Anyone have experience with this ECU?

I need a nitrous progressive controller and a data logger for my car, this ECU does that and a whole lot more.

I'm going to stay with a carb and wet nitrous for now, but I can see going MPI and dry nitrous in the future. Traction control is a huge plus too.

My questions are:

Do I need to use a TPS to activate the nitrous? Or can I still use a WOT switch and have the nitrous come on with the release of the transbrake button?

Can I use the ECU ignition control with my current MSD distributor and coil? Or do I have to go with a cam sync and CNP?

If you are going full EFI then you will already have a TPS to control fueling so using it for nitrous control will be very easy. Would probably harder to figure out how to use a WOT switch. You can have multiple requirements that need to be active before the nitrous will enable. For example you can have nitrous system armed, TPS greater than 85% and transbrake not active. This will activate the nitrous system on the release of the transbrake.

You can use your distributor, coil and I assume MSD box to control timing and retards. If you move to a cam sync and CNP you avoid any possible issues with distributor phasing and can plot a timing curve. This is helpful when you are maximizing your timing with the system on.

I plan on staying with a carb and wet nitrous for the immediate future. I will switch to MPI and dry nitrous at some point in the future.

After looking into it a little further, I'm going to go with CNP and a cam sync right now.

I know people that know Holley EFI stuff like the back of their hand, but I race against them and multiple cars that they tune.

There is a Holley EFI group on Facebook with a lot of good info. I've been using the search feature and getting a clearer picture of what I need to do.

Consider a crank mounted trigger wheel and a cam sync for greater accuracy.

I thought the progressive controllers used a time based ramp?

I'm going to use my existing MSD crank trigger with a Holley hall effect sensor.
I'm going to call Luhn Performance tomorrow to order a cam sync.
I'm going to use oem D585 coils.

Using the Holley ECU and going CNP seemed complicated at first, but after a few hours of searching the net, it seems a little more straightforward now.

The Leash progressive controller I have in my other car is a time based ramp.

I assume the Holley is as well. Everything I've read about the Holley controller has been positive.

[Scott65]

I don't use Holley, but I found it pretty straightforward. The timing is rock steady with the 36-1 crank wheel. You'll like the versatility.

[Scott65]

Lots of control options with an ecu. Safeties too.
Not Holley, just an example.

I run CNP with a carb using the Haltech VMS. I use the MSD hall effect crank sensor and the cam sync from LPI. I run a 16volt system and found the stock coils didn't meet the need and moved to the Holley smart coils. I know they are not cheap but definitely much better in my experience on a 16volt system.

I control nitrous and fuel progressive on two separate curves, cylinder to cylinder timing, trans dump valve and log 20 channels. Overall very happy with the system.

I also have a Holley Dominator that I plan to upgrade to and have built the program for that on the bench.

[Scott65]

Nice! Any plans to also control the fuel/dry nitrous?

Thanks for the pic!

Yes, that is the plan. If you look at the intake you can see where I have the injector bosses covered. We keep getting distracted continuing to optimize the combination.

So far it has gone 4.93 at 143 in the 1/8th with a 1.16 sixty foot time. Car is a little over 3250 with me in it and I am at 1877 lbs/hr on the system. We want to get another 200 lbs/hr through it and the timing curved worked out and we will probably switch over to EFI.

That's a sweet set up! I plan on mounting my coils just like that, thanks for the pic!

Do you see the car picking up ET/MPH with a switch to EFI and dry nitrous?

[JD]

Not necessarily but it will allow finer tuning over the fuel side hole to hole which should help optimize the overall tune up. I am also expecting I will run into a point where the engine is getting close full saturation with the nitrous and tuning each hole with EFI should be a little better than changing fuel changes in the nozzle.

I also like the option to run with the throttle body exposed to open through an opening in the hood when I cannot run a forward spacing scoop. May not be too big of a deal but looks cool in my opinion.

Very NICE, JD!

On my friends carbureted car we use FuelTech for the progressive controller, Timing retards and traction control just as you can with the Holley. A TPS is a must though as it will need to see the TPS to activate and perform other functions. The green in the pic is how he mounted his.
