Best EMS for Evo 9

[edison_loy]

Dear all sifu,

Wanted to install a EMS to my E9 but duuno which brand should I go for! For light mod only !
Purpose to install cos need stable fuel supply to handle high boost! Correct me if I am wrong! I am newbie too.

Pls advise, possible cheap n reliable

How light is the mod? Anyway emanage is ok for budget buy. Usually people go for haltech, power fc, motec, vipec etc. Anyhow it is important to find the tuner before decide on the ems.

 

[edison_loy]

Light mod mean that all piping mod in and out & fuel pump was done ! Just notice that insuffient fuel supply to increase the boost from standard to higher!advise from foreman /tuner ! I notice after dyno & not satisfy with the result !
Insuffient or unstable fuel supply will damage engine ?It is reason why we need EMS? If yes any suggest for the tuner ? Brand ? Model ? Cheaper ? What are the different and suitable.
Really need help here !!

 

[madiewaters]

why not u just reflash only.U are on light mod ..
so its better to reflash the ecu.

 

[edison_loy]

Which is better ? Reliable ? Cheaper ? Did the cost will be same?
Reason to choose EMS because we paying money at least something we can see compare just reflash ?!
Need your comment ! Pls correct me of I am wrong .

EMS is for highly modded engines. For standard run-of-the-mill IHE mods like yours, reflash is already sufficient. Going for a stand alone is an overkill IMO.

And of course reflash is cheaper than an EMS. With EMS, you also need to factor in the tuner. Bad tuning, bad result, no matter how expensive you bought the EMS.

Some workshop advice to install a piggy back ! Such as haltech pro, E Manage ultimate .Is the piggy back and stand alone are the same ?

 

[pwhyze]

Nope.. different. Stand alone is more extensive in tuning capabilities, it's virtually a new ECU, while a piggy back works together with the OEM ECU. Go for a reflash better, since only light mods.

 

[edison_loy]

How about the cost for both ?
What are the advantage and disadvantage for EMS and reflash ! Just want more detail info !?

 

[greenmivec]

Search in evolutionm.net thousands of posts discussing on it...

Like I said, EMS can change more parameters compared to a mere reflash/piggyback, but to make most of all the variable parameters, you need all the heavy mods like cams, turbo, internal etc2 to make use of it.

Of course you go buy a EMS and fit to a stock engine and get better power, but it'll be minimal compared to the cost incurred. You also won't be using the full EMS feature since there's simply no need for it because the stock ECU can already handle it.

EMS is also more flexible. You can change the tuning yourself if you made additional mods to the engine ( if you learn how la). It depends on your plans really. If you definitely will be modding the engine2 kaw2, go for EMS lah. If not, better stick to reflash.

Cost, definitely EMS pricier. RM 3-5k for basic models? Around that lah..

IF i , i will go for ems.and get the right tuner.then can see the good result and satisfy.if tuner bad.result also we not satisfied.haltech spring 500 ok what rm2950 like that =) if standalone , then no need use air flow sensor already.boleh cabut.i also wanna install haltech to my car.since piggyback cant change my fuel consumption. =)

Bro P3jal,
How can get a good tuner?
Currently people offer me haltech pro cost RM 4800 exclusive tuning.
Any recommended tuner ?

 

[Dayline668]

Even u on 2.3 or bigger turbo the stock ecu still can handle the tuning, even go full open loop(cut airflow sensor) all u need is a good tuner. A opensource reflash won't cost that much.

 

[edison_loy]

How much need pay for the reflash and how frequent need to do reflash ?Did reflash need a good tuner ?

 

[Dayline668]

There is no diff between tuning a standalone n a reflash, all u need is a tuner that knows what he is doing. Your car depend on the ecu to run so stock ecu is the best standalone(Not that u trying to run nos with E85). No need to reflash all the time if u give enough time for the tuner to work with, all u need to do is tell the tuner what do u wan..? what u wan to achieve..? what would satisfy u..? Know what u asking is the 1st thing u need to learn, so u know y u need this to achieve that. Discuss with the tuner, open your mind to his opinion n he will do it perfectly(IF his a good tuner)

 

[edison_loy]

Any recommend tuner ? Or consultant ? Really need learn over this issue ?
FYI, what I need is what is the max output for current mod with proper setting ! As I notice recently an Evo spec state 280 Hp but when go to dyno will not get 280 HP BUT In fact only get 250hp+- . This make me feel surprise !! Please correct me if I am wrong !
Some body can explain why ? And need to reflash or put in piggyback if want to set to higher boost!l for safety purpose right !? Is that correct ?

 

[Dayline668]

In japan they run ron100, so that your diff. Other is temp, drivetrain loss etc...

When u add more boost(air) u need more fuel then the stock A/F ratio to compensate. If not u be running lean n that is not safe for engine.

I do not know any tuner bcos i tune my own car. Maybe other can recommend. Invite some TT with MLOC member sure u can learn more.

 

[edison_loy]

Dayline, Wah, your are tuner, that why to increase the loss HP , need to choice now !
Any comment for the EMS ? Really need advise here?
Need some guide line here!! My purpose is Make sure A/F ratio Is ok and gain HP back to what suppose to be or higher, since fuel pump already change.

Dayline668, have you tuned with grimspeed 3-port before? Do you log AFR & boost in evoscan?
