thats great do keep us posted on the developements.
now coming to pros and cons.
box is plug and play after a couple of instalations , its a DIY thing.
but boost controller is a different ball game

box is adaptive[ hence different boxes for different cars. and not only that UIS and CRDi engines have different boxes.] while the boost controller is not.
its got only to do with the turbo.[ what is done is. increased turbo boost is set and accordingly a bypass[ generated by ECU itself with new inputs..actually only the air input is changed and ECU designs the injections accordingly..this also involves injection window to be made larger] injection map will be run by the ECU with the new Boost pressure settings].
ground level is that a simple PWM signal is what actually controls the solenoid valves in the waste gate.
the frequency of the PWM signal to the solenoid valve is hiked up to get the desired level of boost.[ bear in mind that the solenoid valves are binary devices] there is a physical limit for which the they can oprate!.
in reality we are sending false signals to wastegate to open at a higher than stock PSi level.][ but the beuty of this boost controller is its accuracy and its greater compatibility]
IN A BOX SIMPLY PUT A HIGHER RPS output causes the ecu to prolong the injection window. and a bypass map for this is required which will be present in the box!
but keep in mind that the INJECTOR + PUMPS and EMS has a tolerance limit . so leave the insane boost levels because the other non-engine parts will go for a toss. read the transmission!! in boost controllers there is no need of bypass maps.
they send the false signal to ECU also which adjusts to the higher intake.
the boost controller is a real time system it can be switched on and off. whereas box is always on or off[ when removed obviously..haha] and that is one disadvantage.
coming to the Box- it has giot a fail safe mechanism. simply put .if something goes wrong the ECU will be handed over full charge and the Box will Shut itself off..hehe .
so thats why the BOX people give warranty on box and gurantee on engine life.
but the boost controllers are having no gurantee[ and read no fail safe mechanism .you go wrong ..then you are gone..hehe] its got more to do with the tuners intention. you set the Psi so you are the boss. simple.
and yes the gain in Boost controllers is MORE than in a BOX.
a simple math is like this the stock Psi is 7. the solenoid valve controlling the waste gate can be made to oprate even at 15Psi using a Electronic Boost Controller.
but in reality the stock waste gate of an elantra can handle 12Psi as stock. as in international markets but in INDIA read cost cutting....INTERCOOLER! they set is as 8-9Psi stock . but then even 20-22PSI is possible but only with intercooler upgrade and other upgardes.[ read clutch, custom mapping. with better injection torque curves. a flat out torque in mid - higher end of engine RPM]
and by the way why only GReddy what about Apex-i and Gizmmo electronics. they also make good boost controllers ..i have no idea of indian dealers and installers though.
but i suggest to wait for as long as an official dealer and installer is available for this type of mods.
the safer bet for a novice would be a box.
but the box will CAUSE SMOKE!! .where as the boostcontrollers will be better off as the ECU tries its level best[ depends on the effeciency of the algorithm ] to do exhaust treatement within the exhaust system tolerance limits. instead of ingoring the exhaust treatment for the addtional window period..hehe.
cost wise the boost controller and Box are both around the same.
but the VGT engines .poor fellows like me. the boost controllers are of no use to us. VGT is a no-no when it comes to Boost controllers coz simply..ONLY ECU can vary the boost of the VGT which it does beutifully.
for VGT fellows like me. the BOX is the ONLY way or a complete RE-MAP.
got lots of work to do..i am out of this place.
peace out
