i want to learn to tune....where do i start...are there any books i can read? i want to learn the basemap thing, street tuning, and dyno.

 

Yea there are deffinately books out there that you can read. Google the book that Greg Banish wrote on engine fuel injection. I think thats a good starting point

 

ok cool...thanks...any info helps...

If you want to learn to swim, you can read about how to do it all day, but you have to actually jump in the water to learn and get comfortable.

So if you want to learn how to tune, buy a management system and put it on your daily driver. That's what I did. You can't expect anyone to hand over their engine/car and just let you go at it without any first-hand experience (or if they do, they're not too wise themselves).

Or take a class like EFI101 for a taste of hands-on tuning. (Ben Strader also has a decent book)

THEN, once you know what you're talking about and you have specific questions about something, you can use forums like this for direction.

And that's the best advice I can give.

 

i read the pgmfi.org day and night i do ok now

 

reading is good but practice on a mild/stock motor to get the feel of it and how the small changes effect the operation of the engine.

if you have no idea what you are doing, i wouldnt touch an ecu.

i would recommend reading as much as you can first. yes this wont teach you exactly how to tune, but it will lay a foundation. trial and error with an engine isnt the smartest route.

then find a buddy or someone local that will show you a few things on their car. regardless if they are tuned or not, they can still show you different maps and how different adjustments affect the overall tune. or find a buddy or local that will ride along with you and use your car as the prop.

one thing is for sure, if you are going to street tune, it would be wise to have 2 people in the car (1 to drive, the other to tune).

if you are friendless, then you can possibly dick around on your car as long as you make only minor adjustments so you dont damage your engine.

my 2 cents...

 

I didn't know what i was doing and i manage to do really good withing the first day.. is all about getting the concept and understanding how the map works. I remember spending 800 bucks worth of ****, LM-1, innovate RPM converter with the inductive clamp, even an egt probe.. i remember the first time i went out i use to wire all that BS into the car (like 45min worth or wiring) before i learned u could dattalog right off the factory ecu.

if you really want to learn just get a wideband, USB dattalogging cable for the ecu with crome and freelog, software is free, usb cable 25 bucks, and the wideband probable 150-300, or DIY.. make your self an electronic DET CAN (google it up).

go on the street on a bone stock car and just dattalog with freelog, learn how the pedal influences where the ecu reads on the map, ones you grasped that concept make changes to the fuel.. just a bit and see how it changes. go to a straight road with no traffic and do some WOT 3rd gear pulls and smooth your fuel, for the ignition there is not too much you could do in the street, i just advance till the butt dyno shows no improvement or till i hear knocking on the cans.

ones you learn how to manipulate the map you should start searching how to use the other functions like battery offset, fuel multipliers, acc enrichment and **** like that, there is no need to mess with non of that on a stock car.

 

LMFAO I did the same thing.......Haaa

 

thats good advice and that's my plan for my 90 accord im gonna turbo and learn to tune with neptune i hear its the most user friendly and the creator is always on the forum and answers questions promptly...
