hey guys i have a s4 gxl with a s5 t2 engine as my daily, as of now the engine is fairly stock with an upgraded fuel pump and full exhaust system, i want to keep this car as my daily and slowly upgrade it in the future, my goals are around 300hp with ac and everything that a street daily driven car should have. i am looking at either a 550 or 750 elite series ecu. my question is what computer would be best for my needs. thanks for all the input.

 

The 750, running a 2-rotor, will have 4 more user configurable outputs, one more digital input, and on board data logging. The additional outputs are the unused injection and ignition outputs. The 550 only allows data logging to a laptop, the 750 has on board or laptop logging.

 

Thanks for your reply! im pretty new to this would i need those additional inputs/outputs? i dont think ill be using the data logging feature as this will just be a daily street driven car .again thanks alot

 

Drop me an email. We can talk you through the selection. chris@lms-efi.com

 

I don't think the price difference between the two is that great considering the additional feature the 750 has to offer in the long run.
