^^ Yet another good idea. I never thought of such an option. :bigtu:

Leave the MS in your car for now, but tell your competitors about it. Assuming you're not beating them (and I'd be surprised if you were, given it's your first event) they probably won't care. If they do care, then put "STR", "CSP", "SSM", or "OSP" (my favorite local class -- may not exist in your area) on the side of the car and mentally compare your times to the times in STS. It will likely take you at least a couple years to get fast enough to care about points (and more than that for national level events), use that time to think about what you want out the car and how best to prepare it.

Exactly my thoughts along with co-driving an already prepped car. Leave the MS in since you've only done one autox and you'll probably only do 1 event per month and driving the car on the street otherwise. If you really want to get creative I would create an autox map that simulates the stock power the stock ECU would produce and just use that map for autox if you want to eventually go to STS at National/Regional events.

Unfortunately, I removed the MS before the event and now I'm getting used to life without it. Sure I miss the extra torque but I like the civility of the stock ecu and the better mileage (which is more of an indictment on my tuning ability than the MS). I decided to sell it and use the money elsewhere. If there are no takers for the price I want, then I'll consider putting it back on. Thanks for all the suggestions though. I got some good ideas from you guys.

Have to run MS in stock box in STR as well :( Unless they changed that, because that would be awesome.

here's the rules for ST updated for 2012

F. The engine management system parameters and operation may be
modified only via the methods listed below. These allowances also
apply to forced induction cars, except that no changes to standard
boost levels, intercoolers, or boost controls are permitted. Boost
changes indirectly resulting from allowed modifications are permissible,
but directly altering or modifying the boost or turbo controls,
either mechanically or electronically, is strictly prohibited. Traction
control parameters may not be altered. Any standard OBD communications
port functionality must remain. The Check Engine Light
(CEL) or Malfunction Indicator Light (MIL) may be disabled via software.
Alternate software maps which violate these restrictions may
not be present during competition, regardless of activation.
1. Reprogrammed ECU (via hardware and/or software) may be used
in the standard housing.
2. Supplementary (“Piggyback”) ECU may be used subject to the
following restrictions:
a. Connects between the standard ECU/PCM and its wiring harness
only.
b. Must be plug-compatible with the standard ECU/PCM (no splices)

Oh, and you can change 1 sway bar and stay in e stock now.

OSP? Is this with NorCalUFO? I need to come out and play some more now that the car is "reliable" :giggle:

I run with UFO most of the time, yes. SFR SCCA also has an OSP class with the same set of minimal rules (basically, if it was at one point street registerable and it has DOT tires then you're good to go).
