What is that bid "S" switch on your dash there ?

That is my custom made "Sprint Booster" switch:
"S" unlit/off = factory throttle response
"S" green = sporty throttle response
"S" red = agressive throttle respone

There are a few solutions on the market,
Sprint Booster was probably the first out there:
SprintBooster by BoulekosDynamic

Definitely worth every penny, imo

Can you give us a quick write up on your Sprint Booster installation? Particularly the button you use to activate the different modes and the way you wired it.

I can try, too bad I have no photos anymore:

1.) Installation was a snap, "theoretically".
All you do is disconnect the ECU gas pedal connector from the harness and plug the Sprint Booster in between.

2.) Without disassembling the driver side dash, duct work, etc....locating the ECU gas pedal connector was, let's say, a challenge.

3.) The cable length of the harness/connector is JUST okay to squeeze the Sprint Booster in between.

4.) I was able to install it by deinstalling the duct work underneath the dash, lots of led lights, patience and a sore back

5.) I heard of a guy, using a PORSCHE switch, soldering bridges, cutting away connection lines etc., being able to link both smd-boards of the switches. Looked 100% OEM as his PORSCHE switch (using the amber/red LED) was operating the Sprint Booster switch.

6.) I tried to figure out, how he could have done it, but wasn't able to, so I went down another road and did a mechanical solution, as the smd-boards are almost identical in size. I was able to open and modify the PORSCHE switch to hold the Sprint Booster smd-board (instead of its original board) while using its super bright green/red (btw. the smd-LEDs seem identical, so one could change the green to the spare amber LED) LEDs to illuminate "ze MAGIC S" (sanding down the black layer, create an "S" ouline, clear coating on top, done). The switch is functional and its LEDs are powered by the ECU gas pedal connector.



pelicanparts and Wayne's 101 Projects book have good information about it, too.

So as a follow up to the earlier post, I was at the indy shop today (european auto surgeons, Maine) and they turned the OBC and Cruise Control on. It took Aaron all of about 15-20 min and in his test drive everything worked as it was suppose to. He then flushed the transmission oil and brake fluid for me. They have a good shop and do good work.
On the 4.5 hr drive home I used the cruise on the interstate and was surprised how well it held the speed I set, with little fluctuation.
The OBC, I got my outside temperature and a lot of other paraphernalia. I tried playing with it a bit on the way home but then decided the road needed more of my attention.

An unexpected outcome of having these 4 stocks is I now have to be careful with my knees. I'm 6' 1" and 32" leg inseam I've hit those stocks getting in or out of the car.

So in conclusion, follow the books and the info on Renntech.org and it should all work out. Its not a real difficult project for a 2003 -04.
