Boost and ECU update

[buzurk]

hey guys

last service i got done they said they done a ECU update (2008 mps3 gen 1)

It seems i have lost a bit of boost and its agressivemenss

I know 1st n 2nd are limited, but it seems in third i can only pull about 11psi then 4th it winds out to 14.5 ish

sometimes in 4th it wont go over 11 - 12 either depending on rpm and load

is this normal?

There is a suspicion that the Mazda update is more of a detune. Not sure on the reasons behind this or if it is even true but other folks have experienced this too so you're not alone. It could be stress on the stock rear engine mount? Instead of a re-call or simply replacing the mount they might reduce the amount of torque and stress on the mount?

Your solution is probably one of these...HYPERTECH | Max Energy Sport Tune - Get rid of the boost restriction

When was the ECU last updated prior to this problem? There was talk a while ago about an update reducing peoples boost.

Sucks how they can just turn down your boost / power. Not sure how its legal.

Yeah mate that's exactly what they've done. Welcome to the club of very very pissed off people

If you want it "fixed" call Jim at Tunehouse and and tell him you want some ecutek goodness Will only set you back a coulpe of grand....

[buzurk]

So there is nothing that can be done about this ???

Im seriously pissed off hey i lashed out and bought the car purely because of how it went, now i hate it

Hypertech is probably the cheapest fix option. You should tell them "I bought an 3MPS and you've made in into a SP23"
The Hypertech would make a big difference even if you still had the old Mazda flash cause the 3 is limited in the lower gears 'as standard'

pretty much right Rog. But the limiting isnt the problem, it came with that from factory and as far as I can tell that hasnt much changed. Its pulling 4 pound (or in some cases (mine) more like 5 or 6!) of boost from 3rd gear thats a real pain, even 4th still has less than 3rd used to!

The only other work around I've heard of is a guy who tried to buy a new computer without going through a mazda dealer... I dont remember if that worked out or not.

Pulling 5-6 pound from 3rd gear...huh?
