Got my JB4 this morning. Can't wait to install it! I'll just make sure it's up to date in the meantime though.

Welcome to Planet Power. The 335iCoupe which I loaded with JB products (12.1sec without Meth) ran at ODR today with meth. Made 450wheel Hp.:=): They said that it's the strongest x35i they had, had on their rollers to date.

Which ISO version would you guys recommend? ISO_21 is no longer on N54Tech, just 19 and 22.

 

[Richard H]

Go for iso 22

Id say, if you dont have any rattles, go for iso 19. 22, has more user adjustment in it for the guys suffering with rattles!

 

[tmos]

22 is sweet with nice optional tweaks! :thumbs:
My car is loving it....

A big Thank you to Rennzport and their professional installer in Durban for putting the JB4 on my 135 last night. Excellent service, very knowledgeable and helpful... Wow, great fun and very noticeable power/Tq gains

some good news on the horizon,

the new Map 7 coupled with the BMS flash and walbro upgrade, is good for 430whp, i am saying 430whp due to our fuel quality. However the true potential is around 450whp.

I have tested 100% eth the other day and i only manged to get 434whp.

i strongly suggest the latest firmware upgrade, and for those wishing to push there turbos to the max ISO22 is great for adjusting the duty cycle.

 

[bmsportzn135i]

Theres already a 23B and Terry has got some guys testing out a 23C!

Well done bybyM3, we need a 11sec 1M. :thumbs:

I have a question how would you reset all maps to there default settings if they were changed ? I am getting a second hand unit but nervous about the map settings

Eish man. I seriously suggest you get some one experianced to install and update your firmware for you. You shouldn't be attempting this as your own diy if you asking questions like this.
We all here to learn but I strongly suggest you do some more research.

To answer your question, only map 6 settings can be changed. Other than that u canot change the parameters of the other maps.
When loading the jb assuming u have ISO than click the box that says rest to default settings.

Good luck man. Enjoy.
