20 at redline is quite a bit. I don't even think 9's on e85 run that much timing up top.

 

Definitely looks better but there's still some choppiness in your 120 load column.

 

i was off a tad (and i dont my latest logs on this computer) but the last log i did when the weather was in the 70s im logging 13* at 7000 and 16* at 7300 with no knock.

 

Oh, lord. You're right. For some reason I didn't even notice that. Duh.

 

No prob man! It happens to all of us after you spend too many hours looking at colored boxes with numbers in them

 

It definitely messes with your mind!
Thanks for your help.
I'm going to fix that and lean out my fuel tables slightly, load it up, then do some logging. Wish me luck!

 

Here is my car's timing map. Now before there is war, my car for some reason does not like more timing, I hit 300-310 load at about 3500 rpm and if I give it more timing she starts knocking.

3" TBE
Invidia dump
255 Walbro
LICP
Drop in K&N
Grimspeed 3-port

The car is pig rich, boost spikes at 26-27psi drop off to 24-25, stock E9 turbo. Rev limiter is set at 7000 rpm at which point she takes only 9* of timing. The way it is set now there is some sporadic 1 count knocks but they are definitely phantom as they appear in different places during different logs. Fuel is 98 RON (suppose to be). My High Octane map looks more like a Low Octane map to me!!

Your thoughts??

 

I have a hard time believing that your car can't take more than -5 degrees at 3500 rpm. How rich is it running?

 

I have not tuned the fuel yet 'cuase I am still waiting on my LC-1 to arrive. As soon as I have wideband I will be able to get the AFR's sorted which should allow me to give it more timing.

This is how I got the tune when I bought the car.

 

You really need to get a wideband hooked up before you do anymore tuning. There's about a 99% chance that you are not hitting the numbers in your fuel map and the only way to know what the car is actually running is with a wideband.

 

These the maps that came with my car, I believe there is room for improvement after reading through this and other threads. Any generalized opinions would be welcome. During my last 3rd gear log I read 4/5 counts of knock from 3437-4437 RPM.

Evo VIII on 93.

 

Are you running methanol? Have any logs or a map tracer pic? It seems to me that if you are running straight 93 oct. then that is a bit to much timing through the mid-range.

 

So after experimenting with turning up the boost to 30psi, my car is knocking at about 6400 RPM consistently. My theory is that it's blowing hot air around that RPM. I tried reducing timing and it seemed to help. I just want to know what is really going on. In the first pic I know it's running a little lean. I added fuel in the 2nd pic the AFR's are good, but I think either the timing is too high still or that the turbo is running hot. What do you all think?
BTW, I'll be reducing the boost to 27-28 soon. I just wanted to see if there were any gains. There were, but not enough if I'm going to be knocking.

 

The fuel map could use some smoothing, and like mt057 said, timing might be higher than "normal" in the mid-high rpm range, but if the car takes it without knocking and you're on straight pump gas, all the better!

30 psi is way out of the stock turbo's efficiency range, you would probably get more gains by dropping the boost some and trying a bit more timing instead. The car should also be more consistent with less boost.

 

Straight 93, no additions. On Tuesday it's going to be 91 as I'm forced to drive through Oklahoma. I have attached a 3rd gear log, but I can not for the life of me get map tracer to work in Evo Scan 2.7 / 2.8.

I've read with Ignition not to jump more than 3 degrees from cell to cell, how does that apply with AFR from CtC?
