Open ECU for next season is officially a go!

http://scca.com/documents/Club%20Rules/ImprovedTouring.pdf

Please list any other changes here so we can have them in one place :)

6. The engine management computer may be altered or
replaced. A throttle position sensor and its wiring may
be added or replaced. A MAP sensor and its wiring may
be added. Other existing sensors, excluding the stock air
metering device, may be substituted for equivalent units.

7. Wires and connectors in the engine wiring harness may be
modified or replaced.

Indeed.

You guys notice, of course, that the "wiring and connectors" part is an independent line from the ECU part, and is not restricted to only when you "alter or replace" the ECU...? Let your mind wander...

as near as i can tell, one could rewire/gut the whole engine harness if they were of such an inclination.

for replacement of existing sensors, what exactly does "equivalent" mean?

equal in specs, equal in size, equal in location, equal in function?

can i put in a wide-band O2 sensor for the stock one? my personal interpretation is yes based on the above and it does not seem to be a tortured interpretation. at least i wasn't gritting my teeth when i read it or typed this.

not sure if i need to or want to. i need to read the rest of the rules over the long weekend.

I'm just happy that there is no specification as to whether "engine management computer" is electrical or mechanical. Wait 'til yall see what CIS can do! :026:

Without electronic injectors, aren't we now officially screwed?

If a MAP sensor can be installed why in the world would one want the factory MAF left in placed(Does it has to be in working order?)

Thanks,

Think outside the box - stew on it a bit....


Why is 9.1.3.s still there?

s. The engine management computer or ECU may be altered
provided that all modifications are done within the original
housing.
 
But not me...one Motec powered 3.5 liter V8 Bosch L-Jetronic motor coming your way this spring or summer.

This could be good.
 
I suppose us carburetor guys can gut the engine wiring harness and save all that weight?

Yep. In fact, that is all it takes to keep the carburated cars competitive. A slight spec-line weight reduction, to account for the fact that the "process" must now change its weighting w/ respect to Injection vs carburated cars.
 
I guess I was hopping that us old carb guys would have a bone tossed our way. I guess I could go FI or ask for the carb rule to change and give us somethig a little better. Maybe a holley 350 or the Weber 38 or just be happy I can race and have fun chasing Pablo. Granted it will be harder to see him.
 
It looks like the "samelining" of the 85-88 ITA Fiero's made it in also. I continue to find it interesting that the ITA Fiero is samelined, but not the ITB Fiero. Doesn't hurt me, since i believe the my 88 is the best of the bunch, but seems pretty contradictory.

Contradictory, indeed. And yes, the '88 is clearly the car to have, in either class.

But the irony of this? The build of an '87 ITA car that prompted this change has been abandoned. :)
 
Guess what guys, the process used to spec the weight of injected cars assumes you can fit a full tilt booogie system in your stock box. This rule is to make it easier for you to actually do that...across the board. Some will find that their stock system actually works best, others find the diminishing returns not worth it as they have great chip options, and others will have fun with their laptops.

Now if you're complaining that it was better before, because it made people spend more, which means you saw fewer such systems, well that's your perspective. But delta Hp shouldn't bump up drastically as has been suggested here.

I know cars..... real cars that I share the track with....in ITB, ITA and ITS that have full on systems. You might too, but you didn't realize it.

Yes, Jake, you are correct. ie, the "process" should be spec'ing cars based on the ultimate build, and the ultimate build was whatever $100,000 of ECU you could fit in the stock enclosure. And yes, as we have hashed over and over, this rule change does make it easier for "everyone" to get those benefits.

However, why did we need to make this change? Because the perception was "only the privileged *few* could acquire that $100,000 custom ECU". So, are the carb cars currently on a par w/ those privileged *few* or the more widespread closer-to-stock ECU *many*? I would guess the latter, and that was the reason for my above statement. But, hell, i could be wrong.
