It's called a "CALPAK" it's an assembly of resistors, that sets up hardware settings, for cylinder count, and other things that need to be set that way.
No, there is no programming involved.
The man who says something is impossible, is usually interrupted by the man doing it.
i down loaded the hyway cruise for the 12147747 and i dont really know what to change. i need a usb adld cable that will work with tuner pro or tunercats if any one has one for sale, so i can data log on a 91 4.3 chevy pickup. i dont have a data logger and have proggramed 384 chips for this truck, it is close but not just right, some one put a 273 rear end in it an the spark, fuel, egr, are way off what they sould be. been guessing for 3 years at what to set things at.wanted to get a ostich from motes ,after reading what i posted maybe a different rear gear ratio should come first. still need a data log cable.
Other then turing things on and off, I would'nt know what to change in a bin file without data to tell what needs changed. You need a cable! Then start with a fresh/stock chip/bin.
It's not the gear ratio...

If you have a 4.3 and you're running a 2.73 rear end then you may want to go with a little lower gear ratio. I'm sure that the thing gets good mileage on the highway, but it's gotta run like a dog around town. I got my cable from Moates.net and it has worked flawlessly for a few years now. The price seems pretty reasonable to me at $80, but the main thing is that it works well with tunerpro and isn't difficult to set up. The only software required to use the cable is just the FTDI chipset driver that can be found anywhere including the moates website. Here's a link to the product page http://www.moates.net/aldu1-and-cabl...bl1-combo.html . I can identify with what you've had to deal with as my first tuning experience was with a nissan that had no data stream capability at all.

thanks for the info,proggramed a chip with hy way cruise today.just run it in the garage didnt drive it, run fast at idle,put my other chip in wouldnt go into close loop till i drove about 6 mile then restarted the truck. i guss the patch had already started to do its thing.the ecm always went closed loop after about a 1mile or less.waitting on a data logger before i do anymore testing.
How do you know open/closed loop without data logging?
You should have a good tune, backed up by data before using hyway lean cruise.
Lean cruise will not work while parked, warming up. It needs to meet qualifiers before entering open loop/HiWay Lean Cruise.
