Found what could be the one hopefully
I'm unsure if you have owned/driven these car before. If not, be very cautious about using cruise control, especially on a wet road, and especially if your tires are old or worn. You can lose the rear end real quick if cruise is on and you lose traction.,
Thar would've been some good info to have to know about the motor. I will say that the motor feels damn good & 1st time in VTEC in 5th gear was awesome!
I have driven one before awhile go, this is my 1st actually owning one. Thanks for the tip & I did drive though some rain on my way back home w/o issue. Does the issue still exist even when there is VSA in MY06?
You back home with the car?
1. VTEC in a stock car doesn't engage until 6000 rpm which is roughly 97mph in 5th gear!
2. Personally never had problems with cruise control engaged in the rain but I tend to disengage it for better throttle control. I recall loosing rear grip hitting Resume on a car long ago that was very light in the rear end. It was so light I put at least 100 pounds of weight in the rear in the winter. But the S2000 is very balanced and VSA will probably control any tendency. As related here I took a right turn out of a car wash driveway and mashed the throttle in 1st gear and the rear end broke loose quicker than I could say "poop." VSA handled that quite nicely and that was 1st gear on a soapy road. I don't see an issue in higher gears at less than WOT. Get used to the car and drive accordingly. VSA defaults to On.
3. Do a valve adjustment at your first opportunity. Set to the high end of the spec for Intake and 0.001" looser than spec for the exhaust.

1. I guess I was too busy looking where I was headed & for the police. LOL
2. Is the VSA on the S the same as I know it to be like on the 8th gen Civic? Even when "disengaged" by the button it's not fully off.
3. The valve adjustment is definitely planned & it will be done by a person who used to be one of two Master Techs at the dealer where I purchased my Civic Si.My car will be in good hands.
I can't comment re effectiveness of VSA regarding use of cruise control on wet roads with bad tires. I can say that without VSA (ala ap1) its not a good idea. Bad things can happen really fast.
Glad it worked out! Enjoy your car.

To my knowledge VSA Off is Off and I've no idea how it works in a Civic, my last being sometime in the 1980s.
Honda worked for years to dial out unexpected oversteer from the S2000 by suspension, steering ratio, wheel size, and tire tweaks adding VSA in 2006. In theory increasing the rear tire width to 255 will dial out a little bit more but not induce understeer. I'm running this tire setup (215 front, 255 rear) and don't notice any handling abnormalities. Not driven on a skid pad though but my major VSA engagement on the soapy road was with these tires and VSA-On like it always is by default.
What tires are on the car and how old are they? This car is highly sensitive to tire pressure and sidewall stiffness. Nothing below Max summer tires is recommended. My car had Dunlop Extreme summer tires when I bought it which I replaced in a few months with Bridgestone RE-11A (extremes) and a couple years later with Bridgestone S-04 (max) tires -- no handling changes noted with any of the 3 sets based on my driving which my wife insists is too fast but is pretty docile.
Extreme summer tires can have horrible tread noise. You'll get more tire advice here than, possibly, engine oil advice.
You can drop VTEC to 3600rpm with a FlashPro tune and a high flow cat. Radically improves mid-rpm torque and power.

Can concur.
01 AP1 here. Cruise control on wet roads is a no no.
Between the bumpsteer, and the cruise control letting on and off the gas to maintain speed, it unsettles the car, and any unsettling that makes the rear loose any grip is scary.
Best to keep your foot on the pedal to keep the rear planted down.
I've driven a couple of 08/09s and driven a couple CRs, even with VSA off, they don't have this issue due to the suspension changes.
- upper control arms
- spring/sway rates are reversed.
Which makes the later models a "better" daily driver. But I just avoid the rain, because the AP1 rotates and is more fun when it's dry, faster steering rack, the bumpsteer is actually really nice to rotate the car once you "know" how it reacts you can use it to your advantage.
