    Had two customers over the weekend fail on a write due to low battery voltage. Both 2007 cars. When it fails sometimes you need to disconnect battery cable to reset the ECU and then try again. In both cases after they connected a charger it wrote fine. I think KLINE is more sensitive to it so if you're a 2007 be sure to connect a battery charger.

    Could someone e-mail me or link me to their own stock IJE0S BIN? I am curious to compare differences between ROMs.

    FYI total read took about 78 minutes.

    hmm my write bricked out for reasons unknown. I also saw that the initial write took 35 minutes and put the ecu in recovery mode.

    trying the write again and my wipers are going off very slowly. odd.

    I might have again forgot to put the JB4 on map 0 but now I cant even check because steering wheel controls are dead and JB4 interface won't connect.

    That happens when your battery dies. Wipers turn on and you won't be able to write until you remove the battery cable for a minute. When the DME has no firmware then the JB4 wheel controls won't work so be sure to switch to map 0 ahead of time. On my to-do list is to figure out how to program the JB4 to turn itself off when it sees a read or write command.

    A full DCAN write should take no more than 16 minutes. On KLINE around 11 minutes.

    People, I suggest taking your car for a spin and get the battery juiced a bit if you don't have a charger. The read drains the battery pretty well. Low battery will equate to slow, abnormal or poor operation.

    would low battery equate longer read/write times as well? Just curious.

    After the second flash which was successful (with the wipers slowly moving), after letting the car sit for a few minutes, I managed to get ignition on and the JB4 steering wheel controls activated, which confirmed I was on map 0.

    I am waiting for a friend to come so I can jump start this car and I'll drive it around to recharge.

    yep, jump started car. running shivs stacker map for starters with some changes I made on my end in terms of AFR target etc.

    why Shiv targets 10.8 AFR at WOT is beyond me.

    fwiw a cheap battery charger is $20 bucks and will work fine for this application. I think it should be recommended to use one while flashing. I needed it for my cobb flash. my batt is fine and starts right up. with a new or very healthy batt probably not an issue.

    Agreed. A battery charger is a tool many undervalue.

    Probably pick one up soon. Are you guys hooking it up using the points in the engine bay or at the battery itself. Does it matter?

    Positive terminal in the engine bay, they say the IBS needs to register the charge to stay accurate.

    Question, is 3 min, 33 seconds normal for a rewrite time? Still seems a bit slow. I'm only asking because it took 30-35 minutes for a full rewrite, and 78 minutes for read time which is slower than the estimates.

    yea, DCAN. I have an Acer Aspire which is one step larger than a netbook running Vista.

    My successful attempt was just trickle charged to full, and then I left the trickle on while I was using the software.

    Try using a different computer, with a full charge on your car battery and report back.

    Unfortunately, I don't have any other laptop to use. I guess I could use the BenQ S6 but I would strongly be against that idea considering it has about a 60 minute battery life. I guess for a rewrite it would be ok to test with though.

    BTW: I have done most reading/flashing Cobb and open source with procede NOT in map0 with no issues. Does JB work differently?

    The JB4 needs to be in map 0 to disable CAN activity on the bus. I presume the procede works the same way but I've never tried it myself. This is for DCAN cars. KLINE (2007 models) is another story all together. For those I don't think it matters.

    regarding my abnormally slow read/write times, I had a super old version of BT software on my laptop circa 2009. would it help if I uninstalled everything including bb software and BT software and start from scratch?

    or is there a baud rate setting or something that may help?

    I also have CIC iDrive.. not sure if that interferes with the read/write process but I doubt it.

    There is a ton of timing stuff coded into the software that could affect your results. Trying a new computer would be my first trouble shooting advice.
