Product Spotligh Product Spotlight: If you have an Interro PDA 2000 or later you can now use it as a CAN-compatible Generic OBD-ii scan tool. All you need is Omitec Interro's new PDAscan Kit. Supports all current OBD-II protocols and CAN (Controller Area Network) and delivers all nine of the J1979 E/E diagnostic test mode functions (e.g., I/M Readiness, read "hard" and "pending" codes, erase codes, view the live datastream, freeze frame data and on-board systems tests, and more). Plug the PDAScan PCMCIA
software card into your PDA unit. Then connect PDAScan's OmiConnect
cable to the PDA unit and to the vehicle's OBD-II connector and turn on
the PDA unit. Scan away.
Kevin Ramsey, Worldwide Product Manager, states that

is coming soon. "Like all the accessories that Omitec

Technical Article: Why are Distributor-less ignition patterns difficult to acquire? Mac Vandenbrink has some answers to this question and has proposed a solution in his 22-page operator's manual for his soon-to-be-released product: “The FIRE-BOX” Here is an introduction from Mac: DIS has always given an unstable scope pattern because it has no reference to ground like any other ignition system. This not only causes the KV readings to fluctuate, but it also affects the rest of the pattern with inconsistent waveforms. It is tolerable when the vehicle has no problem, but when the difference between waste and compression increases, the zero offset acts like a yoyo, Some of the more sophisticated scopes use a filter or use a voltage averaging. (Both have drawbacks). Lab-Scopes don’t even have that luxury. Hypothetically, if the coil would have been center-tapped to ground, the scope would be happy as a Lark. Since the scope uses ground as a reference point, but the ignition system uses the motor-block only as a conductor, which is not center between the coil towers, the waveform will vary from stroke to stroke and you will seldom see the same waveform twice. Read the booklet to learn about Mac's solution and to get some hints and techniques for dealing with DIS problems. This booklet is heavily illustrated and to keep file size down we split it into 3 PDF files but it may still take a while to download.
