Td and hy jacker

Having a hard time finding the differences in the two. Anyone know of a good tech tread of the two or tell me what you know about the two. Do they both always change boost with elevation or they set.
 
TD is a complete ECU reflash. Hi Jacker and Ez Jacker are plug and play. TD will violate warranty. Jackers can be removed and sled put back to stock. Hi Jacker has tuning features a TD reflash does not.
 
I called and spoke to some people about it. The way I understand is that Cat designed the engine to have plenty of spare boost. It compensates for altitude by adding more boost. At sea level, it is using very little to maintain 177 hp. At 10,000ft, it is using quite a bit, but not all.

Both the EZ Jacker and TD/Speedwerx reflash do the same thing, but in a different way. Both increase the boost to maintain a hp. Problem is, the turbo is not that big and eventually you will run out of turbo no matter whether you have the EZ Jacker or Reflash, so there is a limit to how much hp can be gained from either without a bigger turbo. Most I have read about or talked too say 220-240 is about all you are going to get out of the stock turbo and you may have to run some race gas to get it so you do not have detonation. A meth kit and race gas may get you a little more.

The EZ Jacker and Hi Jacker basically intercepts the signals from the ECU and modifies them. The ECU plugs into the EZ/Hi jacker and then the EZ/Hi Jacker takes the stock signal and modifies it. Only difference between the Ez Jacker and Hi jacker is the Hi Jacker has adjustable power setting and tuning capability. The Ez Jacker is simply plug and play.

The ECU Reflash modifies the stock settings in the ECU so the signals coming out of the ECU are already modified. The ECU reflashes have different settings so you can adjust power. The Hi Jacker does too. EZ jacker does not.

I decided to go with the EZ jacker for simplicity. One hp setting so I don't have to adjust clutch wieghts and settings for increases and decreases in power. I also wanted to be able to put it back to stock if I needed to.

Most systems require an aftermarket can to get the most out of them. Still, for the money, it seems to be about the most cost effective way to pick up 30-40 hp I have ever seen in a sled. You do have to take your ECU, remove it and send it to a TD dealer or Speedwerx for the reflash. You can also buy one already done off the shelf and send your back in for credit. The Jackers, you simply buy and install. Takes about 30-45 min.

Well, that is the jist of it as I understand it. I am sure some others have a better understanding, but that seems to be pretty much it. Good luck on whatever you decide on.

I would have to say that the Reflash has its benefits as well as the ezjacker and the hyjacker.

TD/Speedwerx/JD Reflashes: With the reflash they have the ability to control rpm, timing, fuel and boost as well as other engine systems, Warning levels can be changed, etc.

EZ: Plug and plug Chip. One setting, very pump gas safe. Has a rapid response button that allows the turbo to come to full boost rather than the ecu limiting it at lower rpms to make it more "trail Friendly". Alot I think will end up with this jumpered or switched rather than using the button. With the button pushed arm wrenching low rpm torque will result which I feel will be helpful in the trees.

Hyjacker: I would have to say I am not to familiar with the hyjacker. It def has adjustable settings from stock to full race fuel. Also has custom adjustable menu for adding bigger turbos and creating custom fuel mapping.

I think all of these are great and by years end all of them should have a fair about of mountain testing on them. They all have been proven for low elevation trail riding previously. But without the demand in the mountains in the last few years in the Twin Spar chassis there has not been much mountain testing.

One thing to remember is that Boondocker along with d&d racing developed the hyjacker and ezjacker. Boondocker tests in the mountains exclusively. So in my opinion right now the ezjacker or hyjacker at the definate choice if you have to have it now. By next season I would guess that speedwerx will have a mountian specific mapping as well as TD.

I think next fall should have some very cool stuff for the 1100t. Upgrade turbos, mapping, etc. But with the late production most companies will not release these upgrades till late winter or summer.
