it is a 100% plug and play, just plug it in and drive it. yes you can use it with 96 since it is a factory ecu it will retard the timing depeding on octane.

 

I would not rely on the ECU to retard the timing as sometimes it may not be enough to save a motor.

Why spend money on a part that won't even work optimally in your car? You're better off getting your ECU reflashed, or a UTEC/AEM setup if you want something programmable.

 

Pal, please do not comment if you dont know the facts, this ecu was developed by Ralliart specially for the Evo7 which is the case of the guy that made the post and myself, they do not make it for the evo8, just evo7, I had it for 3 months before the AEM and it works very very good, it is very well known in europe for the evo 5 and 6 also. For the money, you can not buy a better ecu than that one.

I ran my car with 272/272, stock turbo, Ralliart Ecu all day long at 1.6 bar and the car ran 100% better than the standard ECU, just remember, there is a big difference between the map that comes with an Evo 7 compare to the Evo8.

 

You need to remember that the guys doing this are not in the US, so the flash isn't an option. Also, this is a Ralli Art item and is probably at least equal to and more than likely better than the other options you listed.

 

Dude, a 100 octane map is not going to work well, and perhaps not safely, with 96 octane gas. How hard is it to understand that? You're right, I don't know anything about the mapping of this Ralliart ECU. But you yourself said it was developed for 1.6 bar of boost and 100 octane gas. Why don't you define "very very good"? You don't have any experience with this ECU on 96 octane gas either so your comments are just as worthless as mine then.

And frankly, the way you give advice scares me. You're telling him to just put the ECU in and turn up the boost. That's just not very smart IMO. I've seen people blow up motors even with the ECU retarding timing. I'm just trying to give the guy something to think about to help him play it safe.

When you start messing with the fuel control of any car, it's best to have some sort of datalogger to monitor the knock activity, EGT gauge, and wideband. Also check your plugs often during tuning sessions. Sometimes the knock sensor doesn't pick up real knock.

 

Crazy4cars and marksae thank you for inform me. First, I'm using a high octane gasoline 104RON. Second I will not turn my boost up because I will contact Ralliart Japan first and ask them if they approve it and how to. My car is a JDM Evolution 7 and I don't know a Ralliart ECU for the Evo 8. I can't do a reflash because I don't know anybody where I live that have the knowledge necessary to work on my Evo, so the best way to change the ecu parameters is to trust on Ralliart company. This ECU changes the ar/fuel ratio, the timing, raise the rpm limiter, raise the boost limit, change the waste gate operation, change the fan operation, with just this ECU alone you can raise your power by 20hp and the torque at least 14flbs.

 

this sounds good! There's no mechanic here also in my area that knows how to work on my evo. I have the only EVO 7 here. There's 1 evo 3. thats about it.

With my mods, can I just plug in this ECU? And expect some HP gain? Not dangerous?

 

This ECU is "plug and play" not dangerous because it was developed by Ralliart. This ECU can give you 20-25hp and 2-3kgfm of torque. I would suggest you to put a Ralliart 1.3kg radiator cap or similar, Ralliart 71ºC Thermostat and Samco silicone radiator hose.
I think that Tomei and Mines have performance ECU for the EVO 7, but I can't say if they are good and safe.

 

This sounds too tempting!!!! I need more feedback from ralliart ecu owners.....just wanna make sure nothing blows up!
25hp gain on just the ECU w/out any tuning??? damn!! that good enough for me!

 

Hello guys
I bought an used ralliart sport ECU RA560649R1 for my evo VII and I don’t know the options of this ECU
Some body have experience on this ecu
please inform me if there is an antilag system on this ecu and is necessery to cut or remove some wire and what the fuel octan number its necessery to use with it ...
