Quick question I know someone already probably asked this but I didn't find anything so here it goes I have and 06 tc and I already have a injen CAI. So will I have to get rid of the intake and leave the stock one on for the supercharger? I heard that It has a possibility of not fitting any help would be highly appreciated!!!! I am also installing this kit myself and getting zpi to reflash or possibly toyota whichever is cheaper.

 

yes, the supercharger will come with its own airbox intake that will replace.

and you don't want a cold air intake or sri on the supercharger because your a/r's will get too lean.

 

However couldn't I ask zpi to change the afr setting since they are tuning the computer?

 

they aren't tuning the computer, they are just reflashing the engines ecu for you to the trd specifications. to tune it, you would have to add a piggyback ecu like emanage or unichip and have that tuned to change the a/f ratios.

 

Damn more money!!!! Is it really that bad though, I mean I'll just run lean and blow my engine lol!!!! So I shouldn't pay to reflash I should just run something like an emanage?

 

trust me, you don't want to mess with your supercharger until you are 100% sure it is in good working order.

there are MANY people crying about their superchargers having all sorts of problems with both stock and modifed tc's.

install your supercharger, get it reflashed, if you install it yourself you have a year of warranty, if it lasts that long problem free, then you can start working on it since you don't have a warranty left anyway, you can go all out with a 9 psi pulley, headers, exhaust, and a modified sri or cai intake, and get it tuned with emanage or unichip or whatever floats your boat.

my friend sapan has the trd supercharger on his tc, and got it tuned with a unichip and it makes 225 whp with the stock intake and 7 psi pulley. all he has is trd exhaust which isn't much bettr than stock.

 

Damn 225 how did he do that?? What about those rippmods cams I heard they help out alot and they don't go specifically on the supercharger. Sorry about asking so many questions.

 

well, from what i've heard, the trd map is pig rich in just dumping fuel, and it is really conservative, so there is alot of room for improvement.

and the ripp mods cam is mae specifically for superchargerd tc's, infact, it is the only off the shelf cam shaft made for the tc, and it delivers a 15% increase in hp.

 

would I need to reflash the computer again?

 

not sure, you'd have to ask them.

the point of the reflash is this, your tc has gone from n/a, to making a peak boost of 7 psi. it needs to know how to properly add fuel to the increased volume of air and when to ignite the spark plug. that is what the reflash does. the cams open and close the intake and exhaust valves.

but tuning is a good thing, keeps everything much safer.

 

But how do you tune if I just have the trd so do I get the Emanage or what I am confused.

 

alright...your scion has an ecu made by toyota to properly run your engine. based on the air flow readings from the mass air flow sensor, it adds fuel for proper combustion in the cylinders. now, you are adding a trd supercharger, which is a compressor, larger injectors and so on. your ecu is not built to operate with any form of forced induction be it turbo or supercharger. now, to work with the trd supercharger, there is a trd ecu reflash, which is a brand new fuel map for your car to properly run with the supercharger and the increased volume of air that is going to be forced into the engine.

now, in the interest of safety and reliability, trd made a very conservative fuel map to minimalize the chances of the engines damaging themselves with conservative timing and pig rich fuel maps.

so first, with the supercharger, you'll need the trd reflash PERIOD. you can just get it tuned with emanage, but that would be stupid to try and get the emanage to tune the stock non-supercharger compatible ecu, that would be alot of extra tuning, and very dangerous. you get the emanage or unichip, whatever piggyback you choose to tune the trd fuel map to make more power with additional add ons like upgraded pulleys, cams, headers and intakes. there is some decent power to be made with the supercharger, but any modifications will void your warranty. with the exception of something like s-pipe back exhaust.

 

ok now you make sense. Thank you I'm sorry I am running half steam today. Appreciate the info!!!
