Max boost the ECU can control is determined by the range of the boost sensor and the sensor's transfer curve in the map. So providing the right hardware is in place the software can control any level of boost.

iirc the ecu can see 1.7 absolute max, however above that its blind and not in a good place for safety. the limit is the ecu not the mapping software
If your going above that than really aftermarket is the way to go.

Define safely? removes boost cut and fuel cut so if the boost spikes the ecu wont see it and back it off which prob means bye bye engine.

Are you sure about that ??
On ecutek with JDM sensor i think those systems are still in place upto 1.7 bar,
Then on carberry you can set the limit at which fuel cuts due to boost ?
Xluben Fogturbo runs stock ecu around 800bhp flex fuel e85,
Sure syvecs is the daddy but don't underestimate the stock ecu if it has the additional hardware needed
If i am wrong then please correct me but only going from what i've seen and read

As i says, on stock ecutek with JDM sensor scaled it can now see whatever that sensors limit is. dnt quote me but i think now 1.9*
With carberry it can see whatever you tell it to as long as all sensors are capable ?
Why wouldnt it ??

I've never looked into it in that depth, but i can ask pat the exact ins and outs on sat if i go up.

Well using your ruler as an example,
Stock ruler/ecu can read 300mm/psi max
You scale Map sensor so that 1 mm/psi is actually 0.5 mm/psi (For example)
Your 300mm ruler is now good for 600mm in theory,
I understand all stock sensors have limits but if sensors changed and mapped to suit i though sky was the limit,
You have seen that xluben fogturbo bugey ?? thats on stock ecu with carberry.

As the guy says above define safe.
Running that boost on any stock engine is pretty much russian roulette.
Also depends what turbo and loads of other things fuelling,mapping, and how much abuse u give it.
But theres always the chance that it can overboost and lift your heads as ur now overboosting from 1.7.
Where as normally if u overboost from ur 1.5 ur still safe. (Relativly Speaking)

I thought newage sti's are good for 400 to 420bhp so you can up the boost a little safely,, that's why I asked if with a 4 bar map sensor and a ecutek remap would be safe to run a little over 1.55 of boost??

20g can too if built correctly or generous dyno or meth too
a real 400 bhp turbo should crack that with 1.55 bar
ie sc42 md321 etc.
Even a cheaper mamba gt30 would.
what you planning on running at those levels ?

most folk running that power do so with big gt30 based turbos and or meth

I'm at 380bhp at the moment on a v7 JDM sti with a sc42bb Turbo, perrin intake, inner wing induction kit, 7's, walbro 255, full 3" turbo back de-cat exhaust, sti tmic,, I've got a process west tmic and RCM headers with Harvey up pipe to fit before map,,, just didn't no if I'd need to up the boost??
Id imagine the better top mount along with the headers should see you past 400 then you can up the boost if your happy
