Default Another Controller Question

When going with a 400 amp controller, what kind of MPH increase should I see ?

Speaking with the guy at Controller Test Service, he said I'd see a 20% increase in torque with his rebuilt controller and probably a couple of MPH's more. Will the Alltrax give me more speed ?

Typically controllers will add torque. Increasing voltage will increase your MPH. You can run taller tires with the new controller and get a few MPH that way.

None. A controller will not add speed. It adds torque only.

Tires and volts will add speed.

Amps = torque.
Volts = speed.

You cannot add volts without changing the controller.

Got a speed chip on the way and I'm running 20" tires. I've been told my stock controller will fail soon on my PDS cart because of the bigger tires, lift kit and weight of the back seat.

Just a bit of friendly picking, but this statement is not necessarily true since there are multi-voltage controllers available. It's one of reasons I chose the Alltrax 7245. It will run voltage from 24 - 72 volts.

I also run a 48=72v controller. Be sure you match your volts to controller. Controllers are very voltage sensitive.

Sorry - you cannot run the stock controller with higher voltage than it was made for. I thought that was a foregone conclusion.

Decided to try the CTS 400 amp Controller because of the price ($220), but I'm not doing anything until my cart warranty expires. I'll let them replace it if it goes out in the 90 day period.

I'd like to have a AllTrax 400, but at $450 plus and all I'm getting is a 2 year warranty instead of a 1 year warranty and the ability to program it, I'd rather (need to) save the $$$$'s.

Last Monday $3400 for the cart including tax ('05 PDS, 5" lift, 20" Badland tires, fold down back seat and HD rear springs)
$481 this Tuesday for new Trojan Batteries and 4 ga cables(mine would have lasted thru the winter, but couldn't pass up the deal)
$6.50 for a speed chip Thursday
$20 for a steering wheel cover on Friday.
$781 for a trailer tomorrow (been needing one for my Lawnmower and stuff.)

wanting a golf cart has already cost me $4688.50!!!!!!!!

Then, don't cheap out on the controller. Rebuilts do not have a very good reputation.....the controller is one of the most important components of your drive system......save up and get a good one. IMHO

P.S.
look into Logisystem controllers

Tell me what buying the $450 one with a 2 year warranty and programmable will give me over the $220 one that has a 1 year warranty ? I'm open to buying the best, but I also need to know why it is best and what twice the money is actually giving me other than 2 times the warranty. If I buy a cheap one and it last 1 1/2 years and I replace it with another of the same, wouldn't $$$-wise that be about the same ?
