I recently had a joint tuning session with JoT and he had a slightly different tuning style when it came to peak torque.

This thread would be to compliment the timing map thread to see what the cars are hitting during WOT. Please include Timing, Load, Fuel, AFR, boost - if possible - and list mods . Please feel free to add more parameters.

Obviously I don't want to impede on anyone's intellectual property so if you were professionally tuned i would ask you ensure it is ok with the tuner to post a log.

I would start the contribution but i recently lost my laptop HDD and never backed-up my logs so i have nothing to start with...

 

Fuel, AFR, boost, and mods should be listed as well. All will have a big effect on what timing numbers are being run.

 

Updated original post

 

I already have this on another thread so here is mine. This is a self tune on Tephra V7 ROM 9653. Mods are in signature. Feel free to comment or critique?

This charts shows the most common log items.




This second chart shows boost and airflow in Lb/Min for the same run. This gives an idea of how good or bad the turbo is flowing.



I will now try to add more WGDC to have a little more boost at top.

 

I like the idea of this thread! I will add my contribution when I get home on my laptop.

 

Yep, me too. I'm curious to see the various different tuning styles and how mods effect the ability to run timing approaching MBT.

How did you guys differ? I assume one of you liked a lot of timing at peak torque and the other a little? I, for one, favor lower timing at peak torque, since it is the part of the curve where you are most likely to get knock and most likely to throw a rod though your block. Also, unless you have a dyno where you can monitor this exact area carefully, especially on a fuel like E85 (which isn't knock limited), it would be easy to surpass MBT and really damage your bearings or throw/bend a rod.

 

realistically this should also include an AFR reference if possible since that will also be a contributing factor at a given boost level.

 

C'mon....post up some of your "tunes". I would love to see how I compare to a "pro" tuner. Heck I might learn something in the process.

Look for my stuff after I get a good log of a pull. I've been tuning for cold issues lately so I don't have any pulls.

 

We both follow the same sort of method. Set boost to a desired level, give it as much timing as she likes with minimal knock. Adjust fuel, adjust timing, repeat.

Our difference was ramp rate of timing. He held the peak torque timing advance longer than i typically do. I typically hit peak torque then ramp timing up as soon as the load "spike" levels off. I have seen both ways work it was interesting to get that perspective. That sort of ramp is what i am interested in seeing with this thread.

 

That's where having a dyno or the VDR tool comes into play. As long as you're not past MBT, I would ramp up the timing as much/as quick as possible as long as power is increasing and there is no knock.

Even the VDR tool would be good enough to capture this. It's just the peak torque area that would be difficult in the VDR tool because of the averaging going on and so much data changing rapidly in that specific area. So, of course, there would be some small RPM window where the timing may be flat. But, the ideal ramp rate could be determined very well from the tool just by monitoring increases in torque while avoiding knock.

 

Name the car you'd like to see I think I have been putting pretty much all of them up including my car already. I dont tune cars anymore than someone makes art. It all just kind of happens the way it happens.

 

Here is the complete list of logs of my car this year:

It will only be available for 10 downloads so someone needs to host it if they would. Also before anyone gets the wrong idea about my last comment, I am not trying to say I am an artist. I meant that what happens happens and if it works it works

yeah we were playing on a dyno i am just interested to see how other people's timing maps look in real life.

 

will post mine later on with everything on the log....nothing fancy though...

peak timing at a reasonable number ramping up to redline in a nice smooth fashion

 

In my case I can not add much timing after peak load witout knock. I have to wait until 6000 - 6500 to ramp timing. I think it really depends on what the car likes. Unless there are any secret tips to ramp timing without knock
