I installed my new Superchip Friday of last week. Everything went well, and all has gone fine until today. The truck still runs fine, but it almost seems as though it has gone back to the stock smooth shifting. I checked the connection and it is still plugged in firmly and is taped up. Even at 3/4 throttle it shifts really smooth. Has anybody had this problem before, the chip has seemed to work well up to my last trip. I have 270 miles on it right now.

Thanks.

 

Well, on the brighter side, my muffler came today.

I'll drive the truck a little tonight to see if it was just a phase the truck was going through in the learning process or something.

 

Hi 94,

The program in the Superchip cannot, and hence does not ever change. The only way that can happen is if you send it in to us and we change it.

However, you mentioned an important point, and that is the effect of the ECU going thru it's relearn cycle and adaptive strategy having it's effects, you're absolutely right. And if you drive the vehicle non-aggressively more often than not, like if you do a fair amount of highway driving or crusing, for example, adaptive strategy can indeed soften up the shifts a bit, as it's a matter of the manner in which the vehicle is driven most of the time. The frequency with which you give it heavy throttle, in other words. The more you do that, the more it tends to shift harder, though this isn't a open-ended ior unlimited proposition, the total swing isn't that great, but it can be enough to be noticeable.

Another point is that sometimes when you install the Superchip, you will actually get firmer than normal shifting at first, before the transmission adapts to it's new program, and then as it does adapt, you get the end result, which may be softer at less than very heavy throttle.

The shifts from the Superchip are firmed only in response to the amount of throttle opening. The shifts are designed to reduce slippage and to improve performance without causing any detrimental affect on the transmission. It is only at full-throttle or at extremely heavy throttle that the shifts start to get "snappy," though at any throttle position the delays & retards are pulled and it executes shifts quicker to reduce slippage & extend the service life of the friction materials. Even at full-throttle it's not going to be any kind of neck snapper of course. It's not good to make a transmission shift that hard **via electronic altering of line pressure alone,** so we don't do that.

There is never any issue in the Superchip's actual "consistency" simply because it's program, the actual contents of each line of code, cannot just change on it's own, it's physically impossible. The Superchip is always going to do exactly what it does, the only variables here are your vehicle and it's condition, the effects of adaptive strategy along with the fuel quality, which affects power which can affect perceived shift firmness.

This is just some quick FYI stuff, & I hope that helps your understanding of this a bit. You might want to give us a call on this and we can go over this in detail to see exactly what you're experiencing just to make sure it's normal and proper. Please feel free to call if you'd like to go over that!
