When I am on the interstate about 80 mph and not boosting I see around stoich but as soon as I step on it and enter boost I instantly go into open loop and get good a/f readings even if I am only boosting at like 1 psi.

Yes, I believe that I am in open loop at the time. I may have to make a run tonight just to make sure.

I can't find my wiring diagram and I can't read this image. Can you point out C20-81? I'm wired this way.

LtNoogie · 04-13-2009, 11:32 PM

Interesting. Where did it go to on the fuel controller connector?

Here's the wiring diagram that I just pulled off their website. It looks like my V1.3 wiring diagram.

Even if you did run bigger injectors ( i dont know why you would ), you wouldn't want the tc ones. Either matrix or corolla you would want..I think.

Just wait, Noogie is going to be running larger injectors soon and he's going to let us know how it goes.

*My gauges came in today! YEEEE. Don't know when I'll get to install them though...

why not? they worked fine for me.

PETERPOOP · 04-16-2009, 02:15 AM

I think it was mentioned earlier in this thread or another, but it was said that the car would run worst with tc injectors. If anything, only would be good at WOT, but at idle and normal driving, TC would be too much.

If blitz doesn't offer us different fuel controllers with some success, when I get the greddy ultimate, i am going to talk to the tuner and try throw in some tc or matrix/carolla injectors with the 1zz throttle body and tune it accordingly.

Garm, what size are the tc injectors. What AFR were you reading at idle?

"it was said" isn't the same as "it is so".

I'm not sure on the size, noogie -- throw them on and see how your car runs so we can settle this. I was normal AFR at idle, 13-14. Did fine on the dyno too, except at WOT over 5k rpm

true, this is true.

tC injectors seem like a big jump to go and "try" out. Might be safer going to carolla/matrix injectors , seeing how those run, and if everything is fine, maybe move up to tCs?

Go for it noogie! haha

whooppee777 · 04-16-2009, 02:15 PM

kcalb is going boosted with blitz very very soon and i know he has a set of tc injectors. im sure if he has issues he will swap out injectors and let us know the outcome.

cali yaris · 04-16-2009, 02:17 PM

if the car runs ok and there is an a/f gauge to watch, trying them out should be ok if done carefully.

I don't know how much larger the tC injectors are but they aren't huge. I am pretty sure that the Greddy turbo kit for the tC comes with 330cc injectors -- so the stock ones must be smaller than that.

LtNoogie · 04-16-2009, 02:18 PM

I'm test fitting injectors from RC Engineering into the motor on Friday. It's only a fit check to make sure everything bolts down because the injectors are physically bigger than the stock ones. If they fit, I'm working with them to decide whether to install 240cc, 270cc, or 310cc injectors.

That's why I keep asking people what size injectors they are installing and whether they are having any problems at idle or under light throttle.

kurokoma-kun · 04-17-2009, 11:47 PM

FINALLY getting my gauges installed!

Here's how they look in the mounting plate I made from some copper sheet--it took a little fitting but the lid to the compartment does close completely, and I get to keep the little rack on the left for car wash quarters! I'll be finishing the electrical wiring tomorrow (forgot I needed inline fuses

).

PETERPOOP · 04-17-2009, 11:50 PM

So you plan on driving with the compartment open?

yes.... and closing it when I go to get my emissions test done

just one reason for concealing the gauges. The open lid doesn't block the view in any way, and isn't all that visible from the outside either

PETERPOOP · 04-18-2009, 12:02 AM

nice nice. what colors do yours light up? red?

I am putting my gauges and wiring them up tomorrow too! We should have some nice pics for people tomorrow.

kurokoma-kun · 04-18-2009, 12:07 AM

Yup red, though I kinda wish for blue now! Can't to see yours
