Haltec V.S Pro-efi

Having DBW I think would be helpful to have in the EMS for idle stability (without having to do copy through for timing) and for not having to employ work arounds for the VDC cutting in with traction control (tied into the brake lamp signal, yaw sensor, etc) when on the track.
On the other hand, I like having the stock VDC and the TCS active while daily driving, so I don't know how much DBW really is helpful for a street car where you might want to have the safety features on most of the time. It is nice to be able to turn VDC/TCS completely off, but that requires intercepting the brake signal going to the ECU and cutting power to the yaw sensor (not a huge deal now that I've done it and it's accessible via a single switch but it was a PITA digging out the wires).

Has the issue with the CEL light triggering when the ProEFI controls the DBW been resolved.
Also does anyone know what the ProEFI can control or use out of the stock harness. ie:
Anyone have link to the software as it is not listed on their website anymore
Also does anyone know what the ProEFI can control or use out of the stock harness. ie:
- To control the thermo fans does it need to use a hardwired output or can it send a CAN signal to turn it on.
- To use launch control can it use the OEM clutch switch via the factory harness or do u need to wire in a microswitch on the pedal
- Why is the harness not supported on the 03/04 G Sedan
- and so on

If you have control of the DBW with the 128 box, you might as well let the ProEFI also control the CEL. That way if you any problems, it comes on and you know it rather than trying to trick the factory computer into thinking everything is ok.
I hardwire the fans.
The factory switch will work on the clutch pedal but it is at the top of the pedal travel and should be at the bottom!!
The 03-04 G35 sedan uses a different plug connector on the ECU that is not available in the aftermarket world. I just hardwire those cars.

Can we bump this thread after 5 years? Any new forum members have experience with the Pro-efi..especially 48. Are all the people running the same 48 out of the two versions (701) vs (705). Would love to hear additional latest review, especially from Sound Performance and Z1 Performance.

Pro EFI... Well... LOL

Thanks for the reply, but i think i may have found the answer I was looking for. My questions wasn't Haltech vs Pro EFI (although this is a haltech vs pro efi thread). I was mainly trying to see what 48 fellow forum members and tuners were running. I have my mind set on a pro efi 48. After a little more researching, I believe everyone that is running the 48 in their Z's/G's is running the 705 ecu...am i correct in assuming so?

I love mine. Flex-fuel, boost by speed, rolling anti-lag etc. It's also convenient that Pro-EFI is ~4 miles from my house.

As far as pro efi support and talking to a tuner...alpha @ induction performance will be my tuner. I emailed him the day before last with no response yet,
Which is completely understandable because I know he is very very busy at the shop and probably hasn't had the time
to get back to the email.

ThatV35guy,Yea those 2 reasons are the main reason I'm going pro efi. Can you confirm If you have the 705? If you do, I would only assume the 705 is best suited for the vq motors, especially if the guy I brought it the harness from had a 705. What firmware are you on?

ive been on the 128 box for about 4 yrs now.
the 701 has less PWM outputs compared to the 705.
the 48 box is pretty limited compared to the 128, obviously because it has 80 less pins. Most of the stuff I run doesnt really need to be hooked up in a basic build.
Alpha should be traveling to NC this summer, dunno if hes going to TN. Remember, he locks his tunes, so you cant make any changes or even look at the file....
but here are a few differences between the 48 and 128...
only 3 injector outputs, so you have to run batch injection not sequential. Only 1 cam input and VVT output, so your 2 cams and VVT are bridged.
no onboard wideband controller
no digital input for ethanol sensor, so have to buy convertor box
not enough input for extra sensors like oil temp, radiator pressure, nitrous, etc.
