i have two 680's two square injector plugs and two resistors laying around will that work with the rtek

 

see i wasnt sure about the plug dif... i dont know much about s5 since i own a s4 so im limited to knowing what next to do...sorry.. do you already have the resistors??

 

How are you going to use a RTEK in a S5 car? Last I checked, there's no S5 version available. So, you'll need to hack apart your dash harness and install a S4 plug, then use a S4 TII engine harness, a knock box, and swap in S4 electronics (afm, pressure sensor, etc).

 

its a good thing he answered this earlier.....hmmmm...looks like no rtek for you.. keep the FCD bud... youll need it.... good thing someone is here to catch stupid mistakes.....sonicrat to the rescue

 

S5 harness are the same for N/A and T2 ECU. The only difference is one pin (if I remember right 2G). The N/A has a conector to the VDI while the t2 has it going to the knock sensor.

As for running the car on a N/A ECU..... you will have to retard the timing since the N/A ECU doesn't read boost. This will only be a temporary solution. If you don't do this, once you get passed 2-4 PSI, your car will detonate. Also if you retard timing, your idle will not be smooth.

 

Not entirely true, I've ran multiple s5 cars at over 10psi using the N/A ecu with the cas locked in at stock.

 

If you did daily, I would say you were lucky! I wouldn't take that chance. At 10 PSI, I would have it retarded by about 17 degrees.

 

stupid question... but advance and retarding the timing... clockwise or counter for which?

 

locking the CAS at 23*BTDC would be a bit much. I put well over 20k miles on the car setup with it like stock before converting. Though, the SAFC effects timing, so you have to be rather careful watching EGT's, it's all dependent upon your setup and how your car reacts, but I've never had a problem in six vehicles setup that way (definatly not my preference, but some people just want to go and don't want to spend money)

 

should i still run the 720's, turbo 2 ecu, AFM, and pressure sensor just no rtek. i feel i should? what do you think SonicRaT u seem to be very knowledgeable. would i be better of in this set over the N/a ecu

 

Yep, run the TII electronics with the SAFC (and the 720s), and you'll be in good shape. You can reuse your S5 N/a engine harness, so you just need the electronics (ecu, afm, pressure sensor). You will need a FCD if you use a TII ECU, so keep that in mind.

 

i have the FCD in my room all i need is the AFM,ECU, sensor. i responed to a couple people on this fourm i have heard no response. so hopefully soon i will have all the parts installed. big thanks to sonicrat for all the info

 

S5s use high impedance injectors. You can put 720cc injectors in place if you change the connector to match and add the appropriate resistors.

There is no RTek for the S5.

That's ridiculous. I ran 10-12 PSI all day on my stock NA ECU with stock timing. There are plenty of turbo-NAs out there doing the same.

 

i started the car with the turbo electronics and it ran like ****, i put the N/A Ecu in and it ran great. so does that mean the ECU i recived is bad? is there a way to check? i would still like to run an turbo 2 ecu.

 

is it possiable to check if an ECU is still good?

 

thats kinda weird???i cant remeber if you have 550's for primaries???
i through a TII ECU and it ran better at idle...

 

yes i have 550 for primaries. i think the ECU i bad or something because the car ran good on the N/A ecu

 

Do you have an SAFC? Did you change the corrections at all between ECUs?

 

ya all the corrections were set right
