2G does ecu tuning increase performance?

[vince232]

hi good day guys i just installed a 4g63t from i think from an eagle talon (dont know the difference to eclipse)
and i somewhat feel the engine is so much weak from my stock 63t with a mines ecu from an evo 1. i cant even feel the boost with the eclipse engine. anyway can a simple retuning of the ecu increase performance? i think my ecu is e2t37876. do i need to buy a new ecu for tuning ?

 

[jery1234]

There's no difference between eagle- eclipse engine so it should perform the same .

The ECU plays a huge part in overall performance. If you were running your last engine on an ECU with an aftermarket tune and then you installed this one with a stock ECU it is likely you would see a loss in performance.

But your post is not complete enough for a real solid answer, did you install just a short block, a long block, did you also swap turbos? Also what are the numbers on this new motor from a compression test? What other modifications are done to the car?

 

[vince232]

i have an all stock evo 1 engine except mines ecu installed in a lancer.
i also have an all stock 2g eclipse engine with stock ecu installed in another lancer.

i still dont have a lot of knowledge about engines and i know that evo engines are stronger than 2g's stock so im already kinda expecting a lesser performance.
however im disappointed with the 4g63t from eclipse. i dont even feel the boost kicking in unlike from my evo 1 engine.
so im thinking if a tune can make it perform a lot better since my evo 1 is stock except the ecu.

The evo 1/2/3 7 bolt block is no stronger than any 2g 7 bolt block, you could argue the split thrust 97-99 blocks are stronger than the evo blocks due to design. You'll need to provide accurate build details to compare engines and turbo setups between cars.

hmm i have read that stock evo 1 engines are 250hp while 2g eclipse are 210.
well one thing is for sure though i have a td05 on my evo engine and td04 on my eclipse engine

Keep in mind the EVOS had a different tune from factory so it will be more aggressive, the EVO 3 also had 9:1 compression,

The split thrust is a better design engine and the EVOS never saw any if this untill the rotated wide block .

A bigger turbo running more boost doesn't make an engine stronger, it just makes more horsepower.

yep that was what i was thinking. maybe my stock ecu from the eclipse are just tuned for daily driving. it still has a 6k rpm limit.
do you think having the ecu tuned aggressively will help the performance stronger? or do i need to change turbos then have it retuned?

 

[emeracing]

The td04 I belive is a 1gen eclipse turbo.

 

[vince232]

A bigger turbo running more boost doesn't make an engine stronger, it just makes more horsepower.

hmm i see. so what should i do for better 0-60 and more feel of "pushing my back to the seat" when the turbo kicks in?

 

[donniekak]

A bigger turbo, more boost, and a fuel system/tuning upgrade.

Strength refers to how much power can be made with an engine before it fails.

ohhh i see sorry for the wrong terms i used im still new to this haha thanks a lot
well basically now with a td04 i just dont feel any of that pushing my back to the seat feeling when turbo starts to kick in.
can a tune change that? my ecu as i said is an e2t37876 can i have it tuned with stock ecu i have?
or i should get a bigger turbo first?

First off I'd suggest measuring your actual boost levels, so if you don't have one, grab a cheap boost meter and hook it up at the line from Intake Mani to Fuel pressure Regulator. That TD04 turbo should be a 13G if I'm not mistaken, which could mean you have a 1G Eclipse/Talon engine (so 6 bolt). Stock pressures on that turbo is about 11 psi. Check with a boost gauge how much you're getting.

 

[XiholdtrueX]

Second that you want to know more about your engine as a whole especially how much psi is being produced, for all you know you could have a boost leak or blown hg there could be a number of things. A ecu tune will improve upon only how well your engine and its complimentary components are running. ie turbo,fuel system, engine itself

oh thanks. any physical check up i can do to know if it is 1g or 2g?

 

[Kryndon]

Umm, this car is neither a 1G nor a 2G Eclipse/Talon. HOWEVER, judging from the cylinder head, I would say it's a 7 bolt block, as it has the identification notch on the left side of that little rectangular block next to the mount point.

Wait, is this already put into another car? I'm getting confused here.

Also you can check the number on the transmission case (should be visible underneath the intake manifold), and also the engine code itself, but that is under the exhaust manifold behind the turbo.

Yep we bought a galant with a 63t and they say the 63t is from an eclipse. But now we installed it in a lancer. So now im trying to figure out if it is really from an eclipse and which eclipse and how can i increase hp and torque.

So far it has a td04 turbo
And ecu code is
e2t37876

 

[Kryndon]

Ok, now it makes more sense. So you possibly bought the Galant VR4 (1989-1992) with the 6 bolt 4G63. However, the head on yours is clearly from a 7 bolt based on the notch I was talking about. It is possible that it was swapped at some point, though.

Really all you need to do is check the turbo code/number, and the engine code. Post them back here and I'm sure we can find out exactly what engine that is.

 

[XiholdtrueX]

Is the rest of your car stock? There are various way to increase hp, up the boost, get a safe tune, better breathing ic but you have to make sure it is running correctly and has all the basic maintenance before messing something up

Cant see the engine code. didnt buy a vr4 89-92. i bought a 7g galant i think it's original engine is a 4g63 sohc. but the owner said he installed a 4g63t from an eclipse which is what you can see in the pictures on the next post. ( if it is really from an eclipse).

From my understanding 7g galants came with a 4g64 sohc, i have one in my drive way maybe he did a head swap and thats what you have. Would make sense its a common swap. 4g64t

 

[Terrj]

Possibly a common head swap. Why would anyone do that to a galant though ...

 

[FIBA M - EC17PSE]

Well looking at that head and the water outlet the engine is from a galant vr4 possibly US spec as it comes out at the side and the pipe curves around your bypass pipe but in stock form it's ment to be like that for the big turbo intake stock rubber pipe.

So my guess is it's what ever spec came with the galant vr4 in the US, the valve cover is also red which does indicate a vr4 engine from factory, although it can be changed if course the water outlet is very less likely to be altered. So I'm 100℅ saying search specs on the vr4 and what ever that has stock including turbo is what you most likely have
