hi..
i have buy a plx devices egt...they have a analog output 0-5 v...can i wire this analog output to the ELD voltage for see in my datalog the Egt voltage??

It is not somethign we have tried, but the settings in Kmanager will allow you to enter whatever values you want into the wideband input conversion table, so it is theoretically possible. Although it will display this as AF not EGT.

this sounds good :D

I have been running a EGT probe connected to ELD for about one year. No problem so far..

where is the pin ELD in a PRA ecu???

ELD pin = pin 15 in the E connector
Have a look to the Help Manual - Contents - Reference - ECU connectors

ok i see it, GRN/RED wire...i cut it and next weld my egt output wire?

ok i have cut the stock E15 eld voltage wire and connect my egt output!
but is strange..with engine cold i have an ELD voltage of 1.20 volts when my egt output is about 0.3 v...why??
I have measured the eld voltage pin without the egt wire and i have 4.96 volts and in the datalog the same...
i connect the egt wire and measure i have 1.20volts and the same in the datalog with engine cold..in my egt graph with engine cold i have 0.2 volts of output..
why this??
i do use a offset in the setting of kmanager??

i can try with a resistor 1Kohm between the ELD voltage pin E15 to the ground???

To match the EGT that you see in the PLX gauge with the EGT that is displayed in the KManager, you could put a voltage offset or alter the values in the wideband input conversion table (KManager - options - settings).

i have try this but is very hard...i use the plx table for the output egt and put the value in the kmanager wideband table!i warm up the engine and next at the idle for 10 minutes..i see the exhaust temperature on the plx display are about 410 °C...and i change the offset for see 410 in the Afratio display or kmanager!i see the offset is about -0.35 v...possible?

with afr 12.0 in WOt 5 gear i see max 697 °C...i think..too low?
