I've just spent 4 hours of my life researching ECUs it seems like some of the info is somewhat outdated. I'm putting a S5 JDM Turbo engine into S5 GXL using a USDM harness. My swap comes with a JDM AFM, Boost Sensor, and ECU.

The ECU is probably a N374, so I'm wondering if there is any viable way to salvage the ECU.

I know the following:
-It will work if I hit the lottery and get an Knightsport chipped ecu
-Rtek only has chips for N370 for the S5 so out the picture

So what are my options, or should I just find myself n370

 

sometimes they work, sometimes they don't. if it doesn't just get the correct ecu.

 

I think the RTEK chip will fix the ECU since the problem is in the EEPROM chip which they replace, I think I spoke with turbo2ltr (rtek guy) about mine but I'm not 100% sure so you should talk to them. There are no other options besides buying an N370 which are quite rare and usually go for 100-$200.

 

I would try to find a n370 USDM AFM and boost sensor. It seems like less hassle in the long run. Just my opinion.

 

oh... I thought AFM and Boost Sensors were not JDM/USDM specific. Can anyone confirm this?

So what do people do with all their n374s?

 

the afm & map sensors are the same. you can use the ones from the swap.

 

Thanks for the clarification T-66. Looks like I threadjacked myself.
