Default Ign avg pulled down by cyl 5 ijeos - 05-07-2022, 06:55 PM

Can feel the car slowing down as ign avg rises.
I have tuner pro and a pretty well put together ijeos damos from transfering maps from the icmos damos and fk document.
I was thinking its related to torque since it happens even at 8 degrees of timing with over e70 just at higher boost targets. iam unsure of jb4 calc torque multiplier to get a real value, seems to max at 64 regardless of boost target:/
Lc_asr_disable is set to 1 so the dsc can go wild the dme doesn't care.
To rule out torque pulling the timing i mapped c_tq_iga_inh(disable torque reduction by ignition) set to 00(no inhibition) according to fk doc. Pretty sure its good at 0x4c81c. Still pulling cyl 5 timing at a loss here any input welcome

Have you pulled the plugs and looked at them yet? What fuel are you running as well?

You may have a bad plug in cyl 6. Pull it and see how it looks.

Its only happening on high boost and above 5000 rpm cyl 2 pulls some timing aswell. I have bin up and dowm this car mechanicly swaped injdctors new seals decouplers and coded, plugs coils, clean valves, comp and leakdown, etc... Its bin discused a ton from what i found on google but no real answer to the prob:/ i was thinking maybe the reason is cyl 2 and 5 are in the center of the exhaust manifold could the increase in back presure from high wgdc be fighting against cyl pressure? Could that be why some are finding that advancing exhaust cam is helping? Also seen some people are changing torque eff div. Although with tq inh disabled i don't think thats playing a part anymore? Ikmos doesnt seem plauged with this isue but i don't see a flex fuel bef for it. Is there a ikmos_hybrid_pi_flex bef? Its worth a shot I figure mhd makes the change easy and the power class check bit aint nothing but a 1 or 0
