Tuning capabilites

just wondering it anybody knew if either RRM's piggy or Ecuflash had the capabilities to tune up 350whp? never really found any past posts with eithers limits so it would be nice if someone knew

I dont believe ecuflash has a limit the limit is sdetermined by your ecu.

I wouldn't recommend the piggyback for tuning those numbers. EcuFlash has the ability to tune way past the power a Lancer can make. And if you are in need of something more, simply swap over to the Evo ECU and go from there.

well regardless of all the info ive gained from here, im a complete tuning newb, so how would ya tune the turbo into the lancer's timing/fuel maps to keep cel from coming on? an i downloaded ECUflash a while ago, but gave up on it because i couldnt get def files from your list to upload correctly, and i cant find the same 90 dollar cable everybody talkin about...unless it costs more now???

I just got done installing my custom 16g turbo kit about week and a half ago and no CEL at all. Really the only way your gonna turn your engine light on is if you run too rich or too lean, or accidently slice a wire or something to a sensor while doing the install. I still have alot to learn about ecuflash myself and really even though I did easily 50 60 hours of research online about tuning I really didnt start learning until I started tuning my car and making mistakes and learning. As far as the def files dunno there maybe try again if its been awhile. DL the latest ecuflash and thentry redownloading Senates master definitions file. Make sure you get the tactrix 1.3 not the 2.0 cable, I had to find mine for sale here in the forums. They go really quick I found out so you wanna act quick if your serious about boosting and using ecuflash to tune.

As far as tuning turbos all I can say is read read read man, Watch These videos and read this sticky all the way through. Also this thread is very long might have to read in sections lol but it helps alot too. These say they are for tuning an evo but pretty much everything relates to all cars using ecuflash

lol yeah i know what ya mean about the reading. yeah that info about the cable helps, as far as actually tuning, i got a friend who has a lot of ecuflash experience. My only problem is just getting the definition files usable for the program so that i can get a good feel for the program itself.

oh yeah 03, as far as tuning for turbo goes, ya mean you can just plug in a/f and timing numbers into the lancer maps and the ecu will just "recognize" the boost pressure as if the engine has always had turbo and wont trip cel for that abnormality??? know more about Ecuflash, i must

you CAN use it but its pointless using it on an old lancer.
anyhow, heres a link for a new tactrix cable 1.3U. thats the one i bought.


Happy Tuning my friend.

No. There are two modes our cars ecu works with. Its Open and Closed loop. Closed loop is used under partial load/throttle where you're not straining the engine. The ECU reads the data from your o2 sensor, and adjusts your fuel trims based on the fuel maps to achieve stoich readings. When you go into Open Loop mode (when you're above a certain threshold which is set on a turbo car to be when you start to spool and create positive pressure) the ECU uses the open loop map as a guideline for how much fuel to put in at a predetermined throttle vs RPM point. It doesnt take into account what your actual AFRs are, it just puts in what it "should" be to create a rich and safe condition. Tuning the fuel maps enables you to add or subtract fuel at set points to make your car run more rich or more lean. You MUST have a wideband o2 sensor installed so you can know what you're running at what rpm and what throttle position. When you log those readings, you can go back to your maps and say "ok i ran lean here, so i should increase fuel delivery on the map"

Thats just the basics . Then theres timing

This is exactly where I am at right now I have my open loop thresholds setup pretty good and getting my afrs down a little at a time

Well, yes and no. The Lancer ECU won't recognize the boost pressure. It will interpret the increase in airflow as, just that, an increase in airflow. At roughly 5-7psi (depending on the turbo and setup) the ECU will be interpreting just under 100% load (give or take). That's not to say you can't tune for boost. You just need to adjust fuel/ignition accordingly to the load% your ECU is interpreting. It is at those cross values in the fuel/ignition tables that it is pulling from.

With an Evo ECU, on the other hand, it recognizes boost pressure right out the gate and will register the correct loads of 100%+ with boost pressure. There is also a greater range of values to tune with much larger fuel/ignition tables.

Well that makefeel a little more like I am in the right path at 5psi I am hitting 95% load values

ok, ok....now that cleared up a lot of thoughts i had about turboing, sounds like i may end up going 4 the Evo 8 ecu, when the time comes for turbo then, at least after i build the engine, since I was just going to buy roadrace's kit and use the piggy while on stock internals...but while n/a, Ecuflash sounds tempting...

So, is datalogging required for Ecuflash tuning, or can i just dynotune with just a wideband o2?

And thanx for the info and assistance so far, guys are epic!

As far as I know its not a no yet just no one has tried it to my knowledge I say try it. You can always resell the evo ecu.
