Thread: The Amateur Tuner

    Re: The Amateur Tuner

    I just added an Injector Scaling section to the write-up. Now I am on the third post in the thread. The second post maxed out. Please comment and tell me if I missed something essential. I tried to keep scaling as simple as possible. I hate injector scaling.

    Re: The Amateur Tuner

    Hey Neji-
    Never wrote you back on the VVT map you posted.
    AFR, definately .5 leaner. Had to redo a few parts of my fuel map.
    Boost, much more responsive, and the dip in boost @ 4K is minimal to gone now.
    RPM, definately have to set your RPM @ 1K... after about 5 start/stop cycles the car wants to go back to normal idle... it can, but it feels a bit rough. Set RPM for 1K, and smooth idle.
    IMO, the car is much peppier now. Boost in 4th and 5th can be achieved at a minor blip of the throttle, i.e. .5-1 bar at 2K in fifth gear.

    Thanks for posting that map O0. IMO, it is much more aggresive than other maps you see, and you can definately notice the difference.
    Thanks again-
    Socal

    p.s. been running it over 1K miles strong now.

    If you do not like a lumpy/slightly high idle, then change the numbers that are 3 in the top left hand of the map to zero. That will take care of the problem.

    Added a legal disclaimer to the first post. I want people to understand that tuning is dangerous and if you are concerned about damage to your car your better off leaving the ECU untouched.

    Is it not working with version 1.0? I never tried it on 1.0, so I have no idea how to make it work. You can ask on the Ecuflash forum and see if they can help you.

    Re: The Amateur Tuner

    alright yeah ill do that i guess. Im just using mitsulogger right now for the fuel trims. Ive been idling for like 30 minutes and still at 0 trim with my 720s scaled at 680. Im gonna go drive and see what my mid trims do.

    Re: The Amateur Tuner

    So I got my injectors scaled real nice theyre under 1% for low and mid.Â* Also I got the mod to work for evoscan 1.0 by adding an asterisk (*) between the number and the x in the formulas that were changed. So instead of (0.1961x)-25 for the function its (0.1961*x)-25

    Re: The Amateur Tuner

    I know you said that one should not change the low octane maps, but after scaling injectors, disabling lean spool, and retuning, I found that the low octane maps were actually significantly leaner than the high octane maps. Is there something I am not taking into account here, or did I do the right thing by making the low octane maps richer?

    The Low octane maps are only used when your car knocks consistently and the octane flag decrements below 100. At that point, the ECU starts sampling the low octane fuel and ignition maps.

    On the Evo 9, the low octane fuel map is leaner than the high octane fuel map because the low octane ignition maps are very very retarted. On an Evo 8, the low octane fuel map is richer than the high octane fuel map because the lowoctane ignition map is not as retarded as that of the 9.

    I would say leave the low octane fuel and ignition maps alone. They are a safe harbor that the ECU uses if/when your car encounters consistent knock.

    Re: The Amateur Tuner

    Naji,

    Any chance you could start an "amateur Logger" thread on how to do the logging and converting you use when tuning? That would be much appreciated.

    Still, wouldnt it be better for the ecu to add fuel when it detects knock rather than pull it?

    Correct. If you are really concerned about knock, then go ahead and make the low octane fuel map richer than the high octane one. Keep the low ignition map the same. That will make it ultra safe.

    Do you tune Rally cars?
    (pir·ate-hook·er) noun<br /><br />A female who frequently whores the male sex. This species of women are usually found wearing way too much make-up while flirting with men old enough to be their father and/ or engaging in fornication with said old men. Also falsifying information for sponsorship. Pirate Hookers are also known to be extremely ignorant.

    Re: The Amateur Tuner

    damn you Naji!

    why does your timing map have to be so knock resistant! ARRRRRGH!... I cant add anymore timing from 6K and up!

    I want that extra .5Hp at 7K! AHHHH!
    ...stupid 91 pisstane. :D

    On another related note:

    I found out today that knock sum pulls engine load for every 5° knock... I went from 220 load @ >6K rpm to 198-187 load...
    ...which actually leans out my AFR by .5 as well... not good.

    Re: The Amateur Tuner

    ^yea, im pretty sure about that.

    As soon as it hit 6°knock the load dropped @6K by 10, when compared to 5 minute prior logs.

    I was getting 218-212 load at 6250 tapering to around 210-100 at 7.5K, then after the changes it started knocking pretty bad at 6000 on up, an load dropped to below 200. it started at 200 @ 6K then was at 189 at 7.5K.


    p.s. i need to learn how to rescale the maps to get that incrementation at different RPM's...

    got a link to any threads? maybe on openecu?

    man i don't even tune but want to learn and I'm reading this thread and i must say, it is hella helpful for me and understanding things sometimes does take a couple times of reading through a certain section. thumbs up!
