EV Mode From Coastal: Any Experience Out There?

I also noticed that it won't turn off using the stalk. Other than that, no problems, specifically no problems with the cruise control, which is unaffected. Some of the discussions pertain to his proto version, not the one he's selling today.

That's a shame... so how do YOU turn it off? Just accelerate quickly?

And by the way... how long did it take from the time you ordered it to the time that it was delivered to you?

Oh boy, I am still shaking!

I received my Coastal EV Kit yesterday and installed it with minor problem getting the pin into slot 27 far enough. After about 35 minutes, success! Test drove it last night and on my way to work this morning, for lunch, and back home without any problems.

Then I had a meeting tonight so I headed out and … no beep beep. I could not get the EV mode going. When I got home, I disassembled the dash to expertly remove the plug and jam a tiny optical screwdriver down slot 27 again. Plugged it in and … Nope. Three more trys.. nothing. I noticed that the black and white wire in hole 1 tap connector did not seem correct, so I made sure that the wire was firmly pushed into the tap connector. Reassemble, nothing, not even the three beeps. ???

Looking into the dashboard, I noticed that the black and white wire had split in two! Yippee skippee! I had this thing working last night and now I do not think the car is going to work at all.  After calming down and grabbing some extra wire, I soldered the two ends of the black and white wire to my new piece of wire with the tap connector already perfectly in place. I had some wire connectors lying around so I placed it over my soldered ends and clamped them so the bare wires were covered. I walked around to the driver’s side, sat down, put the fob in, pressed power, and pulled the CC switch towards me and …. Beep! beep! and the “Energy” view displayed on the screen!

I am probably the only person to have problems with the tap connectors and not the 27 pin (Ok, I had a little problem with the pin). I am hoping that I got it right this time. Has anyone else had problems after the EV switch was working for a while and then stopped working?

Got mine in the mail today, had it installed about 35 minutes later.

It works perfectly. It was a rush to cruise around the neighborhood in EV mode this evening! Pretty good acceleration too -- much more than I expected from the electric motor. You can definitely tell where the torque of the car comes from!

I also noticed I couldn't deactivate it via the stalk, but a quick punch of the accelerator pedal brings it right out. The installation is pretty simple if you are mechanical, just take your time with that pin. It's a tight fit in there and you wouldn't want to pull anything loose.

All in all, thumbs up to Coastal!

got mine two days ago and it was a breeze to install. i can disable it via the stalk no problem. just need to hold it for a couple seconds. instructions are great, step by step, read the whole thing through once. he gives a bunch of heads up so you wont have a problem

and the pin needs to be pretty far in. i used a pin punch. (has a tip on it just like those steel tipped dart...actually one of those will help you a lot)

That's good news. And, just to be clear, the cruise control works normally with the device installed? In other words, no problem canceling cruise control with the device installed?

Another question... can you enter into EV-mode while rolling, or do you need to come to a complete stop first?

Thanks in advance for the info... I sent an email to Coastal Tech the same day I posted this thread asking for the same info, and I have yet to hear back from them. They don't seem to excited about selling their products.

Well hopefully I didn't speak too soon.

Am I correct in assuming that if I get the 3 beeps when trying to engage EV that everything is wired up properly and the car is choosing not to let me engage it? Or is it possible to get the 3 beeps with an installation issue (pin not making contact, etc)?

Last night after the install, it worked perfectly. I used it again this morning without any issues on the way to work. After sitting in the parking lot all morning however, I could not get it to engage during my lunch hour. My requests for EV mode were always met with 3 beeps. I tried it probably 50 times before I finally gave up on EV mode for that trip.

Is this the car's computer preventing EV mode? Or do you think I have an installation issue? My biggest question -- is it possible to get the 3 beeps if a wire came loose? Hopefully this is temperature related, as it is pretty warm outside today. Not terribly hot, but around 85 F or so.

[bsumpter]

Disregard the above post. I suppose it is temperature related.

After parking my car in the shade for an hour or so, EV mode engaged just fine with a single beep! So now I know it's not an installation problem -- it's apparently just the Prius computer protecting the HV battery.

Good information to know.

you couldnt engage if your car is in the warmup cycle whenfirst starting. to prevent this from happening. hold the CC stalk whne starting and it will start directly into EV mode
