Petyd, for us noobs, about how much does the whole rigamarole cost including all the parts,installation, and tuning?

I used the internet and did some pricing to find the minimum reliable cost of a turbo kit and parts (I didn't include taxes or shipping).

Parts: $3210
-ZPI stage 0 turbo kit: $2670
-RC 550cc Injectors (I couldn't find the 410cc ones): $395 from ZPI
-TRD ECU reflash: $105 from ZPI
-Transmition cooler: $40 from Summit Racing

Installation:
Tuning:

I also see a "greddy emanage" on ZPI's site for $305. I presume this would be better than the ECU reflash?

 

ZPI is supposed tos start selling some 410cc's if not contact Toyo and see how much just a set of 440cc injectors for the tC would be. that + trd reflash+ zpi stage 0 + tranny cooler. NOTE! the TRD Flash WILL NOT! work with 550cc's it is designd for 440s!!

 

www.deatschwerks.com has the 410cc injectors.. Call them to order.

 

The website only has Nissan, Subarau, Dodge, and Mazda. Could it just be out of date?

 

Or hit them up on AIM if they are on.. DeatschWerks

 

If you are going through the trouble of doing the TRD reflash be sure to get the specific one for the A/T. Do not assume the TRD reflash + injectors + turbo will take place of an actual tune... Unless someone actually gets data that support this.

 

^ Exactly, ZPI should R&D it though.

 

I think we need to do our own R&D. I'm tired of getting bad information.

 

^ Or that. You have really been helping the AT guys lately. Keep up the good work.

 

yea i know joe meyers here in houston has the a/t reflash. so if somone wants to do it locally here in texas i can probably arrange it.

 

Skip the TRD ECU reflash and go with a better management system.

The TRD reflash is a stock map and it's terrible - I do not consider it "Tuning" at all. Get a fuel management system and use it.

 

You need to tune any aftermarket turbo kit, especially if it's not FI from the beginning. I don't care what anyone says. Slapping on a turbo and saying the stock ECU will work is just insane and People buying turbo UPGRADEs still need a new tune. How could going from nothing to a turbo need nothing more?

You need at least something that tunes your WOT. Stock partial throttle tuning will pull some ignition timing, but not under WOT. Partial throttle will always average 14.7AFR and your WOT is up to your engine management. Leaving it lean, with stock timing, under wide-open throttle is just asking for failure down the road.

 

Stage 0 kit has a 2.5" MAF pipe -Just like the Injen CAI pipe (Go measure the neck-down). If a 2.5" pipe is this secret component is what allows the Stock ECU to magically adjust all engine parameters to run on a 6 PSI turbocharger I'm going to go into a comma!

Actually the 2.5 MAF pipe will pull timing up on the high-end -but it's still not enough unless you got the fuel to go with it.

Wake up folks -Turbo's need tuning.

I did install the 550cc on the Auto tC last night -No issues. I'll probably spend most of the morning getting all tuned up.

 

Here is my e-manage blue injection map for ZPI Stage 0 with stock injectors on an Auto Scion tC.

This works good until you beat on the throttle in 3rd gear 370cc injectors(stock) are basically 100% duty cycle the moment you really get going. But it's better than nothing. Stock ECU will not be giving you a whole lot of fuel till you get close to red-line.

I have been runnig this map for a little over a week and I've kept a log of A/F and ECU fuel trim adjustments and the ECU is not doing anything to overide my map. It's basically set for Open-Loop correction and only does it thing when under boost because it's the only time you can get the MAF voltage to those levels. When going down the road at 70 MPH at no boost you will get a perfect 14.7 A/F. With this map I'm getting 23-24 MPG which is as good as stock (for the way I drive in my driving conditions)



Hope this helps someone not blow there engine up. Moral of the story -Get tuned! and if you have Stage 0 -Do not beat on your engine unless you got some bigger injectors and are tuned.

 

Thank you for backing me up .

 

Joe, I see one of your S1 auto kit also includes an e-manage with a base map. Does this mean that some turbo kits are pre-tuned out of the box?

 

All of our turbo kits ship pre-tuned.

 

Our base map that is included with our system is quite comprehensive and will be VERY easy for any well versed tuner to tune on your vehicle for optimal performance. Our base map is designed to be rich, safe and quite conservative.

 

What auto from ZPI has put down 230whp?

Dezod base map is VERY VERY safe. I ran it for 3 months. You could run there base map all day. There base map is for safety not power. Once you get it tuned, its a whole different story. I put down 227whp on the tune and with stock mid pipe. People say all day about ZPI pushing it to the limit's and this and that, im telling you few more day's and you will see the limits pushed. This whole discussion somehow turned into a Stage 0 A/F bull crap. Go Big spend cash or Blow your ____ up.

Dezod kit is more expensive then ZPI because you get intercooler, intercooler piping, injectors, tranny cooler, EVERYTHING you need.

Im not trying to throw no damn sales pitch but I get sick of seeing ZPI Stage 0 stuff when people are just looking for the cheapest route.

Im sorry but people just have this image imbedded in there mind that ZPI is the AUTO GOD! No dis-respect to ZPI or am I trying to bash but I dont think that they are the ____.

Thats my opinion. We will let the numbers and the safety speak.
