EZGO 2003 PDS SPeed CHip Placement

1986g3a · 06-01-2008, 08:54 PM

It is the same as checking the diagnostic code. The code that is Given will tell you that you have properly installed the chip. 4 beeps for the Red Freedom chip, 2 for the Blue Steep Hill chip, 3 for the Yellow Mild Hill chip. 1 beep means you have no chip programmed. Once you hear the beeps confirming you have installed the chip then you can take it out and still get the performance of the chip. If you purchase you cart from a dealer most of them will ask you if you want the upgrade and charge you for the chip. What they really do is reprogram the controller and keep the chip.

I just checked this info with an E-Z-Go tech, and he says you're right AND wrong.

It will work as you described UNTIL the switch is moved to the TOW position. Then when moved back to RUN the controller will default to the ALL TERRAIN setting.

This would surely upset the customer!

At the shop/dealership I work for we were told by the EZGO rep that the controller would not reset unless you lost your voltage coming from the batteries. But everytime I have installed one I alwlays leave it in. The customer paid for it.

You are in not reprogramming the controller. You also have to leave the plug in. I am with gorno...never heard of it done like that. Tow mode....unplug plastic plug with wires....plug in new plastic plug with wires.....put in run mode and your set. I don't know why they call it a "chip" when its a **** $1 plastic plug with some wires in it. What I really hate is these shady dealers and theiving guys on ebay who want to charge $50 for a part that cost $1 (or less) at any decent electronics dealer.

I have often thought of mass producing theese things and selling them for $10. You could make a killing. The only thing is, I wonder if there is a patent for it, I think thats how you spell it.

gornoman · 06-04-2008, 06:25 AM

They are $4 on ebay. (+ $5 S&H!)

Best I can tell, the chip has to stay in. Toggling the F/R switch to Reverse 5 times puts the controller in diagnostic mode and the first beeps tell you what chip is in the speed control slot, according to the service manual. Have never heard the chip doesns't have to stay in, as all but the "all terrain" chip have wires. However, the all terrain is just an open plug, so it might be that the controller is programable, but it is an E-Z-GO secret, as it is not addressed in the Service Manual.

I would like to confirm this, as well. Not disputing it is programmable, but just never heard that. Always see the chip in the slot. You can take an all terrain chip and make your on using 16 AWG wire using the manul on this site's home page.

just got through doing my 2004 txt pds e-z go.
downloaded the manual and followed the procedure.
1 turn the "run - tow" switch to tow.
2 remove the cover (controller enviromental cover).
3 plug in the jumper (chip).
4 replace the cover.
5 turn the "run - tow" switch back to run.
to find out what mode it changed to
toggle the forward/reverse switch from NEUTRAL TO REVERSE 5 times
a few seconds after the 5th toggle (beep) you will hear one of the following.
1 beep for all-terrain 13.5 mph
2 beeps for steep hill 13.5 mph
3 beeps for mild hill 14.5 mph
4 beeps for freedom 19 mph
after all this turn the "run - tow" switch back to tow then to run to escape the diagnostic mode ...then go drive and hang on.

It works great. With the "freedom" mode you loose some low end torque and gain the top end speed. The jumper I got had red wires (if that makes a difference)

How can it stay in the mode if there is nothing plug into it. The All Terrain plug is nothing but a plug with no wires. So if you don't have a chip plug in the controller it's in All Terrain mode.

I'm not sure if this reply is directed at my post, however if so I don't understand!
Obviously there is a default mode if there is no jumper present.
The diagnostic will still indicate the mode/ status "performance option" whatever you want co call it reguardsess ????
Are we just splitting hairs or symantics?
This procedure I posted was intended to share what I learned from the service manual.
Was there something I left out? Or didn't make clear?
