Since rtek hasnt made a chip for t2 s5s is the only other choice is to buy the expensive standalones?? or is there other companys out there?

 

the emanage ultimate!

 

buy my megasquirt setup... 325 shipped, plug and play, includes a stock ECU modified so it does ignition and megasquirt for fuel.... will toss in air temperature sensor too
all you do is hook it up, run 1 wire for rpm on the coil, and another for vacuum/pressure signal
thats all

 

You could get by with an SAFC depending on what your plans are.

 

Corksport also makes a chip.

 

I got a HKS PFC F-Con for $125 on ebay. get the graphic controller for $100 on ebay too to adjust the preprogrammed settings
