Suggestion Needed: Fuel and Timing

Here's my working on fuel and timing map for my JDM VIII MR





Using TephraMod V7

Here's the setup:
Stock 8MR Motor
GSC S2
HKS Intake
Full Exhaust (TBE)
Cat-less
Blitz Dual SBC boost controller

Car is running around 22psi at this moment.
Fuel was E20

Please suggest me about the map.
Thank you very very much.

Regards,
Ohm

The maps seem alright but we can't help much without seeing a log.

You could probably go for some more cruise timing if you have the EGR disabled. Post up a log!

The logs are not exactly good, try doing some 3rd gear wots 2500 through red line, you seem to hit max load only once in one log file.
I didn't see AFR readings, I highly recommend that you get a wideband kit & log AFR before you attempt to tune the car.

I did a WOT run for many times and here's a log for that.
Still haven't got wideband installed but it should represent some data and idea right?
Anyone who has time and kindness please suggest me based on this datalog.

You haven't checked knock?!
You're logging too many unnecessary parameters, why don't you stick with the basic ones to start with: TPS, RPM, load1byte, timing, knock, & AFR. I still don't see the point of you doing anything before you get that wideband.
I think the timing is conservative for the boost you're running, you should get more power out of it if you tune fuel & timing. Don't do any thing before you get that WB kit.
I highly recommend that you read 'how to tune an evo' & the 'Merline Guide' as the are very useful to get you started.

Knocksum is there Foxbat, just that it's buried in the multitude of other parameters being logged...

As foxbat said, uncheck all the stuff you don't need. Not only does this de-clutter your log, more importantly it will give you a higher sample rate for each parameter that you actually do need. As it is now you're getting only ~3 lines per second whereas you need to be around 10 to have a decent log. Make sure you deactivate "log to screen" as well, as that also slows down the logger.

I will get wideband install in a few days. Now I'm studying Merlin's Guide and How to Tune an EVO thread.
Thanks a lot for the comment!!!!

looks like you are consistantly knocking at WOT TPS=100% and ~3100-4000 rpms right at cross over between engine vacuum and boost, load=100. Data is to scattered to tell much more. looks like your map could use some work. max injector dc is 89% so could use a pump or larger injectors for more power.
