bad rmp

[Arthur]

I'm lost

(60-2 4cyl wasted spark)  Setting trigger to 120degr and tooths to 0 and 30 works nice. Setting it to 60 and tooths 10 and 40 does't. I checked the 120degr with scope and all advance at 0 and it't spot on. If I try With 60-10-40 the rpm reading is bad. It changes from eg 2600 to 1300 a few times an second. Looks like freq is wrong or something.  I tried 60 with tooth 10 and 30 once by mistake. It runs bad on 2 cyl then offcorse bud rpm reading looks good. Does using 120 and tooths 0-30 hurt the ecu?

It wont hurt the ECU, as long as your timing remains stable things should be okay.  What engine is it and where did you get the config for it from?

I use the 1.0.73 packidge off an callibra you linked me. It's a peugeot 1.4xsi tu engine (Turbod). The settings I'm on are all mine. I couldn't find any usefull other similar engine builds.

I'm re-reading what you've written.
The second trigger tooth is relative to the first - so setting it to 40 is going to be wrong, it should always be 30.  So if you're getting 120 with trigger tooth 0 at 0, if you set trigger:
tooth 0 to 1 should mean TDC value of 114
tooth 0 to 2 should mean TDC value of 108

O oke

I didn't know the next trigger was relevant to the first. thats why 60-0-40 gives bad rpm.
