Throttle controller - Warranty

[5teve]

HI Guys

Just bought an Ultimate9 EVC controller - Didnt realise there was an EVCX too... so i have the non removeable screen (well I assume you cant remove it) and no bluetooth...

So a few questions -

1. Is the EVCX really worth the upgrade if i dont want to mess around all the time?
2. Warranty wise - how do throttle controllers go? If i left the screen in place - will i be pinged for it (obviously if i have a log full of throttle errors then that would be valid)
3. Did I screw up not getting the evcx?

Can you disconnect the EVC non-removable screen, or does that affect function?

I got the EVCX for the duplicity of both screen and App. I have a black magnet adhered to the dash and a steel disc on the back of the removable controller.

In my experience. Once you find a setting that suits you, there is very little further interaction with the throttle commander. It just helps sort out whatever you are looking for. In my case, a reduced lag on the diesel engine when pulling away from a very slow pace.

Did I screw up not getting the evcx?

I just installed the Ultimate9 evcx yesterday and tested it around the neighborhood. I’ll be out most of today driving the Grenny, so I should be able to get a better feel for its effects.

I don’t anticipate that I will be changing settings on the fly . . . that seems like a recipe for distracted driving. I mounted my USB controller low on the dash just below the bottom edge so I’d need to get out of the vehicle to fool with it. For finding a setting I like, I’ll hand my phone with the iOS app to my wife and have her change the settings while I drive. That seems like the biggest advantage of the Bluetooth app. As far as warranty concerns, the controller has a pass-thru mode where it doesn’t do anything - that’s what I’d set when the Grenny goes to the dealer. I just received my Globe Guard OBD II code reader a few days ago, so I’ll check for throttle-related codes tonight and report back.

A side note - for those of you complaining about how hard it is to remove the connector from the throttle pedal - it’s not you. The connector is poorly designed and implemented. I say this from the vantage point of interacting with hundreds of different connector styles in both a professional and hobbyist environment.

It is easy to do, once you know the tricks described here (for me, it went from a nightmare to a walk in the park):

OK I was confused how to find the bolt and install the throttle controller, so I read the thread and have written up a Dummy’s Guide. Thanks to about 6 different posters.

Ultimate 9 Throttle Controller (fitting to a RHD car)
1. Open the driver’s door.
2. Take the FOB remote inside your house away from the car.
3. Wait 10 minutes for the car to go to sleep, to minimize any fault codes.
4. Remove the bolt at the base of the accelerator assembly. The bolt is located under a small black plastic cover (see white arrow below).

5. Remove the black plastic cover with a pick...

Thanks to your prior post - I did exactly that. Then I was able to examine the mating halves of the connector and determine that when the locking tabs are depressed to their fullest extent, one of them would not clear the protrusion on the mating connector body. The only way my connector would come apart was to use a small screwdriver and pry that one connector tab up. Additionally, the pins inside don’t easily mate with the other half because the two connector bodies don’t self-align until after the pins seat together. All around, that’s some shitty design right there. Like I said, I’ve dealt with literally hundreds of different connectors and dozens of manufacturers, and these are some of the worst I’ve ever encountered. EVER.

If your connector works better than mine, you are fortunate. That could point to worn out molds used to make mine, poor accommodation for shrinkage during manufacture, or a change in the properties of the material used.

I guess I should go get a lotto ticket then as mine popped out pretty easily even with my bunch of banana fingers.... I'll take it as a win then...

Still wondering if I should swap this now for the evcx.. just for the removable nature of it

@5teve - I didn’t get any test drives in today. I went down to the garage and smelled a dead animal - ended up having to remove the rear bumper on my VW to conduct an extraordinary rendition of a mouse that hid in a body cavity and made the inconsiderate choice of dying there.

I did, however, get the OBD II reader working and I didn’t find any error codes that looked like they were related to the evcX throttle controller. I’ll check again tomorrow when we go on the drive we were supposed to do today. Dang mice!
