Home of the JB4 the worlds most popular turbocharged tuning system! If you prefer to make adjustment by engine speed duty bias can also be adjusted up and down to provide a similar effect. The default setting of 50 can be incremented in values of 5 as desired. Setting boost reduction 1st (called max boost 1st in older interfaces) to 3psi will reduce the JB4 boost target by 3psi in 1st gear when launching.įor those who have installed the optional EWG connection FF can be used to scale up and down WGDC to drive boost up to target. For those running pump gas and the factory intake, the default setting of 0 is fine.įor those who want to reduce wear and tear when launching boost by gear can be enabled. Going too high will trigger false alarm fuel pressure codes. A higher level increases fuel pressure and lowers fuel trims. Open loop is used to adjust the fuel trims by altering the fuel pressure reading. Open loop can be set to 30 by those running E85 mixtures and/or aftermarket intakes. Note with v6 and newer firmware, default fuel bias settings are 80 across the board, and levels below 50 provide a "negative" offset giving additional tuning flexibility that was not possible in earlier firmware. If needed you can lower across the board in increments of 10-20 until AFR at full throttle, higher RPM, is in the 12s. For those with aftermarket intake systems sometimes fuel bias needs to be lowered to richen the air/fuel ratio. Map7: Progressive WMI mapping, under developmentįuel bias is used to adjust the MAF offset which impacts both the air/fuel ratio and peak timing advance. Map6: User adjustable by RPM map on user adjustment page, values are peak boost over stock by RPM under heavy throttle. Map5: +7psi peak, no boost taper, more aggressive version of map4. Map4: +7psi peak, suggested for 30% E85 along with bolt on modifications Map2: +4psi peak, suggested for 93 octane or higher Map1: +3psi peak over stock, default map, suitable for all fuels.
