Whew…how could I have missed all that! (sorry folks, will dig deeper next time)
Anyway, what this ‘thing’ does (according to a few of the posts above is:
“these are typically just resistors that trick the ecu into thinking the temps from the iat sensor are cooler than they actually are, causing the ecu to dump more fuel. it’s basically like running the car in warm up mode or with a choke on.”
(I leave the original post below and hang my head in shame)
Have a look at the Surge Performance Chip (available from yourhotcar.com among other places). It claims to add up to 35 Horse Power (from 7-10% gain in power from stock) and 20+ Ft Lbs of torque.
Like all good performance chips it is fully adjustable for either Horsepower or gas mileage by using a knob (yes a knob)
From the yourhotcar website:
Fully ADJUSTABLE performance chip designed for your vehicle. The Surge Module will not only compete with other higher priced Jet V-Chip, but will OUTPERFORM it. The
Surge module is designed with the finest, most precise components
available out there today. Giving you the option to fine tune it to
your favorite setting. Our modules are designed to be used in any
weather condition. Doesn’t matter if you live in the east or west
coast, the module will still perform as advertised. Step by step
instructions will be included along with all necessary hardware to
complete the installation. You don’t need to have any mechanic skills
to complete the job. Takes no longer than 15 minutes.
The Surge performance chip simply wires into the factory harness of the IAT sensor and just provides a new signal for your cars internal Electronic Control Unit (ECU – all modern cars have an ECU to electronically manage and monitor your vehicle’s performance, by default they are tuned to government regulations…which means that they are inefficient!) You could replace the ECU (at a cost in the $1,000′s). This performance chip negates the need to replace the ECU by giving the existing ECU an external controller.
According to surge, it takes only 15-30 minutes to install and can easily be removed or re-installed at any time.
I don’t know about you but this sounds like a mod for anybody!
Pass people, pass!
