0038 - bit 5- O2 Sensor Flag. I uncheck the Set box and change the fuel map to 0. The data display shows no feedback from the O2 and the A/F Base sits @ 100 without movement.

With the O2 enabled the A/F Base trends around 112 and I can watch the O2 gauge swing back and forth in Data Scan.

Why would you suspect the 02 if it does the same thing in open loop?

It's the stock NBO2. I just find it strange that it has this behavior in both open and closed loop.

For some reason I can't get the AFR to stabilize at idle. It will swing from ~13.8 to ~15.3. I've tried tuning it with and without 02 feedback and it still wants to move around. With the 02 feedback turned off and the idle cells @ 0, the WBO2 reads ~13.4 afr. I make the appropriate adjustment and th...

Ok, now on to the next hurdle. I have the Map Tracing function working properly now so I attempted to make some changes to the fueling. The problem that I'm having is that when I go to the corresponding Primary Fuel table in TunerPro I am seeing no effect from my changes. I've shifted the entire tab...

I can say with 99% certainty that it's a Realtime board. TPRT connects and recognizes a Romulator. The owner assured me that it's a CalumSult Realtime daugherboard. The owner also already purchased DataScan. I see a map tracing option. Are you saying it isn't supported for this application? I'm not ...

I'm still unsure of which daughterboard it is. What's the easiest way to determine that? I've managed to get the appropriate drivers loaded and was able to connect with the free version of DataScan. If I'm not mistaken, I should be able to run a consult and TPRT on the same USB cable using the VCP d...

The owner bought the ECU second hand so he doesn't know for sure which daughterboard it is. The #'s on the sticker are: 28 A11-B44 G70 1725 Can you at least tell me if I need a consult software and an ALDL cable to be able to see where in the tables the car is operating? My "real time" tun...

I have taken on the task of tuning a '91 240SX with a Calum ECU. Just getting connected has become a headache. The tutorial that I found looked like it was going to be helpful until I realized the author hadn't completed it. http://www.sr20forum.com/realtime-ecu-support/192443-how-setup-use-tunerpro...
