hey
i bought a modified p07ecu with s300 v1.4.1.0
display shows eld = 5 v so i wire the lc1 to D10
is that means that the ecu is already modified ( cut R12 and R18 resistors in the ecu )
i cant open the cover of the ecu ( sorry )
thank u in advace

Note that if the ELD input (D10) is used then R136 and R138 (US ECUs) may need to be removed.

ya i know if i need to use D10 R136 and R138 shloud Be removed but before i install the lc1 my display was ELD = 5 v what i want to know if that means that this 2 R are already removed from the ECU .
second how can i measure the voltage offset and in the closed loop parameter THREE ROWS i need to know the exact numbers in voltage and AFR
note: version 1.4.1.0
thank u in advance

You have the ECU in front of you, open it and see if the resistors have been removed.

This Image Depicts My ECU , gonna appreciate ur help to locate the R136 & R138 by red circles , then plz re apploud it back .

R136 , R138 Location

thank u :)
i'll remove it, and find the voltage offset ( lc1 connectd to d10 ) do u have an idea how can i measue the voltage offset ,
i read many art , but complicated
anyway thx

Compare both s300 and logworks AFR readings, if not the same adjust voltage offset to get it correct.

The yellow narrowband wire is to be connected to D14

The brown wideband wire is to be connected to D10

It's best to connect the ground of the LC1 to the thermostat housing, that where the ECU should be ground.

hey
i connected the yellow wire ( analog 1 ) to the gauge not to d14 narrow band signal, i did it as the innovate manual . is that fine ?

If the gauge is a wideband gauge 0-5volts then it should be connected to the brown wire

Yellow wire is for Narrowband operation 0-1volts (D14 O2)

Brown wire is for Wideband operation 0-5volts eg. datalogging with ECU and DB gauge

thank u , i rly appreciate ur help :)
i'll fix it tom

hello hondata team :)
plz may u help me , i need to use this ecu ( pic above ) to boost my car . is it ok or some Components must be added to the ECU for the PWM output to work?????? with turbo. if use wat is the components and where to get it ?
thx in advance
