Title: Meth and bank imbalance?
Post by: boosted86gt on October 14, 2019, 10:58:56 PM
Anyone ever have a bank imbalance while spraying meth?

It's fine without meth and I'm running a #6 625ml nozzle with a snow stage 2 kit. Kit is brand new and the nozzle is mounted where most people mount them. Start spray is at 8psi and max at 14lbs.

Already installed brand new plugs sp542 gapped at .026.

This is on my regular tune and spraying meth per my tuner to log it.

Fields column S and T measured afr S bank 1 T bank 2.

common problem to flood the bank in the back closes to the intake. Jorden has moved it to pre IC and post IC will give you a better mix before the intake.

How many miles on your SHO?  A left field suggestion would be to check/change the O2 sensors.

There are direct meth setups available to even out the spray, but they cost.

Aren't there like 5 02 sensors on these? It's a 2015, which 02s should I replace?

Thanks

There are a Total of 4 - 02 sensors! The front primary wide-band 02's should be replaced since they control your AFR for optimum performance. Z

My single port Alky Controls with M15 nozzle, both banks on my '13 are fairly equal.  When I would check on my Aeroforce gauges, both banks were running 9 to 10 on the rich side.  Even with my new tunes where I can datalog now, both banks are still fairly equal.  Could be the 50/50 mix on the meth your using, might be the upstream 02s.  See what your tuner says.
