I have the Holley Commander 950 Pro and I want to replace it with something more modern.

Engine is 350 SBC with just over 400hp.

I want a throttle body EFI that is fully self learning system that will also manage the ignition with MSD crank trigger and MSD6AL.

Looking forward to your valuable advice.

Thanks

I have the Holley throttle body EFI and am happy with it.

If you want electronic timing control, just upgrade to the current Holley system - I think it's called a "Terminator". You may be able to keep your throttle body/injectors. Suggest you call Holley tech support or post this question on Holley EFI forum.

I think there's a version of the FAST EZ system that could do what you want also. Probably harder to keep your current throttle body.

I'd look at another computer system that could be used instead of the integrated throttle bodies. That way, you just change the wiring and install the new computer and you're running again.

Still, it's hard to ignore that you can get a Sniper system from Holley for <$1000 and just replace the TBI too.

What model Holley TBI do you have?

I purchased the Terminator system and did not want to have to go through the effort of cutting all the wires and crimping on new terminals to make the wiring harness fit my car perfectly.

I've been reading that newer TBI's have the computer built into the throttle body and only a few wires, 5 or 6, are needed.

Which model FAST EZ would you suggest?

I don't understand following comment " I'd look at another computer system that could be used instead of the integrated throttle bodies. That way, you just change the wiring and install the new computer and you're running again."


I will look at the Holley Sniper, Thanks!

I have this kit https://www.holley.com/products/fuel_systems /fuel_... On my 327 in my '57, and on my 350 in my other car I have an older HP throttle body kit,(not port injected). I don't think they make that kit any more, it has been replaced by the Terminator. I believe in getting a system that will control engine timing and have options for more inputs/outputs. For example I have it set up for the ECU to control my engine cooling fans. It also can be set up to control torque converter lockup. Larry

Integrated TBI has almost everything in the TBI.

The Terminator system can run circles around a Sniper if you use any of the extra capabilities. But if you don't then the Sniper is a good choice.

I wouldn't use any of the FAST EZ systems after reading how many people have had "noise" issues with them over the years, causing their engine to not run right.

Those $1000 systems like Sniper and FItech don't have fully electronic timing control like the Terminator system does, and the OP wants. They are also still in the "teething" process as far as reliability and easy installation.

I know a couple of satisfied FAST EZ users. But they don't have the full timing control either, though the "EZ 2" has a limited timing control.

I'm not sure where you get your information from because the Sniper certainly can control timing and it will work with a MSD ignition box. The info says it can use a hall effect sensor so I believe the Holley 554-118 would be used assuming the OP has a flying magnet crank trigger. The manual really only covers distributors but does say that other hall effect sensors can work.

The Sniper even has launch timing retard & launch rev limiting It can also run fans and nitrous. So, it's got some interesting features that a more advanced user might need built-in.

Boost is listed in the manuals but a note says the 4-barrel TBI kits don't support it. I suspect it's a future feature so maybe there eventually will be Sniper port injection kits or more advanced TBI kits.

It's my understanding that the Sniper and other price leader systems that do have timing control only allow you to program a timing curve with a start point and end point vs. rpm and vs. MAP. The old 950 and the newer HP and related controllers allow full timing control by entering values in tables. The timing would not have to follow a "curve" over the whole range. In other words, you can have a non-linear timing curve. Example, you could have constant timing vs. rpm from idle to 2000 rpm, and have it increase on a "curve" after that.

I've not used any of these systems so they may vary in their features.

You should at least learn about the system before making claims about it....

If you use the software, the Sniper timing controls give a pretty big 2D timing table, 2 ignition rev limiters, launch control timing retard, a timing add/subtract vs coolant temp table and a timing add/subtract vs air temp table. So, you're quite wrong about it just allowing a simple timing curve.

I finally made the purchase of a new Throttle Body EFI to replace the Holley Commander 950 Pro Wideband. I purchased the Fitech 30002 Now I need time to remove the Holley and install the new system.


I'll be selling my complete Holley EFI system which also includes the LED gauge that shows the fuel/air ratio. I've put 7500 miles on the system. Anyone have any idea what the EFI is worth? I'll also be throwing in the laptop that I use to tune the system. Appreciate the advise and comments

Too bad you went FiTech, I have many bailing off them, and FAST in favor of the new Holley systems.
