Torque Management issue Magnuson 1900/meth

[andrew1988]

I fitted a 2.8 pulley to my maggie and water meth injection at the same time on my L76 A6 powered commodore.
Since then ive been having a strange, what i think is torque management, issue.
We dyno tuned the car last week and it wouldnt do it on the dyno, it only happens when snap the throttle open at a low speed.
The motor mkes boost and then it goes into fuel cut which you can see in the log.

L76 stock engine ls9 cam ls7 maf XVP820 - AC fans turned to 0% magnuson 1900 63lb siemens deka i.hpt

Has anybody seen this before?
Does it look like torque management or maybe a result of the meth turning on?
Any help appreciated.

that tune still has stock map settings, default trans limit still set, and brake torque limit still on, not sure if those are causing it tho

[andrew1988]

its maf only. ive turned brake torque off and maxed out the default trans limit.
ill give it a go and report back.

yes but map is still used durin transients and your issue is on a throttle snap, can u log MAP also that can tell u some good info also if its maxing out ect

Ok i see what you are saying. I have a gm 3 bar map i can use. Would i have to convert over to a custom os or could i rescale my vve table to read boost?

Under the VVE editor - just click on the map axis - it's gives you 1, 2 or 3 bar options... Even if you've only been tuning a 1 bar setting, it will change all 3... No need for a custom setup...

[andrew1988]

i put a 3 bar map on the car. the correct offset and changed the scale in vve editor to 2 bar. i used stock zl1 numbers for 105 kpa and above.
the problem is definetly fixed now. thank you guys.
