I know some people are running a stage 0 kit with stock injectors, without a BOV and without emanage on a stock ECU. I just want to know how would the stage 0 run with the TRD 410 injectors and TRD reflash ECU?

I also read some where on SL some was running a Treadstone kit without an emanage. I wonder how was his kit running, and how would it run with the TRD reflash ECU. I'm looking up this info for my little cousin that's going to take out his supercharger and buying a ZPI stage 0 kit from this Dude.

Sorry for the dumb questions guys but I'm trying to help all my friends and My Fam

 

running a turbo with stock injectors is going to make it run really lean. it will run better with an engine management system as well since the fuel curves should be set up different for a turbo set up.

 

I am running the Treadstone kit, have been for a few months now. It is still running pretty good. At the moment its still running without management because I have not found anyone in the KC area that has much knowledge of the tC's or the AEM F I/C. I have the AEM F I/C and the AEM Wideband installed. As soon as I find someone reliable to tune it Ill have some more info about what the kit does with management. I do not know much about the ECU reflash or how it would effect this kit.

 

Well the stage 0 runs on the stock injectors and i have never heard of it running lean...thought i have heard of nasty backfires...lol

I have wondered my self if a turbo could be run off the trd reflash BUT who has an engine to blow up for the sake of science and research...

It's the Greddy kit, and only at 5 PSI, but it can be done. :D

 

your car can run on stock injectors and no fuel management, but why risk it?

It's like putting a condom on.... Just do it!!!

 

I would deffinitly not run a stage 0 on the trd map, the stage 0 spools more boost at lower rpms than the trd s/c does so running lean would be a problem. I would do either a stage 0 with no fuel managment , or if you run larger injectors you would want to go with the aem piggy back so you get a smoother idle with the larger injectors.

Why is he getting a stage 0 ? he could just do a smaller pulley with meth injection and make some good numbers for less than what he is gonna lose on selling the s/c just my 2 cents

 

So whats up with that anyway, you can't run a stage 0 on bigger injectors and the trd reflash but you can run it just fine on the stock injectors and the base N/A map??? this car is A$$ backwards!

 

first of all, the zpi stage 0 is not availalbe any more, so unless your getting a used kit, forget it. ZPI is out of business.
Also, the trd reflash is for the SC, it will not work with a turbo setup. Stock is better.
Furthermore, i believe the ECU reflash is a one time deal so you can't even go back to stock without getting a hole new ECU which is major bucks.

Youd be better off getting a kit with some sort of managment (greddy blue, aem F/IC, whatever) and trying to tune it off the reflashed ecu. just spend the money and do it right.

washout:
I have the AEM F/IC and my tuner never had any experience with it OR the tC, but after a week, he got it running OK. He's getting another tc with AEM F/IC so once he get's more practice, i'll bring it back for a retune.

Oh, and when they say the satage 0 with stock injectors runs lean, that is at partial trhottle. at WOT, it runs rich, just like any other low boost kit with stock injectors and no managment.

 

I run a 10 to 10.5 at partial throttle and 11.5 at WOT. Stock injectors and ECU.

 

for the stage 0, i ran without management and stock injectors for over 6 months, and my afr were near perfect.....i would recommend getting a bov to prevent large pressure spikes.....and why would you want to run a turbo off the trd refash which is made for the s/c......@ 6 psi, you don't need new injectors for the stage 0.....for rough idle, you just need colder step spark plugs.....if you're on the trd reflash right now, i would just recommend getting a piggyback engine manageent, and if you're on a really tight budget, i would just get the greddy emanage blue....its decent for what it is....remember that you'll need to get gauges to monitor daily driving, so factor that into your cost....

 

Really? 10afr partial throttle with stage 0, stock injectors and no management?
Then why was everyone who was upgradeing their stage 0 to stage 1 saying you needed the pressure sensor with the greddy blue in order to tune partial throttle?

 

There has been some debate on tuning with pressure sensor. Dezod and according to rythm (if i remember correc tly) said that Kenny agreed that it can't be done. But , yeah I'm running 10 to 10.5 partial throttle according to my AEM with sensor mounted the required 36 inches from source.

 

I was running pressure sensor just fine to tune part throttle.

 

What was your partial afr before you got the sensor? One of the guys in the club has the Dezod kit at about 9 lbs and his partial afr is fine as well. he ,of course ,has emanage for WOT.

 

I had everything installed at the same time.

 

oh yeah ,i forgot about that.

 

Wait so you are at 10 at "partial" throttle WITHOUT the Dezod box or any kind of partial T tuning?? so whats the point of the BB?

also knight, you running an intercooler?

 

yep , so far. No intercooler yet , but it is my very next project.

 

I have the same question.
Looking into a treadstone kit.

I dont know why the reflash wouldnt be good when running boost. It essentially is doing the same thing as having the car tuned.

The ECU with reflash sees the supercharger boost to 7 psi and adjusts the fuel accordingly.
Now take off the supercharger, add a turbo charger. The turbo hits 7psi, wont the ecu adjust the fuel accordingly?
