Ive turbocharged my 1997 Jeep TJ 2.5 4cyl. 95-98 JTEC
New to tuning.
Commanded Open Loop- Temperature Increased- O2 sensors off
Full and Part Throttle PE off
Map Multiplier halved from 244 to 122
As per Map output voltage at KOEO calculates to 98kpa baro
Ive gotten the jeep to run and idle, still rich afr approx 12.5 but takes the throttle well and revs freely in neutral.
When i drive it, and log my afr is rich until I lean on the throttle past 30% or so and spikes super lean.
This spike coincides on the log with a drop in Injector pulse width.
My Base fuel Table is set slightly above the stock tune at the same new calculated pressure level.
This lean out is at 30% inj duty cycle and right at KOEO Barometric pressure.\
What am i missing?
Thanks In Advance if someone can help me out.
