What is a JB4 piggyback tune?
We must diverge for another brief moment to discuss the setup we recommend above all else – stacking the JB4 piggyback tune with an MHD BEF. The JB4 is loaded with unique features that come with the tune at no extra cost. It allows for steering wheel controls to change maps on the fly within seconds. A great option for those who may want a modest DD tune with the ability to crank thinks into kill mode in a second. It allows for gauge hi-jacking to display boost, AFR’s, ignition timing, etc on the fuel and/or oil temperature gauges. Additionally, the JB4 allows data-logging capabilities without the need to purchase the $69 MHD data-logging feature. You can limit boost by gear for 1st, 2nd, and 3rd gears. These are just a few features worth mentioning. We’re not done yet.
What is flash tune?
Flash tunes essentially re-write the ECU/DME to target more aggressive boost. Flashing the DME also gives the tune full control over fueling, ignition timing, AFR’s, etc. This is a major benefit of flash tunes as opposed to piggyback tunes, such as the JB4.
Do E50 maps require mods?
These maps do not require any supporting mods, unless opting for the E50 maps which requires an upgraded low-pressure fuel pump (LPFP). However, due to the increased airflow we recommend upgrading to dual cone intakes (DCI). If not for the slight bump in power, this $80 mod is worth it for the looks and sound alone.
Is stage 1+ a good mod?
You can get by on the stock FMIC, but the tune will pull timing as IAT’s get too high. An FMIC is a great mod to have, nonetheless. While peak horsepower on glory runs may not see a huge increase, upgraded FMIC’s help with consistency.
Does the JB4 have a flash tune?
These are safety features worth having that flash tunes simply do not have. In summary, the JB4 when coupled with a back-end flash tune retains its advanced boost control, user-friendly features, and safety features. However, the MHD flash tune is given full control of AFR’s, timing, fueling, etc.
