Has anyone used the AMS-500 boost controller I've seen alot of mention of this and the ams-1000 but haven't seen any feedback from someone that has actually used the 500. Does this unit need a laptop for programming? How's it compare to an eboost2?
https://ls1tech.com/forums/showthrea...hlight=ams-500 contact this guy.
Even the AMS1000 does not need a laptop. there is only if I rem correctly 3 stages of boost. Its pretty much the same as the AMS 1000 but less boost stages.

The AMS-500 Boost Controller can control 2-Stages and/or levels of boost. The 2-Stages are controlled by Input1 and Input2. Both of these inputs can be configured using a DIP Switch for either Ground or +12 volt activation. Input1 may be configured to function as a “Launch” stage when used in conjunction with Input2. Input2 offers an adjustable ramp rate as well as boost level settings.
Each stage has a range of adjustment from 0 to 40psi with 1psi resolution and is controlled to within .1psi to target using advanced control algorithms. If a setting greater than 40psi is configured the AMS-500 will default to the maximum 40psi allowed. A setting of 0 PSI will turn either stage off.
An optional Safe Mode is available when using a pressure source other than the manifold pressure. The Safe Mode continually checks for the proper pressure increase and will disable the system and open the decrease solenoid in the event of an error condition.
When in Normal Mode of operation the AMS-500 will keep trying to apply pressure to the waste gateuntil its target is reached.
IMPORTANT—The AMS-500 controls the pressure on the Waste Gate so the actual boost level obtained is a combination of the Waste Gate Spring pressure and pressure applied by the controller. (Just like the AMS-1000)

I just finished installing the ams 500 on my APS set-up. Hope I'll get a chance to test it out next weekend after I finish getting the 9" installed. Looks lke a nice unit, but we'll see. Anything has got to be better than the Turbosmart dual stage that I tried.
Updates? I am stuck between the 500 and 1000?
Which one would I benefit from more? Single S91MM car that is 3600lbs. TH400 Auto. Am I going to gain more from the added price?

So far the AMS-500 has been working great. Very easy to to install and configure. Right now I'm only running 1 stage, but I run off the wastegate spring on the street. I plan on making 2nd stage for race gas and 18-19psi.
If its a dedicated strip car I would probably go with the 1000 because it can do so much more.

If you have your boost controller switched you can actually control 3 levels off boost. Whatever you waste gate spring is running then whatever levels of boost you have programmed on stage one and stage too. Very simple to install and operate. Going to be testing mine soon. I have never used one before but fairly simple.
What im saying is that from the diagrams that i have seen of the setups of the AMS-500 is that it doesn't even tap into the intake or anything for a boost source when you use the CO2 method. If that is the case then all its doing is applying the pressure you tell it to and it doesn't fluctuate on its own.
Im guessing that there is something that I am missing. I cant imagine that the AMS-500 cant do any thinking on its own. At least I hope that isnt the case. Like I said I could be retarded and missing the whole point.
Thanks!

This is the install manual from NLR. I dont see anything that would tell teh controller what boost the engine has going to it. So wouldnt it be applying a static pressure that you set?
I guess what Im asking is that how can this be super accurate if all its able to be accurate about is the pressure applied to the top and not whats goin into the engine like other controllers do?
I really like all that i hear about this controller but I wanna understand before I buy anything.
Thanks

Very interesting. One thing I was hoping when I was lookin at this controller for the first time was that I woud be able to have it keep MY boost in check. If it starts dropping or rising. As you say you havent seen them do anyhign but hold the psi you get it set at I guess there is some fuzzy logic in there that I dont understand.
Thanks!

look at the diagram again. A boost controller had to have a reference. On the right side of the controller you see MAP sensor 1/8 npt (thats your boost reference from your intake manifold). The AMS 500 regulates boost by controlling preassure to the top of the waste gate. It will keep your boost within a 10th of a 1psi. Its all you need. The way i understood it is that co2 is used to make boost off the line by holding the wastegate shut. The onlything this controller cant do it apply pressure to the bottom of your WG to run less boost than you spring applys pressure. Hope this helps.
That port on the side of the controller is for the top of the waste gate(s) reference. The boost controller pulses the solenoids(increase and decrease) to keep the programmed pressure the same actual pressure on top of the gate. The bottom of the waste gate reference can be tied into the intake manifold or compressor housing.
