This is a top quality, plug and play flex fuel kit. It taps into your coil pack for power and the white wire is connected to the ECM connector x1, pin #38. Use this kit to add the ability to run anywhere from straight gasoline to straight ethanol* as well as reveal the true power potential of your setup. Forced induction scenarios especially benefit from the use of ethanol, and these allow you to seamlessly switch between gasoline and ethanol without having to monitor your fuel content or reflash your tune.
This kit uses:
- Genuine GM Flex Fuel sensor
- Plumbing kit made of corrosion resistant materials to ease installation
- Plug and Play wiring harness made with OEM connectors and terminals crimped with OEM tooling
- DSX Tuning 3D printed fuel line disconnect
PLEASE NOTE: It is possible to install this kit without tuning, but you will not gain the ability to switch fuels until the functionality is activated via custom tuning.
DSX Warranty: DSX manufactured components are covered against defects in materials and workmanship for the life of the product.
* In order to run flex fuel on an ATS-V, the following items are required. These will provide enough fuel volume to support ~ E30 to E50 fuel (depending on boost ramp).
- Tapout Stage 1 LPFP
- Tapout fuel cam
- Tapout remote tune
- Monthly tuning subscription
- Wideband oxygen sensor
- DSX Tuning flex fuel kit
What fuel system mods are required to run E85?
it depends on how much boost you are targeting and how high of ethanol content you would like to run.
Some people claim that you can run E30 on the stock fuel system. However, this is a dangerous and misleading statement. We have repaired and/or replaced many engines for people who trusted that negligent advice.
Although the stock fuel system can technically handle E30, you will be required to reduce boost down to the point that you won’t make any more power than you could have on pump gas. With our Stage 1 LPFP, fuel cam and alcohol content sensor you can typically run ~ E47 without issue. This is convenient mix of half pump gas and half pump E85.
If you add on the AutoTech HPFP internals, you can run up to straight E85 at reasonable boost levels. With the stock or Turbobay turbos turned all the way up on a Kill Tune, you should be safe somewhere in the E60 to E70 range.
For those stepping up to Caddy Issues turbos, you will need to upgrade to the Stage 2 OG Solutions LPFP, and/or add methanol injection.
