How much boost with the RALLIART SPORT ECU ??

[user1660]

Hi Evo-addicted,

How much boost pressure do you think you can reach with the Sport RALLIART ECU well mapped?? 1.8 bar maybe?? :shock:

Cheers ! :woohoo:

AFAIR the RA ECU is mapped for 1.5 bar.

So thats about the limit.

I wouldn't recommend 1.8!

I'm running 1.5 bar on mine, I was told by a tuner last weekend that 1.6 bar is the limit really. To be honest, you're wasting your time going above this with the standard turbo anyway, you won't get much more power, all you'll do is create more heat. Heat is bad...

Over 1.5 bar and the sports ECU opens the injectors to full!. Stick to 1.5 bar max and you will be fine

bonjour...

im running mine ... @ 1.2 and 1.4 , no point in :cooking: it

I think 1.6 peak is no prob with RA ECU, not with the standard ecu fugly 1.4 is good .......

yes it would be good to see a car 720cc injectors and regulator set up on the dyno with RA ecu to monitor what is going on when boost is increased past 1.55/1.65 :hehe:

This is for the Evo V/VI Sports ECU, the person who obtained the information spoke directly with Ralliart/Extreme at an open day

This would also explain why you dont gain any more power running 1.6 than you do at 1.5 (appart from the indefficiency of the turbo). Running rich loses you power.

If you have other information then share
