Yes, you can do it on both units however because the flexfuel sensor has a frequency output and the 48 unit does not have a frequency input, you need to purchase this:

This unit converts the frequency output to a linear analog output that the 48 unit can process.

Well my car has been a nightmare from the beginning. Some of the issues have been resolved now. I guess I'll wait for the updates mentioned above before I give an updated list of problems with the software, since some of them may be resolved with the updates.

Well the cost of the GM Flex Fuel sensor is outrageous, and on top of that I would probably buy the 128
I dont drive my car in the winter so the E85 is pretty consistent during the summer months, i would look into it if I switch between pump gas and E-85 but I don't

Im going for E85 and currently have Haltec, but I'm so impressed that I'm reddy to go for ProEFI. I'm i Sweden so I dont care about emission and my goal is a track day car capable of strret driving. Shooting for +800whp. What do I need 48 or 128 pin and CAN gauge and what more? Bolt on?
EDIT: How is the flexi fuel funtion tuned?, closed loop?, end-user friendly?

You can do flex fuel with either unit. If you get the 128 unit, you will get things like dual internal widebands so each bank could be monitored individually. Wheel speed traction control, knock control and many more inputs/outputs.
You can do Drive by wire and the variable cams with either unit.
I always suggest tuning with the car in open loop, then turning it on for minor automatic adjustments .

Awesome work. So with the traction control feature activated you can be the worst driver and still make some really good times down the 1/4 mile. LOL!!!
This must be something that can or will be able to be turned on/off? How else would you heat up the tires with the Traction control feature on all the time?
I want the traction control feature with my tune Larry! Looks incredible!!!

There is a switch on the dash to turn it on or off!! Also we can hook it up so that if you are on the brake or line lock, it turns off automatically.
You should do the flex fuel on your car Randy and get rid of the Meth kit. Much safer!!

I would Larry, but the closest E85 station is +30 miles from me.
...EDIT...Just found a station less than 10 miles away. Now i have to research the benefits and prices to converting.
Hate to admit, but I have todo my research on E-85. Most likely I will stick with my current set-up.

There really is no tuning for the flex fuel function. Just turn it on the the ProEFI pretty much does the rest. It is just simple math based on Ethanol content to figure out the required fuel needed. You will need to setup two timing tables, one for pure pump gas and one for pure E85 and then the computer interpolates between the two.

He want to do some research about this before he decides. Is there any good links?

The reason i put Supra Forums is because a lot of testing was done on the 2JZ-GTE platform. Just search ProEFI, and I'm sure you will find plenty of posts!!

For those too lazy to click on the link provided above, here is some of the info in that link...which I didn't know...
What's your ethanol percentage?
The ethanol content of E85 fuel can vary from 60% to 92% ethanol. A fill up with E85 can drastically change the mix of fuel in your vehicle. For performance drivers determining actual ethanol content of E85 is essential to maximizing an engine tune and horsepower.
Why know your ethanol percentage?
E85 has the equivalent octane rating of 105 octane gasoline. Higher octane fuel is more resistant to knock allowing for more aggressive ignition timing, higher compression and increased engine power over gasoline itself. The Zeitronix Ethanol Content Analyzer helps you get the most out of your engine and fuel.
