Hi,

I looked at your datalog and I can see that you cannot go over 3500-4000 RPM because the MS2 is loosing the synchronisation of the engine. The 'lostsyncreason' parameter goes to 7 when the engine RPM is over 3500-4000. I do not know what a lostsyncreason #7 means, but this is normally a problem with you crank VR sensor, cam VR sensor, VR sensors wiring or VR circuitry in the MS2 itself.

Before doing anything else, we need to know what a lostsyncreason #7 is (start a new thread for it, I know someone have the lostsyncreason list, but I cannot find it now).

Another thing I saw in the datalog is that the accel is triggered again, even when you do not want it. This yield to a huge PW spike at idle. Verify that you set MAPdot Treshold at 255 and TPSdot Treshold at 255 too. This will disable the accel enrichment.

0 = no problem
1 = init error
2 = missing tooth at wrong time
3 = too many teeth before missing tooth (last)
4 = too few teeth before missing tooth (last)
5 = 1st tooth failed test
6 = nonsense input (last)
7 = nonsense input (mid)
8 = too many teeth before missing tooth (mid)
9 = too few teeth before missing tooth (mid)
10 = too many teeth before end of sequence
11 = too few teeth before second trigger
12 = too many sync errors
13 = dizzy wrong edge
14 = trigger return vane size
15 = EDIS
16 = EDIS
17 = didn't received the second trigger when expected in wheel mode

space for more common reasons
plus other special reasons for the custom wheels

33 = 6G72 - tooth 2 error
34 = 6G72 - tooth 4 error
35 = Weber-Marelli
36 = CAS 4/1
37 = 4G63
38 = 4G63

52 = 36-2-2-2 tooth 30 error
53 = rc51 semi error
54 = rc51 re-sync error tooth 6
55 = rc51 re-sync error tooth 16
56 = rc51 re-sync error tooth 18
57: Nissan CAS: wrong pattern, e.g. slot length increases but should decrease
58: Nissan CAS: longest slot test failed
..
67 = LS1 semi failed

maybe i need to put a cro on the vr sensors at 3500 rpm
maybe the vr conditioning circuit on the 2nd vr input doesnt like the surface mount chip (since the standard chip was not available from farnel)
i heard that reducing the 18k resister to 10k on the 2nd conditioning circuit may help
have tried 1.5k to 10k on the crank sensor but that didnt help

any other idea's?

Use the "sync error" composite tooth logger under "Diagnositics" start it saving. Then run the engine until it loses sync. Each time it loses sync it will record the tooth pattern that leads up to the lost sync event.

Stop saving.
Post the log here.

improved a bit with r56 adjust, (tried r52 adjust as well)now goes to 4000 rpm changed trigger but little difference, changed LC-1 sensor now getting better afr readings

what about changing cam sensor edge?
can lc-1 sensor be repaired or cleaned?
what about reducing 18k resister in 2nd vr conditioner to 10k?

have taken picture of video of oscilloscope reading at crank vr sensor input at rpm break down but not sure what it means
will try to post it here

maybe what it means is it is peaking in middle of 34 notches as well as normal, but how to fix is the question?

ive been busy with other details of life, it goes but not over 4k, and sometimes backfires at lower rpm's, idles around 1200 then drops down to 800 sometimes

So what is the correct trigger angle finally?

I'm using 575° and I'm dead on according to my timing light. Using the 36-2 crank trigger wheel and the crank trigger is at rising edge. The second trigger (cam) is at rising edge too.
