Resolved 1G knock sensor

[95tale]

Ok I have looked and looked and cant find anything on how to wire in a knock sensor to a non turbo engine wiring harness. I have a 93 eclipse gs and am swapping to the 4g63t. I know I need a turbo ecu. does it also just plug in where my old ecu would be or do I have to do some rewiring to make it fit ?

The below is from: http://www.dsmtuners.com/forums/articles-turbo-system-intercooler/48231-installing-turbo-4g63-into-nt-4g63.html#post425068. I'd suggest you read the rest of it if you have any questions related to turbocharging a non-turbo 4G63 1G DSM.

ecu and wiring harness:​

here is the 1g turbo ecu color coded pinouts, this is invaluable when working with the engine wiring harness: http://www.dsmtalk.com/gallery/data/500/drawing2_model_1_.jpg

you will need the turbo ecu. Simple as that.

You can either obtain a stock 1g turbo engine wiring harness or modify your factory non/turbo harness by adding the following wires:

7th wire from mas - the 7th wire from the mas needs to be run back to ecu pin #6. This wire is for the stock boost gauge (which is worthless anyways) so you can skip this step and use the stock n/t mas, especially if you are keeping the n/t gauge cluster (as it doesn't even have the boost gauge. Either way, make sure you buy a real boost gauge.

knock sensor - one wire can be grounded to the engine bay somehow, the other white wire needs to be run back to ecu pin #9.

wastegate solenoid - one wire here will be grounded, the other returns to the ecu pin #105. Or you can switch to a manual boost controller (mbc), in which case this solenoid will be unnecessary.

injector resistor pack - here is a tech article written by timg on how to wire the fuel injector resistor pack into a non-turbo harness: http://www.dsmtuners.com/forums/articles-electrical-wiring/174314-injector-resistor-pack-wiring-1g-n-t-turbo-conversion.html

here are the factory ecu prints. The highlighted ones need added, and the model is in the upper corner so you don't get confused.

Im not turboing a non turbo 4g63 im swapping to the 4g63t engine but I have the non turbo harness

Oh, my mistake.

Try this instead: http://www.dsmtuners.com/forums/articles-turbo-system-intercooler/48231-installing-turbo-4g63-into-nt-4g63.html#post425068. I'd suggest you read the rest of it if you have any questions related to swapping a turbo 4G63 into a DSM with a non-turbo harness.

Ok thank u

Is the fuel injector resistor pack a must I have some 450cc injectors

 

[19Eclipse90]

Yes, it is necessary. The below is from: http://www.dsmtuners.com/forums/newbie-forum/178207-injector-colors-whats-diff.html#post1489058.

...turbo cars have an injector resistor pack on the firewall to provide current limiting since the ECUs use the same injector drivers for Turbo and Non-Turbo. Putting low impedance injectors in a N/T car will burn out the drivers without the resistor.
