Don't tell me that. Are you saying that it will be a while before they come out with a FED spec chip? Meaning that I won't be able to bump my rev limiter for a while? I really don't give a crap about a max speed limiter removal, I just need my rev limiter pushed to about 7200 rpm; however, I would like the limiter pushed to 7500, if at all possible.

 

Yeah, honestly as slow as the cali-spec is going UNLESS something changes, it could take AT LEAST a month or two to crank out a fed-spec assuming pretty much the same.

 

i am convinced my ae has a limiter. in real world conditions, i cannot go past 130 no matter the condition or how much road i have left. blubyu2k2 has the same condition in his 2k2 auto. on my first and only dyno run, if memory serves me right, i hit 132 in 3rd gear which is why i want to whind out on 4th gear to see where i can get it. when i hit what i believe is the limiter, it will simply not pull anymore and this was done with stock tires, then 235-50-17 and now with my 245-45-17.

 

There is no way you hit 132 in 3rd gear. The gearing only allows for about 98 mph - at that point you will hit the rev limiter (different than a speed limiter). In fact, I believe that 128 is max mph in 4th gear - although I may be wrong about that one.

As for the speed limiter - it doesn't matter what tires you have now - only what tires the car came with. I do not have the 130 issue (as far as I know of course).

 

runviewer shows 132 and i only dynoed in 3rd to redline. the reason i listed tire size was speedo error, not saying it affected the limiter. edit-i am auto by the way, i thought everyone would pick up on that since i dynoed in 3rd.

 

i think sloppy is an auto? im a auto as well and know that i can hit 115 in third poss higher, i ran out of road

 

He has an Auto and it will hit 132 dyno proven in 3rd gear. Hopefully you looked over the part that he has an Automatic and not a 5 speed.

Matt

 

Yeah if hes an auto he can hit about 129-130ish in 3rd gear, after that you only have like 5 miles per hour more til you hit the damn limiter (in 4th gear, just to clarify that i wasnt going 135 in 3rd) in the auto...or at least i do, i hit my limiter at 135...

 

yea i also hit around 120mph in 3rd gear before i backed off...it was still pulling hard though...i'm sure if my car was lower and more road i could get some decent numbers in the 130s like you guys.

 

We're talking about 5spds...not autos.

 

i was just trying to compare the same year max's with different trannies. you said 2k-2k1 max with 17's has no speed limiter and that is not correct. i have a limiter in real world conditions @130 just as blu has in his 2k2 auto that had factory 17's. before max gator posted, maybe he should have wondered why i was dynoing in 3rd gear and could have even looked at my homepage. if i was going to call someone out and say you cannot do something, then i would have made sure i knew what i was talking about.

 

Sorry. My bad.

Can't seem to get straight who has a 5sp and who has an auto. Said that mad2kmax had an auto yesterday :

Ice was talking about 5spd since he was responding to mad2kmax. Anyway, ALL autos have a speed limiter. The only 2k/2k1 maximas that don't are 5spds with stock 17" wheels.

 

that last statement clears it all up. hopefully ts will be able to figure out the 2k-2k1 auto programming wont end up like the 2k2 auto one.

 

any of you that have removed the restrictor and noticed the lowend loss, do you all have under drive pulleys on your car???. I will be removing mine this weekend and wondering if the pulley will catch that low end loss???

 

lighter wheels, udp and timing advance have helped me in the low end. maybe these are offsetting any possible low end loss with removing the plate since i have not felt any loss.

 

I know that is called a "torque step", but I have no idea as to what purpose it serves. I had a "torque step" on my Dodge Dakota as well (4.7L SOHC V8), but I removed it when I opened up the TB to 71mm (up from the stock 65mm bore). I also replaced the throttle blade with a thinner one, used a smaller diameter pivot shaft, and countersunk screws to maximize airflow. Why spend $400+ on an aftermarket unit when you can do all that to the stock one....

 

U can reprogram the ECU via Consult II with the 17" tire program to eliminate the speed limiter. All 5spds have the same ECU, difference is all in the programing. When reprograming the ECU it asks ya if the car has V-Rated tires. My GXE with no speed limiter stopped pulling at 155MPH. I removed the restrictor plate, and I find no extra noise or anything different. Car runs the same way it ran before.

 

How long can you borrow the Consult-II?

Also, have you attempted to bump timing to 17-degrees, then performed an IAVL procedure, and finally to 20-degrees?

 

That would be SO freaking awesome if somebody reverse engineered the Consult-II's protocol and implemented its functionality into an OBD-II scantool.

(sorry, random offtopic remark, but wouldn't that just freaking ROCK?)

 

I *WILL* own a Consult-II someday...even if I have to steal it from my techs cold dead hands~!

 

But who will do the killing?

 

Doesnt Sammy the Bull use to live in AZ?

 

JOo mama~!

 

I dont think U going to gain anything from going to 20 deg- not sure if I wanna try it eighter. I know SRs love 17 deg vs 15 stock, anything higher is a waste of time. I can give it a try.

 

It's within the 15+/-5degree spec.

I just want to know *IF* it is possible, since NOBODY has tried performing the IAVL procedure once they hit the ECU 17degree wall.

That way I can either A)STFU or B).

 

Just wanted to let yall know that I just removed the restrictor and I did not notice a loss on the low end maybey due to the UD pulley. The high end is great and the sound increased a little. nice mod I.M.O. Took all of 5-10 mins to remove. very easy!

 

ok, i tried the second plate and the only change i noticed is that the cars boggs out at lower rpm, but take her for a highway run, and hold on to yourbutts. my g/f agreed with the final decision considering i raced her IS300 before and after and there was a significant change in where she was hanging with my car. before i removed the restrictor, i would keep pulling on her, when i replaced it with the widened plate, she would hang with me up until about 80-85 then i would pull disgustingly.

 

Auto 2002+'s have limiters...I know mine does.

 

When I get some free time this week, I will attempt to go to 20^BTDC timing. If not this week, then most likely next week...

EDIT- Now I just need to find the IAVL procedures on my work/home computer...

 

the 6 speeds also have limiters...SR20DEN proved that on the dyno, so for those that claimed to go past 148-149 is just speedo error. If I ever get on the dyno again I will see what the limiter on the auto is. I know the gaining basically comes to a halt at around 130 on the speedo but I'd like to see exactly what it is dyno verified.

Thanks...I finally found them on my home PC

 

hey guys, bumping an old thread for a new question...will us 5.5th gen guys benefit, or even be able to do this mod? this was brought up in another thread, and me and a few other members are curious now.

 

im almost positive this plate is not in the 3.5 intake manifold.

 

ok, back to the topic.......

first i cant belive the butt dynos here, common how are u gonna feel 2 hp on our cars, u feel 2 hp on a bicyle, not a 200hp car.

second i would hightly doubt, but wish its true, that this can give u in excess of 1-2 hp.

third, i do think it will take a little bit away from low end torque and hp, just like the case of the stock intake sesinator box (but this is really on the 4th gen not 5th)

and lastly, to contridict myself, its possible that i felt a slight loss at low end and smoother revs at high rpms, didnt feel any increase tho, but hope it did something for the better. i would not want to sacrifise low end torque to gain 1-2 hp at 5 or 6k rpms. by the way there is a much louder whistle now (which may be from a new kn filter-with no oil) but i think i kinda like the sound. lets hear from others that have done this

and one question, did anyone repace the rubber tb-manifold gasket when taking it apart? i saw a new gasket and its a good 2mm thikker than an old one, i guess they get compressed over time and may cause vacume leak issues.

 

Ok, I guess I'm the latest one to do this.

I did this at 5:00 and had to go to work at 5:30.

Anyways, I took off the ribbed rubber pipe that links the resonator to the TB (I have stock intake) and I took off the 4 screws securing the TB to the whatever the thing is behind it. I took off my TB and it would come out about 2-3 inches and then it would not go anymore. I tried to take off the restrictor plate but the damn TB was in my way. So I angled the TB in a way that I could *barely* get the damn plate out. Once I got it out it was already 5:25. I put the stupid ribbed pipe back on the TB but had trouble putting it back on the resonator, it was half on the resonator.

So I went to work, on the way, I floored it (keep in mind the pipe is not secured) I bogged like crazy low end and then once it reaches 3500-4000 rpm, it accellerates like crazy.

I got home like now and I took the ribbed pipe off completely to play around with it, I turned the car on and I revved it from under the hood, lol, it's funny because the MAF is not connected, it goes to to a certain RPM and stays there no matter how much you rev it.

Anyways, I hooked up my ribbed pipe and finished the mod, went outside, to the butt-dyno. From what I feel, It sure does make more noise, but I don't know about what kind of "whistling" you guys are talking about.

The verdict: No low-end loss. Maximum 1hp gain from what I feel. Sure does make more noise though.

 

I take back my "I don't know about what kind of "whistling" you guys are talking about" It whistles like crazy about 2000-2500 RPM.

I just bought a midpipe from the good folks at Berk.

 

How did you take the ribbed pipe off? I sqeezed it until I could squeez it no more and it still won't come off. I think I gotta take the whole stock air intake off.

 

There's a clamp on it , It fits pretty darn snug, you have to fight it.

 

Yeah two metal clamps, one on each side, I donna, there is no room to squeeze it out. I'll try again later.
