Problems With 4G93 Eterna

[johndilla]

Hi to all the sifu out there,
I hope that i could get some help from you guy, I am driving a rojak transplanted 4G93 eterna engine which the transmission had been converted from automatic to manual and are using MMC 6123 ECU.

Here my problem:cry_smile: ,

1) After driving long distance or driving about 3-4kRPM (with air-cond turned on), the engine RPM will drop below 1kRPM and eventually turn off when it is idle. I had consulted many mechanics which suggested changing of the throttle body which I had done twice already and the problems still persist. Any idea whether it is due to the ECU?

2) Once when I had push the car to the limits (above 6kRPM) there where smokes from my spedo and it had affected the electronics (Head Lamps and signal light) to be not working. I had sent in for repair at an accessories shop and they had recommended that i redo the wiring for the engine(previously wiring had been coverted to fit a 4G91 dash). Is this necessary? They also told that it is due to the alternate current wires which had been jumble up 2gether which had cause this also.

I would like to thank you in advance for helping.

4G93 Eterna ?? Pardon me but my understanding Eterna isn't it V6 or 6A1x ?

1. Have you check your Mass Air Flow (MAF) AIR FLOW SENSORS? Errr...6123 ECU original is from what engine ? What's the original MAF code and the current one that you are using ? Engine die off or bad idling on MMC engine most of the time related to incorrect airflow or intake setting

2. Oh mine...smoke from speedmeter ?? You have a volt meter in your dash ?? Sound like somewhere is overcharged...

this is interesting... 4g9 series can rojak with a 6a10/6a12

can u tell me more about the engine.. how do u hybrid it..

hello bro i have the same problem wit u,but how is your fuel comsumption 4 yours??i fuel in rm50 but just can go for 120km only....it is so high for tis i'm so confusing wit tis ecu 6123??plz send me your contact no to me to disscuss,ok?

 

[keith_njt]

very high fuel comsumption 4 ecu 6123

there are eterna's that comes with 4G93 SOHC.

1.8 or 2.0 ?
v6 or 4 cylinder ?

1.8 or 2.0 ?
v6 or 4 cylinder ?

4G93 is 1.8 Inline 4

i have personally seen 4G93 eterna halfcut. and a few of my friends are using them. based on their research, 4g93 eterna has gear ratios suited for highway top speed runs, and their engines has more torque compared to other 93s.

they use 4G93 1.8 twincam engines.

anyway john, please have your speed sensor wire checked. easiest way, check out your digital speed meter speed reading (RSM/hks type1 timer etc etc). if no reading but speedmeter in instrumentation cluster working, that means speed sensor kong. must change speedometer..

i suspect that is the cause of problems. improper wiring job will also cause this...

 

[rajie]

is this the GRS timing belt is different side compare to the other 4G93t ?
the timing belt is like evo 4,5,6 ?

u have tuned up ur car back

u have to rewire back cause the 4G93 uses a lot of grounding just did mine..my ignition switch was burnt n rewire the car back....

about this halfcut
this is not the first one
even my sifu also saig this half cut got problem
n even no power...
some of my frenz even chamge the entire wiring to the gsr 4g93
i also dunno what the different

 

[boyzone]

Do u mean that with Eterna chasis JDM 4G93 is not so powerfull??
For air con problem, I think u need to recalibrate with ur idling with ISC stepper motor. And of coz, u need to check back ur wiring... seem like some wire is wrong connection or over load.
At our side, we have a lot of this version of 4G93 on the road... and most of them are damn powerful...:X-:
Hope can help.

 

[boyzone]

BTW, what is ur air flow code number??

The timing belt is still on the same side for as the evo 1,2,3..

Even 6a12 & 6a12TT timimg belt is still on the same side unlike the CK models

This engine come from eterna visage touring e52a year 94/95/96.This is the spec
ENGINE
Displacement, cc 1834
Engine model 4G93
Max.power (Net), kw(PS)/rpm 140 ps (102.97 kw) / 6500 rpm
Max.torque(Net), N*m(kg*m)/rpm 17.0 kg*m (166.71 N*m) / 5000 rpm
Power density 8.5
Engine type Serial 4 cylinder DOHC16 valve
Engine information
Fuel system ECI-MULTI (electrically controlled gasoline injection)
Turbocharger No
Fuel type Unleaded regular gasoline
LEV system (Low emission vehicle) No
Compression ratio 9.5
Bore, mm 81
Stroke, mm 89
Final gear ratio
Fuel consumption at 10-15 modes, l/100km 7.3
Fuel consumption at 60 km/h, l/100km

--------------------------------------------------------------------------------------------------------------
If your fuel consumption not correct like the spec above,retune your car adjust the TPS and realigned the distributor.I am also using this engine in my satria.full tank 40 L (rm80) cruising 110kmh-130kmh can go around 450 km.This engine good for top end but little bit slow response due to gearbox ratio,wiring and ecu.If u want better power (fast response/pick up),change to gti/putra wiring and ecu.The compression ratio also different with 4g93p.To get more pickup,can change to high compression piston like mivec piston.The satria body wiring and engine is different so need to "rojak".Some unexperienced foreman cannot do it very well.Since 1 year i am using this engine,no prob at all.my engine idling is good either on or off the aircond.For ppl have the problem with this engine,can pm me for discussion.

 

[malyadayada]

gtpui pernah dyno?

 

[GTpuI]

sory not dyno yet.I get the information from net surfing.Are u using the same engine malyadayada?From my experience,1st gear reach 55kmh 6.5krpm,2nd 95kmh 7krpm,3rd gear 140kmh 7k rpm,4th gear not try yet..this is the gear ratio:
1-3.363
2-1.947
3-1.285
4-0.939
5-0.756

If anybody have the spec sheet for 4g93p (gti,putr,wira 1.8) plz share with us to make the comparison between proton and mitsubishi spec.

 

[GTpuI]

I get this spec from my surf for 4g93p(r3).This is the difference:
4g93p
POWERTRAIN
ENGINE 4G93P 4-cylinder 16 valve
MAXIMUM POWER
R3- Max output 105kW/140bhp @ 6100rpm
Gti- Max. output 139.9 PS (138.0 bhp) (102.9 kW)@6000 rpm
Eterna- Max output 102.97kW/140ps(138.23hp) @ 6500rpm

MAXIMUM TORQUE
R3- 168 Nm @5600rpm
GTi- 164.0 Nm (121 lbft) (16.7 kgm)@5500 rpm
MITSUBISHI- 166.71 Nm @5000 rpm

Compression ratio
GTi- 10.5:1
Eterna - 9.5:1

TRANSMISSION
5-speed manual

GTi and r3 produce higher bhp in lower rpm.The torque for r3 and gti at higher rpm. So from this spec sheet,what the conclusion? Can ppl or sifu give conclusion?I can see the compression ratio of eterna 4g93 is lower .Thats why it produce slower response than 4g93p.But for high rpm it still can give maximum output like 4g93p.If i am wrong plz correct me.

erm in 4th gear u can go up to 180 actually kekekekeke......
then enter 5th, u need to sleep a while until reach 200 mark....
previously used tis engine b4 but engine kebabomm...but using it's ecu n rojak wiring...

good engine i say.....
