msp topspeed

Better get it out of your system before Oct 1 2008 when HB137 becomes effective. Vehicle confiscation, fines and mandatory jail time are what is waiting for you if your caught then going 30 mph over. Right now you can be arrested for going 20+ mph over. All depends on the attitude of who pulls you over.

I'm not telling you what you should or shouldn't do, just pointing out how Florida treats excessive speed violations.
 
i got a question the governer on the car is there any way to take it off?? becouse i know i took it off a 240sx it has a tranny sensor and a wire from the ecu and all i did was cut the wire and unplug the sensor but idk if the msp might be the same
There is not a governor. Just fuel cut at 7200rpms.
 
Awesome post Rogue - exactly what I was talking about.

Fatti, how much boost are you running? You may actually be hitting fuel cut before rev-limit. I know on some cold days, even when fully warmed up, it'll cut out on me lower. The last time I was out tuning in March (it was still pretty cold) I couldn't get the car over 6500 RPM.

Also, according to my AFC, my tach display is off by about 200 RPM (tach reads higher). I don't know if this is just factory inaccuracy or if it's because I have an MSP cluster on a P5. They have different stock wheelsizes so is it possible the speedo/tach is off due to different stepper motors?

EDIT: just because people keep asking. THERE IS NO SPEED GOVERNOR ON THESE CARS!

Doubtful...but it may depend on whether or not the p5 has ABS.

MSP's read the speed using the ABS sensors, non-ABS protege's read speed by a gear on the differential.

Thanks for that info, I was just wondering why my speedo was 3 miles off with the MSP wheels yesterday. I figured the MSPs read the speed differently but hadn't searched yet.

I topped my 2003.5MSP at 135 mph, and left it there for over 1min, on the speed governor (speed cut), this is well below the rev limit in 5th. Here in Jamaica the traffic laws aren't as harsh.

Im running a lil over 10psi and i know that i have it a lil more rich towards the end just to keep a lil more safe for the motor so maybe im hitting fuel cut.

I also have heard alot about the stock tach being off, i have a stewart warner tach that i go by and it reads the same numbers as the AFC so i go by that most of time, and the AFC recomonds u using there tach too.

No prob.

Different wheels? Larger diameter wheels(tires) will throw off the speedo reading.

Well my car started out with 15's, but when I put on the 16" P5/ES wheels it was only off .5 of a mile. I went by a speed reader last night and it was saying 63 while my speedo read 60. Good thing I noticed before driving through a speed trap :)

Yeah, I've got ABS. However, the P5 and MSPs have different overall wheel sizes so I just didn't know if the stepper motor in the cluster is calibrated differently (you know, 3000 RPM in P5 tires would be slower than 3000 RPM in MSP tires).
