What's wrong with my hole?

Steve please comment and make sure I got it right per your description in the thread above, and make changes where needed

Great job, only one issue. on a male DB9 connector the pins are numbered right to left. They are left to right on a female connector.

As far as "You dont need the rs232 circuit below (From MMCds website) with a Palm or anything with a rs 232 serial interface built-in." Thats just wrong. I know your just trying to same and active interface isn't required but it's the fact that newer RS-232 interface chips like the ones used in battery operated devices like PDA's and laptops are far more forgiving than the standard requires that makes the passive interface work. The data signal to and from the ECU is 0 to +12 volt swings. The spec requires negative voltage swings of -3v to -25v with respect to signal ground to be considered logic '1' (the marking condition) and voltages of +3v to +25v are considered logic '0' (the spacing condition). The passive interface can't generate these negative voltage signals, it can only go to ground. The active interface uses the same type of chip with charge pumps to generate standard compliant voltages, both positive and negative, so that it works with any serial device that supports the ECU's data rate.

Not hijacking, but could someone send me the PocketLogger software? I'm getting a used cable and PDA with my Talon but he doesn't have the software (he bought if off eBay).

Hit me up on AIM at e30matt or email me at [email protected]

Can't help you with a bootleg copy of Digital Tuners Pocketlogger software but you might want to try MMCd since it's freely available.

Im going to turn the diode around,solder all the connections,and see what happens.You guys are very helpful.Bosljeff and I took the bullet on this one.

We don't support piracy here.

If somone bought a pocketlogger from ebay there is still a a way to get in transferred into your name.

check out www.pocketlogger.com for the details.

I edited the pic for everyone but left the db9 male connector since it seems most of the cheap Ebay and homemade cables you get have a male connector. The one I got for $20 from a guy here at Tuners came with a male connector. No biggie you guys can just get a slimline db9 female to female gender changer to plug your logger cable into your hotsync cable. Radio shack has em for a couple bucks.

I switched the diode around.I didnt get serial comm error this time,I got ecu comm error.So I said f*ck it,went to radio shack and got 10k ohm resistors,and the right diodes and a new male connector.Made it exactly how talonmans diagram is.Went to the car with mixed feeling about it,plugged it in,started the car,IT WORKS!!!!.Thanks steve and talonman.The diagram helped alot.

Congratz, you now know more than the Richard Cranium that sold it to you.
