Let’s compare to the other three best known systems out there.
What makes NepTune a better option than S300? NepTune has more usable features and comparable features that exceed the configurability of a S300 (Like Anti-Theft, Up to 12 hours of on board logging with better start and stop parameters, access to more ignition corrections and the ability to disable corrections completely, and live graphing just to name a few) at a much lower price because we don’t have as much overhead. We don’t sacrifice quality because we have a lower price either… In fact everything is thoroughly tested and stable before being released to the public and updates to improve usability occur regularly. NepTune offers the best support in the industry, and we’ll make sure you have the best experience possible with our system.
What makes NepTune a better option than Crome? The list of features NepTune has that Crome does not is endless, and at $44 more than a Crome Pro Tuning Package (Ostrich-$175, Hulog-$30, and Crome Pro-$150) it’s worth it! Complete ignition control, better datalogging, datalog graphing, live graphing, PWM boost control, Anti-Theft, and a huge list of other features can really make the difference when it comes to tuning a vehicle. Best of all our features work properly so you won’t struggle with tracking down bugs.
What makes NepTune a better option than eCtune? While NepTune and eCtune have a very comparable price and feature list (They have a few we don’t have… and we have a few they don’t have yet, like Anti-Theft, on board logging, and proper closed loop wideband support), NepTune has been around longer and is more thoroughly tested before releases. Best of all it shows. NepTune’s features are rock solid, our support is second to none, and our support forum is not constantly full of bug reports. We also don’t force you to update your software if you’re happy with the current version.
