Things to know BEFORE buying a TwEECer or Quarterhorse

When I first bought my TwEECer, I expected it to be much more intuitive than it was. From the get-go, I was frustrated with the accompanying software's buggyness (CalEdit & CalCon) and that there are no tools included with the TwEECer to help you make heads or tails of your datalogs. I got the TwEECer, I got it working, and I ended up with datalog files that don't seem to open in any standard editor or database manager. After spending $550+ on a new TwEECerRT, I get hit with being told by other owners that I need to buy more software if I want to do anything with those logs. The other option is mess around with people's 1/2 baked Excel programs that have nearly no documentation.
I eventually figured out all the ins and outs of tuning with the TwEECer, and later made a seamless migration to using the Moates Quarterhorse since it is newer, cheaper, and in my opinion, all-around better than the TwEECer RT. Here is my collection of knowledge that I wish I'd known BEFORE I bought a TwEECer. Note, many of the comments also apply to those considering a Quarterhorse, but the comments made relating to CalEdit/CalCon are specific to the TwEECer since CalEdit/Calcon don't support the Moates Quarterhorse. For more info on the difference between the TwEECer and Quarterhorse, there's a detailed comparison in the FAQ for reference.
- Don't mess with the TwEECer base. It's the TwEECer RT or something non-TwEECer. The power of the TwEECer is not in its ability to tune the EEC. There are plenty of other products like Moates and SCT chips that can do that for cheaper than the TwEECer base. The power of the TwEECer RT is its ability to datalog the EEC.
- When you buy a TwEECer RT, expect to purchase EEC Analyzer. It will open and analyze the datalog files that are a result of the TwEECer datalogging your engine's behavior during a run/drive. The bread-n-butter of EEC Analyzer is to help you sort out your MAF curve. It also helps with tuning a number of other aspects of the EEC and for advanced users, it will display maps and charts of the various things you datalogged across the Load/RPM range. Expect to pay ~$70 to register EEC Analyzer. Click here to read more about EEC Analyzer:
