i just got the Mflash done to my car and the 3rd time i get in my car after the mflash it took 6 seconds to actually turn the car on.. wtf I mean wasnt the Mflash supposed to take care of hard starts like this and wasnt that its purpose?
I also did the oil gauge test and i do have the mflash. The gas mileage has improved but i am still very disappointed about the hard start.

mazda is letting me down one way after another.

 

Have they changed your plugs? And what brand of gas are you using?

 

well that would depend on why your car was hard to start. perhaps your "hard to start" situation had nothing to do with what m-flash was fixing. if it was mechanical and not computer related

 

I have to say that since I've had the "M" flash my car has started up a lot easier. I was having hard starts before. Then again it is warmer now that it's summer. We'll see how it does in the fall.

 

I don't understand why you think Mazda is letting you down, were you suffering from hard starting before, and the problem has not changed?

I can vouch for the new flash. It definitely makes a difference. I have tested two vehicles before and after the flash and they both started easier. Your fuel economy may be better too.

If you have something wrong with your car though the leaner mixture the 'M' flash runs will make the problem worse. Take it back to your dealer if you have more problems, but give the flash a chance first...
