Since altering boost controls is not legal in the street prepared classes of Solo 2, is the PFC legal?

Does the base map alter the duty cycle of the wastegate from stock? If not, then it should be legal. The fuel and timing alterations are fine.

Nope, because it has its own boost control that is not factory. And boost duty, target is not stock.

yeppers what he said

Is it possible to set the PFC to a legal ASP configuration? If not, I guess I can always run SM2.

reza

I don't think so, but would be interested in doing that as well.
The limiting factor is the boost control portion of PowerFC. If we can show that we don't let PowerFC control boost, but instead stock ECU that control boost. Maybe it will pass.
So running two ECU: One stock for taking care of boost, and one PowerFC for Fuel, etc.

You guys need to be more creative

rynberg

Why don't you guys just set the boost to 10 psi and unplug the commander? Are they actually going to pry off your kick panel to look for a stock ecu? If so, SCCA sucks even worse than I thought...

you gotta be honest when competing...Otherwise why compete if you want to cheat...

From people I know who have raced SCCA events for just about as long as I have been alive .... there are two kinds of racers; cheaters and losers. You have no chance at winning if you don't cheat because everyone else is cheating whether or not you realize it. In many classes I've heard of rules that keep your car from even being raceable because some rule was ridiculous. Just about everyone in the class ignored the rule and even the rules people looked the other way. I'm not big on cheating just for the record, however some stuff is just dumb.

As far as the class mentioned ... I personally know several people who have competed nationally and done this mod. Many are not even running RX-7s anymore because the Z06 is so dominate. (side note to DamonB: looks like you were right!) The intent of the rules are not to all more HP due to boost mods; hence giving turbo cars an unfair advantage. However, adding an intake & exhaust will raise the boost to 12psi. A legal fuel & ignition controller would help tune the car safely. So to go with the spirt of the rule, run a powerFC and tune safely for 12psi boost.

How is it cheating to run the same boost level as stock? I am a pretty honest person and I wouldn't feel the slightest bit bad about running a PFC at 10 psi.

I guess I just don't get the whole auto-x competition thing with all of it's restrictions....I wouldn't deny myself great car mods just to keep in a class. I only auto-x for Mazda Motorsports membership and to keep in shape for HPDE.

Hey Tyler,
any form of boost management other than stock is not legal for ASP. Although you may set the boost settings for 10PSI, that's only the peak, you cannot ensure that boost above or below the peak RPM is equivalent to the stock ecu. It's better just to move to SM2 anyways, the FD is more competitive in that class.

reza

Actually you can stay in ASP with stock ECU, open up the intake and exhaust. let the boost spike, creep to 14psi. This way you will be winning trophies...though it may cost you engines...

Actually, boost cut kicks in before 14psi.

RPM -- SEA LEVEL CUT OFF(PSI)

1000 - - 11.8
1500 - - 11.8
2000 - - 11.8
2500 - - 11.8
3000 - - 12.2
3500 - - 12.4
4000 - - 12.8
4500 - - 13.3
5000 - - 12.2
5500 - - 11.3
6000 - - 11.1
6500 - - 10.7
7000 - - 10.7

So if you boost creep becomes to much, it'll make for a very annoying car to AutoX

reza

its a fuel cut, not boost cut, to be more exact, the ECU cut the fuel delivery when boost reach certain limits in that chart.
The boost can go up, but no fuel, so the car stumble.
