I have done some research on some of the other Nissan websites and have found out that in the 200 & 240 there is a speed limiter wire that can be cut to get rid of the top end cap.
Does anyone know if there is one on our maximas. I am still doing some research, but wondered if there was anyone with great electrical experience that might be able to find it also.
If we can find it it would be alot cheaper then some of these other options sold.

 

don't know about cutting any wires but I think an RSM should remove the speed limiter.

but don't quote me on that

 

Our limiter is in the ECU. Unless you want to cut the ECU power and take out the battery our limiter can only be removed or "modified" by the Rev Speed Limiter addition. BTW..your car won't run without the ECU, HAHAHA

 

Tahnks! Now you tell me. I just cut the power to my ECU and trew it away....that explains my car not running.

 

I'm almost 100% positive that 2k+ maximas are drag limited and not governed. I know 2k-2k1s are for sure.

 

What do you mean by drag limited?

 

The car cant pull through the air any harder, thus drag limited. Oh and its only the SE for sure that doesnt have a governor.

 

No I don't think that I have that problem...it just stops pulling all of the sudden. I even followed a friend with a Viper and kept right on his tail (with him letting me) and about 130 nothing it just stopped pulling. I thought it might be aerodynamics also.

 

other recent posts around here say (prove?) all autos are limited in the ECU at about 130 and 6-speeds are drag limited somewhere in the 150s.

 

So the drag limit is in the ECU? I am now very confused...I thought the drag was the actual wind stopping the car from going any faster.

 

drag *is* the wind stopping the car from accelerating, but before it gets to that point the ECU (in an auto) stops it at 130.

OK now that we have all that settled. I there a wire than can be cut like in the 200-240 or will the APEXI rev/speed unit remove the top speed limit?

 

not true at all. Ive hit 140 and I ran out of road, but was still pulling. I probably wouldnt have gotten much faster, but who knows.

 

this one is going to turn into the new "89 octane is just as good as 91 octane" war... some say autos are ECU limited to 130/133 other say only GLE/GXE are limited.

1. I have a 6-speed so I don't care.
2. I have no desire to go 140 so I don't care

How about I'll take some initiative and contact Nissan and find out the OFFICIAL story. It's sunday today, so it'll take a couple of days.

 

The SE autos aren't limited to 130 because I've gone faster in mine (both). Also, I tried contacting Nissan and talked to one guy (who had no idea what he was talking about - he said the NHTSA limits cars based on handling tests - I called the NHTSA and they'd never heard of that concept). I've also sent an e-mail to Nissan, but no response. Maybe they're not eager to tell us and have people test it...

Anyway, the tire speed limitation (car limited to max speed of the tires) is the best explanation I've heard so far. (seriously - my 4-year-old wanted me to click the "laughing" smilie )

 

Knock yourself out.

 

I can confirm a 2000 SE 5-speed is drag limited. I've done it. I got up to 141 (227 km/h here in Canada). This was speedometer reading so probably more like 130-135 mph. At that point, air viscosity and density probably affects it by a few mph so individual results most likely differ.

 

Haven't posted in a few months...been too busy on the Snowmobile...this thread caught my attention b/c I had asked about this last spring...My wife's 02 SE auto will run right up to 130+/- and then just die...it holds the speed...but no more...This is the same thing as my 03 Z71 truck...it pulls like a monster up to 100 and then dies...it's ECU limited to 100...

What puzzles me here is that if you ask this forum about this question, and 10 replies come in from SE auto owners, you will get 5 people saying they have been way over 130 and 5 of us who hit the brick wall...

Hopefully someone comes up with the true scoop, and better yet, a way for us, who do hit the wall, to get around it.

 

I'm not saying I know about "all" Maximas, but my 2K1 auto SE/AE has a speed limiter built in. Guaranteed. I get anywhere near 132-133 mph on the speedometer and the power cuts off. If I keep my foot on the accelerator the power will automatically "kick in" again around 125 and then cut out again at 132-133. It'll cycle back and forth like that forever. I don't like it one bit.

don't be so sure about that..

an APEXi RSM will remove your speed limiter...if you really really really really want to go that fast.

 

hmm.for some reason 2k2 6 speeds dont have that problem...

 

me too!

 

I did hit 140...once...out in Western, MA going down a big hill section of Rt. 91 between Rt. 2 and and Holyoke...that was it though...every other time...garaunteed...it dies out right above 130...no problem getting there...but dies out...my wife's 02 gets there a lot easier and quicker (of course) but the same thing...dies at 130+/-...we both have the V-Rated 17" rims...so I have no idea...her car, going down hill, up hill what ever...will not go over that 130 +/- wall...so there is definitely a Governer of some sorts on our two cars anyway...

Now what are the details on this APEXi RSM? Reliability, installation,known drawbacks/problems, price? Thanks for any help.
