    • E46 M3 and S54 turbo options set to open up thanks to ProEFI and the Pro128 computer

      Let's be honest, the S54 turbo scene has been dominated by Horsepower Freaks. That is not necesassrily a bad thing as they are a high quality option. However, there have not been any tuning options for those wanting to do their own turbo kit or perhaps go in a different direction. Well, ProEFI may be shaking things up considerably. ProEFI has released some initial details of their E46 M3 turbo setup using the Pro128 computer.

      As most of you know, the hardest part of doing a forced induction setup on a naturally aspirated BMW M motor is the tuning. Up until now HPF and their AEM setup was the only consistent solution for a turbo. Jason as ProEFI has demonstrated that an E46 M3 with a custom turbo setup (GT40) and a Pro128 computer has hit 573 whp at 9 psi on stock internals. Impressive? Yes.

      What are the specs on ProEFI's turbo M3? As follows:

      • GT40 Turbo with FMIC
      • E85

      • Flex Fuel Sensor allows for mixes of pump gas or E85

      • Traction Control

      • Stock clutch, exhaust, and intake manifold

      • 1000 cc injectors


      What does this all mean? Well, it means the S54 turbo market may be set to open up. This will no doubt drive costs down and allow for greater variety. Pricing information and further details will come for now we are incredible excited about the potential. Check out the video below:

        Here are some more details on the Pro 128 ECU and some pics, it retails for $2,199:

        Just so you know ProEFI is used on other platforms very successfully.

        Not familiar with them, so go ahead and share.

        It's actually a bit more complicated than that. The corn is grown in the midwest, however all of that corn has to go to refineries... (that oil companies own). So the problem isn't location by growth, it's population. The oil companies have been fighting this movement tooth and nail. Brazil uses 80 of it's fuel is sugar grown ethanol, the rest of their oil is domestic except for like 5%. They went that route during oil embargoes years ago. The oil companies know the potential for loss of sales on their end, so they have been fighting it like crazy. One of my friends owns 14 gas stations in the Phoenix area, and he has been trying to get approval to put in Ethanol at stations HE OWNES for several years. Only as of mid 2010 was he finally successful. The Obama administration is mandating more growth in this area, so the oil companies aren't able to carrie as much clout to prevent it. You will see them more and more in the higher populated states very soon. We have them pretty readily available now, and a year ago...you couldn't get it. You can purchase 55 gallon drums of E100 from you racing fuel supplier...it's still under $3 a gallon, and waaaaaayyyy cheaper than race gas. Sucks to have to pump it in your garage...but it is an option.

        That is the idea! Click here to enlarge I was going to take some video of the traction control in action, but I am going to have to put that off until I get a clutch in the car. So that is next. I think while I am at it, I am going to put a fuel system in the car as well, then I can put down some real numbers! Click here to enlarge

        One of the initial gripes I heard about the proEFI was the dealer vs customer software (the customer software being limited to more of the basics). Is this still the case? For example, from watching your knock-control videos, it looks like you've setup the proEFI to retard timing and add fuel within a range of values based on the severity of the knock (minor knock looked like 2* retard and 15% more fuel). But within a few seconds it seemed to go back to base timing.

        Is it correct to assume that with the dealer software, a tuner could increase the time delay it takes to return to base timing/fuel -- but someone using the consumer software could not?

        You can make a change to every table and option you want with the user software. The dealer software is required because it automatically configures itself for new firmware updates. The user software has to be coded to read new options and so forth. So Dealers are required to have the dealer software for that reason. If they request a change and need to test it, the new changes won't show up in the user software. They get put in the user software when the changes are validated working properly. You aren't 'Locked' out of ANYTHING you need access to.

        I only use the dealer software when I am developing a new platform that requires multiple firmware changes daily testing different strategies. An example would be how we handle the SMG shift torque management. I went through about a dozen iterations of torque management strategies to come up with the one the works on ALL shift settings 1- 6, and manual modes. From a tuning stand point... I only use the user software. Maybe we should rename the user software to just ProEFI software, and the dealer software to basic plain and boring software. Click here to enlarge The user software is 1000times nicer than the dealer software.

        Just poked around a bit with the user software and it does seem plenty capable. Seeing user-defined turbo shaft speed error logic/actions makes me want to take a closer look at the new EFR turbos too...

        Jason, could this setup work with a S/C? I know the boost adjustability wont happen but I was thinking about running larger injectors a T-trim blower and take advantage of E85. Your thoughts?

        Yep, this is the main option, getting it in a large drum from your race fuel dealer. Not bad necessarily, but not as convenient as having it at pumps.

        I understand the reason why the oil companies would fight it but that still would not explain why concentration is in the states that grow it. Logical correlation would suggest the reason it is so big in the midwest is due to the corn being grown there. If refineries are the problem why does the midwest get to much and the West Coast for example gets a handful? Ethanol can be shipped once it leaves a refinery as obviously the E85 that reaches pumps in the MidWest had to go to one.

        This just gets better and better.

        Would you mind sharing though whose manifold you are using? Would definitely like some pics of your engine bay as well. You can't post or upload pics being a guest vendor but I would gladly post them for you if you e-mail me with them.

        It's because those are agricultural places, so the Co-ops have all the incentives, and the populations are small. So the Oil companies basically let that slide rather than fight it.

        I am using the stock intake manifold! Click here to enlarge It's a lot stronger than people think! Click here to enlarge I have had 15psi of boost through it without any issues at all. Unfortunately I didn't have enough pump to take that one to redline or it would have made some real power!

        I know you are, I just want to take a peek under your hood Click here to enlarge

        This setup sounds like it will be cost effective, really a great development.

        Great news! e85 is pretty nice.. Poor mans race gas lol...

        Jason, have you thought about trying some E98 just for $#@!s?

        The other good thing i like about this is you race your cars, so im sure once you get a clutch in that thing it might be the first E46 M3 in the 10's?? hurry up lol

        We have a few stations around here with E85, I still haven't ruled it out of the new setup. An LS motor on ethanol should allow for some good numbers.
