Primary trigger pullup
I removed the R30 but now engine is totaly dead,no spark,no RPM readings in MegaTune...
Why do you remove R30 ? A 10..22k pullup on VR trigger input makes it more tolerant to trigger noise.
- Important: measured DC voltage on trigger input ?
- with R30=18k pullup, should be around 516 * 5000/(18000+516) = 139 mV
Secondary trigger
- not used (?)
- secondary_trigger=02
Trigger problem - reverse polarity VR ?
Make sure to include sufficient info, see IssueReports
- firmware version
- mcd, mct dump

While cranking, I got trigger errors in MegaTune
- I replaced the sensor and did better groundings on VR,still the same
While cranking before getting trigger errors rpms goes up to 740 and for a second to 0 and back up to 740,it looks like engine wants to start but for some reason it loses every signal for a second and then back on.
Using stock missing tooth 60-2 with stock VR

- looks reverse-polarity:\nÿ1ÿ
The left side has the meaningful data. It seems you get 2 longer gaps (3234+ 2216=5450 that is 4*1363) instead of a proper almost 3x long (around 1400*3 = 4200 would be proper).
Your VR sensor seems to be polarity-reversed.
