I was just wondering i'm reading on all this stuff about ECU tuning and evo scan etc..... is it worth tuning a stock evo? and can you just use a laptop to tune at home? and log? can you change boost psi with tuning ?, I'm pretty good with computers, its just i don't understand the basics of tuning if anyone can help me out..... or point me on what i need to search and read.....


1. What would i need to get started (software+ whatever else), have a laptop what is the criteria for the laptop, what cables do i need? and is there a point in tuning a stock evo?
2. how does logging work what software do i need and once again do i need it on a stock evo?

thanks

 

bump anyone? I know you need tractix cable and evoscan i just need help getting the basic's down

 

^^ well, that is the basics...www.mellontuning.com click on equipment, and on the bottom is a video showing how to connect the trac trix and upload/load a rom...also in the ecuflash forum is a post showing how to manipulate the map cells if you wish to tune yourself.

 

here is a good link for you https://www.evolutionm.net/forums/sh...d.php?t=237869

I would advise searching around and seeing what you can come up with. There are two glossaries I linked to at the bottom and they may be a good start for you.

You need the following:
1. Tactrix Cable
2. Evoscan
3. ECU Flash

You will see gains by altering the stock map on your Evo. Logging is basically recording what happens in your engine as it advances... in other words... if you were to floor your evo from 2500rpm to 7000rpm, what is happening with the engine. This is what evoscan does. All logs will be viewable in an excel file which you can send to your tuner or use for personal tuning. Evoscan also has other feature such as real time graphs, gauge packages, etc.

EcuFlash is where you can view and adjust the actual fuel and timing maps and then transfer them back to your evo's computer called an ECU which is found below the glove compartment.

It is in ECU Flash that you will be able to change your boost limit and rev launch limit, etc.

I would strongly advise tuning your evo even if its stock, you won't be disapointed and you may notice a better gas mileage.

PM me if you have any questions, I'd be glad to help you out. Theres a million different threads that touch on this, so you will find it helpful to browse the general engine management and tuning forums.

Furthermore, if you're looking to increase horsepower, an exhaust and a tune is an easy first mod that you will make noticeable gains with. Otherwise, you can lean out your stock map (increase amount of air to parts fuel) on your stock evo to make gains without modding.

 

on top of what everyone else already mentioned...

you should look at a few engine tuning books as well. There is 1 good book by Jeff (Hartsomthing) called, "How to tune and modify engine management systems."

There is a good section called "engine tuning 101" that will walky you through the basics of engine tuning.

You may want to invest in these as well if you plan on tuning engines:
1. Wideband O2 sensor
2. Pyrometer
3. G-Tech type device (for measuring changes to tunes)

 

p.s. Innovate makes a great wideband that includes one of the better datalogging and tuning programs called "Logworks" that is compatible with the Tactrix cable

Here is a link to the book mentioned:

The first step before tuning is to make sure you understand all of the tuning language. When I say language I'm refering to knock, load, A/F ratio, etc. That you can easily get by searching and or using google outside of the forums.

 

As stated, there is a lot more to tuning than just having the ability to change settings.

To answer one of your questions, you cannot increase boost pressure with just a tune. You can lower it, but you cannot increase it without some type of physical modification. this could include an aftermarket boost controller or changing/removing a restrictor pill from the BCS lines.

Do yourself a favor and spend a lot of time learning about general tuning methods and the Evo ECU before you start to make changes. ECUFlash is a free program (www.openecu.org) and you can find maps to play with at www.aktivematrix.com. Read the posts in the ECUFlash forum here and at Active Matrix and play with the maps you've downloaded.

When you feel comfortable with the theories, principles, software, tables and values, go ahead and order yourself a wideband O2 and the Tactrix cable.

Remeber, start small and know what your goal is before you change a single setting. Tuning is easy, but it's even easier to do incorrectly.

 

thanks for the help everyone, i'm starting to read more and more about it, and this all helped me get started, once again thanks
