Supercharger + Engine managment system

[NFSP TC]

I got a TRD supercharger with various mods. I had a wideband dyno done and my car runs stupid rich above 4300 rpm. I am considering a E.M.S. as a future modification. Is anyone currently using a E.M.S

if the supercharger was dealer installed, they should have reflashed your ecu. If it wasn't dealer installed, take it into the dealer and pay them to reflash your ecu (or send it to ZPI). the dealer reflash isn't going to give you the perfect settings, but it won't run "stupid rich"

What was your a/f ratio in that rpm range?

[Krazylowgsx]

dont send your computer to ZPI.. your car will be down for MONTHS!!!

you could use an Emanage, stand alone, or even a SAFC

[Krdshrk]

SAFC doesn't generally do too well on the tC from what i've seen posted on forums. The 2 best options right now are the GReddy Emanage and Unichip.

I know of at least 3 people who have the S/C and Greddy Emanage.

i would hope your not running your s/c without at least the TRD remap.

did you add an intake? from what i read that screws the A/F to hell

[Krdshrk]

Adding an intake would make him run Leaner, not richer.

[NFSP TC]

I did add my own custom short ram intake. And when the S/C was install they did reflash the ecu.

Adding an intake would make him run Leaner, not richer.

yea but i figured why not.

I did add my own custom short ram intake. And when the S/C was install they did reflash the ecu.

then you shouldn't be running rich at all, at least not excessively rich.

What was your air fuel ratio?

[Krdshrk]

Optimal A/F is around 12.0 for F/I cars...

[Stryker Trailwood]

yea, i would be thinking that if anything he would be running lean..

[NFSP TC]

They havent forwarded me my data sheets yet but around 14.2/1

[Krdshrk]

That's lean... that's not good.

[Stryker Trailwood]

isnt that what the stock NA tC sticks to when under WOT? 14/1?
:crazy:

[NFSP TC]

Im not sure. I know when I drive hard I puff a little smoke when I shift.

[Krdshrk]

My N/A tC was running 11's for A/F on WOT.

[Stryker Trailwood]

i very well may be confused with something else.

[NFSP TC]

btw, i got some of my information wrong in an above post. I was running 14.2:1 AFR's cruising. I looked at the dyno plot, and I was running a bit below 10:1 at WOT in boost. So yeah, I'm running quite rich.

[2dot4]

10.1 isn't terrible because you're running low boost with bigger injectors and a reflash. get a stage 1 pulley and you should lean out a little. or go buy a unichip.

[Krdshrk]

Yeah you can bump up the boost a little bit and see how that works for you.
