watch these videos a member made on tuning you will greatly increase your knowledge on how the whole tuning thing works

 

I have heard of people starting by dropping everything by 5 degrees but I have not and will not reccomend anything like that yet as I am still new too

 

Thanks, I had been trying to find those for a while.

 

no prob man also the sticky in the evo tuning "how to tune an evo" Is very good I printed it all out and have been studying it and referring to it when looking at my logs

 

its best to start at the lowest RPM you encounter knock and pull timing in that one RPM sector. sometimes if there is too much/little timing at the beginning of the pull, it can throw knock all the way through the RPMs.

 

All I can say is fantastical find. I am liking where this thread is going. I wish someone would create a lancer specific tuning thread, even though Im pretty much positive everyone will run evo ecus in the future lol. And I guess it still teaches us how to do our own ecus but with alot of mumble jumble that doesnt apply to us. Anyways, once again, great find.

 

Sweet good to know

 

Is there a certain amount to pull?

 

Generally for every knocksum of 3 you pull 1 degree of timing so if you see a count of 5 or 6 you would pull 2 degrees etc. and then log to confirm the knock is gone

 

thnx 03.

@crewdawg130: thnx for the books man.

my school starts today, so i dont think im gonna be moddin my lancer pretty soon.

 

wow, ok. Remember that the loads on that map are for a Naturaly Aspirated car ( unless you have a evo 8 ECU......do you?????). SO, youre gonna have to scale them so you can tune anything ove 0psig (or ambient press). I wouldnt even try to boost that thing on a MA map. Is way to much timing for any type of boost. Youll create to much cylinder pressure and pop something.

Also. yes the ECU will pull 1deg of timing for every 3 that she see. That doesnt mean that you gonna make her knock to figure out your timing curve. That old school crap that"make her knock then pull it back" is that just crap. Example. let say that At peak torque you have 6deg of timing. then you give it some more to see what happens, then nothing, so you keep giving it more untill she knock like around 12deg. now you pull her back a notch....ok! thats fine, but she stop making power at 8deg of timing..... so why would you wanna give her all that if she dont need it. you want that cushion. THE ONLY WAY YOU CAN SEE THIS ON A DYNO...

Just my 2cents.

Also what type of map sensor u have??????

 

Youll se the reduction of timimng because thats what is suposse to be like. not because of knock

timing on boosted cars looks highest before peak trq, lowest at peak trq then ramping up till read line......

 

True the peak power isnt necessarily made at the most advanced timing and a dyno is the most effective way on doing it but if we can get them close without spending the money to use a dyno I am ok with being a couple degrees over if thats what ends up happening

 

You will most likely not ever reach MBT (Minimum Best Torque ... where more timing yields no more power) on pump gas, so it is perfectly logical to add timing until you encounter knock and then pull back a couple of degrees.

If you are on C16, E85 or similar then you do need a way to monitor torque output as you may reach MBT. You don't need a dyno for this. You can use a software application such as Data Log Lab for this assuming your pulls are consistently in the same place on the street.

Modifying timing does slightly affect the AFR, but not by much. If you dial in the AFR then tune the timing, you will only need to make minor tweaks to the AFR to get it back in line ... if any.

My suggestion for tuning a boosted lancer is to first apply the modified MAF Scaling settings so that you don't run out of fuel up top. Then, rescale the fuel and timing maps to 110 load. Next, pull about 8º of timing from 80 to 110 load before you do a single pull. That should keep you from seeing knock. Pull more if needed. Set the boost, dial in the fuel and then the timing and that's it.

 

Never mind....

There you go guys, is that easy..... later
