Tons of Check engine codes
Finishing up blower install, pinned the ecu. Ended up with a boat load of low voltage codes.
P0178 fuel composition sensor circuit low voltage
P0807 clutch position sensor circuit low
p0122 tps circuit low voltage
p0223 tps to ecu voltage too high
p0315 crank position sensor variation not learned
p2122 tps circuit low input
mh tuner suggested a switch to a 2010+ ecu, which I was sent with a base tune on it. That is the ecu I’m running. Not sure what to do as I can’t possibly have that many issues on a car that ran fine previously. Any help would be appreciated.

Found out the clutch position circuit and crank position are due to tune, so I can take those off the table. I’m gonna check the pin for the ecu and flex fuel sensor again, to try to clear that one, but the one that gets me is the tps circuits. There is no reason it should have those.
