I don’t know if this is a universal problem or not, but it’s really killing my momentum with tuning my ‘17 SS. The first time I used HP Tuners to flash my ECU/“write vehicle”, I just about had a heart attack because it wouldn’t start. I thought I had done irreparable damage to my car until I read a post over on HP Tuners where someone just had to wait 10-15 minutes or disconnect/reconnect the battery to get the car to start again. Well, now every single time I write an updated tune to my ECU, I have to wait at least 10 minutes before the car will start. Any earlier, and it will just sputter and die after I press start. Is this a known/common issue with HP Tuners? I’m getting kinda frustrated with this whole process and don’t wanna twiddle my thumbs for 10 minutes every time I write a new calibration to my ECU. Any advice or known fixes? Thanks!
