Just bought a utec, need to start a hunt for maps that match my mods.

1. UR pulley set
2. MD 5/16 spacer
3. injen CAI

I will need to coaching to start understanding this utec tuning.

I have a laptop that i will be able to use with the utec to tune. Also have good understanding of computers.

Yet tuning is something entirely foreign to me. ANY help would be great guys. Thanks.

 

Here you go, this is a thread about sharing UTEC Maps:

First, did you buy the tuner wideband? If not, then you need some method of logging your a/f's in realtime.

Second, spend some time in the Tuning section at my350z. A lot of information and resources there. Here's the link: http://www.my350z.com/forum/forumdisplay.php?f=448

 

A/F? Don't know what that is....

 

Air/Fuel ratios. The stock ecu will tend to run lean in closed loop, for maximum fuel efficiency and to reduce emissions. In open loop, it will run richer, especially as the engine approaches redline. It's typically in the neighborhood of 12.0:1.

These engines make most power right around 13.0:1 or 13.1:1. In order to achieve that target, you must know by how much you wish to offset the MAF signal to the stock ecu. In order to know that, you must have some way of determining your current a/f's at the various load points. That means you either use a wideband like the Turbo XS Tuner Wideband, you dyno-tune it, or you use a tool like Cipher to datalog the factory widebands if your car is an 04.5 or newer.

 

Then you're not even ready to do any kind of tuning. Go to a shop and let them do it then read some book about tuning and how they work in general before you jump in.

 

well thank you for the help.

 

If you're interested in doing some minor tuning then you can buy this book.

How to Tune and Modify Engine Management Systems by Jeff Hartman

also a good reference for FI is Maximum Boost by Corky Bell.

 

ya i wouldnt mess with it if you dont know whatyou are doing for best results you shoulod take it to someone that knows all the tricks
