Do you have any experience with Ralliart ECU for E7?
I need to know what power I should acchieve with above.

 

I'm also interested, I was thinking of a Ralliart ECU upgrade+ electronic boost controller and a new clutch (the stock one is not very good)... I would say maybe 320-325hp with these upgrades

 

don't have a ralliart ecu, but have a mines on a tme. not too bad, lets you boost up to 1.3-1.4bar fine.

you definitely need a new clutch with 320-330bhp. twin-plates are good

 

After installing Ralliart Ecu in Evo 7, engine start for only 2-3 seconds,it seems to me that fuel pump doesn't work.
When we're using original one all is ok.

 

Tommy,

check if you connected it right. if I am not wrong, it is pretty much "plug-and-play" (if its like the mines). If it is hooked-up corretly and it still doesn't work, then the ecu is broken and you need to get a replacement.

are you doing this yourself or is a tuner doing it?

 

It's easy to install but doesn't work.
This ECU is from Ralliart Japan ,maybe for LHD cars must be different ?

 

sounds like you got a faulty one. Can't think why RHD/LHD should matter

 

Hi, just ordered one myself (Ralliart ECU for Domestic Rally). Waiting for it to arrive end of the month...can you let me know the performance of your ralliart ECU? I don't know if I made the right choice or not.

 

If you haver ordered a rally Ralliart ECU you have made the wrong choice, because it's mapped to use an air intake restrictor (32mm i the case of Gr.N).

 

So which model should I get?

 

Ralliart sells an ECU called 'Sports ECU' mapped for road use.

With this ECU you can run more boost without risk of fuel cut or running lean.

Any Ralliart should be able to source one.

You should note that if you are driving a LHD car you will lose the immobiliser feature if you fir this ECU.

 

Damn! Wrong choice. Thanks for the info guys. I hope I can still cancel the order.

 

RS-2 TME: Tried asking the SPORTS ECU. Just waiting for their reply. Thanks for the info.

ChrisEVO: Maybe you can ask in your country if they have the SPORTS ECU.

Tommy: Looks like we made the wrong choice

My 2nd choice hopefully won't have compatibility problems: A'PEXi POWER FC. What do you guys think of the performance of this one?

 

I have spoken with a Ralliart manager and he confirmed that the "ECU for Domestic Rally" Edition can't be used for all LHD Evo7s that have been exported from Japan.

Let us follow RS-2 TME's advice in getting the SPORTS ECU instead.
