Your spoolup timing looks a bit low to me, and your peak boost timing looks a bit high. You are hitting peak load late for a 2.3L w/fp green. there is more power left in there.

Well it was 8* for some time when I switched from stock turbo, that was really too much )) That produced some more torque, but was knocking pretty often. 5-6* seems to be optimal for street use now, as it produces not much less torque than 8* but never knocks. May be I would drop 2 more degrees from the whole map if I go to the track or if the gas become worse.

Anyway I think I should pay some more attention to the high rpm spool up areas. Flooring the pedal from 4,5-5K sometimes, rarely, inconsistently makes my CEL flash slowly(knocksum 3-4).

What octane fuel are you on for this map? are you running 25 psi peak boost?

Biggy VIII

I run Ron98, thats something similar to 93octane in US, but doesn't contain so much ethanol and more knock prone.
I am shooting for 25 psi peak tapering to 22-ish at redline, but sometimes it overboost up to 26-27 at peak torque.

Biggy VIII

Its 8, so no mivec, and it's not a 4rth gear dyno pull. You still think peak load at 3,5-3,7K is late for a real road 3rd gear run log?
Peak load 270-280 at 3250 @ 4rth gear.

A bit higher spoolup timing makes it knock time to time.

to be honest, im not as familiar with the VIII, but it doesn't seem right to me that it can only take 5* at 200 load and it can still take the same 5* at 300 load. You say that you get knock on spoolup with more timing than you have... could it be phantom knock? is something rattling? i.e. downpipe rattling crossbars or something?
I have a IX on crappy CA 91oct that has 5* at 200 load and 1-2* at peak boost (24psi). The IX's use lower timing than VIII, so it seems like your 93oct evo viii should be able to take more on spoolup.

Biggy VIII

I believe it may be some phantom knock(2-4) as it was not constant, but I decided to drop down a couple degrees on spoolup from 140load to be more confident in my tune and it helped a bit and almost fully eliminated it.

Evo9 has mivec and I bet you have 28,8 in your map at peak boost. It seems to me thats about 4* more advanced cam comparing to evo8 cams installed straight up. If I advance my cams so much, it should spool faster, gain some low end torque and I will be able to run only 2-3* timing knock-free.

Actually I had an idea to venture a mivec swap...

I would smoothen up the middle of the map. the 100-140 areas timing is dropping WAY too quick.

Your peak torque timing is a bit on the high side.

Here's mine. This is on my 2.3. Feedback and suggestions are welcome.

This needs work. Your cruise timing is way too low along with your Peak Tq timing.

Biggy VIII

Could you please post a log or at least tell us what load at what rpm are you hitting. What turbo and what octane are you running.

Peak torque is at 4200 rpms in the 200-220 load cells. Turbo is the 5858 and in on 93.

WOT timing seems nice.
Spool timing drop faster than usual, but it's because you hit 220load with a 2,3L PTE5858 at peak load. This points to me that you're on SD right? It's like if VE maps would be set too low. With that setup, you should be hitting over 300 load, even on mild boost. This would give you more map resolution for tuning.

At cruise (2.5@3.5kRPM) the total timing (EGR advance + high oct timing map) should be between 40 and 45*. You are under 30*, this thing must feel pretty heavy (bye bye mpg).

I've never thought of it as feeling heavy, but I'll make the following changes and see how it feels.

Still a little soft, take the OEM VIII timing map and start from there, no need to run less than OEM cruise timing. You actually can raise EGR enabled advance to easily save fuel.
And a little hint, 0-10-20 load timing can use a little bit less timing because it help smoothing the transition from throttle on to throttle off.

Here is my latest timing map, pretty agressive on cruise (38*map + 5* EGR), but no knock and nice MPG.

SD tuned, Hitting 270 load @ 3250, to 250 at 7400. Not much taper because I run flat 24psi (modded stock catback but still restrictive ; 3" CBE in fabrication right now)
