This is also posted on D-series.org also; there's more members on here so I'm sure this has happened to someone here too:

I have installed a camshaft(numbers wore off but I believe its a 59300) on my D15B-VTEC; anyways I can't get this to idle for **** with the stock Z6, Z6 map, stock P08 map and someone's Crower Stg 2 map.
I can't even verify the A/F or datalog since the ports on my computer aren't working(only thing I can get working is the emulator).

For those wondering; I'm using a P28 ECU, LC-1 wideband, custom TTL->serial converter, Moates Ostrich, Crome and Freelog.

I have to open the throttle a tad just to keep it idling around 1000rpm(like not even pressing the pedal...just tapping on it), and if I rev it and try to hold the RPMs to say, around 2000rpm; the rpms would bounce 100-200rpm. Anyone have this problem??? Right now I can't datalog or anything but I'm working on it; just need some help in the mean time. I could install the stock cam, but I don't have my torque wrench with me and I'd rather that be a last resort.


Thanks, Kevin.

 

Just cleaned the IACV, still does same thing. I also tried plugging the IACV and FITV orifice in the throttle body, cleaning the TB, and checked for vacuum leaks.

Any other suggestions would be greatly appreciated.

 

Ok I've noticed that I get either a code 40 or 4 when it's running, but goes away when the car is turn off(comes on after engine is running).

It's actually a code 40 but there's no code 40 listed so it must be code 4? I've followed the flow chart in the Helms manual and it says the sensor is OK(I got 370ohms)

 

bump! Save this SOHC!
