Not to hi-jack, but hopefully revive...has anyone just bought a new ECM and had it tuned? That’s my line of thought at this point. It seems that the days of handheld tuners with downloaded tunes are going the way of the Buffalo. It looks to me that a oem Ford ECM will run about $650 for a 2020, and from what I can tell should be plug and play for the truck- no dealership needed to flash/format. If that’s the case, I’ll leave my stock ECM exactly that, and just send in the new one for tuning. If I’m not mistaken, any flash done at the dealership will wipe the tunes, effectively pissing away the time and money spent wringing out the extra power. If the truck does have a problem, I’ll plug my stock brain back in, keeping my expensive a$$ tunes safe and sound from the evil dealer flash. Is this logical thinking, or am I missing something? I do realize that that is an extra expense with the spare ecm, but it’s cheaper than what most decent handheld tuners would cost for a 15’-19’. Any suggestions on where to get the flash? I’m seeing most offering 100hp gains with emissions intact, which I do intend to keep, but the more the merrier...until it breaks. I’m ok with a respectable, but safe, level of improvement. I have seen some dyno figures posted that sound very suspect. The truck is rated at 475/1050, so to see stock numbers at 471/1068 makes me call bs on the tuned gains. TFL put a stock 19’ and 20’ on a dyno, and while impressive, the 2020 didn’t put down numbers like that. Perhaps the dyno was just badly out of calibration. Does anyone know of any real-world un-inflated tunes numbers? Thanks to all who reply in advance.
