I've been told im limited to 1.5 bar boost by my stock 2003 sti MAP sensor, on ECUTek

To run 1.6/1.7 bar, what other stock subaru MAP sensor can i fit ?

Am i right that a Hawkeye Sti one will do me ?
or is it only the JDM Spec C ??

 

I think it's all down to your ecu that limits boost 1.55 bar. An after market ecu will eliminate that.
Ecutek still uses the stock ecu, it's just a file put on to it.
Afaik.

 

yip i ended up going syvecs as was on my boost limit of 1.5bar

 

You're correct the uk map sensor only reads just over 1.5bar, any jdm map sensor will read up to 1.7 bar. Beyond that you will need an aftermarket 3 bar map sensor, it has nothing to do with ecu board itself.

 

What bout a hawkeye one ?
Only if its jdm ??
Yes 1.7 is all im after.

 

my 2005 jdm struggled to control boost on the standard ecu with the 3 bar at anything over 1.5 was not accurate simon wanted to fit a boost controller i was not happy the have boost controlled by one so opted for a syvecs

 

I used an AVCR when i was on a standard ecu and map sensor to get to 1.7bar.

 

Boost control itself is completely separate and I agree an aftermarket ecu or even an avcr are much better than the standard ecu

 

My 97 UK Turbo comes with a 1.7bar sensor as standard too.

 

Can anyone answer if the uk hawkeye sti and jdm hawkeye sti are they same sensor i may have got the wrong one

 

Not sure about the UK cars, can only answer for the JDM's. You would need to ask a mapper who has mapped a UK hawk

 

Thanks mate
Youve read my problem.
Just dont want to have bought something thats no use to me.
If its pretty much the same as the one in my blobeye.
Will try source a jdm one just incase.

 

I don't see why a UK and JDM map sensor would be any different,both should read up to 1.7bar. Standard boost on a JDM is nowhere near 1.7bar so there would be no need to fit a higher rated one.
If you are aiming for 1.7bar then you will be right on the limit of boost/fuel cut,so if you want 1.7bar the get an aftermarket 3bar map sensor which will read up to 2bar.

 

Here's a link to a nice cheap and easy mod if you can use a soldering iron.

I have a 4 bar one here but it need soldering. And i do t have the scaling and offset data for the mapper.
Mapper would prefer me to get a spec c.

My problem is i have got a hawkeye one because i thot it was the same.
Didnt realise he ment spec c

Does anyone know for certain if the are different ??
