i suppose it depends where you live, but where im from i can rev out 3rd gear 100 times without seeing traffic. tons of open road here, its awesome for a fast car. im not a fan of top speed, i just rev out 3rd usually.

what you described is what i like as well, which is why i got the setup i got. i stuck with the stock im and stock exh manifold so i didn't suffer any mid range power.... imo tq is funner than HP. a car with tons of tq is an adrenaline rush.

ill do an occasional highway pull with another car, but im not really a fan of street racing myself either.

i was just trying to get an idea of how aggressive the maps responds to changes in tiny incriments.

i have not even begun to tune my evo yet ,but it doesnt seem very hard. I only have prior experience with dsmlink.

 

It is addicting thats for sure. I need to load that virtual Dyno.

 

Paul,

Back on page one, the OP stated in post 18, that the evoscan was having issues logging 100%.

I am experiencing this same issue. Did we ever figure out what causes this? I have been knocking it up to hardware issue... But it sounds like maybe a glitch in the program.

Thanks in advance. I am running V 2.5.

Edit: Also, question relating to topic and the Low Octane Map. What is the general rule of thumb to get the Low Octane Map tuned. Do you utilize your High Octan Map, and then just detune it doen a little? What areas, just spool up and wot? Thanks again.

 

Ok so I logged 3 pulls while monitoring knock and AFR during the pulls to make sure everything was safe enough to continue the pull. The AFR definitely seems richer to me. I think Its close on the mid and needs to taper much more on the upper.

Paul I did not turn of lean spool yet. Im assuming that when I do turn it off its going to richen up the spool quite a bit? Is the reason for turning it off to directly control the "lean" spool via the fuel table?

Ive put the map trace below for one of the logs. Ive also attached the 3 logs in a zip. I need to be sure im staying %100 in the throttle. some of them im going down to %98 or so mostly because im looking at the laptop screen and back at the road and getting ready to let off if needed. Im trying to be safe about things (both driving and tuning).

I also turned the boost up just a hair looks to be about a 0.5psi increase maybe 1psi. So im seeing 23psi now and tapering to 22, 21,20 psi by redline.

 

I installed Evoscan on my windows 7 machine and changed the default install directory to something of my choosing. I used C:\Apps instead of the C:\Program Files\Evo Scan etc etc.... This may or may not help but it seems to work for me now. If you are using vista though be sure to install in a different directory then program files it will save you a lot of headaches.

Good luck

Upgrade to the newest version of EvoScan.

You may be exceeding 100% on the throttle position sensor. Especially if you did the throttle cable flip and didn't properly adjust the throttle cable play.

Then try making adjustments to you throttle position sensor.

1) turn on the car (not start) and start logging throttle position with EvoScan.
2) on the back side of the throttle position sensor there is 2 bolts. Loosen them.
3) while looking at the computer open your throttle body to see if you are reaching 100% full throttle.
3a) you want to hit 99% just as the throttle plate is coming fully open (100% is ok too)
4) turn the throttle position sensor and test again with the throttle body valve
5) once you are happy with the result....tighten the bolts and call it done

 

dont do any pulls with the laptop sitting on your lap thats dangerous..... i just set it to log put on seat and do the pull then stop it when its done.... watching the laptop during a pull is not smart.. i dont recommend that at all.

 

Yeah....when you are about to log a pull...start the logger and leave the computer sitting in the passenger seat. Keep your eyes on the road.

I made mine so I can press the space bar to start and stop the logger. It is easy to reach over hit the space....listen for "link engaged" then do the pull...reach over and hit the space again.

 

ah good idea. i forgot you can set that stuff with evoscan. its even dangerous moving the mouse to hit the button on evoscan when driving.

 

Ethan....did you read....https://www.evolutionm.net/forums/ec...s-enabled.html

You will gain valuable information about tuning with Lean Spool enabled. It is very difficult to get consistent pulls with LS enabled. This is the reason most "tuners" disable it.

I recommend you read that link before any further tuning.

 

please sticky this in your head.

 

Ok sorry for the confusion guys. Im not doing the pulls with the computer in my lap. Nor am I staring at the monitor during the pull. Your right Tom that certainly isnt smart and is lacking quite a bit of common sense. Especially on a public road.

Paul I have it setup exactly how you suggested. Its on the passenger seat nad Ive changed the "hotkey" for start and stop to be space-bar to make things easier. This is how Mitsulogger is setup as well as long as you dont click anything after starting the logger. (meaning pushing space bar will activate what ever "button" was your last click) The great advantage with EvoScan is the audible alerts. The link engaged really is a great one and the warning engine knock detected with a proper threshold.

So what I was saying is that I have an AFR guage setup on the computer during that first set of pulls to make sure things are in check. During the pull it stay pretty constant I am just glancing to see the value. Now that I know things aren't running at 5.0:1 AFR or 14.0:1 AFR No more need to look during the pull.

I think it should go without saying that while driving especially while doing a pull eyes on the road like all of you said....Give me a little more credit then that..ha!

Thanks for the link Paul Ill give that a read and decided what to do with lean spool.

Just read through the whole thread. Good info Paul! I posted a question on the thread. Im confused one weather to tune with it off then enable it or tune with it on....

-Ethan

 

keep it off... its not consistent enough to be used ,the a/f does different things each pull from what ive experienced with it turned on.

also..... make it easier on yourself and reorganize what you're logging on evoscan. for example make tps show first, then rpm, then knock , then knock voltage, then wideband, 2 byte load , etc.

to do this, just open evoscan and use the "move up / down button and it will organize the stuff it logs differently on your log file. right click on value and the menu will come up with the move up/down option

 

Ill have to disable it and see what the logs say..

Side not on logging parameters. What can I do with reading the ariflow? Im logging the 2byte airflow and somewhat udnerstand it. Is there an area where it is explained a little more? Also you mention knock voltage? Im assuming this is the voltage seen at the knock sensor but what can I use this voltage to determine? Especially if I dont know what the voltage levels corespond to as far as knock and noise etc...
