Turbo ECU in Non-Turbo

[nates6969]

Hey, I'm in the process of turboing my 1991 N/T but still a long ways away. I have pretty much all of the parts including a tubro ecu that has already been rebuilt and has never had problems. My car currently has very bad idle surge when cold then idles low when hot. My IAC seems fine, I believe my current ECU has leaked and has ruined the IAC drivers. I took it apart and it looks like they have leaked. My question is, in the mean time before I get the rest of the turbo parts in, can I use my turbo ecu in my non turbo ecus place just to check if the Idle surge goes away? I know the injectors run at a different resistance (about 15 ohms N/T and 10 ohms turbo with resistor pack) is this difference enough to cause damage at all? and and MAS is also difference, will the N/T still work or short something in the ECU? thanks!

I have a feeling it won't work at all, but hopefully somebody on here tells me wrong.

No, it will not work.

I've seen people do turbo ECU swaps to non turbo cars. But I think it depends what engine is in your car. The only turbo ECU swaps that I have seen done were on 2g Spyder GS's, but the 4g64 from these cars are very similar to the 4g63 motors so maybe thats why it works. IDK, I hope I didn't confuse you too much and I hope this helps some.

I don't see why it wouldnt work though, the ecus are almost identical except for the knock board, an extra pin for the mas, and a couple of controllers for the turbo (bcs and fps). These changes shouldnt effect running, maybe throw a CEL. The only one I question is the fuel injector resistances are slightly different when considering the resistor pack.
