JTech Amarok Flash Tune - Fixing the Auto Reverse Issue
This Video was shot at Salt Creek, Coorong SA to show the problem that torque limiting creates on a VW Amarok TDI420 Auto.
All Amaroks with the 8-speed Automatic Transmission suffer from this issue. The vehicle in this video is a 2015 Highline. Older models are much worse. At J-Tech Automotive Enhancements, we are able to remove this limitation, as well as giving you more Torque, better power, and substantially reducing your fuel consumption
Thanks for watching!

**Update**
At the time of shooting this video we were using a product from Crispmods. As it was an early release product that could have been developed better, as soon as we stopped using crispmods we contacted every single customer that we had tuned their vehicle using a Crispmods file, and custom tuned them using our Australian software engineer. This was at our cost, and although we spent thousands of dollars doing this, the end result was that all our customers now had a much higher quality product with safety, reliability and guaranteed longevity. We have so much faith in our product that all customers vehicles that were re-tuned now have a 2 year unlimited kilometre warranty. The main issue was that we thought we were getting an Aussie product, and myself and others were led to believe that the owner of Crispmods was a software engineer, and was writing his own files. Unfortunately, it turns out that he was not a software engineer, and was just reselling files purchased from Sweden. This was all well and good, apart from the fact that the tunes could have been developed better as they were quite often running too rich, and not as suited to Australian conditions as they could be.
In addition to this, myself and others were led to believe that the auto reverse issue in the Amarok’s was based on a “per gear” torque limiter.
It turns out that although the ecu in the Amarok’s feature torque based architecture (ie with torque limiters), it is not based on a “per gear” scenario.
I apologise if you were misled by this misinformation - it was what we were told and subsequently what we believed.
However at the end of the day the end result is still the same. A stock amarok still has reverse limitations that can be overcome with an ECU Remap.
It turns out, that the real issue is because of the heavy duty torque converter, as well as the gear ratios.
As the torque converter is so heavy duty, a stock Amarok doesn’t make enough torque to get the torque to enter its “coupling” phase, and effectively transfer enough torque to the wheels.
This can be altered with an ecu remap, by raising the torque limits, injection timing, injection quantity and “drivers wish” maps among others.
