Engine is this possible on the 1zz-fe?

is this possible on the 1zz-fe?

"on the vvti motor its pretty much impossible to cause detonation or pings by using the technique like rolling the throttle up to increase timing, the ecu and knock sensor will retard timing before it even gets close to that stage. The vvti ecus are pretty tricked out when it comes to engine management from the factory."

exactly how capable is the stock ecu? is it possible to run a setup with a 2-bar or 3-bar MAP sensor on a 98 MAP ECU along with larger injectors with forced induction? or will the necessary adjustments overflow the stock ECU and make it throw a code?
The Honda guys can run their cars boosted like this without any fuel management:

will this work on a corolla with a MAP ECU?
i asked this on vvt-i.net but wasnt able to get many responses. some help would be appreciated.

Will the MAP sensor recognize anything higher than atmospheric pressure and if so, is the ECU programmed to recognize that? I would think your limitation would be the fuel injectors. However, the stock injectors are rated at something like 185 cc/min (I think). They are rated higher than what is needed for the engine.

you see, all this does is change the scale on the fuel and timing maps. the ECU will see atmospheric pressure when you run 14 psi boost on a 2 bar sensor. but the ecu will also think the injectors are stock, but in fact they'll be approximately twice as large. so in fact the A/F ratio wont be that far off and the car *shouldnt" throw a CEL and adjust when its forced into closed loop mode(i know there are mods you can do to and ECU to do that). but thats what i'm trying to figure out - the bounds of the ECU that will cause it to throw a code, in terms of timing and fuel. i'm also not exactly sure how the intake air temp sensor and the TPS will affect the ECU with scaled maps, cuz i know the timing maps are way different between high and low pressure at the same RPM, and the ECU will think the pressure is half of what it actually is = we tricked the engine into blowing itself up if it doesnt adjust.

wow no one has any opinions at all? did anyone actually read the link i posted, or is it that no one knows the ECU's limits? or is it just that people dont care if they can save money on fuel management when they go turbo....

hey dude...I do care about that and shit i would have saved me the money but I'm loading all my turbo stuff in my cars this weekend well i'm gonna just have the EManage, well mainly since everybody says that other cheaper FMU's don't work with our cars......well It would really help me if you knew wether or not I need to have a return fuel line or would i be ok with a bigger fuel pump? since i did get the Walbro 255 fuel pump...

i guess it depends on how much boost you want to run . guess the stock pump would be ok for low-boost setup, < 5 psi. i would also upgrade the injectors if you can. sticking with no return line isnt a problem, unless you really wanna boost a lot. if youre using the greddy pressure sensor and larger injectors, lemme know what your fuel and timing values are through the rpm range. if this article that i posted is right, then you can get sell your emanage and use the money for other stuff. :-D

just a side note, about the injectors/pump/return line, all the stuff i'm telling you i just read somewhere else. i havent actually turboed my car(yet anyway)
