No mate, unichip is in a class of its own.
Its hard to explain all the things it can do without rambling on and making the post massive, but suffice to say it has at least 10x more features than any other chip on the market.
Ill try and give a short and sweet list.
Tunit - DP - Steinbauer - Rapid - DTUK + most of the others
1) Increases fuel
Unichip -
1) Increase or decrease fuel
2) Alter injection timing
3) Alter boost electronically even on ZD30's that had no electronic control standard.
4) Safety backdown water temp
5) Safety backdown air temp
6) Safety backdown exhaust gas temp
7) Set governors or limiters for a valet or anti theft mode
8) Remove road speed limiters
9) Clamp voltages so the ecu doesnt go into limp mode
10) 5 Complete sets of maps switchable while driving (this isnt just a +/- fuel figure for the chip, it is a completely different tune that can actually be setup to run a different car if you swap the chips around on your vehicles)
11) Run a water/methanol injection system
Thats 11 features quickly off the top of my head I could easily think of alot more than that, and these are just your run of the mill things I do with a chip. Some of the more detailed things I use them for would boggle the mind of most people.
So yeah 10x more features than anything else out there and thats not opinion, thats cold hard facts.
