i did a search on it, not too many threads popped out. i know most 4th gen people doesn't have this device, but i thought this little monitoring device serves a lot of function. it is useful to both n/a and boosted car to keep track of their car. the unit delivers the following standard functions: Engine RPM, Vehicle Speed, Travel Distance, and Battery Voltage. in addition, Stop Watch functions, Best Time Memory, RPM Warning, Speed Warning, RPM and Speed Outputs are included. it also monitor data such as vehicle speed, engine RPM, and elapsed times.

anyway i'm just curious if any of you have experience installing the RSM. if not, is the installation similiar to s-afc? do you guys think it's a good device for $200 shipped at my door? any other comments you guys wanna make?



p.s. it also get rid of your speed limiter completely

 

Pretty simple to install, you just need the wiring diagram for your ecu so you know which wires to tap -- speed, rpm, etc... Make sure you get a g-sensor if you want it for 1/4 times and all that. I just wanted to be rid of that pesky limiter, so it just sits in the glove box.

 

yea..i'll probably pick it up for my christmas gift

 

Might as well get an SAFC-II so you can fine tune your air/fuel as well...

 

Can the SAFC-II remove the speed limiter too ?

 

yes it does.
