My understanding from Ford engineers is all they can see with a stock tune is how many ignition cycles have occurred. So if you bring it in with 25,000 miles and only 50 key cycles they know it was reflashed. Of course they can see a non stock tune.
FWIW I remember a similar issue on first Gen Fusions that had to do with the engine not stopping in the correct position which caused it to not restart intermittently. I think it was maybe the crankshaft or camshaft position sensor but I really don’t remember.
I don’t think it’s covered under the emissions warranty. You could take it in with 3/4 tank and let the dealer fill it up and test it, but I would probably just replace the purge valve first since that’s the root cause then if it continues to do it replace the Evap canister.
Well we know the 6F55 was used with the 3.0Leb and with the 3.5leb in the Explorer/Taurus/MKS and some of those have been tuned so I think there is a some headroom there. But I would be wary of removing all the factory torque limitations.
Doesnt it seem silly to go to all that trouble and expense and risk blowing up expensive parts just to get a little more power on a vehicle that’s driven on the street?
My point was just that there is a good reason they’re limiting torque in lower gears. You’d likely need to beef up the tranny, ptu, driveshaft and diff to handle a lot more power.
Hey I’m in Canton! How could you have missed the chip shortage affecting car production? It’s affecting everyone but Ford is even worse because they also had a fire shut down their supplier in Japan. Jeep dealer in Jasper had 13 vehicles total. Chevy isn’t much better. Most everyone has dropped rebates and dealers are asking MSRP. Ford even raised prices across the board. It is starting to get better but it will be several months to a year or more before production is back to normal.
