Some have very limited bi-directional like IAC actuation and such but in no way reprogram or flash.
MDI or Mongoose interfaces are available for about 300-600$ but wait til you see the price of the software.
Look around in the automotive products forum further, you will see I did extensive research and gave out way to may links to count. Read through them. You may find what suits your needs.
Something like this will cost you around 1500$ once upgrades are done. Look to bottom of the links page to give you an idea of what I am saying. You absolutely need a J2534 interface to have true bi-directional control.
The others only give partial. http://www.scantool.net/ No miracles in these. I use em for basic stuff with my laptop and just use the parameters to diagnose. I will never in my wildest dreams think I can reflash with these.
http://www.drewtech.com/products/mongoose.html Now, don't forget, you need software.
http://www.cardiag.co.uk/latest-high-quality-gm-mdi-multiple-diagnostic-interface.html Now don't forget the software.
Thanks Nickb2! I guess I should have been a little more clear. I don't want to reprogram/flash, just to be able to adjust shift points in transmission, adjust TPM pressure, turn on/off the switches/lights that the ecm normally controls!
I did effectively not know what you meant in that case. For that, you just won't find that for cheap. Sorry, still gotta go high end for what you want.
I think what you want is a tuner scan tool. Something like this. http://www.efilive.com/product-info-efilive-tuning-tool Here is another for mapping software http://www.viezu.com/ Model specific.
Now these types of tools are package normally by manufacturer and will only do one model in a certain year point. Ex, a dodge cummins kit, or a ford power stroke kit etc. http://www.efilive.com/flashscan
Even a high end scanner normally won't let you modify shift points and such. Did you want a tool that could do all makes? Cuz that ain't gonna happen. Probably never will. Now getting software that does mapping and such is high level skill galore that even I can't do. You only see that in fast and furious.
You need to learn code and such. This can be done with a simple elm protocal with some HEAVY modification of said car to just communicate with said module and change values yourself. Now what are those values? Mostly hidden by the programers that wrote the code.
Vw is easy to tune. With a VAG protocal their codes are easy to find and change with proper software. I will post an example of what I mean for elm. http://theksmith.com/technology/hack-vehicle-bus-cheap-easy-part-1/ See step 3 of the article. So in essence it would days of programming your dash to say hi when you put the key in for example. That is why these kits are so expensive because programers have spent years on just one type of transmission for example. A life works of sorts that involve years and teams to develop. So unless your willing to go to university for this, I suggest a tuner kit.
I want to know what you want to do and for what vehicle if you care to share.
Someone who want to do their own mapping needs to modify the eprom or get an ECU that is modified for this. These are race applications and cost thousands just for one car.
Anyway, I am getting ahead of myself. Have delved a bit into this myself but not a passion so I am not too savy.
Some automatics come equipped with a "manual mode" that you can use to choose shift points. My 2009 Santa Fe has it. My wife gets upset if I use it because she thinks it is "her car" and she thinks I'm going to hurt it if it doesn't shift the way she is used to.
Range Selection Mode
The vehicle may have a Range
Selection Mode. The Range
Selection Mode helps control the
vehicle's transmission and vehicle
speed while driving down hill or
towing a trailer by letting you select
a desired range of gears.
To use this feature, do the following:
1. Move the shift lever to
M (Manual Mode).
2. Press the plus/minus buttons,
located on the steering column
shift lever, to select the desired
range of gears for current driving
When M (Manual Mode) is selected
a number displays next to the M,
indicating the current gear.
This number is the highest gear
that can be used. However, the
vehicle can automatically shift to
lower gears as it adjusts to driving
conditions. This means that all
gears below that number are
available. When 5 (Fifth) is selected,
1 (First) through 5 (Fifth) gears are
automatically shifted by the vehicle,
but 6 (Sixth) cannot be used until
the plus/minus button located on the
steering column lever is used to
change to the gear.
