after using em-blue... i regret for not saving more...:hmmmm:
otherwise Haltech S500 for me...
how your car,any noticable ecu learning back?

Hmm, i'm going to help by highlighting a few things about this ECU. Got the facts from Haltech web, via
Haltech – Engine Management Systems
The tuning method available kinda basic. It's
Load sensing by throttle position
or manifold pressure (MAP)
ECU programmable output is only 2. For my usage when you go start to go further, it isn't enough. Especially when you start to control everything via ECU.
Well, for this price it should be enough since this is one of the entry offering from Haltech. Not to say it won't chunk out power, put in the hand of cuscostructbrace this is a magic.
My humble opinion, 20v with or without the VVT works very well when it is tune via TPS and MAP. If either or only, it isn't that smooth. However, top end power remain the same either way.
100% tuner dependent, really! Don't forget to dial your cam pulley before you tune. Have fun ..
Chew...you are right,sprint 500 is entry level ecu from Haltech,it is meant to be a cheap stand alone for people who doesnt require much input and outputs.
For 4 cylinder engine,it can control 4 injectior sequentially and 4 individual coils(COPS).It has 2 fixed output (tacho and radiator fan) and 2 general purpose output(GPO).On the input it has fixed speed input,o2 sensor and aux rev limiter(for launch control).
Lets take example for 4AG (16v/20v) for street use;
Injector and coils not a problem,can control 4 injector and coils.On the GPO.one of the 2 GPO is fot VVT and the other one can be used to control anything you want(ie:idle up).
Basically there is everything you need,but for true engine management solution for street use,we need more input and outputs for a/c,electrical load,better idle control when loads come on and off,and even worse if sprint 500 used on turbo vehicle whereby we want to control the boost solenoid using the ecu,the I/O is not enough.
For that there is the sport1000,which is more expensive.For me,if the car is for track use,sprint 500 is good enough,depends on the degree of auxilary stuff we want to control.For street use also not a problem,but have to sacrifice on the a/c control,which is not a problem as we can run the a/c separately,just that the refinement not as good as stock.
Power wise,it is in the hand of the tuner,but surely it will be better than stock,and no case of 'ecu learns back'
About the load sensing method for new haltech series,you can control the fuel using TPS with MAP correction.
