hello to all I have a recurring problem for some time, I have a fault 16985 internal error checksum memory, I specify I am in stage 1 e85, I have tried several manipulations other ecu same, other flash cord Same mpps, kess, in the rosstech list it mentions low voltage, I have a new alternator but my battery which is 2 years old at most gives strange signs of voltage drop at start-up 8V and this is often where the fault appears, forcing it to be reflashed 'ecu I don't know where to look anymore I have 12.5V when stationary and 14V with the engine running, small indications the engine in some cases has trouble launching it

attached is the link of the video where we see the instrument weaken at stort hottom: 100ah or 900a of memory 公 | 2/2 | V

some custom code for launch control involved?

what do you mean by custom code ? cordially

good thing you posted the output of me7sum

Return to stock, or find a competent tuner.

hello it's possible not as efficient as the new automatic gearboxes and not great for that mechanical nevertheless doable

I will also try but the concern is to determine if it is indeed a software problem so map or checksum or electric battery, ground ect hence my question cordially
