tunning for dummies!!!!(can anyone help)

[pearlwhite turbo]

I've been looking all over the forums to find a good source for "learning how to tune". Can any one point me in the right direction? Is there another source for noob's? I just got a Maft-pro, I also have a SAFC a freind gave to me. I see you can combine them both but is it worth it?

I know this is some NOOOOOB sH**t, but I won't learn unless I ask.

They will do the same thing, install the MAFT-PRO, buy a wideband, and sell the SAFC. Then do some reading on how to tune under WOT to your desired A/F ratio.

if you don't understand what you're doing, you're going to do some damage. the only thing i can recommend is finding a knowledgeable car-guy or tuner in your area that's willing to help you....you need to learn the basics- how a car works, what each tuning device does, etc. then move on to what happens when you change things, etc. i CANNOT recommend attempting to do anything w/o the proper knowledge....

All I've ever heard from people who teach themselves to tune is "you blow up alot of your own stuff before you get it right." And when they use the term "popping engines", you know its going to be expensive.

So in short, seconding drjonez: find someone who knows what they're doing to teach you the basics.

Want to get rid of that SAFC? I would like one... but back on topic, in order to tune you gotta have a good understanding of all the electronics on your vehicle for one thing, and then you gotta know what each device does, and how it operates. Once you get a good grasp on that, you can figure out what needs to be changed in order to get what your looking for.

Example - I know plenty of people that have wired potentiometers on their rear O2 sensor in order to play around with their A/F mixture without the help of any chips or controllers... just need the basic understanding of how everything works - then you can start to change things in order to lie to your ECU and send it a signal of your own, rather than having a sensor send out the real signal. (that goes for vehicles in general)

Just don't do anything if you don't know exactly what your doing, have someone with some experience give you a helping hand.

If you are definetly going to take the step of doing a tune, then get everything hooked up, make sure that everything is set to 0 or whatever (no changes). until you get a wideband don't change anything. Without the A/F ratio you can't see whats going on. But you can get all the devices working in preparation for the tune

i'm going to be using an hks vpc, so i'll never have a "sweet spot," correct? changes in temperature and humidity will effect the useability of the vpc..or so they say :chicken:

pretty much....

 

[MKIIINA]

/\ not exactly. you can use an safc and help fine tune things. if you are just using a vpc its a very rough tune.

the safc is something i would definately not just sell especially if you arent sure how you are going to tune things.

and dr.j just because its not a maft-pro setup try not to bash too much without explaining things to people.

Any one out in the NJ area, that can help me out??????

Theres 3 *basic* areas that you will have to mess with to "tune" your car. Fuel, timing and boost. You MUST start conservative with all of them to avoid a boom.
Ive only messed with the maft-pro a little, but it seems very user friendly. All i can say is start out with stock spec timing and boost and work your way up. AFR's NEED to be monitored whether it be an in-car wideband, or on a dyno. Its not rocket science, but its not for the timid either. If youre really uncomfortable with it, see if a professional would be willing to show you the basics as he tunes your car on a dyno....

talk to jeff tamilus or JTamilus i believe on sm.. he's a wicked cool and extremely knowledgable guy who im sure if you asked nicely he'd walk you through the basics or atleast point you in the right direction

let me suggest a really good book your understanding the basics of engine management and tuning the book is called "how to tune and modify engine management systems" Is by a fellow named Jeff Hartman and its a really good read it cost 30.00 bucks and can be found at most barns and noble its worth every cent if for nothing more than a referance guide for different formulas like injector sizing and what not.

Check out page 13 its got an awsome pic of a twinturbo 7m that makes 900hp built by norwood performance. Only thing i don't like about the book is how so many of the projects use motec and motec is noware near what your average user is going to be useing.
