I was able to resolve the issue by doing the following

Ignition in Accessory position (engine off)
Link to S300v3
Go to Nitrous/Aux 1, Function "Nitrous control", Input and change the Arming input setting to "disable", the change Function to "Disable"
Upload to S300v3
Turn ignition off, wait 10sec ...

I will get the datalogs tomorrow

Well yes, I understand that. When I disbable the nitrous control, the engine wont rev past 2K rpm

I didnt tune it. It was tuned by someone else. AC was added after the fact. I only notice AC would work with Nitrous disable. Ive tried to contact thr person that setup the S300 and theyre not responding

The AC will work with this ECU if if the Nitrous function is disabled. However the engine will boog down at 2K RPM with the Nitrous function enabled. This car is an all motor vehicle with no nitrous or force induction.

Hello,
I'm having a similar issue. I've verified wiring, relays, & connections. Unable to activate AC clutch through test mode

So I'm a little new at this when it comes to the S300 and forced induction setups. I'm using a stock o2 sensor. Do I need to replace that with a Wideband o2 sensor?

I was able to get it started, however engine seems like it wants to stall when throttle is opened a little bit. Then it seems ok and starts to bog as throttle is opened more. I calibrated the TPS and updated the fuel injector setting. I'm also using a Adj Paxton fuel pressure regulator. Fuel ...

Hello. I was wondering if I could use the the posted calibration B18c5 JRSC LHT modified with 550cc injectors for my setup below to just get it started and possibly drive to my tuner.
