ok guys i am new to the fc world and i am getting my first fc tomorrow. (God willing) and i wanted to find out some information. first things first the fc has a turbo back exhaust on it and an air intake. the guy told me that it boost very quick and it hit the fuel cut off point because he never got a fcd. so i was thinking about getting one of those but then i found out about rtec7. and i found some for sale too. so i was wondering which is better to tune. the safc or the rtec7? or should i get both? i was planning on getting some bigger injectors for the motor something like 720cc. and i wanted to get it tuned so i wanted to see which way is the better way to go with the method of tuning? also is 150 a good price for a rtec7 1.5 ecu?

 

They are two quite different products. If you want to tune, get the S-AFc, because with the Rtek you can't tune at all. The Rtek has some useful features, but you still end up with factiry mixtures.

 

thats what i was thinking because i have a guy that lives about an hour from me that tuned my civic when i did the motor swap he chipped my ecu and all and he was telling me the safc is the way to go but the rtec is good also and i just found out that the guy i am getting the car from has a brand new fcd that he is throwing in the car for me so then the safc is the way to go thanks for the input.

 

I think I have a fcd layin around you want to buy it?

 

nah he is giving me a brand new hks fcd never installed never opened with the car

 

poop

 

Only thing is I wish there was a way you could retard the timing. Only thing I like about Rtek better is that it retards the timing beyond stock boost levels.

 

thats one of the main reasons i got it

 

same here, and i got version 1.7 to run my 720cc secondaries

 

lol

yep thats the other half of the reason that i got it

 

I think the flood clear feature alone is going to be worth the price for me.

I can't tell you how many times that car's flooded on me in the past and made me late somewhere.

I got an SAFC 2 also, I think the car will become a little more well behaved with the Rtek in and the SAFC tuned right.

 

Is Rtek a chip?

 

yeah ... you send your ECU to pocket logger and they send it back to you chipped

 

Go with both man

 

agreed

 

well i got the 720cc injectors today and i am going to try to put them in this weekend and then i am going to send it out ecu for the chipping

 

just dont go nuts with the SAFC settings, everyone sais that richer is safer.... not always! remember that it is tricking the ECU that there is more air entering the engine thus the ECU thinks the car is under more of a load and increasing timing and fuel injection pulse width. the added timing can ause detonation, which i have experienced so a wideband is also a handy investment, tune it moderately not overly rich and definitely not lean.

 

no...

tiomign decreases when u make engine have more air
timing INCREASES roughly 1 degree every 10% you decrease on ur afc

research under the guy who made the rtek - he posted baout it

 

Timing doesn't increase and decrease, it advances and retards.

And Karack is right, the main drawback with AFM interceptors is that they all effectively advance the ignition timing as you lean out the mixture. The ECU retards timing as load increases, so if you use an interceptor to tell it the load is less so that it injects less fuel, it also doesn't retard the igntion as much as it normally would. This is why you shouldn't use interceptors to correct for huge injectors. The large corrections have an equally large effect on igntion timing, pushing you closer to detonation.

 

i am going to have it tuned by a pro! so i know he will do it well he did my civic and had it running really good and he has done many of my friends cars! thanks for all the info!

 

Good to know. Since we're on the topic and since I cant get the Rtek I got a question. Since I got the s5 TII I pretty much have to go with SAFC. My setup wont be too extreme so I dont really want to go with an EMS. I'll have just an s5 13BT ported with the racing beat porting template. Full turbo-back exhaust, TID, intake, FMIC, 720cc secondaries, walbro pump. I plan to keep the stock turbo.

Alright to my question now. How much boost would you say is safe to run with this setup with proper tuning? I'm asking because of the stock ecu not retarding the ignition after about 9-10psi.
