Hi guys

Just a quickie......what's the max boost Ecutek can safely control?, is it 1.5 bar?

I think they can do 1.5.5-1.6

IIRC ecu handles fine at 1.55 bar but 1.6 as stated above is the max,

I've been running 1.55 bar for 3-4 years no problem with ecutek

Excellent, as I thought. Currently running approx. 360bhp at 1.3 bar so room for a bit of a power hike I think

I already have 20g, FMIC, larger injectors so opinions whether i'd top 400bhp at 1.5 bar?

Steve's Sti

I'd hazard a guess maybe 380 to 390 depends on setup

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.

depends on the ecu standard don't like past 1.55 as in it wont handle it safely

DT-SPD

It will if the sensor and transfer curve are correct in the software/map. The ECU only see's a voltage from the sensor and translates that to a pressure via the transfer curve.

Sorry to drag up an good thread,, is it possible to run more boost then 1.55 bar on a newage ecutek remap with a 4 bar map sensor??

Tidgy

It can only see what it can see, so if you push it to the limit you have no head room for adding in cut points as protection or the engine (fuel cut, boost cut).

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.

I was told to fit a JDM Spec C map sensor as this could be scaled and would allow a max of 1.7 bar,

Tidgy

read my post above

SmurfyBhoy

Yea it wasn't really a yes or no eh ?

As far as i was told that usuing the sensor from JDM cars can run 1.7 "safely"

To do with scaling the sensor i believe, so still allowed those cut points as ecu is now reading an offset



Then there is Carberry.......

Tidgy

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.

SmurfyBhoy

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

Tidgy

Can set it to 6 bar if you want, but if it can't see it how can it act on it?

SmurfyBhoy

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 ??

Tidgy

I would guess its an upper limit on what the ecu you can interpret. Bit like a ruler, you can go off the end of it, but you can only measure to the end.

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.

SmurfyBhoy

I'm sure it's all about scaling

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.

Bob Rawle advised me to get a 4 bar map sensor (Perrin) so we could set my boost to 1.7bar safely

RAGGY DOO

Yup on mine too dom 1.7 bar using Perrin 4 bar map sensor

TIZERBOY

iTrader: (1)

I've been told the same get a perrin 4 bar map sensor and you can up the boost a little,,, is this safe though???

SmurfyBhoy

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??

domino46

My engine isn't stock and have been running this setup for a while without any issues @ over 500bhp

SmurfyBhoy

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

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 ?

SmurfyBhoy

which setup is that bud ?

stock ecu ? Boost ?

ecutek or carberry

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??

SmurfyBhoy

have a look throught the thread about most power on stock internals.

Id imagine the better top mount along with the headers should see you past 400 then you can up the boost if your happy

Thanks for info SmurfyBhoy.....
