Going with ECU tune, no longer need JB4. $650 Shipped within the US by priority mail. Updated to latest 3.13 Firmware. Current setup is Stage 3. Free install if you're local.
Code:
Map 0: Disable JB4 / Full Pass Through Mode
Map 1: Stage1 map adding approximately 40whp and 40wtq across the power band on pump gas. Suitable for all stages and fuel mixtures.
Map 2: Slightly more aggressive version of map 1 intended for vehicles with exhaust modifications and 93+ octane fuel. Can also be used with E85 and racing fuel mixtures. Requires Stage2. Stage3 fuel connector suggested.
Map 3: Slightly less aggressive version of map 1 intended for vehicles running on lower grade fuels such as 91 octane. Requires Stage2.
Map 4: OEM performance but with JB4 active for datalogging only.
Map 5: //M low torque (evaluation) map.
Map 6: Custom tuning map.
Map 7: Race gas map. Requires 100 octane unleaded fuel and for the fuel mass connector to be installed. Can be used with or without the EWG connectors but will make more power with the EWG connectors installed. This map can also be used with up to 35% E85 but in some vehicles & conditions this may cause a high fuel pressure drop and resulting stuttering. If this occurs drop down to map 2.
Map 8: Methanol Injection map. Requires BMS FSB controller or methanol kit for progressive mapping and safety systems. For pump gas a meth additive of 30 is suggested while for race gas/E85 + meth up to a 75 additive can be used. The higher the meth additive the more aggressive the boost curve. A meth additive of 60 would be roughly equivalent to map 7.
Note: For race use only to enable the automatic clearing of passive codes (real codes will continue to show a light in dash) set FutureUseD = 90.
E85 Mixtures:
We've done limited testing with E85 mixtures and found that the platform seems to be largely tolerant to up to 4-5 gallons of E85 per full tank of pump gas. Higher mixtures normally result in fuel trims maxing out and engine stuttering or misfiring. Raising "open loop" from the default value of 60 to 70 can help allow a bit more power on E85 but may also increase the likelihood of a "fuel pressure too low" fault code. We suggest map 2 for E85 mixtures as it offers the best all around compromise of power and reliability with it. The Stage3 fuel connector is required for any E85 mixture.
Firmware v3.13
1) Revised map switch indicator per latest video below.
Firmware v3.12
1) Increased data sampling rate.
2) Adjusted AFR to show a blended bank1/bank2 value. I will separate them again down the road as we have more logging changes in the works.
3) Added user adjustable "3rd gear" boost limiter. Requires new interface. Note that 1st gear reduces boost by that amount below 30mph, 2nd gear reduces boost by that amount below 50mph, an 3rd gear reduces boost by that amount below 85mph. If dyno testing you should set these values to 0 otherwise they will lower boost for parts of your dyno runs. We will be implementing a gear logging system (computed using road speed and RPM) in a future release.
Firmware v3.11
1) Changed map switch indicator per new video. This new method works the same with both automatic and manual vehicles.
2) Added additional maps for use with PURE S2 turbos. If installing these turbos email us for directions on how to enable the maps.
Firmware v3.10
1) Modified CAN Flap operation per DEMO Video #3.
2) v3.10a removed trans flash option during CANflap change. A couple users reported it caused the car to shift to neutral when engaged. We're working on a better dash indicator for the CANflap operation.
Firmware v3.9
1) Added various meth integration and large turbo programming.
2) Setup logging so that any time PC is connected and logging started CANbus logging is active.
3) Added CAN Flap feature per DEMO Video below.
Firmware v3.6
1) Added new map changing programming shown in video.
Firmware v3.5
1) Enabled the desperately needed torque limiting for launching. Although the field is labeled "max boost 1st & 2nd" it's actually "boost reduction 30mph & 50mph". As shown here these settings lower boost by 5psi under 30mph and 3psi under 50mph. The actual values can be fine tuned for your particular tires, track, and situation. But this has been working well for us so far during testing.
2) Added second bank AFR logging under the AFR2 channel allowing both banks to be monitored independently.
3) Added fuel trim logging under "trims".
4) Added road speed logging as MPH under the "I Avg" parameter. We'll give it a better home soon.
5) Added low fuel pressure monitoring under "FP L". Expect to see around 72psi under normal circumstances. FYI when testing higher amounts of E85 we've found high pressure drops before low pressure drops indicating no immediate need for low pressure pump upgrades in this platform.
6) Maps 1-5 are additive maps meaning boost is added to the stock curve. While maps 6-8 are absolute targeting maps meaning the target is largely independent of the OEM boost target. For maps 1-5 we adjusted the logging such that the target parameter now reflects the additive boost.
7) By popular demand, we've started work on an //M map, which will be under map 5. The idea behind this map is to simulate an naturally aspirated vehicle by holding boost lower at lower RPM and increasing it at higher RPM to give the sensation of pulling to redline. While this may not be ideal from a performance perspective for a turbocharged application it's certainly provides a unique driving experience.
Firmware v3.4
1) Redesigned map 2 to a be a more aggressive and higher torque version of map 1, intended for those using exhaust modifications with pump gas fuels.
2) Added map 3 which is specifically designed for 91 octane and lower grade fuels.
