Excellent news about the "happiness" with the tune, I know the entire forum is proud for you, you've got one hell of a car there.
Thanks Hornstar appreciate the compliment
I monitered the egt gauge very closley while leaning out the fuel. Its still a little rich since If I floor it in 3rd at about 2200 rpms and hold till redline I drop down to about 11.0-11.2 then by about 3000 I will be at 11.4 and it will hold 11.4-11.3 all the way to 4500-5000 then taper down to about 11.0 by redline. Even doing a 4th gear pull al the way up my egt's stay at about 1600 which isnt bad at all.
town cruising=1100
highway cruise=1300
WOT full on getting on it=1600

Thats good man. Im scaling the MAF, for me it seems the only way to get "rich" and its not easy. Its difficult to keep AFR predictable and steady but im getting there, so far from 3800- redline im getting 11.2-11.6 but from like 2,700 - 3,800 its like 12.3- 14.5....its really tough but im getting closer! Glad to see the progress your making!

Also whats the peak timing your running during boost? i cant seem to get any higher than 2 for some reason withought getting knock, not sure if its because the fuel isnt consistant or what, im sure it has something to do with it, but it knocks sometimes then it pulls timing to 0 or -1.

I think fuel really influenced knock on our engines more so than others I think its more suseptical to knock the further away u are on fuel. I can run 2 degrees at 4000-4500 wot with usually no knock but some runs I will get 3-4 counts randomly so I don't bother with it. I really think the correct knock settings using the tephra ROM are somewhere in the middle. Although I don't recommend changing without extreme caution and close monitering. My car pulls so hard I love it

Yeah, after 3k my car PULLS very nicely, but, it suffers on accel. Its hard cuz its an auto, but i feel like i could have accel'd harder and faster withought the turbo on right now When i try to advance the timing a couple degrees for a better accel, the car knocks, im not sure if its timing, or the knock sensor, so i guess i have some work to do! How long have you been running 12 LBS?

Just recently with the 12 ibs. Maybe a month or two at most. The car just loves it though. Flat gets on it compared to my stock form for sure. I really wanna log a stock lancer now though and check some things out to compare like Any knock spikes at different loads and what not.

Thats aweosme man. Im havin so much fun just with 5! Well sometimes when i go WOT from idle, it spikes to 6-7 and tapers off to 5.5 or so, i think with christmas comin up im going to get some head studs and maybe a "tougher" head gasket. I should have taken a log of how the car "knocked" and ran stock, without any mods or anything before i proceeded to flash the car with my own settings and the tephra rom, but i was too excited haha.

A friend at work just bought an 03 oz with about 130k miles, no mods. I can go driving with him and log if you want....if it'll help.

So we want some WOT, and what else? Would turning the stock knock sensor threshold down to 0 and logging some be at all helpful? I don't know if he'll let me, and even more important, I don't want to betray his trust in me by breaking something on his car. Perhaps just some WOT to start with, and we'll see how it lines up with the knock numbers in a turbo'd car.

yeah man i wouldnt do anything with the knock sensor especially if its your buddys car and dont wanna mess **** up by accident. take some WOT pulls, take some normal accel logs as well, i want to compare the timing to mine every now and then i get knock below 2,000 rpm, not sure if it has to do with my timing or if its the knock sensor freakin out

That would be sweet man!! I have logs of my car stock WOT in third. Get some also of gradual throttle increase all the way up to redline if you can like make it Wot close to the end. Seems like I always get more knock just easing into boost and only having like 1/2 throttle while in boost although my afrs are ok. I seen counts of 14 in my stock car WOT. 87 octane though.

Hey I went through my logs and found my pre-turbo logs.... man are they screwy lol. Some I dont even log tps OR rpm. Others I log this then logged loadcalc giving me loads of 213!!! Others still I logged rpms and tps but not knocksum??? What the hell was I thinking lol.

Anyways on topic. So I noticed an interesting thing my LTFT's seemed like more times were outside of the +/-5% range than in and I seen as high as 10% at times. I did not have a WB at that time but I did log AFRMAP in some pulls and seen it drop down too around 11.5 in that. Looks like I seens Airflowhz coming in at a high of 950, not sure if thats correct or not though. Seen my timing dip down as low as 3 degrees with no knock?? Dunno what that was about.

It seems like a trend even with the stock lancer with no mods at all like when it does knock its in the 2500-3500 range.

All in all my stock logs suck lol. Hornstar maybe just log a bunch of stuff and put the car through as many scenarios with load and rpm as you can. Sample rate wont really be an issue since its not for tuning the car just to give us a snapshot of stock running.

headstuds are a good idea, but stick to a Mitsubishi MLS gasket and nothing but that(dont see my receipt, but 80ish$ from dealership, maybe 56.. i donno both numbers sound familiar), they are much more forgiving with boost then decompression gaskets or thicker copper gaskets.
but realistically, Id say just hold off on everything, get some pistons and rods and do it all at once.. If u break or bend a rod, a new motor will set u back about 300, not a big deal, but then u have to get new headstuds and headgasket and start all over. i had tons of parts just sitting at my house just waiting to get installed untill i had all the pieces needed.
If ur never planning on running more then 9psi, then dont worri about building it, u should be fine till the piston rings go bad, headstuds arent even needed.

Yeah, I did a few screwy logs as well, until I learned what helps and what doesn't.

Enzo and I are talking about logging some tomorrow. I'll do some low rpm wot all the way up, and try to go into WOT at each rpm range up from there as well as some downshift and pass type stuff too. So, the sort of stuff I typically really care about in logs is:

RPM, TPS, load, airflow, IDC, AFR if available, o2 feedback, timing, knocksum, and sometimes fuel trims cause why not...

Log knock voltage too this might help us with good indication of real knock vs fake knock. I know your not supposed to use voltage alone and I dont without hard evidence to back it up but we migt see a pattern in there somewhere... Also speed and if you feel like airtemp you could throw that in if you wish. I look forward to seeing the results
