Evo ECU into GSR

[crossover]

well guys i've heard that along with injectors and AFM, you can run a gsr engine with the EVO computer.

i was just wondering if there is anyhing else needed? like an EPROM? or some other type of chip?

any info would be a great ammount of help

Evo ecu, 510cc injectors and AFM.. thats all you need..

all bolt on

Yup!

But it will run hell rich considering it will be fueling for a 2L instead of a 1.8L :wink:

I have all them on mine plus a TD05 Big 16G.

My ecu is chipped with a Russ(ozborg) written chip :wink:

PM him for more details

it shouldnt run any richer than the maps since the AFM measures airflow, and fuel is added accordingly :wink:

Around 9:1 in 2nd gear from 20KM/H foot flat to the floor to about 100km/h. intbetween there as boost increases the AF/R steadies between 10:1 and 11:1 @10psi then @6000rpm@15psi its 12:1 all the way to redline. Constant 14.7:1 at idle and cruise.

So off boost fuel economy is crapola. Normal city driving with the occasional spirited drive gets me anywhere between 300-340Kms

Any ideas?

I think i need to take out heaps of fuel in those areas :?

Jett and Turbo_charade are gunna help me out with a bit finer tune.

They know more about it then me :lol:

If you run the 2L (evo) ecu with stock map on the 1.8L it will run pig rich and you will lose power... You may be able to run more boost because its got more fuel up high but you will lose out overall...

I have seen it more than once - the factory maps are hella rich anyways then you go putting it on a smaller engine... They run richer than a WBO2 can sense even before its making boost... ie. <9.5:1 at 2000RPM

If you are gonna bother to put all that crap on your car then get it chipped and tuned properly.

Or even better - don't waste your money and get a real ecu that can be tuned easily... there are options that can cost you less anyways...

drop GSR lancer onto 2L Evolution motor.
Strip the factory 1.8 Alt wires from the starter motor loom all 3.
Remove radiator Add 40cm to all 3 wires sheild and zipp to headlight loom under radiator.

Remove the plastic cover from the manifold sheild.
on the 1.8t engine loom.
Spread the coil and ignighter wires to the evo locations correctly to suit the evo manifold.
Refit the GSr plastic cover and cut the Bend of it.
Make sure all sensors work correctly with the Data logger.
Chip Bay and repair 1.8T ECU correctly.
you would be suprised how amny havent been done correctly.
Go win Races.
At very little cost.

what kind of fuel system do you have? i dont think ur problem is with the Ecu. Do you have a aftermarket fuel pump with stock FPR perhaps?

 

[jett]

LOL do you seriously expect a 2L ecu to run a 1.8L engine properly?

The VE is totally different - even if the airflow is the same the fuel required will be different...

IMO - chip it or you are wasting your time

 

[crossover]

i was expecting it to have to be chipped, i was just wondering who i needed to see about doing that....

and mainly the cost in volved?

I do want to go to the aftermarket option but... i think its going to be more cost efective this way before i have the $1000's to go an aftermarket ecu and tune

 

[VR-4-PLAY]

AUS GSR vs EVO 1 factory maps, load in the Y axis, rpm in the X. (Note the EVO maps have 2 extra load rows)





As u can see the evo maps are actually leaner than the aus spec GSR maps in most of it, especially off boost.

The difference in VE would be alot more important if these were speed density type ECU, but they are not.

ur best bet would be to have the GSR ecu chipped to compensate for the evo inj and AFM if ur keepin the 4G93. Do that and the car will run as smooth as stock. Cost should be round $30-$50 to have the board socketed, and probably $50-$100 for the chip. Not sure who in melbourne is doin em though??

 

[jett]

I know what the maps look like - i've chipped and tuned them all before...

My point was really to crossover that they run pig rich and without tuning them properly you aren't going to gain anything except maybe being able to run more boost...

The off the shelf chip tunes aren't going to gain you too much either - for a noticeable gain you need to put an AFR on your car and tune the thing for your engine setup...

The safety margin that has to go into the generic tunes to stop idiots blowing up thier engines means that you lose significant amounts of power because its so damn rich...

 

[VR-4-PLAY]

i agree the best way is to tune with a WB02 to get the best tune for ur exact setup.

My point is that u are not goin to run richer than stock if u change the ECU and injectors and AFM. That said the factory maps are very rich up top, and assuming u keep a close eye on ur AFR's, then there are plenty of gains to be had leaning it out.

I guess it depends on everyones induvidual setup. This discussion (Chip vs AEM) has been had a hundred times before, and generally the end result is:

Stock motor with slightly larger turbo, IC, injectors etc = Chipped ECU
Built Motor, BFO turbo, Cams = Aftermarket Engine Management.

Keep in mind not everyone is doin an 8k+ build and they dot need to waste money on an AEM. Plus with an AEM u need a retune any time u do a mod and change the VE of ur engine :wink:

Not trying to argue with you jett, just sharing my experience (as u are too) .

 

[jett]

Yeah ok - run richer than stock being the operative there... I agree with that. The main point is really that you aren't going to gain anything without tuning it...

Its also important to know that there are AEM options around for similar costs to buying the evo1-3 setup..

Ie. Evo ecu
Injectors
MAF
Bay and chip
Chip tune...
Those things could easily cost you well upwards of $500 plus to get it tuned right you need a new chip every time...

I have just installed an adaptronic on a VR4 for around that including installation, and a base tune to 20psi...

If people are interested I can make up adapter looms for VR4/EVO/GSR and organise very good prices on the adaptronic unit. Plus provide a base tune...

If you have that gear already or can get it on the cheap then a chip is probably a good option - I just hate to see people spending ridiculous amounts of money on an evo ecu setup for no gain (or negative gain)

 

[crossover]

the other mods im looking at doing around the same time are, td05 14b, 2 1/2 or 3" exhaust, AVCR, fmic, injectors, afm, throttlebody,

i already have a walbro, and i am also thinking about a FPR aswell.

so now im thinking am i better off with the EVO ecu chipped or the GSR ecu chipped? as i have both ecu's sitting here currently.

 

[VR-4-PLAY]

evo ecu, as it has the more load rows on the maps (run more boost before you run of the top of the map)

 

[crossover]

awesome, does anyone know where i can get this done in melbourne?

 

[Richard]

A lot of guys may think this is a waste of money but OH WELL. lets say if I wanted to keep my 4G93 motor on the outside only, that is bore it out and spend a fortune on a custom one off stroker crank, some strong conrods and forged pistons so it would work out about 2.2 litre or so, then polish and port the head & manifolds then whack on a big turbo & intercooler can I then use Evo ECU, AFM and upgraded injectors and it will work good?

The cylinder walls of the 4G93 block won't take much more than 1993cc (or so), you'd never get 2.2L mate :wink:
