What I think we have a right to expect is . . . . that if the customer us using any EVSE which is 100% compliant with the J1772 standard, then the car should recognize that and function as advertised

Giving us a built-in 'hiccup' in the cars software so it only works properly with this or that brand of EVSE just isn't acceptable - I know everyone is tired of hearing my anology, but this is exactly the same as if an ICE vehicle manufacturer built a car which would only operate on Chevron gas . . . . because they had some sweetheart deal with Chevron

Thats a separate issue, the OP complained about Mitsubishi technicians poo-poo'ing his modified EVSE. That's a given, I wouldn't have said anything to them about it because the technicians are going to suspect that right away.

This problem is very different from gasoline, its a software/hardware compatability problem. Petrolium companies can put all kinds of twists on the gasoline standard by putting additives into the fuel, but your car will still run. Software is very different, depending on how its coded - the software may be expecting only one value not a range of values, its all in the keystroke (x = 1 or x >= 1 && x <=5).

From reading all of the documents on the Open EVSE site, I know I came across something that said the J1772 is a standard but not all companies follow it to the letter. With all the EVSEs we have on this forum and with all the different results we are getting, I can see this to be true. Obviously some did follow the J1772 standards and others put their own twist on it.

Being in the software industry myself, I know the nightmare this is for Mitsubishi. Building software is very difficult because you never know what the end user is going to do with it. We have to code for every possible possibility and we still miss a lot and get complaints and support tickets. I'm glad I only code internal projects where I can be guaranteed what web browser is being used. There are HTML standards and everyone is SUPPOSED to follow it, but everyone knows that each browser has their own twists on the standard.

We are basically driving a computer and its going to have its quirks and bugs when used with various adapters. Liken this to the early days of PCs when we wanted to add a video card or some other peripheral. What a headache! Very lucky if it even worked with your brand of computer and setting all the dip switches a hundred different ways and staying up all freaking night to realize the video card wasn't even compatible even though the box said it was! I remember those days very clearly, especially since I was a field service technician back then.

I know this sounds like fanboy crap but I just don't see where Mitsubishi is at fault here. The remote works with the supplied EVSE. The remote is not a standard piece of equipment on an Electric Vehicle - its a nicety and a mileage saver. Some cars overseas don't even come with the remote. If you aren't getting the results you desire, then I'd suggest not modifying the supplied EVSE or buying one of the EVSEs where the remote does work. Also, all the cars are charging from the various EVSE, again Mitsubishi delivered as advertised. I don't recall reading anywhere that the remote is guaranteed to work with all EVSEs. That is asking for a lot of extra expense that would raise the price of the car.

MLucas, it was pure speculation (and hope) that the Clipper Creek EVSE issue was Remote-related.
derminghsieh provided the text of the Mitsu letter and it sounds as though there's an end-of-charge problem.
In any case, I'm glad that's being addressed and we'll see if any fixes carry-over to the Remote issue.

Thanks, JoeS. I too hope it carries over and fixes the remote issue with the EVSEs that are having the problem. Its a nifty gadget that I've become accustomed to having.

I think our problem is that Mitsu has 'put their own twist on it'

Obviously, I don't know 1/10th of what you do about programming, but there is still a standard and the car should be programmed to operate correctly with any EVSE following that standard

What Chris at Open EVSE was talking about with reference to not all companies following the standard to the letter is the fact that the standard calls for the EVSE having GFCI protection, stuck relay protection and open/shorted diode protection, as well as sensing the need for battery ventilation - Our OEM EVSE built by Panasonic does none of that, but some other brands do, the Open EVSE being among them

Obviously, Mitsu can program the car to where it accepts a very loose interpretation of the J1772 standard . . . . otherwise the OEM EVSE would not work. Surely, it shouldn't be a big issue for them to program the car to accept a strict(er) interpretation of the standard - In other words, if you have an EVSE which better adheres to the standard than the one that came with the car, it ought to work and all the car's functions should work as advertised. I suspect this is what's coming with the 'Clipper Creek' software update . . . . at least I hope that's what they're doing

I got the Clipper Creek letter from Mitsu today and it sounds like they recognize that the problem is with the car and not with this particular EVSE. Hopefuly, reprogramming the car to correct this 'incompatibility' will resolve the EVSE/Remote Control issues many here have been experiencing

As a daily user of the Remote, and someone who has a GE Wattstation that requires me to do the "On/Off Dance" I was thrilled to receive the same letter today.

Even though the letter names Clipper Creek specifically, this issue is not specific to them only. I'm sure my Wattstation will finally be working just like my Mitsubishi supplied EVSA after this update. To bad I have to wait for January.

I'll report back once I can verify this does indeed solve the issue.

Thanks everyone for their contributions.

I thought to add mine. I have EVSEUpgraded original Panasonic unit that is used mostly at L1. I do use the remote from time to time and it works normally without a glitch (at L1). One thing to mention is that I did not realize until recently that the precool/preheat function will work only when all the doors are closed. Make sure you are not making the same mistake. You can open the door once the process initiates, though.

It's January. Has anyone had this update performed yet?

EDIT: Nevermind, called my dealer and the firmware hasn't arrived yet. Said to try back in a couple weeks. I think i'm going to wait until Mitsubishi sends me another letter saying the firmware is actually ready, or check again in February.
