

It does sound like the trigger settings are buggered.
Can you post a screen shot of your primary trigger settings please?

Next trigger should be 18 - as its a 36 tooth 4 cylinder a trigger comes along every 18 teeth.
If any of the filtering is turned on then there's problems.

Will - can you a) Download your configs and tables, b) give me the serial number of the unit.

I finally got my dead PC back and running (as a Virtual Machine) and should be able to compare your trigger config with a known good one.

Where are you based mate?

The serial number is 1304.

I posted a copy of the msq file and the previous page to this post.
The only difference now is that I changed to tooth angle to 3deg and changed next trigger tooth to 1 from the 18 it was set at.

Will do another download of it with screen shots tomorrow before work.

I live in Stoke-On-Trent, Staffordshire infact about 5mins away from Paz.

I need the config and tables to work with mate.  I've never been a fan of msqs
The download method is written here:

Here is my tables file as well.

I've been through the trigger settings, and the only differences I can see are
Your config's trigger section:
primary_trigger=01
secondary_trigger=00
tooth_wheel=23
trigger_tooth=01
another_trigger_tooth=12
crank_minper=50
tooth_wheel_twidth1=03
tooth_wheel_twidth2=06
cam_sync_r_edge_phase=FF
cam_sync_f_edge_phase=FF
reset_engphase_after=D8

Known good config trigger section:
primary_trigger=01
secondary_trigger=02
tooth_wheel=23
trigger_tooth=01
another_trigger_tooth=12
crank_minper=50
tooth_wheel_twidth1=0A
tooth_wheel_twidth2=06
cam_sync_r_edge_phase=FF
cam_sync_f_edge_phase=FF
reset_engphase_after=D8

The known good one has the secondary trigger set to 02 disabled, yours is set to 00, which might be the issue.
The other issue is that the tooth wheel twidth is 03 which you changed from 10.

[Sprocket]

Rob, here is the config I used with 1.0.73 with a 36-1 trigger.

primary_trigger=11
secondary_trigger=02
tooth_wheel=23
trigger_tooth=01
another_trigger_tooth=12
crank_minper=30
tooth_wheel_twidth1=03
tooth_wheel_twidth2=06
cam_sync_r_edge_phase=01
cam_sync_f_edge_phase=02
reset_engphase_after=F0

Remember that the tooth width is a scaled value, and there is a calculator to calculate these vlues, linked to from here http://www.vems.hu/wiki/index.php?page=MembersPage%2FPhatBob%2FUserGuide

secondary_trigger=02

Needs to be 00 otherwise the ecu will look for another trigger input and if that never shows. Nothing really usable happens.
So OP should now be able to get some meaningfull rpm´s if he changes to 2 in vemstune

I was always lead to belive secondary trigger needs to be set to 02 to dissable, it says so in The megatune config window. 2 decimal is 02 hex? no?

[gunni]

I´m wrong of course..

What I meant to say was that his config suggests that the ecu is waiting for a second trigger that never comes.

Still getting nothing 

Only was I can get a rpm signal is if I change trigger tpye to coil. But then it's an eratic reading.

Going to see if I can find some wire to make a lead to the sensor, allthough I'm getting good continuity.
If not will try a new VR sensor.
