I had a blower (now going to twin turbo and a Pro EFI stand alone ECU) and have 3 bar MAP sensor and don't plan on running over 25 PSI. I have a PLX Devices Generation 4 Bosch LSU 4.9 o2 sensors as well as the PLX Devices Air/Fuel Ratio module. Can I re-use the 02 sensors, or must I actually downgrade my o2 sensors (and sensor harness) to Bosch LSU 4.2 as one person told me?

 

What model ProEFI is it? I thought they could use 4.9 sensors

 

subscribed,,, in the market for a stand alone ....was looking into this unit also

 

Here's what I found out. Only the newer Pro EFI 112 model can use 4.9 and they can't just be any 4.9. It has to be specific versions of them.

The older 128 model must use only 4.2.

The 112 is only out for the ZR-1. All other vettes must use the 128 model. They aren't planning to release the 112 for any other model in the near future. Looking at more than a year for it to come out for the other vettes.

The difference in models is that the new one is faster reading, easier to install, and $700 cheaper cuz of the more efficient design.

I am going to order the 128 model because I'm not waiting over a year for it to MAYBE Coke out for my car.

I need every nannie I can get to keep my car straight so I stay alive and win more races by staying in a straight line and crossing the finish line first. The unit itself is $2,700ish plus the harness, Electric boost controller/solenoid, special o2 sensors, air/fuel ratio module and stuff it will be just shy of $4,000. But it's the only stand alone that can provide boost-by-MPH. Not even the Haltech stand alone offers that. Boost-by-MPH is apparently superior to boost-by-gear, which you can get through a simple boost controller like AMS and boost leash. Because I want to most advanceD traction and boost control, and because this IS A 1,200 Rwhp twin turbo car, I will benefit from a stand alone ECU to be able to tune the car better and make it more drivable than the stock ECU is capable of providing.
I'm either going to buy it from Induction Performance in FL or Undercover Performance in NJ, depending on who gives the better price.


That's all I know. Does anyone have any input or opinions here? Anyone know a better place to buy this?

 

I highly suggest D3PE for your ProEFI install. They do them all the time. Mine works great, keeps a ZR1 on 18s stock suspension hooked up making 830whp and 1100whp on spray. As you can see here.

 

+1 making 1450 on a 128. D3pe installed

 

The newer 112 will work on any Vette 06+ but needs and injector driver, for most applications. This is from a conversation I had with Chris at D3PE. Not worth it to change from my 128 for sure.

 

Gotcha. I'll just pay the extra $800 for the 128 and be done with it.

 

Nice pic! Unfortunately, I live in NY, so bringing my car all the way to Houston for a tune isn't a viable option for me.

 

Thanks! Are you going to do the install yourself?

 

Hell no! I'm completely ignorant with these things. I wish I was handy like that though. Is this stand alone something that any good tuner can tune well? My tuner JTM is absolutely fantastic at tuning cars on his Mustang Dyno. All my friends go to him and he works wonders. However, he doesn't have experience with Pro EFI. Is this going to be an issue?

 

More than likely yes. That is why I suggested D3. The program itself seems to make sense to me and is not super complicated but a lot of people end up ditching the system because they can not figure out how to get it to work. That is the reason I picked D3 with my build. I found the people who are the best at what I needed. If the shop you take it to can get the install right you could always pay Chris to come to you and tune the car. He did that for a few Vengeance Racing builds. Also if you do plan on getting him to tune it I would suggest talking to them before so they can give some advice on how to install it properly.

 

Pick a tuner, and use what he wants. Find a good proefi tuner can be tough.

For a build like this, shipping the car to d3 should be an option.

 

Well I did the install myself, but I don't think it is for most DIYer's. As far as the tuning its not too bad, but the initial set up is kind of confusing for certain things. And you could definitely get Chris to tune it via Teamviewer as well. Probably cheaper that way. GL!

 

Isn't the aem infinity a good option as well???

 

Anyone know a good Pro EFI tuner in the northeast? I'd prefer to just get a base tune emailed to me, then drive it to a competent Pro EFI tuner and drive it back home that same day or weekend.

 

Who is Chris?

 

D3pe

 

Yeah what he said LOL! Chris Delgato one of the owners of D3PE and is probably one of the best if not the best Pro EFI tuners. Tuning it tuning, but knowing your way around the software definitely makes a HUGE difference. I tuned all my own stuff prior to the Pro EFI. And only now after a year am I starting to get comfortable with the system and Chris has been critical to fixing things and explaining the way the software works. So 99.9% of it is still the tune that Chris has done.
