Yes it can lead to higher EGT if timing is too retarded

 

+1 egt temps will rise because less heat is being used up creating power and instead gets expelled out the exhaust .

 

Well freakin good call then. I pumped the ignition timing up a bit, especially the spots where it felt like it was having trouble getting power....I'm betting I'm waaay retarded in a few spots.

So, EGT's were lower this drive around, and I'm also betting that my screwy timing hurt my mpgs too. I got 28mpg last tank, but I was on track to do 31 or so. I wonder if in the lower rpm spots where I see a few knock counts...I wonder if I don't have enough timing, is that possible? I guess I'll pull the proper amount, and see if it goes away, and if it doesn't, I'll add a smidge just for fun.

Oh, also, wow...like many have said, I guess I just didn't expect such a large disparity, I hit 100 load without even pushing the pedal down, basically boost starts at 90 now...give or take a few load, so I'm increasing timing a bit in those area to see if it shows any knock, because I bet the more I increase it to about where it's supposed to be, the cooler that exhaust will get....within reason.

I know the throttle cable was fine until I put the evo rom on, so you guys are probably spot on...not that I doubted you. Ofcourse, I really got on it a little more with the base lancer rom, and it wasn't near as hot. Still a little worried about the knock sensor, just because I'm not sure if all the filter maps that were in the base lancer match what's in the evo rom....but, meh, at this point I know I'm way low, so I'll just bump it a little. I definetly do see knock, when I'm on it a bit, like the 90+ load stuff....so it's working, I'm sure. I got probably 3 counts on the 2 more aggressive pulls earlier, so I'll pull there, but increase a bit lower than that.

 

So, below is a pic of my timing and my knock counts. I've got all the thresholds set to 0, so I see everything. I've increased and decreased timing in those low RPM areas, and it doesn't seem to make much difference. There are plenty of zero counts of knock in those areas, but randomly there will be 1 or 7 counts. The one thing that still concerns me, keeping me from upping the thresholds back to what I had them at. This one thing is that I seem to only see the knock counts when going slightly uphill...but plenty of times I go uphill and don't see them.

So, perhaps I just don't know how to drive a stick properly, and ought to just put it up a gear when I'm going uphill and less than 3000 RPM, aye?

About those upper RPM though, my timing is about...7-10 degrees less than 03lances map, and a few less than some of the others I've seen as well. Should I increase timing as I go, or only at WOT, because that's more reproducible? Like, am I pissing up a rope if I try and get timing "maximized" throughout the entire map?

Just FYI, that highest load stuff is at 5psi, maybe 6psi for at least some parts of it, since my boost gauge has "peak" mode so I can see what I'm bumpin'...just can't log it.

Oye...gotta read that thread again, "Throttle hang with 9653" or whatever, because it's baaaad. Does the automatic tephra have that problem as well?...I was guessing by the tables we have defined, that it might also be 9653 but dun really know.

Oh, and my accelerator was like, flat out stuck this morning when I went out to do some logging. I took it out from the pedal, re-routed it behind the intake, and adjusted the slack using the 2 bolts on top of the intake.....but it was weird to have no pedal play, so I put it back in there...just feels right. I also had my wife push the pedal slowly, to test if I was gonna brake my little throttle thingie, that's on the spring, because I thought that perhaps the WOT would break it, but meh...doesn't matter I guess, since I put it back.

 

I have no "throttle hang" with my auto lancer. But what exactly do you mean when you say auto hang, describe?

Your timing map is extremly close to mine, pretty much how i have mine adjusted, When im in boost im at 1-(-1) timing all the way up the RPM's. I still get knock at lower RPM's if i give it too much gas, 50+ throttle. That knock is pretty high bro

 

I have not noticed any throttle hang at all. I did have something wierd happen on the way home yesterday though. I was on the highway and had to slow down to probably 40 for someone then I got into the other lane and dropped to third and punched it and it started hesistating REALLY bad and almost bucking. I seen my wb was bottomed at 10. I am thinking I hit a really wierd load/rpm cell that I never would normally hit and its wsyy off but since I wasn't logging and everything checks out fine I might just have to try and catch it in a log although I don't plan on trying to recreate it cause Ill bet it was not good at all for the car it was a little too violent for me.

 

The throttle hang is a well known issue in 9653. I think I have it sorted out, by the methods the evo guys use. It's basically in any evo rom for 05+, not just tephra stuff. Has to do with decel fuel cuts and ISCV RPM adders. The lower load knock stuff is all showing up because I have my knock thresholds set to 0. I've logged the low rpm stuff, changed timing around, and I just don't see it going away....so I've put the knock limits back to basically anywhere above that nasty stuff. like, 0 for <1500, 50 for <1500-2500, and 30 for 2500+, that's load to rpm if it wasn't obvious.

Umm...this reminds me, I had a similar problem when I was starting from a stop with the A/C on, and I had not enough timing in the low load/rpm spot. I doubt that's the problem you had, since your timing is more aggressive than mine. Also, back in the day when I had a "cold air intake", it would vibrate if I started accelerating, regardless of gear, at the exact right rpm range and it wouldn't stop until I let off and started all over again.

Here any weird noises when it happened?

Also, no one has said much on increasing timing, and whether or not I should just do it at WOT. The reason why I ask is that when I started into boost...it felt nice and good as far as power. When I got up to about 3500 though, maybe 4000, I felt some hesitation, like I didn't have enough timing, the same or similar to when my low end timing wasn't enough. The way I had it before, my low end stuff was pretty weak, so if I were smoothly accelerating at low load, it would jerk a little here and there, but with timing added, it was much better. So the question is, how to I make all the map right, just do WOT and smooth from the low load spots, which are basically the same as when my lancer was stock (cause I am pretty sure those values are "right")....or do I try to hit every load/rpm range, and increase timing all over until there is knock. Just keep some sort of log of whereever I think I'm maxed out as far as timing goes, like a big game of "timing connect the dots"??

 

Ya I remember reading alot about the throttle hang. Even remember Senate talking about his throttle hang after he originally switched over to the evo ecu. I always tune my timing at WOT, only because this is the most drastic conditions the motor will see. I tried many many ways to tune its kinda hit and miss. I tried to bring my rpms up and then go WOT so I would go 2000 then wot then I would go 2500 then wot then 3000 then wot and so forth so I could get into some other load/rpm cells and smooth out through a kind of "connect the dots" as you put it. Even at 12 psi if I dont get any knock my timing at peake torque is around 2 degrees. If I get some (which seems to happen alot more on one of the two road I use making me think its the rougher road surface) It can drop down to -2 at times but I usually let off if I see that high of knock counts. I think I am still a little high in my load areas around 160 or so but I have been tuning my fuel which is pretty good now so I might switch back over to timing for some fine tweaking.

Also as far as my little incident not sure what happened sounded like it wanted to backfire on me I think I was going extremely rich, enough to temp foul the plug. I might pull out the plugs tomorrow and check them out.

 

If you dont have knock in the upper RPMs, start to increase timing until you get a constistant knock, then back it down to be safe, this is what im trying to do, my timing going into boost is nice, pretty quick but is hesitates up top because my timing from like 2500+ RPM is 0 or -1, so it does hesitate a bit. Ny timing is pretty much like this, from lower RPM to high: 22, 18, 11, 7, 5, 3, 0, -1 is how it usually reports back to me in most of my logs, 22 being cruising, 18 is decent throttle and 11- (-1) is when i start oushing the gas down and hit boost. So basically im just taking logs from like 1,500 rpm all the way up to 4000, and my timing is all zero's or in the negitives, so i just go to my timing map and spot out the loads and rpms where i see the low timing and i increese them 1 or 2 degrees more and then smooth out the surrounding timing values, your timing map that you posted a pic of with the knock, is very similar to how mine is. Im going to start upping the timing in the higher RPM's to get it to flow better

 

Yea, that wasn't throttle hang. That was a melted throttle cable. Guaranteed to happen to any and every turbo Lancer that doesn't take precautions (ie - wrapping the throttle cable in reflective heat wrap or insulating wrap). I've gone through 3 throttle cables since my first turbo kit. I plan on installing another new one and wrapping it one of these days. The newfound excess heat under the hood from a turbo and manifold will accelerate the degrading of alot of rubber-based parts. Silicone and stainless/aluminum will be your new friends!

 

I never had a problem with my cable at all since the build, my car tends to backfire usually at higher rpms around 5k+ but I just got my first cel in a while but it was a slow count so some where I need to tweak the timing to get that point fixed I might have missed something. so 03lance when you tune you basically work your way up? Like how exactly do you start off with 2k wot, then a 2200k wot? how do you go about your increments I might start over on my timing because you saw how low it was compared to your map

Met a guy with a 400hp supra, was like you wanna run I was hesitant at first because I just woke up 30 mins ago and was at the car wash "I thought I worked in the morning but I work the night shift" dude was dissing my car and said you should have INVESTED....

 

Ah gotcha, strange I havent had an issue with my cable... yet (knocks on wood)

Other than that wierd incident the other day I have never had a backfire. Steven I think your timing is too low in those higher load areas probably causing your backfire. That guy sounds like a douche. Any real car enthuisiast would be all over your car wanting to know every detail of your build. Its pretty unique the way our cars are setup. Alot of people in my little town love my car and are really impressed with the setup. Gotta buddy with an old camaro all restored, cherry and pushing about 450hp. He is always asking me about my car he like it alot

 

First time it happened to me was when I had my original 16G6 cable. I was accelerating to merge onto the highway and let off the pedal when I was at about 80mph. The car kept accelerating at 12psi. It was honestly the most frightening feeling a person could ever feel. I turned off the car and pulled over to the side of the highway. When I started the car the RPMs instantly jumped up and began bouncing of the rev limiter at redline. I killed the engine again, popped the hood and inspected the throttle cable. The cable was sticking inside of the covering of the cable. The covering had heated up, softened a bit and began melting to the metal throttle cable. The best solution and advice I began giving members was to tuck your foot under the accelerator pedal and pull it back up if you think your pedal is sticking or your idle is too high for no reason.

 

I am glad this issue was brought up, I had my hood popped today and sure enough where my cable dipped a little too close to the header where I am missing that other clip the cable was soft and a little melted. I have not had an issue but I did tuck the cable up higher further away where I am pretty sure I should not have anymore issues

 

Damn edit again, so anyone know how to use the dundas gauge wizard in evoscan? I have been working on it for awhile and I must say, I suck at it lol. How do you add numerical gauges to your existing template of circular gauges?
