So Im used to the haltech but now Im going to stock engine and car, but want to get a piggyback to control the extra fuel for 850-1200cc injectors. What is the best system for this. Possibly keeping the a/c and other idle control so just looking for a piggyback system.

 

You could do an Rtek inconjunction with an additional injector controller( HKS).

Why did you get rid of the haltech/BP engine setup?

 

The engine blew after a rotary meet, and I sold the haltech to get the extra 500 for a stock tii to grab stuff out of to put in mine.

So why would I need an extra injector controller with the rtek? Does it not control fuel or just a certain amount?

 

You can only do 720cc x4 with it. Not enough fuel for a T67...

 

Presets are only 720/720 at maximum on the stage 2 Rteks, but fuel can be adjusted up/down by as much as 37%. 850/1000 is doable on it, if we're talking an S4 ECU (not available for S5 TIIs). Of course, this can be a little more expensive route than a stock ECU (or Rtek stage 1) + an HKS controller or an SAFC.

 

I didn't know that, thats not bad for $500...

Hks AIC is generally in the $200 range, however you can't control timing if you run stock ecu...

 

Emanage Ultimate!

 

it seems they only have harnesses for the rx8 though, unless the regular harness can work.

 

Rtek.
