Hondata

ok ill keep it in open loop. thanks for the advice. ill retune it too.

i think i found the problem. i was running closed loop . so put it to open loop and its running fine now. would i need a retune? and then just keep it on open loop ? i have aem wideband hooked up to the s300 and i still have one of my stock 02 sensors.

my car is a 98 honda prelude base
setups are
gt35r turbo,
1000cc rc injectors
synapse 40mm wg
hondata s300
boosting 18 psi
running e85
gm 3 bar map

my question is . could a bad or defected ecu make you run hella rich?.. my wideband is reading 10 on idle. and the car smells like a gas station ...
