Can you connect to the car (flashtool or TunerPro without the OSE plugin enabled) with the factory memcal fitted? Or if you still have a memcal with the enhanced bin, can you connect to that?

I can connect to the Ecu with either the NVRAM or the old Memcal in there with the OSE turned off, in tunerpro, but the flashtool when it finally gets a heart beat returns ECU unknown
The screenshots are not mine
both jumpers are on VT and the R/W
i only get the memcal error when the NVRAM is fitted,
all the settings and plugin etc are all per the guide ose1.5
ive attached the Bin file that i am using
ive tried using my spare ecu still no love and also different cables ive had over the years,

Did you disconnect the battery when you swapped to the nvram

when i put in the original memcal (The1) i can connect to the PCM on the logger v2 mode, it lets me download the BIN and all the other things there
but it just wont connect to the NVRAM and even on logger v2 mode returns the unknown ECU. the cable is the one i got from envious customs so i could calibrate my fuel guage and set the airbag system etc, he made point that a cheaper cable may not stay connected and that could potentially brick your dash or other things you where flashing with it, so i doubt the cable is the problem nor none of my wiring or my current bin,, so no memcal error on my old memcal, same bin but slightly different timing tables, so shouldn't really make any difference to this problem, but as soon as the nvram goes in its memcal error 51
has to be a dodgy NVRAM?

Do you have a burner? If so try this guide to read the nvram back after burning and compair

Yes, the NVRAM does sound corrupted. You can get a minipro tl866cs programmer pretty cheap from ebay and fix it yourself. This is recommended as you can use it this time and in the future should you need it agian. Failing that biggvl should be able to fix it up, or I can. I'd also recommend keeping RW unset until you have everything working as it can prevent this from occurring while plugging the nvram and/or if the wrong file is accidentally uploaded to the car or the wrong xdf is used etc.

Be super careful lifting the nvram out. Its easy to bend the last pins and they are thin. Use a really small flathead, just in from the ends, and do each end a tiny bit, then the other end etc. It'll want to pop out at one end without taking the other with it.You'll need to hold the free end and then move the still attached end to get it right. Its not impossible you just need a bit of patience and to be ready for it. Also take note of the orientation when you put it back in. The dot goes down the end of the socket with the notch in it, or use your pic above as a reference.
