Default Jb4 Supra A90 setup help - 08-20-2020, 09:01 AM

I obtained a jb4 kit with ewg and ff from a friend witch was on a 140i b58 setup with wmi. I installed the unit without the wmi into my A90 Supra.
IOn map1 it keeps pulling back power and i tried map3 but then instantly goes into limp mode giving faulty drivetrain message on screen. I put 30% ethanol mix from installing the jb4.
Anny help will be greatly appreciated.
Hope i attached the log right.

Greetings from South Africa

Issue may be with the E85 mix. Let's see a log on map0 and map1 next.

Hi Terry, sorry for the delay ,i filled the car up with 95 diluting the ethanol mix to 15%
I managed one log in map 3 also without going into limp mode.
thanks for the reply .

What boost and power is the car supposed to handle on the jb4 maps with flex fuel and ******** only,if you can help me sort it?
