Bamachips Automatic tune files and gear changes..
Hey guys,
As I'm sure you know if you have my automatic tunes my shifting is entirely different then that of the stock tunes or even the SCT or Diablosport base files. The shift points are set mainly by MPH instead of RPM, except at WOT.
Now when you update your gear ratio this changes everything for the shifting as the MPH points remain the same but the engine RPM at that MPH point is different. So now your transmission shifts faster, depending on the new gear ratio how much faster.
When you update your tunes using the user options on both SCT and Diablosport products it is simply changing the Speedometer settings and correcting this part of the equation. This works fine on the stock tune or even most SCT base files but not on my tunes.
For example say you went to 3.73 gears from the stock 3.31's, at 55mph you used to be doing around 2300 rpm's but now with 3.73's your doing nearly 2600 rpm's. So now you can see why changes need to be made. Also with the converter lock up rates, there again using my tunes.
Feel free to check with your own tuner for required changes using someone elses tunes.
So, if you have gearing changes and you have my tunes that I've not adjusted for and you are feeling faster shift points or the that the transmission isn't shifting properly then just let me know and I'll take care of it for you. This is all covered under my free tune updates for minor bolt ons for the ownership period of your car.
Thanks, Doug.

Quality customer service from a quality guy! Thank you Doug for resending my 93 race tune to my gmail account. My car leaves the shop on Saturday, and I can't wait to try it out.
There is a healthy number of Mustangs here in Kuwait that are aching for a good tuning. I'm doing my part and spreading the word about your quality work. Hopefully, you should be getting more orders from around here. Cheers.

Does this no longer apply?
I have one of your tunes for a 2006 auto, but when I emailed c&l about getting a new tune for 4.10 gears they said I only need to change the ratio in the tuner and a new tune is not needed.
