[DeTomaso] Techno Question: Bung placement on headers for A/F sensor

[Jerry Knotts]

Charles,

Some of this will depend on whether you will be using an electronic 
control unit or just an oxygen sensor for a dash meter.  I usually put a 
bung in the header about 4 inches down from one cylinder for an exhaust 
gas temp sender.  The oxy sensors I put in the exhaust pipe after the 
collector about a foot.  I generally put in one extra with a plug so it 
can be used for dyno tuning with a dedicated A/F meter attached to the 
dyno.  I use one on each side for the newer electronic boxes and a 
single for the older boxes (pre 94).  My 95 mustang is fuel injected and 
has a modified Ford ECM - 5 bungs: 2 for ECM, 1 EGT , 1 A/F guage , 1 
Dyno.  My 91 'P' is fuel injected has: 1 for the Electromotive GT box, 1 
for A/F and 1 extra.  My 2 carbed Ps have only one each.  I pull the A/F 
oxy sensor for the dyno.

Confusing as usual,
jerry knotts

                       I will soon have both engines out of both Panteras
   for work.  It dawned on me that this would be a good time to add a bung
   on the headers for use with and A/F meter sensor.    I have an email
   sent to Innovate for their recommendations, but it is the weekend.    I
   assume that the bung should be welded into the end of the header
   collector.


                       Does anyone have knowledge of the optimal spot to
   put the bung?
