What do you want to do with it? Are you just going to load a generic map, learn how to tune yourself, datalog? Don't sit in your car to long, I heard it's cold in TX today.

There is no such thing as a "generic" map. They are all specific to a year and stage of mods.

If by generic you mean open source map, you should start by logging your car's performance and understanding the map that already exists on it before you flash ANY map to it. Too many people are flashing maps without really understanding what they are doing.

I'm not trying to speak gloom and doom here, just a little wisdom.

We are all here to help though

He means generic staged maps.

Tell us what mods you have and we can tell you what stg map you need.

Alright done all that and can't figure out how to flash my car computer. Hooked up the cable to car and connected the two green plugs and the jumper. What next?

Use ECUFlash to flash to the ecu

btw, You should read this before you screw something up,

definitely start with datalogging first. Save the map on the ECU now to a rom file on your computer and just look at it. Start to learn what everything does and how changes effect them before you start making changes.

You know, if you post in the local forums, you might find someone local to you that has done some of this. But then Houston is such a small town...

Make sure your laptop recognizes the cable. If not, you will not be able to do anything in ECUFlash. When you boot the program, if the "Read from ECU" icon is highlighted, then your are connected. Sometimes laptops don't like the cable being pullged in while they are booted. Plug it in first and then boot.

really?? you sure about that? (hint, there are OS drivers for EVERY piece of hardware connected to a computer, unless it is handled by the underlying bios in some cases. (older style keyboards for example) I've written drivers for a couple different pieces of custom equipment, writing drivers sucks!


anyway, there ARE drivers, and they are a little touchy in fact.

The drivers for the cable are in the ECUFlash software.

Sounds like you got the connection right. Can you log data from your car? Before you get all gung-ho, I recommend that you get familiar with the way your car works right now. Understand what you're looking at and how it works before you start flashing maps doing pulls. I have seen people posting logs that showed slight issues on cars that were just running OTS maps. The problem was that the owners of the cars did not understand enough to be able to spot problems in the logs. Here is what you should know before you start flashing and tuning your car:

1. How to open and view and modify maps
2. How to log the car with meaningful data. Logging ALL data is not the answer.
3. How does boost control system work? What are wastegate duty cycles? What are boost targets? Which maps control which parameter?
4. How does fueling work? What is AFR? What does lean and rich mean? How does fueling effect EGTs? Which map controls the fueling?
5. What is ignition timing? How does it effect the performance of the car? How is timing related to EGTs? Which map controls timing?
6. How is each map interpreted by the ECU? What do the x and y axis mean?

Read these questions and see if you know the answers. If you don't know what I am talking about, you need to do some reading. Do the research, log the car, see if you understand how things work and go from there. Feel free to ask specific questions and we'll be happy to help out. Your original question was not specific and as you can see, you got a bunch of vague answers because we're all trying to figure out what you're trying to do. Good luck

BTW, the list I posted is just the start but it will point you in the right direction. Once you know where you want to be and what to do, it'll get easier and you'll see the light.

Who needs brakes?

I ordered a cable - I'm pretty excited to start watching what is going on in there.

It'll let me put my engineering brain to work on something besides brakes.

?? for Ziggy - is a wideband 02 sensor and or high quality EGT guage worth it? At some point the VF-39 is either to get ported or replaced so I want to be prepared for self tuning. At least that is the goal which I only have moderate doubts about.

I think they are worth it if you can get a good deal on them. An EGT gauge is a safety net which will tell you if you're heading for trouble. I like to have it to know how things are running. Some get away with tuning without one. I feel that $100 (prosport EGT) is not that much to pay for added safety.

WBO2 is extremely helpful to really nail the fueling, especially if you are getting ethanol in your gas, like I do. I do not have one currently but I am planning to obtain one shortly to verify my fueling is on the mark. You can find LC-1 from Innovate for under $200.

I always say that you need right tools for the job. I think you'll be much more effective with them

Zig, awesome post. Hopefully people will read and decide to take the time to understande before flashing any map.
