As you may know, your DTA supports an external controller that allows you to quickly and efficiently map the ECU using a series of knobs and buttons. Here are the schematics for creating both a HD15 -> DB9 serial tuning cable (straight thru) as well as the HD15 -> Dyno Box w/ DB9 pass thru (for hooking up laptop at the same time, which you want).
And here is an example of what your DB15 to serial cable may look like:
here is an example of what the dyno box might look like:

Re: DTA Dyno Box -- Schematics and Pictures
yes, normal 270 degree ones, 4.7K or 10K is ideal, must be "linear" not "Log" ones, also remember that the switches are "break" not "make", very important!razzor wrote:the pots used are they the continuos type or 360 degree ?

And not forgetting as per DTA's pinout schedule that flash programming switch goes between pin 8 and 13 of the 15pin connector.

Re: DTA Dyno Box -- Schematics and Pictures
the flash programming button must it be a n/o or n/c button ?
