Scott, if your reply was directed to me about charging $1200 to upgrade, you have misread my posts. That was my point, if someone quoted the OP $1200 over the price of the HP system, he was getting ripped.

FYI, this is not a sales pitch for whomever complained earlier today. Simply trying to give the OP a heads up before he got taken advantage of.

As far as the O2 sensor's go, very seldom will I use a Bosch sensor unless it's on a pump gas, N/A carb to efi conversion, IE stock style applications. You are correct the NTK is a much better part

if a 275 Radial and 900 HP dont mix, then you need some serious suspension work....
if you look at the x275 class.... those guys are doing 4.x in the 1/8th at over 200 mph on a 275 Radial at over 2500 hp on some of the cars...
Wow.. had no idea that was even possible.. Thanks for the info.

ok so mike@SKspeed was able to match and hook me up with a badass price. Anyone looking into this unit should drop him a line. With that said, He does not have a good source for the NTK O2 sensors. Does anyone know where I can get those on the cheap?

You don't buy the sensors on the cheap

You buy them straight from Holly because they have taken the time to put individual resistors into them to calibrate them properly for the holley ECU

I've been looking on flea bay and they vary from $230-$193 all of which have the holley part number 554-100. What I meant to say is who has the best price on these sensors. If it has a holley part number on it does that mean that it actually came from holley?

They don't come FROM Holley. Holley buys them, and re-sells them in their kits.
If it had the same part number as the sensors in the Holley system, they are the same sensor Holley sells.

Holley Buys them, modifies them, then repackages them and sell them as 554-100

if it didnt come in a Holley packaging, its not the same...
I had asked Doug this very question because I had found the sensor quite a bit cheaper and wanted to know why theirs was so much more.
he explained to me that they actually test and calibrate each one to a specific value to guarantee accuracy

so while you may find the same sensor...if its not in the Holley Packaging with the number 554-100, its not the same thing.
Not all wideband controllers react the same and every manufacturer uses the sensor and modifies it in some way to make it accurate with their controller, whether its in their controller or at the sensor, they all do it to some extent


and when I said you buy it from them... I didnt mean you buy it directly from them...obviously its a part # that many vendors can sell...all I meant is that it needs to be the Holley Calibrated sensor to guarantee accuracy with their ECU.

Any idea where to get them for a good deal? oh and one thing i forgot to ask you. Does the main harness plug into the knock sensors? I assumed the holley main harness would just plug into my single wire valley cover knock sensors but i seem to remember reading something about needing an additional harness

as far as the knock sensors go...
my LS1 knock sensor harness connects directly to my Holley LS1 harness....
nothing special needed..

Be interesting to know how they calibrate an O2 sensor. :-)

they add a calibration resistor in the shell I was told.

each sensor is tested, and then a resistor is added to make it reflect a certain value.

Tough environment for a resistor. I think somebody is feeding you a line.

its not that tough of an environment...the shell is pretty well protected
and I've repaired devices that use special High temp resistors...

Lights in the concert industry put out as much and more heat than exhaust sometimes...have to use a special silver solder and a really high temp soldering iron for it(1200*~1400*)....pain in the *** ....


I wish I knew more details about what exactly they do to them....


its also listed on several sites that holley puts in a calibration resistor

heres one of the places I found it mentioned

Scott is telling you the truth. Call, and ask Doug Flynn should you choose not to believe us.

Just read the whole thread, there's some good info in here.

I've been pricing a dominator setup all week

554-114 ECU
558-103 LS2 harness
558-201 LS injector harness
558-308 main harness
558-401 O2 harness
558-405 4L80 harness
554-100 NTKs -2 of them

The best price I got so far has been $2700, not bad considering Holley quoted me $3050.

Would anyone know of a good company to call for another estimate ???

Does the dominator come with launch control built in? i was reading about the LNC-003 and other units that kill revs when the clutch is activated to make things easier on the trans for no lift shifting etc.
