1)  Power Tech Spring Tester Retrofit Kits   Several customers have contacted up regarding their Power Tech Valve Spring Tester.  Our info is they are out of business, so there is no longer any support for their software, electronics, or hardware.  If you can wire up and calibrate the length sensor and load cell, you can switch over to our electronics and software for as little as $499, or $599 with the popular Plus version of our software.  

Or, if you can send in your Power Tech (and even your laptop), we can do everything (install connectors, calibrate the load cell and length sensor, install and unlock software, etc) for an additional charge.  Then you would receive back your valve spring tester and computer, ready to start testing.

to send us an email requesting info on our Power Tech Retrofit Kit.


2)  New Video Showing Spring Tester Calibration   We've made a Video showing how to calibrate the length sensor on a valve spring tester.  This was made specifically because of the interest customers had in installing the Power Tech Retrofit Kit themselves and then doing the calibration.

3)  PRI Trade Show, Indianapolis, Coming in December   We're exhibiting at the Best and Biggest racing products trade show in the world, the Performance Racing Industry trade show in Indianapolis, Dec 8-10.  We're in the same location as last year, booth # 134, so check their website floor plan, and be sure to register to attend ahead of time.

4) Christmas is Coming  Just a reminder that Christmas will be here in less than 2 months.  If you've been thinking of getting one of our products, put it on your Christmas list.     Maybe Santa will be extra good to you this year (as long as you've been nice  ).  


5)  Many New FAQ Answers on our Website  We've added answers to several new Frequently Asked Questions various customers have asked over the past few months.  Even if you don't have a particular question, the FAQ page is a wealth of knowledge about all our products.  Many times it will show details on the most recent features of a product that are not contained in the User's Manual.  We really recommend you take a look.

6)  Engine Analyzer Pro v3.9 B, More Head Files  We've added about 40 more example head files to our Engine Analyzer Pro v3.9B.  These files are part of a free update to those who own v3.9 B, which was released in August 2016.  There has also been a couple of minor bug fixes.  The latest version is now v3.9 B.013.

For those of you who missed last month's newsletter, we talked about how we've been working a long time on one of our most popular programs, the Engine Analyzer Pro.  It is now up to v3.9 B for both the standard Pro and more advanced Enterprise Edition.
