Hey all, here is a log from an on3 single set up. Mods are...

-On3 kit w/on3 tubo
-44mvr with 11.6psi spring
-gplus intercooler w/oem ends
-vrsf cp/hks
-stock fuel
-stock tmap

This is a log in map2. I am new to the jb4 but set all the dutybias to 50, the FF to 20, & WDP to 75...I am hitting just under 14lbs on map 2. I thought map 2 was 17psi, do I have to change the FF to get more boost or do I have a boost leak? Map 1 hit WG spring pressure @11.6 just fine very consistantly.

Lmk what I can do to better to dial it in. Any help is appreciated. I am new to jb4 set up. I usually use mhd only for single n54s.

Probably a good thing that car didn’t make anymore boost.

Need more details...

Which ST flash of ours are you using?

Fuel?

Fuel bias settings- set to 0, yours are all over

Dirty bias- set to 0

I loaded jb4 firmware: N54_G5_MAC_136_T4.hex with a mhd backend flash.

The car is on stock fuel running 93.

I will be back by the car in about 6 hours to continue troubleshooting

Here are the map 1 settings. I will be posting a log soon once the oil temps are up to par.

Here is the map 1 log

Fuel bias all set 0

I set duty bias all to 50 per the set up instructions.

Please let me know if you think I am safe to try map2.

Thank you very much for your help

after some research I found I have some setting wrong for this log. I have changed them to what they should be. Here are the notable changes and then the settings as they were set for this log.

N20 TMAP was @ 15 I changed to 0
6-cyl timming was @ 15 I changed to 4 for I8AOS

Map1
Fuel bias all.......0
Dutybias all.......50

Boost Safety.......18.0
Default Wastegat position...........75
PID Gain..................................25
Auto Shift Box Redux.................60
FF/Wastegate adaptation...........20
Fuel open loop..........................47
Meth safety mode(1-3)..............0
Meth Trigger Mode(1-3).............100
Max Boost 1st..........................0
Max Boost 2nd.........................0
Max Boost 3rd..........................2.0

Future A..................................0
options(tap button to view)............Never open this
N20 TMAp (0/1).......................0
6-cyl timming logging(0-6)........4

Here is a new log in Map 1 wit the setting as listed above.... not sure if things changed. If this looks good then I will load map2 with the same settings....

I also notice that when I switch out of Map1 to Map0 or Map2 then back to Map1 all the Dutybias values return to *0* for Map1. In Map2 they hold the dutybias value to 50 regardless of leaving the map and returning.

That’s normal.

Jump up to map 2

Here is a map2 log it felt good in 2nd, but seemed to break up in 3rd. I had a lambada code...

2c6e lambada probe behind cc 2, aging

I am assuming the o2 sensors need replacing. There are no o2 sensor codes in map1, only map2.....

Thank you so much for the help!
