I do believe the FS-ZE ecu is ODB1 and everything in the US is ODB2. I remember seeing the only way to get the ECU to work is to pull out every single wiring harness that came with the car and then get all the japanese ones and put those in. Dunno if any of the other sensors or whatever else is plugged in there will work tho.hey guys I just did the swap like yesterday (fs-ze) and my car is running fine well not really, on the stock ecu, and the JDM ecu is not a direct plug and play. Does anybody know how to wire one?
this is a terrible idea for exactly the reasons listed. the compression is far too high for any kind of turbocharging. i don't care if you have a unichip, a microtech, a haltech, a split second or the almighty father tuning your protege. you will not be able to run any amount of boost without blowing this engine to pieces.Hey, I'm getting my FS-ZE this week. I'm just curious to see if there have been any more solutions of problems discovered since this forum was last visited ? I'm planning on running it in my MSP. I have the UNICHIP and was planning on getting it tuned. Is the UNICHIP tunible to the levels that will be needed to get this running right or will I need to go with something else ?
We've finally got the Unichip Q to completely control fuel... unfortunately, that's with the OBDI engine with the O2 sensor unplugged to remove the closed loop region. The Q also has a delimiter option to free up those extra rpms, but that's a separate module and may not be available with Stateside vendors. If your current Unichip has the proper options, you can actually use it to modify your O2 output to trim closed loop AF, but I think the MSP Unichip is a generation older than mine.Hey, I'm getting my FS-ZE this week.

Sorry to burst your bubble, but I HIGHLY DOUBT that you have an FS-ZE engine.Awesome thread! OK so after long drawn out drama with this car, I managed to get another FS-DE in my P5... However after consulting with the mechanic who did the swap, and what's been said here, I think I have an FS-ZE, minus the intake mani, ECU, cat. converter, and wire harness(s). Reading this thread made all the pieces seem to fit...
The engine runs great, (around 42k miles), and is in fact a little more powerful. However I'm not concerned about getting the power that I paid for (I just want a working car), but rather a check engine light that came on recently. It came on under regular driving conditions accompanied with no noticeable changes in performance or sound or etc. Is this just the USDM ECU freaking out, or should I go and get a code pulled? Anyone else have this problem?
**BTW: The mechanic got this new motor as a "JDM FS-DE," but from what I've read, there is no such thing as a JDM FS-DE?
