I know ProEFI supports DBW, whether it works right on these cars/TB's, I'm not really sure

Atomic C6

Interesting the two times I tried it without them I get Low tire presser warnings and no sensors detected and it will not go over 50 MPH. I guess I am just unlucky with mine.

Unreal

No idea if there are year to year differences or what, but I've never had as issues besides DIC saying "XXX" on pressure when I don't have the sensors in. Even then that is after 100+ miles, and if you park next to your tires with sensors, it resets. I drove for months without even a code because I wouldn't go over 100 miles in a day, and just park next to the street wheels in the garage at night.

Wow! Some great info here guys! Thank you so much for your input. I had no idea exactly how this stuff works.
All I know is that I wanted a mix of engine management and protection as well as boost-by-MPH.
Is the traction control that a stand alone like Pro EFI provides, separate from the boost-by-MPH, or is it one-in-the-same??

Unreal

Separate. Proefi will manage spark/fuel/etc to limit wheel spin based off the wheel speed sensors.

I have seen Joe G post a pic with the TPMS in a sealed PVC canister. He keeps it in the car. This is just food for thought.

This is going to sound mean, but if you aren't going to learn about the benefits of ProEFI, why run it? If you are using it for just boost by gear, you could've bought a Eboost2 for much cheaper.

ProEFI's traction control is arguably the BEST feature it has--why would you ever want to turn it off? I would suggest becoming familiar with it and understand how it works. Otherwise, you are leaving so much on the table.

The (I'm assuming) dyno tune you received will be good for every day driving, but another great benefit of ProEFI is being able to data-log and adjust on the fly for event's like 1/2 mile racing. You can noticeably tell the difference in slight adjustments to the tune based on the data thats being collected from you prior runs.

You can set the throttle body up either way. I had it controlled by stock ecu originally and it kept getting sucked closed or just not working like it should. We swapped it over to ProEFI control and set how far it opens and all that and I no longer have issues with it closing or acting up like it did on stock ecu. They just put another stock tb in the car to keep the stock ecu from getting all upset. While ProEFI controls the NW 102mm.

schpenxel

So you've got another TB hooked up that's just opening and closing and not connected to anything else?

SquirrelyNutz

Yup, so I don't have a reduced engine power code coming up all the time.

In the 1/2mi I went 155mph in Comp Mode and 170mph with TC Off. No other changes were made.

My tuner here in Deer Park, NY is telling me he has to have my stock ECU control my throttle body cuz there's no way for my ProEFI to control it. Is this true or nonsense?
I want Pro EFO to control as much of my car as possible. I certainly paid enough money for it!

SquirrelyNutz

Your ProEFI can control your throttle body. Mine is setup that way. Although stock ECU controlling it will work just fine as well.

schpenxel

Once upon a time pro efi couldn't control DBW throttle bodies, but it's been an option for a year or two now (at least)

NYOverlord

I was all set to buy a NW 102 throttle body because I want to make a little more power, but Lethal Performance in San Antonio, TX has done several TTIX Kits on Corvettes and told me I'll actually lose power and the NW throttle bodies "stick".
Are either of these points true?
If you picked up power from the NW 102, how much so?

SquirrelyNutz

ZR1s pick up a lot from a TB swap but a car pushing boost through the TB won't gain near as much. I think you are better off sticking with a stock TB so you have no issues. If it worked properly you would probably gain some power, but in my opinion it is not worth the headache or possibility that it won't work in your case.

schpenxel

Stay stock TB. I've heard NW is testing some new stuff that'll do better under high airflow but for now don't bother. Small restrictions post blower make a much smaller difference than restrictions pre blower. Thus the reason for gains on zr1 type setups.

Unreal

Plus stock TB will support more power than that turbo kit will ever make.

SinisterC6

Yup stock TB is the way to go.

With pro EFI doing traction control turn the OEM system off (holding button 10 seconds) so it doesnt get confused

For your wheels can you purchase TPMS and a GM reset tool? I did that for my drag wheels and reset the sensors when I swap wheel/ tire and prevents any additional warnings

This info is gold!!!
