i have a Nerve essential ECU it is a removable eprom, opened up the case and which had stickers all over it, opened it up and there was a Square eprom i think they call it,

with essential sticker on it,

obviously this is remaped, i want to check the tune, obviously ill have to buy a eprom programmer/reader that takes this square type of eprom do they call this a DIP socket?

what do i use to read and edit this rom as in software?

your help would be much apreciated.

rom is downloadeable via consult cable with the ecu in your car. no need to take the chip out.

please provide me with a link or eg. of this consult cable, ill pretty much buy exactly what is needed, what about software what can be used to view and tune?

The r33 chip contains the map inside it. Essentially, you need to buy a h8 processor. r33 chips are one right only.

therefore, you have to buy a eprom writer which can do h8, and you need to buy a h8 - they're about $70 each

Eseentially, tuning is not really a diy thing

Nissandatascan has a rom dump feature so i guess so.

Yes you need a consult cable - i bought the plms one and it works fine.

u can use calumsult or tecu (both free) to dump rom. best software for rom dumping (in order) is calumsult(using old exe), tecu, and then datascan. calumsult works 100% all the time, tecu works probably 95% of time with serial consult cables (less often with usb/serial converters), and i can never complete a full dump with datascan.

however aftermarket ecu's might have protection against downloading rom with consult (ie they could have found the code in ecu that handles rom downloads and disabled it)

      I believe Unimog is the only vehicle that has it (from the manufacturer). I haven't seen aftermarket permanently connected kits, but I haven't looked either.

      Ha ha ha, can't overthink when exhausted... Oh how I wish I had that power! I can be absolutely dead set shot, and my brain will still go "we need a good 3 or 4 hours to just think about everything and anything before you may sleep... My biggest thing is making sure I give myself enough sleep. I don't operate on even 7 hours of sleep! I attempt to give my body 9.5hours sleep a night to be able to function. I don't sleep the whole 9.5, but I need to make sure I offer a big window. I also take a single supplement, which is to help with long term health, and fighting inflammation, and I notice it helps massively. Especially me sleeping, and just less "achey" in the body. Have also kicked sugar, and gluten. A majority of people with ADHD don't go well with gluten. It causes a really interesting natural opioid overdose in the brain, which causes bodily issues and sensory issues.

      Yeah that's what I meant, permanently connected not manual

      Yep. But typically that's just run a hose down to the tyre while stationary.   Oh and the Unimog will automatically air up and air down tyres from the onboard computer for you too.

      There was a good video somewhere, maybe Kurzgesagt that linked physical activity to ADHD/Anxiety/Insomnia etc. Basically the body WILL spend energy doing something if you don't spend it doing anything physical. It isn't fun, but I personally have noticed I've never been overthinky, or unable to sleep if I'm physically exhausted from doing a lot. The musings around it seem to indicate that this is one of the reasons/mechanism that physical activity improves mental health/wellbeing etc, by more or less not using that 'extra' energy to overthink, be anxious, inflammation, etc. There's also the fact that every obnoxious exerciser ever says it's great and helps which is extremely annoying. Like people who say the same thing about travel being the best thing ever. I mean, they clearly are, but blah. I started doing a LITTLE myself (think 3x15min per week) and honestly did notice the benefits, aiming at life quality when older. Which is sooner than you think. Getting something into your routine that you can actually make a routine has helped me at least. This post brought to you by procrastination between sets.
