dear all sifu... 4g93 sohc question wif 4g63 ecu

[aivenrolx]

Dear all sifu,....

i had few question to ask...
My project are bot on turbo to 4g93 sohc engine...
I had whole set turbo kit wif 390cc...
And it was low compression piston already...

My question are....
Can my original 4g93 sohc ecu and air fuel change to 4g63 ecu and air fuel?
Witout change wiring... I mean juz plug and play ecu and air fuel...

Or changing it to gsr ecu and air fuel... Witouut wiring?


Coz i dunwan buy piggyback...
Beside...i can get ecu and airfuel cheaper and my future plan change to dohc cost cheaper too....

Just my 2 cent here...

First of all , if you want to b.o.t. your 4g93 sohc engine, you will need to install any piggyback to do a correction regarding the air/fuel ratio when you are boosting later, or not your engine sure will not enough fuel + you also need to install the adjustable fuel regulator.

I prefer for you to go for GSR Ecu and air flow sensor, more reliable for your engine sir. It's more easy to tune with the 390 injector + no need to do a lot of correction when you do tuning later.

Good luck! Any info to add will be more helpful to our member here.

If i am not mistaken, is not the same. If possible, please change the whole engine wayering to GSR engine wayering, it will be more easy for you in the future to do anything regarding the wayering and ecu setup..

Ok...
How bout 4g63 ecu?
I mean evo 1 ecu...

 

[E-Tech]

The 3 socket are the same however there are additional wires and working method which are different....

Evo 1 or gsr ecu can work but lots of rewirind needed..

or

I have seen e-manage blue that able to support your set up...
e-manage- rm850- rm 1 K
greddy map sensor- rm.....
labour charge - rm.......

Oh...thnx for all sifu...
I very apriacate all ur info

lol DUDE
1. SOHC and DOHC Socket 100% not same , NOt complitable
2. if u change evo / GSR wiring also no use . SOHC engine wiring not same with DOHC
Big example : SOHC is Distributor 1 coil 4 plug
DOHC = Sensor control , 2 coil 4 plug

easier setup would be , use back Original ECU , buy Emanage and tune
only 1.4/1.5k
it is BETTER than u change Ecu la . wiring la .. lol waste money
