Anyone know of an approved speed limiter for automatics??? I've pretty much narrowed down everything except this one last detail. :frustration: Any assistance would be greatly appreciated!!!
MSD has some really awesome stuff. i prefer the 6AL multiple spark discharge system that you could plug a limiter into, but that get spendy real quick. this http://www.msdignition.com/product.aspx?id=6935 might be more up your alley... just a simple rev limiter. if the rpm doesn't help since there are only a couple selections you could browse their site and look for something better. i know there was another company a few years back selling something that was a simple adjustable rev limiter, but i can't remember who it was... mallory ignition maybe?
Speed limiter for an automatic transmission LiveFreeOrDie, why are you trying to limit the speed and at what speed are you trying to limit it to? With an AT these variables will come into play. If for example you are trying to limit your truck to ~25mph you can't go with a simple rev limiter. Figure your rpm in the top gear your tranny will shift to at 25mph (12-1600 rpm?). Now consider how much power you will have available to start out in first gear with only 12-1600rpm - not much. The higher top speed/rpm that you are limiting it to via rev limiter will lesson this effect in starting off in first gear (more available rpm/power). If this is all you are looking at just mount an adjustable stop under your accelerator pedal. Unfortunately you don't have the luxury of locking out the higher gears in the fashion of the traditional import method (a slotted plate restricting you to physically shift into 1st and rev only). I think it would be necessary to get something similar to the US version of the kei trucks - but then you are talking about a fairly complicated combination of rev limiter, speed reed switch, vehicle speed limit control relay, fuel cut solenoid valve on carb, fuel pump control unit....etc. Probably not feasible or worth the time/$$$. It is an interesting project, I wish I had some info that would help, good luck and let us know how you solve it.......later, slim (this post has not been B.S. checked - yet)
slim, you make a good point on the rev limiter, but the other problem you may run into along the same lines is that the engine may not even reach a high enough rpm to shift into 2nd gear when liimited for 3rd gear speed. and, if all you want to do is pass an inspection, i would just loosen up the throttle linkage or put a nut and bolt limiter beneath gas pedal and run it through.
If this is for importing purposes then you will HAVE to have it EPA approved. Even if it works just like you want and it keeps it below the safe speed the EPA still doesn't have a approved method. But I also haven't checked in a long time either though. I see others with these autos and wonder how the heck they got over here. I myself wouldn't chance a container seizure for automatic trucks without making sure ALL is good. But that is just my rambling. Darin
Darin is hitting the nail on the head. I'm sure the powers that be are the same in the USA as Canada, it's not what will work that's important - it's what will satisfy them (EPA as Darin suggested) I would touch base with them to see if what you come up with will fly with them - remember it sometimes doesn't matter how sound or techinically correct your idea is if it doesn't fall within their parameters then they will say no more often than not.
This is to simply get it into the country at which point it would be removed. From my brief and extremely non-informative discussion with a customs agent in Dallas (real shocker there, eh?) I did manage to gather one piece of information and that was this: If the limiter was designed or approved for use for the vehicle by the manufacturer, it would clear customs. Do I trust this? Not without further verification to be sure. But it would stand to reason that that type of limiter exists. Weren't there some 25 mph LHD Hijets that Daihatsu brought over? It would be nice to find out if there is a Suzuki spec limiter/governor that could be installed on these vehicles. One last thing. With all of the chip modification going on out there, I'm surprised that no one has come up with a way to reprogram the shift points to where everything above X RPM in second gear is off limits. Yes, you would have to buy a chip or reprogram it, and yes it would hardly be a permanent governor. But then again, if I buy a manual transmission, I'm only a grinder and a few disappearing spot welds away from "reprogramming" it the hard way.
speed restrictor you guys have missed out. the e.p.a. says they have never approved the a/t for importation. they say they can not be restricted to 25mph. i had 3 trks. sent to the shredder and my broker told me another importer had 3 containers of a/t trks. sent to the shredder. be careful; customs has stepped up their exams by 20% as of last month. the e.p.a. hates mini trks.
Well it has been over a year since the last post, has the EPA approved a speed limiter for Automatic's yet?
