The ultimate LT1 $$EE patch thread

[E-Ticket]

Thanks for the updates. Purchased FAST dual wideband kit, plan to wire into D12 (with a switch) and D27 to log both sides. May also add switch to ground B23 to force open loop in case things still get weird at the dragstrip.

First going to just log my idle/cruise O2's to make sure everything is happy and get it all adjusted for regular driving/idling before going to tune WOT on a dyno.

For a dual wideband setup you`d better use pins D12 and D21 or pins D27 and D31. The pullups resistors on this pairs match and there will be no ground potential difference between the two channels, thus more stable readings accross banks.
D12 and D21 have 50 kohm resistor.
D27 and D31 have 22.3 kohm resistor.

If you have troubles modifying the datastream it is a simple 2 bytes patch. Give me a note and will get an xdf for an easy reconfigure.

Thanks! Yes let’s do 27 and 31 so I don’t have to deal with AC. I need to install all the tunerpro patches to get everything sync’d up first.

Apply the patch labelled "Log pin D31 on AC pressure channel [Wideband patch]" and at the AC pressure you will log pin d31 instead of pin d12.

Pin d27 is already setup in the datastream so leave it like that.
Select pin d27 as wideband input in eehack settings. To get an accurate value for wideband channel 2 change the eehack definition file. Find the ac pressure and change the conversion so it matches the setting of the wideband input.
