It's been a couple of years since I have paid any attension to rx7s. My is still broken in the garage after I blew the motor 3 years ago.

I just learned that the long awaited Rtek has been released for S5TIIs. I couldn't believe it when I read about it.

So here is the question. I did some searching, but I'm still a little confused.

Rtek does not change the stock fuel map. Does it mean it does not change the stock fuel map under stock conditions?

What happens above 9 psi for fuel? I know that timing is retarded. But what about fuel when the engine goes beyond 9 psi?

 

only the stage 1 is currently available for S5TII. Stage 1 chips for the most part, do not alter the stock fuel curve. The ECU still uses the MAF to calculate fueling requirements, which is still active beyond stock boost. But as always, depending on your mods, the stock fuel curve may/may not be what your car needs.

 

stock s5tii turbo w/ ported wastegate
stock motor
11 psi
Crane Hi-6 CDI for each of the leading plugs
walboro pump
550 pri/680 sec (can be replaced with 720s)
safc
apexi avcr
paul stokes FCD
3" TID w/ K&N cone filter
racing beat turbo back exhaust (no cat)


is my current setup

the rtek seems like the ideal setup because then I could get rid of the safc and fcd which is kinda rigged... I have hte safc reading off of the pressure sensor to try to follow the pressure sensor and all correction based on pressure instead of TPS.

based on your r&d, what is the expected AFR at 11 psi? According to your site the expected timing will be pulled back 2 degrees at 11 psi? What about the trailing split etc?
