OK... will make an app't for the 535 although i have no issue with the 530. Is there any issue with 535 over-writing the CIU files as 530? My lay attempt at describing.

My understanding is that it only writes to the BECM and nothing to do with CIU or any other module. 530 to 535 ought to be the most painless upgrade.

Note and/or question: I have been upgraded to 535 and now when I plug in to my home charger (which is set to delay charging until 11 PM), some part of the cooling system fires up for a while, based on the sounds (pump running and water trickling).

This is new; the old 520 software just waited for the 11 PM charge-allowed time (waking up every once in a while to see if charging current was available yet).

It does not seem to be a problem, but I thought I would note it, and see if it's expected.

I am not sure if this is a 530 problem. I have 520 on my car and also use a delayed charging schedule to take advantage of EV-specific rates offered by my utility. Occasionally, usually after a short Stealth mode drive, the cooling fans come on after I plug the car in but before the power is turned on. It does not seem to affect charging, however. The car charges overnight and is fully charged by morning.

It's possible that 520 did this and I never noticed. I don't think it did, though. Perhaps 530 / 535 does it more often?

I have experienced cases where, after returning home, a louder fan ran until I plugged the car in (which I thought was odd: if it needs cooling before charging, it certainly still needs cooling while waiting for, or receiving, charging current!). That was with 510 and/or 520, though. Note that my shutdown process includes turning off the air conditioning before pressing the main power button.

In any case, I have not seen any new problems, just making a note of what seems to be a small change.

The car has two coolant pumps behind the rear bumper that cool the OBCM while the car is charging and running. Its normal for the pumps to run while charging the water your hearing is the coolant circulating . I would check the coolant level in the coolant tank on the right front fender it might be low on coolant. When they are low you can hear the coolant.
The fan behind the front bumper on the passenger side runs if the cooling system for the OBCM and or the invertors is running hot. If that fan runs all the time the car is charging the OBCM might have a issue or again the system might be low on coolant

So, now that I have 535, I'm on my 3rd straight "run it down to 0 Stealth" charge tonight. Should I expect that it will go into Cell Balance mode? I am trying to force it. Is that still the method? I expected it last time (2nd time in a row run down to 0), but it stopped in 5 hours.

FiskerPhilly did my 535 update today, as did several of us met in Fall Church Virginia - So far so good. Parked my car and in seconds it went to sleep -- so far so good.

Thank you Joe!

Are you saying the shutdown timer is even faster in 5.35 than the 45 seconds (or so) introduced by 5.20? Or just that the car shutdown normally tonight after the 5.35 update?

Well, to me the car went to sleep quicker than normal. I think I had the 5.20 update done and with this latest 5.35 i noticed it went to sleep much faster.

Also. I only lost my pre set seat, everything else stayed the same after the update. Joe is the man!

Just picked mine up after the 535 instal. Drove it from San Francisco to San Jose and all was good except for the tire warning indicator light coming on (checked tires and they are fine). No diag to worry about. I'll do a hard reset and hopefully that will be the end of it. Still need to fully charge it. My car also passed the inspection so I can obtain the warranty.

Do you have to run it to zero? I am not aware and I haven't scheduled the update yet. I was kind of waiting to see what everyone thinks so far. I've only had the car just over a week, so I am trying to get a feel for it. The steering wheel wheel advance forward radio station button is touchy and seems to not work more that work, so I have to scroll songs backwards.

No, no. @jomak. The way that the old 510/520 software triggers the car's computer to initiate Cell Balancing following the normal charge cycle -- was to run the car down to 0. Fully charge. Then run it down to 0 again. This is not something you have to do to get the new software or anything.

As I understand it, once the car is fully charged, if you leave it plugged into the charger, it will automatically go into cell balance mode and adjusts the cells as long as it remains plugged in.

Drawing the HV battery down to 0 miles (15% SOC) is just to exercise the cells to expose any voltage differences.
