We have lost multiple high end 02 sensors as well on non leaded fuels.
Also have seen the very expensive dash everybody raves about go out and never come back on.
Nobody knows why.
Coil packs have failed as well.

The main differences between the systems inmo is the traction control system.
the processor speed is fast enough on all of them and only taken advantage of when using the faster more expensive wideband!
the holley has an advantage over the in the traction control and other tuning areas.
And fuelteck is a step about all inmo.
That more racecar inmo for the dedicated.
And you will be paying for that
Holley has allowed many who aren't that great at tuning to be user-friendly enough to get things moving in a better direction easier.
Like all systems though the better tuner you are the better the car will run.

Actually there are more out there than you think.
Street guys keep things quiet for a reason
and top notch components are not always needed to run these street times depending on the "approach"
Which is overlooked and not known by many.
The boost and traction control is impressive
Yup
He could have safety with an electronic boost controller with co2 which is a stand alone setup for not that much money that would piggyback on any computer system
Why would anybody want to not use the faster wideband correction sensor?
Defeats the hole purpose for having the extra inputs to see what all the sensors on everything in the car doing?
If someone can't spend the $400 on the sensor they won't need that level of computer system.
It's well worth it and makes everything including drivability better.
all the info is from the o2
Spending the $ to see shock sensors etc and all the other things that go on with the car can be on a much faster sensor and is the main advantage in upgrading.
And we'll worth it.
We have spares if one goes bad.

I've had that, Holley weak battery lose the tune issue, it was horrible timing since it was a fresh engine.
Tuner nearby is most ideal but there's so many remote Holley tuners that Holley is starting to be an easier choice since Cruz makes a plug and play kit for us. The 12" Dash is really nice unless you like the cockpit guages like me.

I believe the current tune in the ECU is automatically saved to the dash every time the dash retrieves it from the ECU. It's saved in the INTERNAL memory and named config.hefi. I've loaded that file from the dash once because I disconnected the battery with KOEO and the ECU lost the tune.

The Holley forum members are seeing an increase in this issue.
Seems there's a problem within the ECU from the gitgo....
A link to some of the chatter.
The bosch sensor will not take the abuse a ntk can period. However the NTK is not bulletproof that is true. Its up to the end user how he wants to go but on the ECU-GN its not an option .

So ECU-GN is 200 Frame Rate, XFI is 100, I believe my Fast Bank to Bank is 25. What does the stock ECU in 86-87 reading at I wonder?

I have been running both systems for a few years now and they both have their pros and cons
On my GN, which is a drag-drive car, the dominator is the best choice IMO. With all the crazy stuff I do with that car, the flexibility it has and the ease of use of the software with endless input/outputs that are easily configurable and the advanced tables make it the best choice. Especially for a DnD car.
My Ttype has the ECUGN which is easy to install has plenty of options and IMO does flex fuel much better than the Holley. That ECU is really nice for the Buick guy who wants to plug one into a mostly stock TB and have WBO2 control with flex fuel which is totally PnP. IMO It is also worth the extra $$$ over the MS3 PnP with the added feature Eric and Bob built into the system.
Boost control is a BIG win for the Holley, I don't use the Holley traction control and have a Davis box on the GN that I haven't used much......yet!!
MS3 software IMO sucks, but the wiki and online info is pretty extensive making it easy to get help plus Eric and Bob are awesome and always respond to questions and are real assets to the Buick community. I have my Ttype apart right now for some updates and I am getting ready to dive deep into the ECUGN setup again. I will be adding CO2 boost control with dome pressure and a bunch of additional inputs/outputs. I am also building a custom harness for it mostly because I hate the factory harness that much. I am actually separating the chassis harness and ECU harness completely and making them two independant harnesses if that makes sense. It will also allow me to swap ECUs easily if I ever decide to put a Holley or even Fuel Tech in it and I am making the ignition pinouts so I can run different systems if I decide. Right now I am swapping to truck coils with wastespark. I will also drop from 11 different relays under the hood to just 4 or 5.
I have not had any issues with the WBO2 on my Dominator. I also have a spare just in case which if you have a DnD car you need a spare of everything anyway. NTK sensors have never been cheap but if you run any type of leaded fuel you will need one IMO. All systems seem to use the same NGK PN 24300 L1H1 NTK sensor. The different manufactures change the plug and add a "calibration resistor" to make you buy thier sensor. FAST, Accel and now Holley all do this. IMO if you are not going to run a leaded fuel I dont think there are any real downsides to running a Bosch over the NTK.
Glenn at MAD Racing sells the NTK sensors with calibration resistors for the different systems for not much more than they cost new. The NTK sensors even when buying from a parts store have always been expensive even since the early 2000's when we first started running them. When Holley has a sale you can get them for $280 which really isn't that bad.
Cons for Holley, customer service is HORRIBLE and Holley is NOT cheap either. The cost vs service you get IMO would make me use a Fuel Tech or Haltech if starting over again knowing what I know now. I would avoid a Term X all together I have seen issues with them. We also had a brand new HP lock up on the dyno, sent it to Holley they admitted it was an internal issue and ECU was junk. Since it was purchased over 90 days ago they told us to have a nice day and sent our paper wieght back. Assholes is about the best I can say about them and I have even more BS stories in trying to deal with them they really suck.
I have played around with both the the Haltech and Fuel Tech systems and they are nice with plenty of cool features and options but I do still feel the Dominator is a better system overall. You can't beat the software, the configurable I/O's and the endless capabilities the advanced tables that can be designed to do just about anything you can think of with the use of the configurable I/O's which really makes that system far beyond the others.
I am probably going to use a Fuel Tech on my next build which is my 67GS twin turbo pro-touring car I am hoping to tackle this winter. It has a few features I like for that build. Like the built in gyroscope and accelerometer and display screen. Plus I like how it is modular and the price is a little better than Holley too and dont get me started on Holley custmer service lol. IMO Fuel Tech is a really good system for a car that is more track based adn the end user that wants something simple and easy to install and use with good support. The Dominator does a lot but it is also easy to get lost in all that it is actually capable of. Most people I see with a Dominator really dont even need one and usually are not using it for what it is fully capable of doing. If I were doing a build and considering an Holley HP or Term X I would definitely look at Fuel Tech first. If I was doing a LS swap I dont think there is anything better or cheaper than the Haltech Rebel.
In closing I dont think the new systems are really that much better than the old systems like Accel DFI or FAST XFI in terms of making more power or being any better at running the engine. They all do the same thing when tuned correctly by managing air spark and fuel.
FYI I still have not gone as fast in the quarter with my GN today with all its modern widgets and do dads as I did in 2009 with the Gen 7 and a distributor!!! lol!!

Interesting statement
Its how the widgets are used

I agree and I have gone faster in the 1/8 and I have made more power on the dyno, but that is mostly because I have more useful data to go by.Its how the widgets are used
Another interesting statement: A carb is still King and will make more power than EFI.!!
Right the info/data is how we proceed to get the car from a to b sooner.
But in the end its how the data is used and how much testing the car and driver has had.
The ability to adapt to multiple surfaces and temps with the new systems have never been done before.
And I will add most guys would have never gotten to where they are without it
Or where they want to go with a chance to get there.
Up Scramble de scramble buttons,traction control,g meters,etc.
Are all things that in the right hands will make a faster car with a specific driver.
Carbs can make power for sure
But in the land of real racing where your moving locations on the street or different tracks with conditions that vary the ability to adapt and manage your power is the real art not just overall horsepower inmo.
