so why are you buying a turbo kit? to street race like most others? i would hardly consider that a better reason. i do like the show quality of a turbo kit as well, but i liked the sound. i couldnt see buying a cheap mod from ebay. now that ive put it on i enjoy the power but hardly find my self in boost to start with. im unfamiliar with the aem stand alone but from what ive heard everyone is raving about the hydra. on top of that most heavily modded cars have a stand alone ecu, not factory. emanage tricks your factory ecu. your factory ecu also learns from your driving style etc etc. it tries to save gas as you go and therefore it fights your tune. never said it looses it. basically i can tell when i need to reset my ecu because i can no longer partial boost. it gets jumpy. once i reset the ecu drives like stock again with full partial boost capabilities. maybe im crazy but im definitely not the only one who has to do this.. its really blown out of proportion and is not that big of a deal. and on top of that having a bolt on turbo kit on a scion is not highly modified..

the difference between a standalone and a piggy back is the world. with a piggyback your stock ecu is still controlling the motor the motor. the piggyback ecu has wires that are spliced into the factory ecu and basically takes your cars sensor inputs and changes them to make your car think its running leaner then it really is. this way your car corrects by dumping fuel.

a standalone ecu is directly connected and controls all engine functions such as idle, cam and valve timing, afr so on so forth. there is no tricking involved, it directly controls these. but standalones are usually high dollar, 1600 and above. hydra right now is roughly 1800 i believe but its supposedly the best and if i ever get serious with the car and want to track it that will be the route im going. but i wont bother with that unless i do internals of the car to get the full benefits of it.

im not trying to start an argument with someone else or you but we all have our reasons for modding our cars as we do. i find one part sufficient enough and if someone else does not like it they can choose to not use it. also everyone is on a budget. my budget has been tapped for motor supplies and i dont see myself doing anything for a long time. hope this information has been helpful to you and if you have any questions feel free to pm me.

 

You do know that Partial Throttle (Full Boost) is a bad thing... right?

 

never said partial throttle full boost. partial throttle boosting at all. and its not a bad thing if you have a stand alone because it has the ability to fully control your car. if i full boost in 2nd my tires just give way, so i partial boost, 4 to 5 psi. if its jumpy, i need to reset the ecu. normally its just fine..

 

never said they were heavily modded imports i mean liek 03 cobra with kenne bell pushing 615 to the wheels my other frined with a 74 camaro with 585 hp im more fo a muscle car guy but the scion tc is so damn clean lookin my girl needs a car so she might as well have a 400hp one to drop the kids off at school right yeah mostly for the street racing aspect of it, and not knocking what your doing, just saying its kinda like buying 4 12's for the car casue they look cool not so much cause they sound good idk, to each theyre own personally for me just the sound of it isint worth a couple grand, like i said my opinion... so 1800 bux huh thast steep i wonder how well it stacks up against the emanage ultimate, i guess really no comparison, and if your car fights the tune set to it how much is is costing you to fix it every time or do you just push a couple buttons on the ems...

 

just gotta reset the ecu. takes 1 minute. and its not necessarily every 2 weeks. sometimes longer. just depends on how your car is running. you will know when you need it. unhooking the battery is all it takes.. emanage ultimate does not stack up against a standalone. a standalone is a brand new brain for your cars motor. they are in a league of their own. also as far as high horsepower v8's they are in a different world. the computer for those are much different then for the scions.

as far as just sound yes that was the main reason, but also for show. anyone on here who has seen my car in person will tell you how clean i keep my car. i keep it spotless. but i wanted a better look under the hood and since i only paid 3300 for the stage 1 zpi how could i pass it up? its 5 grand brand new and a local guy here was selling for much less.. i personally would not pay 5g's for the kit but i think the 3300 was well invested. and talking about buying speakers ill give a good example. alot of folks buy 4 speakers, and fire 2 of them inwards, or all 4 of them inwards to show off the baskets. thats for show. some people put 40 or so speakers in the trunk like that other tc on here. could be for show, or competition. i think hes set up for show though, dont quote me on that. just depends on what you like. i like the look of my motor, i love the sound of the turbo spooling (never heard that before, i never even rode in a turbo car before i bought the kit).. and i like the open dump tube. so im impressed and happy. so whatever makesyou happy go for that. honestly though if you have the money, go standalone. it will eliminate alot of hassle and tuning is more precise..

 

I understand what you are saying about the ECU reset, but the ECU has Three things in it:

1. Base map with rules for variances
2. Long term map, this takes weeks to create and is not wiped out when you reset the ECU.
3. Short term map, these are learned in minutes and have to do with current temp, ambient temp, humidity, octane of fuel, etc.

Resetting your ECU to get quality partial throttle boost to work properly is like removing a trial program and re-installing it because you don't want to pay for it. It's a bandaid and is not "fixing" anything, it's only delaying the inevitable. GET YOURSELF PROPER SENSORS, and TUNE YOUR CAR PROPERLY.

 

i know you keep preaching this and i will no longer feed your ignorance. once again, buy me a hydra and i will happily change it out. considering ive been boosted over a year and a half now with no issues i think im doing fine. besides, i like band aids!!!

 

Dyltone,
When you say get proper sensors and tune properly, are you meaning standalons are the only option? Or do you mean different sensors along with a piggyback, like the emanage?
I was thinking about getting dezod's black box to help with partial throttle boost. what do you think?

 

i have dezods black box as well. it does fix the partial throttle tuning as well, but its not a fail safe. same results. i had zero partial throttle boost prior to black box. installed the box, great partial throttle response. still have to reset my ecu every now and again though.

 

what is partial throttle boost??

 

without the black box its hard to give it some gas with out stomping it. the car gets jumpy. partial throttle boost is you want to accelerate, but you dont want to stomp the gas. basically you either drive like a grandma or its ***** to the wall. there is no middle ground. the black box allows there to be a middle ground.

 

or you can use the pressure sensor and tune off of boost pressure. same results.

 

i would of done that but i heard its not the same as the black box.

 

I've heard that argument as well.
Where do you get the pressure sensor, and how much does it run? Is there a specific brand, or is it part of a gauge?
