I'm not bragging anything, not looking for haters... Just sharing info to the community of car enthusiasts. Please do not comment anything about boost is better... price vs Hp... or anything negative... Show respect and receive respect.

Thanks for Viewing!

 

Love na. Good luck with build. How do you have the proefi hooked up? Also what model are you using proefi 48 701 or proefi 48 705?

PRO48 705
Its hooked up via custom harness that plugs into the stock harness and have an Innovate wideband wired to the pro48.

 

Gonna run pretty lean with the tb at wot. You probably already know tho. Good luck bro keep us updated.

 

Here is my take on the RX8 TB:

Throttle response is noticeable from stab to redline.

I do have a lot of rev hang when I disengage the clutch, I've already started to experience this when I changed to a light flywheel, now the rpms don't drop between shifts. Tuning for the TB should fix this.

The car did get leaner, AFRs was running 12.4 @ wot now it bounces around 15.

I do not have the coolant lines hooked up due to the length of the coolant lines, this seems to only affect cold starts, mine idles at 3k till warm (30secs or so) and goes back to normal.

Waiting to schedule another tune to get everything smoothed out and squeezing a few ponies.

 

Until you have dyno sheets there will be "haters" just prove what you got on paper

 

You should check out tcpete, he did a push with N/A.

 

I certainly have, I've dug everywhere and talked to my tuner about how to go about this, so I do have a plan.

This will get done, my biggest issue is there is only 1 tuner within a 5 hour radius that can tune the PROefi systems, lucky he is local but very very busy. Just waiting for the OK to bring my car in.

 

Hey man what kinda gains did you see with the throttle body?

 

I can't produce hard evidence that I've made more HP just bolting it on until I get it retuned and post numbers. But I can say is the car is very noticeable in throttle response and feels more aggressive in the high rpms ranges.

 

do you have stock intake manifold ?? is it ported or just stock?

 

Yup still on stock intake mani. Didn't mod it either.
