Ecu wiring question
Hi everybody. I have a Suzuki Reno (Chevy Lacetti) it basically has an obd2 2.0 iron ecotec in it. I bought a used individual throttle body setup and it came with a dtafast e48exp standalone. I live in NYC USA and need the car to pass inspection so going full standalone isn't really an option because the ecu will show that some sensors aren't "ready". Does anyone know if there is a way to wire the e48exp as a piggyback? Or have any other suggestions? Any help is greatly appreciated.

Re: Ecu wiring question

Re: Ecu wiring question
Of course you can wire the EXP as a piggyback.
Although when you dont have the injectors or coils plugged into the factory ecu, it may throw fault codes.
So what level of OBD check do they actually do ? Or what are the requirements of this inspection ?

Re: Ecu wiring question
That's the problem. The coils and injectors are going to thow a fault code and he car will fail. I'm not sure if there's a way to get around that.
Re: Ecu wiring question
Depends on how much the car(drive train) needs the engine ECU, how deep it's all connected together. Otherwise, I would make an wire loom adaptor, and switch ECU's when needed, which I did when I had the P8.
Although, I wouldn't do it(start) with that legacy E48, but it's possible...

Re: Ecu wiring question
Agree with Marco, make it so you can easily swap between the two ecu's then.
But an E48 is pretty basic, wouldnt be my first choice

Re: Ecu wiring question
Haltech makes a dummy load box for ignition and injectors, specifically made for piggy-back situations with a stand-alone.

Re: Ecu wiring question
Thanks so much for the help guys. That haltech unit actually looks pretty good. My tuners going to look into it and see what he thinks. I'm trying to stick with the e48 because of money being short. The price on the haltech makes it more interesting haha. I'll let you know what I come up with.
