Thread: tuning or modding sr16ve ecu

im running a b13 se-r ecu on my b14 with jdm engine harness , with the b13 ecu with calum basic runs hard but its always surging for idle and intermittenly but happens alot my car would rev to about 2000 rpms or less and engine feels like it stalls for a split second them kicks back in and does that till i press in the clutch and let it idle for a few secs them goes awaybut comes back if i stop at a light and take off again. with the sr16ve ecu the engine idles great no issues what so ever but its alot slower them the calum ecu but does have better gas mileage. my question is if there anyway i can get my ecu tuned with a calum program or any good performing program ? any info would be great
