Hey guys, I was just wondering if there's anything I can do on the settings for the rtek 2.0 to improve low end throttle response and street driveability (2000-3000rpm).

I'm running 720cc x 4, HKS Dragger exhaust, stock s4 turbo (upgrade soon) peak at around 10 psi.

Will running 500cc primary and 720cc sec. help? How about riching or leaning the fuel map?

BTW, will a S5 turbocharger make a lot of improvement compare to a S4 turbo?

Thanks

 

s5 turbo does make more power but not enough to make that big of a difference 550s might help ull need a wide band to see weather or not you will need to richen or lean the a/f ratio out and if your not expeirienced i wouldnt go messing around with the ems take it to someone to get it tuned thats the best advice i can offer you

 

Thanks for the reply. Yes I'm looking into innovative wideband o2 sensor for tuning. Most def. on the wideband when I get the turbo upgrade.

Do you think lighter flywheel help low end?

 

Is your user name accurate? If so, I'de love to see pics (I had a '72 before I got my TII).
2000 is getting to the lugging end on a TII. As for settings, tune the fuel map with a WB.

Yes, I have a 71 Datsun 240z with a RB25det swap. Everything is in the car already just need to wire the whole thing up. I took out all the stock wiring because it's shorting everywhere so I got a EZ wiring kit. Haven't work on that car for a long time, it's just sitting in my garage. Hopefully find some time to work on it and make it run soon!

As for the rx7, I'm going to get a WB for tuning in the near future.
