info about Honda UEGO sensor

[SRavet at bangate.compaq.com]

Since I posted the EFI reference list, several people have asked me about 
the Honda UEGO sensor that appears to be an NTK sensor in disguise.  I 
looked up the original post (good work on the search engine, John), here it 
is:

Or LAF sensor or whatever ....

Part # .. 395986 from 1993 Civic VX, 

Cost $130ish

Has same wires and colors as the NTK $600 sensor..

Same compensating resistance in the plug too...

The UEGO body markings are the same as the one from 
Horiba ($900+) MEXA analyzer ..

Honda wiring diags from Civic VX show same ckt. annotations
as the NTK fax I received .. 

For heater:     orange  Vh+
                yellow  Vh-

For Sensor:     red     Vs+
                black   Vs- / Ip-
                white   Ip+

Now, all we need to do is to build a DRIVER circuit
and we will have the DIY_EFI $200 UEGO sensor...

Vs. $1000 from NTK, or $2500 from Horiba ...

Maybe $250, with a PIC and a nifty display addon ;)
