Can you post a regular data log as well? The composite log is just for checking RPM input problems.

yes I can and I have been trying to adjust a few more setting so here is an updated tune also

First, check the timing with a timing light while cranking.

Second, try adjusting the afterstart enrichment.

We have an in-depth article on startup tuning here: http://www.diyautotune.com/tech_article ... uning.html

From one 1JZ owner to another:

The stock 1jz wiring is over + 20 years old now, and full of noise. So if using stock wiring - at least replace the Cam and Crank sensor wire with shielded wire like DIY delivers in their wiring kits.
I'm running with no trim-pot adjustment (fully ccw), with no issues.

What coils are you running?
Stock (dumb) coils dont like more than 2,5ms of dwell. Anything over, and they just overheat.
If you need more spark power, go for a smart coil.

Ok thanks for the info i am not using the stock harness I took it all out and yes I'm ran shielded wire for my cam sensor crank sensor and knock sensors also I'm running lq9 coils also when you say fully ccw is that on all pots or just r52 and r56?

Correct.

R52+R56 (Mainboard) and R11+R32 (ms3x)
All fully CCW is working like a charm om my setup.

Ok that's but I guess I found some of my problems I found leaking injectors so as of right I'm upgrading to new injectors
