996tt ECU “reflash”
Question for anyone out there with an ECU tune + corresponding upgrades:
I bought a modified car a few years ago and for the most part it’s been great, but recently it has been slow to crank when starting. Several diagnostic tests from reputable speed shops found nothing mechanically wrong (replaced starter, no battery or cable issues) but noted issues with starter encoding within the ECU, often resulting in a battery warning light - the car does start but you have to hold ignition on for 5-7 seconds
Based on notes from seller it has an EVOMS (evolution motor sports) ECU, turbo kit and intake kit
I am not having much luck in getting in touch with EVOMS for trouble shooting the issue, so to the question, what might the risks be to reflashing the ECU with a different tuner mapping or better to do a stock reflash (assuming at a Porsche dealer?)
Understanding I’ll lose good deal of power with stock ECU but still more than bone stock given the turbos and intake upgrades.
A bit of a unique one here but figured it was worth asking!
