Why do people continue to fall for this junk even after there are multiple threads saying it is junk.
Because there's a sucker born every minute. For every person educated on a matter there's at least 10 that isn't.Why do people continue to fall for this junk even after there are multiple threads saying it is junk.
The piggyback unit is much different that a "chip". The piggy is a programmable box that changes the fuel mappings for a car. I ran one on my SX4 when I had an NA tune and then a different one to run my turbo set up. Road///Race even has a whole page about tuning using the software. They make a noticeable difference in power and MPG's if the stock AF is really bad. The SX4 ran really rich and the piggy fixed that for a lot of guys, it is a well received product on the SX4 forum.Sounds to me like this chip does nothing more than trick the computer into thinking the intake air temp is lower than it actually is. It will add a bit of timing. Gains are minimal. Waste of money in my opinion. Probably all that's inside is a 5 cent resistor. Also there's a good chance the computer will learn around it. At least on Fords, the computer looks at the intake air temp and the engine coolant temp on startup after the engine has been off for a long time. If the two are not equal, it assumes the sensor is off, and adapts.
I like the piggy back option for a couple good reasons. If you get a piggy back and you have a local shop or friend who can tune then you can make constant changes as you work on the car. Get a header, new tune; different intake, new tune; light weight pulley, new tune. Also if there are issues with the programing you just take the piggy off and you are back to stock.which do you guys think is better, a piggyback or a reflash?
Hmmm... I'd be interested to know more about this. Are you actually cutting the fuel injector and coil wires and the "piggy" runs them? Or what?The piggyback unit is much different that a "chip".

You splice into the wire harness leading to the ECU. There is enough wire to have it mount out of sight so most of the time people don't know you have it.Hmmm... I'd be interested to know more about this. Are you actually cutting the fuel injector and coil wires and the "piggy" runs them? Or what?
I have a Pectel T2 on my Focus. You unplug the engine harness, and plug in the T2 harness. It has full control from there, no messing around. Laptop programmable, yadda yadda.
Of course, that was $2100 back in 2001.![]()
I am not sure how the Forte one works, but mine I had to sever one wire and vampire in on 2 or 3 more.So is the system adding a parallel ground to the injectors, or are you actually severing the wires to the factory ECU?
