Hi there.
I'm the new owner of a JDM 1996 Integra Type-R which came fitted with an S300. The previous owner had a built B18C-R engine (Blox cams, etc) for this car, but it managed to self destruct on him (valve dropped on a warm up lap). He replaced the built engine with a standard B18C-R engine, and rather than paying for a retune just left the tune that was on the S300 for the built engine.
It had a lot of flat spots (ie, driving along and acceleration would surge), and the idle would surge horribly and not change depending on how the car had been driven, however, it never threw any error codes.
The first thing I did when I got the car was track down a standard tune, I ended up using this one here, after loading this tune on (The firmware was updated before hand automatically) I had three error codes, Injectors, BARO and Oxygen Sensor (Number 42 I think from memory?). I managed to find the differences between the two on the Misc page of the Parameters options and selected disable Injector and Barmetric Pressure Sensor codes, but the Oxy code is still coming up. I also noticed that Disable ELD was ticked on the blox tune, but I'm sure when I had this ticked on the standard tune the car would not start (I may be wrong on this), I'm not to sure what the electricl load detector does in the first place.
The origional blox tune is here:

The tune im running now, is here:

If someone could shed some light on why i'm now getting the Oxy error and why the idle is surging, that would be fantastic!
Surging Idle/Oxy Error Code
If it is a JDM ECU then disable the injector error, ELD and BARO sensor. As for the o2 sensor - you'll have substitute an o2 sensor and then trace wires and check the connectors are good. Chances are the sensor has seen too much vibration.
You'll need to get the car dyno tuned sooner or later, espeically so if you can feel flat spots.

If I load the blox tune back onto the computer, the oxygen sensor error disappears, so I can't see how it's an issue with the wiring.Hondata wrote:If it is a JDM ECU then disable the injector error, ELD and BARO sensor.

The car had flat spots with the blox tune, since I put the standard tune back onto it, it feels like a new car.Hondata wrote:You'll need to get the car dyno tuned sooner or later, espeically so if you can feel flat spots.
