RPM issue

[Gman53]

Hello all,

I am new to tuning and I recently installed a s300 ecu into my 92 Integra with a b18c1 swap.

The problem I am having is that the motor is unable to hold steady rpms from anything over 2000 to 4000 rpm. It keeps bucking out back to idle which makes me think the injectors are cutting out. I was reading to adjust the TPS on Smanager which I have tried, decreasing the MAP pressure, although even after lowering it from default 22Kpa to as low as 15Kpa, I am still having this strange problem.

This problem only started occurring after I switched to s300, as my stock ecu did not have this problem.

Any help is much appreciated

Post the calibration as well as a datalog made with that calibration that shows the issue.

Sorry for late response, was busy with school work. I'm not sure the procedure to do the calibration. Any help on how to do so?

Thanks

By calibration, he means the tune. It's the file on the computer that ends with .skl
