ECU remapping recommendation

[PNGMK]

I had a problem with the CEL in my FXT2.5.....

the dealer wanted $2000 plus to fix.

A local tuner removed the cold weather emission part that was tripping the CEL and remapped the ECU to stop the CEL alarm and tuned the car..... My FXT is now good for 293HP and 511Nm. That's 40hp more and 100Nm more - with all stock engine parts.... and LTA friendly.

PM me if you need his name.

The increase in torque is impressive but I suppose you are on the edge of what is possible with stock parts.

The 2.5L is a good block, though, but I'm still stuck with the older 2.0L

MI locally are not worth what they charge and so long as the car is out of warranty there are several good tuners and mechanics to take over.

The stock wastegate can't hold more than 1Bar for long (~14.7 PSI). That's the major limitation. Once you get into the >320HP apparently the stock fuel pump can't keep up (nor the fuel rails). You replace those and then at 350HP apparently the injectors run out of duty cycle.... it's a never ending chase so I'm quite happy to leave it all stock and "LTA friendly". The real issue here though is that you can't legally upgrade the entire exhaust and it needs a high flo cat to really fly.

Ah, I feel like a teenager again dumping my paycheck every week into tuning my old Mitsubishi Rock solid engine, just everything else around it was shit. I've done all of this. High-flow turbo-back exhaust, larger turbo, injectors, Apexi fuel computer I could tune on the fly, large front-mount intercooler, etc.

All perfectly accurate.

I limited my previous Legacy, in Malaysia, to ~310bhp but had all the work done here in AMK.

My exhaust was definitely not LTA approved.

ooooh performance upgrading that takes me back. Even keeping the car stock, having a remap (if done well) is worthwhile. I always appreciated the difference in throttle response and the lack of flat spots as much as any torque or bhp increase.

I did have air intake / remap / cat and exhaust done on a BMW 325i and that really flew afterwards. Did remap only on a stock Audi 2.7 bi turbo and that was like a rocket afterwards too, the last car I had before coming to Singapore.

Memories...........................now I have the MRT

The stock maps are very conservative and assume low octane crap fuel and are very cautious on the fuel mix, timing and boost.

I explicitly stated I wanted it remapped for 97RON and had a tank of 97RON in when it went for the Dyno.

I'm 49 and all my previous tuning has been with carbs so I've learnt a fair bit along the way.

I've got a set of springs sitting her for the wastegate to help with waste gate creep.

So out of interest do you follow up with anything else after the upgrades i.e. changing oil type and oil change frequency etc. I went to Mobil 1 fully synthetic and changes every 6 thousand miles, might have been overkill. It was certainly expensive!

I've always changed at 10,000 km and usually use some sort of synthetic.

I intend on renewing the COE on the FXT2.5 - there will be so few of the turbo ones around in 12 years...

I remapped my 1.25 fiesta mk6
Got serious speed about 90bhp

Really? I think the original spec is 82bhp so you gained 8 and got 'serious speed'?

Maybe it was the go faster stripes that really added all the speed

[PNGMK]

Now to remap the Duke 390...

[Pal]

Surprising lots of car enthusiast here!

Most expats I have met care less about their cars let alone modding ...

Cool

When most are stuck driving a Santa Fe, an Odyssey or a Vios because of the extortionate costs compared to what we know a car costs, it takes a special breed to buy something a little unusual or special and then spend a little time and effort on it

Little time only, though
