Hey guys,

I'm a DIY-er and I would like to learn tuning/mapping myself.

Where do I start?

Thnx

 

Google.

 

UTI...lol

 

never mind, i just ordered a couple of books on the subject.

 

You could read the many guides out there for Opensource and RomRaider. They're for Subarus, but it's a good beginning point. I'm beginning to tune my own WRX. Not difficult at all once you understand everything and can live with the fact that road tuning your own car will take a LOT more time... as you need to find that perfect spot. Start out rich, and lean it out as much as you feel comfortable with.

 

My advise is to be wary of information you read on the internet. There are many backyard t00ners spouting incorrect, even dangerous misinformation.

These books are a good starting point-



Also, check out efi101.com. Lots of great tuners hang out there and share info.

 

I have this first book, its a good book, very easy to read.

 

thnx guys i've ordered both books.

 

Lol i made an exact post like chris over a year ago with the first book. Good read to understand whats going on. It obviously helps if you have some wrench/diagnostic experience or what have you. Tuning fuel is simple. The rest is going to be hard to justify without a dyno. Timing, cam timing, etc...

But I like seeing posts like this, hopefully we can eventually be like other forums that have tons of info to share

 

yeah, I've read that book as well. Pretty good stuff. You could also pick up Maximum Boost and Auto Math.

 

Ditto. I have the two listed and Maximum Boost. Awesome resources!

 

received my books yesterday and i'm halfway through How totune and modify engine management systems... already learned tons of good stuff! (:

 

If you are planning to do any MAP based tuning, I would also highly recommend the other book by Greg Banish called "Designing and Tuning High Performance Fuel Injection Systems".

In my experience, I would have saved myself from hundreds of hours of reading and a lot of false information if I had read these books years ago.

 

that is good to hear because i've bought that book too (:

right now i've read two books already and the more i read the more i feel i can do this.

 

The toughest part is going to be the learning curves of the different software. Some systems are easy to use and some are a bit tougher.

On newer cars you aren't likely to use a Megasquirt, but a lot of the information there is involving tuning theory and different corrections that exist in just about any stand-alone.

that's where I learned quite a bit before diving into my own Uprev F/I tuning... by reading the megasquirt stuff haha. Everything else I kinda of learned as I went... there isn't a whole lot to mess with on Uprev. For example, there are zero temp correction functions...kind of scary but it is what it is.

 

I'm sure they will get there eventually. I guess you just have to have winter/summer maps. I'll be tuning a Megasquirted 280Z hopefully monday!

 

thnx for the link, i will have a look.

i'm going for the haltech platinum pro.

my plan is to first install the haltech, gauges, injectors and walbro fuel pump and mess around a bit trying to get everything running good and get familiar with the software and the basics of tuning. i might also get a g-tech pro rr and try if that is a useful tuning tool like Jeff Hartman states in his book.

the when i feel i'm ready for real mapping and tuning i will install my vortech supercharger and the fun can begin.

 

I think so... now that it's colder I started throwing P0420/ect...so I started datalogging and had to pull about 15-20% fuel across the board now that winter is kicking in. So temp comps are definitely 'working'... just way too much...
