Hey guys,
Want some opinions on how I did.
The way I approached the tune was to be around an 11.7-12.2 AFR.
Then give it timing until I see knock.

The car feels great and pulls hard to 8K.

The log is starting in 2nd gear then I paused and start back in 2nd gear and then shifted to third.
Wanted some feedback on how timing looks/ timing map.

So how'd I do? Any adjustments I need to make?

That timing is agressive!!! but for your turbo and E85 I think is ok!

 

I'm assuming you are talking about the lower rpm's.

Since I'm not seeing knock is it safe to leave it?

 

I plan to go to a dyno soon, rough idea how much power I should be making?

 

With E85 you need to also be looking for MBT, not just knock. Did you use virtual dyno to check changes in power when you made changes to timing? If you add timing without seeing gains in power you may have gone past MBT, in which case it would be wise to back the timing down a bit. The timing map also looks like it could be smoother.

EDIT: Also, you need to do a 3rd gear pull from ~2500 to ~7000 rpm to get a decent log, 2nd gear is too short and you don't get enough samples per second in evoscan. Further, you're logging a number of things you don't need which are slowing down your logging, namely fuel trims, o2 feedback and afrmap. You also don't need loadcalc since you have 2byte load. Finally, make sure you've UNchecked "log to screen" as that slows down the logger nearly by half.

Once you have a 3rd gear pull you can use Virtual Dyno to estimate your power. While you're at it, you could do some pulls on maps with less timing to see if the timing you have now gains you any power or if you've gone past MBT.

 

Thanks for the idea. I really wasn't using my virtual dyno and was relying heavily on knock.

I have installed a virtual dyno and what I'll do is log my current rom then decrease timing and log. If I don't notice a difference then I will go ahead and lower the timing until I notice a difference than I know I am at the point of MBT.

 

That should also work.

Good luck!

 

well ran into some issues, actually a big issue.
Sometimes my car would just fall on its face around 3500-4700rpm. I noticed it once before but today when I lowered the timing it started doing it all the time. I know its not the timing effecting it but its real bad! I am making another thread since this isn't the correct place to put it.
Just to get the gist of the story, I started noticing this in 2nd gear 4k rpm. I punch it and all of a sudden the car starts to move then BAMM, its like it hit a brick wall and back fires!

 

Fuel cut. You are hitting a higher load then what is in your Boost Limit table.

 

thanks for the response razorlab.

When you refer to the "Boost limit table" are you speaking of the Boost cut load and the boost cut delay?

It does feel like fuel cut. (I had a 1gdsm before , know how it feels)

I thought if i were to change the settings on "Boost Cut Load" and "Boost Cut Delay" that fuel cut wouldn't be an issue.

Is there any other setting?

 

So I figured it out!!
The issue was low gas, yes it sounds weird but it is was low gas. Now to figure out why t happened.
Here is my reasoning.

I recently installed a Full Blown double pumper and am only running one pump. I do plan on running the second pump but currently am not. Now I am not sure if the housing lets the pump hang low enough, therefore is not submerged in the gasoline causing it to run out of gas.
Now I know why it is recommended to hook both pumps no matter if its needed or not.
I plan on hooking the second pump on soon as testing my theory.
Any who, I'm glad I found it.


I took the advice and lowered the timing. How does the new timing map look?

 

i would suggest not to rely on knock for finding MBT on E85 as you can and will probably go past mbt before you have knock appear. use virtual dyno, a great tool to have when tuning.

AFR map needs some work, smooth it out and get rid of the dip you have in it.

The timing needs some work, def needs to be smoothed out very block style tuning around spool and peak tq timing. work on making these smooth and progressive you should not have large jumps like 11.3-10 in ur afr map or 11-6 in the timing map. Take a look at the timing map thread.

id also suggest rescaling your maps to have better resloution under boost rather than idle and cruise. Or convert to tephra rom.

I hope this helps and good luck with tuning!

 

I agree with the smoothing of the timing map...there are some instances where the timing map is going up like it's supposed to...then to the next cell it goes down...then back up...very inconsistent.

I.E.
Load 131 column going from top to bottom...there's a point where it goes. 21,21,22,23,14,15
Load column 100 does a similar thing as well...

 

Thanks for the response, I'm going to make the adjustments and post another timing map.

 

Keep us posted! id be happy to review them for you and give you feedback! good luck and keep working on it! takes time but you'll get it!
