This is very interesting. I've always been one to make my own turbo kits for my previous various cars and tune it myself on the dyno, but I have opted not to on the M3 because of lack of end user tuning adjustability other than going through the HPF route which IMO is far too costly. This opens up a new window and I am tempted to start gathering parts to do something. Any estimated ETA of release?

We are going to be coming out with some cool new stuff for even bigger power numbers in the future. But I'm excited about possibly having two styles of HPF customers, one that want the capability to tune their own setups using ProEFI and one that wants it completely plug-n-play with the thousands of hours of tuning we have into our HPF/AEM EMS. I'm also excited about the competition this brings to the table and the variable option of customers running custom setups. They could use various parts of our kits and not others. This could turn the E46 M3 market into a market similar to the Supras.

Chris.
Chris, I'll try and give you a call tomorrow. Remember, this is an SMG!

Same deal. I don't have to worry about what I come across for fuel. I can take the car to vegas, put regular pump gas in on the way (no E85 on the trip). Then fill it up with E85 once I get there and go have fun!

Just to be clear... his silver race car still runs race gas. His black street car is on E85. It can be done though...I have made 1100hp to the wheels on E85 with a 3.0 liter Supra.

Congrats on the sponsorship! I don't even own an M3 and I found your video fascinating. That is a very cool piece of technology you are using in that car.

In the end of that video it states. e85 states easy see even in the dead of cold. But on the engine thermostate it's at engine operating temperatures. That is not quite a proper cold start. e85 at true 85% ethanol can be a ***** to start around 45F or less.

But of course if you use starter fluid injection into the manifold or a vacuumm line you are good to go.

He was stating it as a matter of fact, not saying it was cold at the time it started. If you want to see a video of a ProEFI start cold with E85, SP did one of a car there in CHicago where it gets cold.

what's the max pulsewidth proefi can do at priming/cranking pulse ? provided the injectors are large enough it doesn't have to be all that high for startup in the cold with e85.

amount of cranking to start depends on the amount of fuel you can inject on startup.

so does this thing talk whatever can protocol BMW cooked up for all the modules to get the sensor data from the traction control for the ABS data ?

for the record, cold start is a ***** to tune, regardless of the system, so all you stock-ecu people, be thankful you never have to deal with that ****. same goes for water temp and airtemp corrections. those are also a pain.

You can hang the injectors wide open if you think thats what it needs. Cold start really isn't that bad at all...because we have already done the hard work. I have a Dealer in Chicago (Sound Performance), that helps me do all the really cold stuff since I live in a place where it doesn't get cold. Most of the calbration work is handled by the computer. Since the ProEFI is a true volumetric efficiency based system, once you set up the engine size, fuel injectors, fuel pressure, etc.... that takes most of the work out of it.

This means that when you take a calibration from say a 2.0 liter 4 cylinder and put it in a 10.4 liter big block v8, you just change those few parameters along with the firing order, and the computer handles the rest. This gets you within about 15% of where you need to be right off the bat. One of the things I have done in some of the training classes is take a calibration right out of a Nissan 350Z, drop it in a Supra, change the firing order, engine size, and injector size. Then we hit it on the dyno at 20psi of boost on the first pull. The 2j isn't quite as efficient as the VQ, so it winds up being about 5 to 8% rich up to about 5krpm, and then from 5 to 7k it's about .3 a/f points off. However the car starts right up and idles nicely with just those changes.

Great hanging out with you today and going over the ProEFI kit and its capabilities. My car will be ready to go under the knife when the Prod kits show up.....
