Max boost
 

Just wondering what the max boost you can run on a standard ecu is? Car is a uk Blobeye wrx/sti.

Pretty much whatever you want. Im on the standard ecu and running 1.5 bar.

Remapped? Boost limit will have been raised by mapper.

Yeah, mapped by bob rawle.

I would have thought if you're running 1.5bar then Bob will have set your limit to around 1.6 or 1.65 bar

Stock won't be unlimited boost,would think stock limit will be around 1.35bar that's what my v3 sti was.

a newage map sensor sees 1.7 bar so not unlimited.

Put a Perrin 4bar map sensor on mine and have raised the boost to 1.75bar , standard ecu , also mapped by Bob Rawle

around 1.6 or so is as much as you'd want to go on the standard map sensor - as has been said above a new map sensor is needed after that but you'll still have difficulty targeting over 24psi in some ECU's.

You would be looking at aftermarket boost control systems after that and you can still keep the stock ECU doing fuelling and timing without any hassles.

I'm running 1.7 peak, holding 1.5 to limiter. I asked for the boost cut to be removed during mapping (std 255kpa map sensor doesn't read high enough for me)
