•Fuel Injection to NASCAR in 2012: NASCAR is expected to announce Friday that the Sprint Cup Series will shift to fuel injection in time for the 2012 season-opening Daytona 500. It is expected that Britain's McLaren Electronic Systems will provide the controller through a partnership with Freescale Semiconductor, Inc. out of Austin, Texas. Testing and development of the components will continue throughout the year.(FoxSports)(2-11-2011)
UPDATE: NASCAR announced a historic technology partnership with Freescale Semiconductor and McLaren Electronic Systems to develop and integrate fuel injection systems into the NASCAR Sprint Cup Series, targeted for the 2012 season. Freescale will provide the processors for McLaren's engine control units (ECUs) that will be used to manage the fuel and ignition systems in the engines for all NASCAR Sprint Cup Series cars, replacing carburetors which have been used in the series since its inception in 1949. NASCAR and its top series teams will test the technology during the 2011 season with the anticipation of the systems being rolled out for the 2012 NASCAR Sprint Cup season. The fuel injection system will bring increased technology and efficiency to the NASCAR Sprint Cup cars while at the same time complementing the car's high performance. This announcement marks the most significant strategic change to NASCAR's engine platform in decades. As part of this program, Freescale is designated as the "Official Automotive Semiconductor of NASCAR" and McLaren the "Official Engine Control Unit of NASCAR."
For decades, most of the parts and equipment on NASCAR race cars have been highly customized for racing but at the same time relevant in standard automobiles. This move to fuel injection brings back an important synergy between these two vehicle types. ECUs maximize each racing team's ability to get the most performance and best fuel economy under all race conditions. With this announcement, plans call for every NASCAR Sprint Cup Series race team to use a control system with Freescale's advanced 32-bit Power Architecture based engine management processors at its core, beginning in 2012. These same processors power millions of today's most energy efficient engines.
The ECUs are tamper-proof, ensuring that only approved software may ever be run during a race weekend. Additionally, NASCAR will have special electronic tools at its disposal during every event to ensure the legality of all ECUs.(NASCAR)
AND Robin Pemberton, NASCAR vice president of competition, said during the news conference that Nationwide Series and the Camping World Truck Series will not be going to the fuel injection system in 2012 and that NASCAR is working on a new engine package for both series (Nancy/Jayski)(2-11-2011)
 
"The ECUs are tamper-proof..."

Yeah, until a 13 year old gets his hands on one!:D
 
Oh, i'm certain the shops have had them for awhile now, manipulating the hell out of them.
Thats probably why Gibbs' dyno blew up a few weeks ago.:growl:

If they ( nascar crews could manipulate them) don't you think that would of already be attempted in F1, where the technology and money spent on race teams far surpasses Nascar??

Well, maybe I mispoke. Not that they actually are, but i'm sure they're trying.
They wouldn't be engineers, and crew chiefs, if they didn't.
And, for all you know, maybe some F1 teams have found something......
You don't think McClaren would go public with any loopholes they might find, do you?

Lol no they wouldn't, but from what I have read F1 is pretty close to the vest when it comes to any form of cheating. I haven't heard of anything involving the FI system, but maybe it has happened.
 
Sounds to me as though they will use Throttle Body Injection which is only about ten years obsolete. Excuse me if I'm not overly impressed with NA__AR advancement.

I'm with you. If NASCAR want's to be relevant to today's technology, they are going to have to move to something like 1.8L turbos.

Until that happens, it's all window dressing.

This decision on F.I. was typical NA__AR, like their addressing the new race car (they hide the splitter and allow different decals of a basically generic race car) and the lack of racing (they change the point system?). NA__AR seems to be great at seeing a gaping wound and treating it with a bandage.
 
I can't imagine NASCAR running a TBI system. I'm thinking it will be a port injection type set up. Only time will tell. I am curious, though.

The problem is, how do you tech an injector? What are they going to do, run a padlocked cable through all 8 injectors like they do for sealed engines?

Not sure. I'm thinking if the injector is in the manifold port then maybe some type of marked, issued, sealed injector. Maybe they'll issue entire injection intake manifolds. Who knows? Regardless of the method of fuel injection used, NASCAR will have their work cut out for them during pre and post race tech inspection. I'll bet these crew chiefs can't wait to push the envelope and delve into the "gray" area.
 
Here's another thing, FI is going to require an electric fuel pump. Is there going to be an inertia switch. Will the inertia switch be within the driver's reach so the driver can reset the switch in the event of a minor collision?
 
We ran our pump thru a relay connected to the oil pressure sending unit.

I wonder if NASCAR will use that same method. So many possibilities and you know NASCAR will probably choose the least practical. At least the Waterman POS will be history.

was wondering the exact same thing the other day
