I'm an engineer at DrewTech and work on the Mongoose cable. It depends completely upon the software you're using.
Most ECUs artifically limit the Mode 1-9 OBD responses to max 30/sec. If you're using DMRs or rapid packet modes, you can expect 150-200 frames per second on most GM and Ford controllers. Since Mongoose supports full bandwidth it will give the highest rates supported by your software. I'm programming on a plug-in library right now that'll allow highspeed datalogging in any/all software.
I've got an ELM5 and could run a comparison benchmark if necessary. The serial pipe is going to saturate pretty quickly.
Mongoose seems to be my reader of choice from the research I am doing. I am looking for something that will return 1-2 bits of data as often as possible. Probably something like 10+ samples a second. So mongoose seems like a good choice. FYI, I will be using the Asian/Euro module for mongoose.
Do you have any program samples/API Docs or naything of that nature to aid me for when I start developing my app? The app will most likly be written in C#, but any/all example will be greatly appreciated.
The formal SAE J2534 API specification is available straight from the SAE for around $50. I've written an overview (http://www.drewtech.com/support/j2534/) that may be helpful in the meantime. Sample code is available upon request for both C and C#.
