Sales Inquiries

If you have questions about ordering (do you ship to my country, do you offer quantity discounts, etc.), have you looked at our ordering faqs page?
Although we generally cater to the small purchaser, we wouldn’t want to pass up any opportunities to ship larger volumes! If you have any inquiries as to large volume shipments then write to us at this address.


We are always interested in improving our products (and our web site). If you would like to comment on either, or provide feedback on your order, just drop us a line at this address.

Tech Support

Before writing – are you looking for construction or troubleshooting tips, or possibly Application Notes? Then visit our help pages. Have an OBD specific question (for construction or troubleshooting tips, software, etc.)? Then visit the OBD specific help pages.
Can’t see an answer to your technical problem? We may be able to help, if you send an email describing the problem and telling us what you have a done so far. We try to respond the same day, if we can.

We do not post our telephone numbers, as time zone differences throughout the world have only proven to cause problems. Our apologies.
