Installation

Fast guide to Smarty software levels

The horsepower settings have a modified "Torque management" ( TQM ). The throttle response is greatly improved but is set to a safe limit. With "Safe" I mean safe for your tranny and rest of the driveline.

  • SW # 1 : 40 Hp increase
  • SW # 2 : 70 Hp increase
  • SW # 3 : 100 Hp increase

Tested on stock trucks on a Dyno.
Stock means just that. Stock! Even the air filters were stock.

The trucks were S T O C K, even the wastegate settings!
Smarty Performance King checked the "baseline" ( the stock truck Hp at the rear wheels ) twice in a day in order to be sure about Smarty Performance King findings.
The above declared HP numbers are all rounded down to the closest number.

Yet, Smarty can not do one thing for you. Fix what others have broken. Smarty can not restore a key on counter that another downloader has erased. Smarty can not fix VIN# troubles caused by other products. If your Check engine / ABS light is on because another product has screwed your ECM, Smarty can not fix it, the other guy HAS to.

ABS / Speedo recalibration
The tire height can be adjusted up to 44" in increments of 10 tenth of an inch in just a couple seconds. Of course, Smarty needs to be VIN# locked to the truck in order to get into the ABS adjustment section.

DTC Code reader
The name says it all.
You can read and erase codes. Codes are displayed also in plain English. That's old news by now. Smarty S-03 was the first one to provide that utility, others found the idea to be a good one too. (Smarty does erase ABS codes too but does not display them)

ECM update speed
Faster than anything else on the market! Again they've done Smarty Performance King homework on the protocol. Less than 5 minutes. Three times faster than a Star-Scan diagnostic tool or competitor.

They have developed Smarty Performance King own bootloader in order to not have to pull fuses should an update become interrupted for any reason.
All you have to do is to turn the key off / key on Smarty does everything else on it's own.

Updates
The CaTCHER softwares as they are today are only a starting point. Expect major news in future.
