If you're experiencing more aggressive Map4, then it is likely the JB1 maps are now the same as the JB4 ones (keep in mind you can't run boost quite as high with JB1, so follow JB1 guidelines). Originally I think JB1 was only suppose to have Map0,1,2,3,6 as listed above with 2 being the 93 octane aggressive tune.
Here's the Maps list for JB4:
"Maps are based on 60/85//5 and newer firmware.
Map 0: This is a stock map with JB4 logging ability. It is also the starter map for cars that are running flash tunes and are stacking the JB4.
Map 1: Tuned map with a average of 4.0psi over stock. This is the shipped map and is compatible for both 91 and 93 and can be used with cars on hardware.
Map 2: Tuned map with 5.0psi peak boost over stock. 93AKI/98Ron recommended
Map 3 Peak boost 6psi 93AKI/98Ron recommended
Map 4 Peak boost 6psi (Golf R and Audi S3 7speed DSG specific), it has a taper at higher rpm so will also work well for all on 93 in hot climates
Map 5 Absolute map peaking 25 tapers to 20psi. E30 with bolt ons needed. (not to be used on 1.8T or 2.0T Jetta)
Map 6: User adjustable boost map. The map comes preset with a 5.0psi over stock peak and is ready to use on any car running 93 octane. The preset map is also suitable for manual cars with clutch longevity in mind.
The mapping can be done in two manners. If the value at 1500 is kept below 10 it will work as a boost adder map. If the value at 1500 is higher than 10 it will work as a absolute map. This means actual total boost targets will need to be entered.
Map 7: Meth integration map using our FSB Meth controller
Map 8: This is a valet map/safety map where 50% of the boost is cut. It will give the ability to log the car via the JB4. This is also the safety map, so in any circumstance the JB4 detects a unsafe condition regardless of map it will default to this map. This includes knock detection, lean AFR or the boost safety value being triggered due to lack of boost control.
