Hondata

Hi.
Engine - 2004 k24a2 with accord cable TB so IM is same[*]
kal: 04-05 tsx basemap
chassis: 2000 mr2 spyder
wideband: plx
Car is running crazy rich. the only way to get to idle is -40% to -50% across the board.
tps is calibrated, iacv is cleaned and working. MAP appears low, but I swapped for a known good one and got exact same readings.
New plugs.
I'm not sure what else to check. I thought this would be an easy swap using a stock engine and stock kal

Reduce the fuel until you have it where you want. It is possible your car does not need all of the fuel that is on the base calibration. The fuel trim is maxed at -34 so the car has reduced the fuel as much as it can.
