You're right. Still having problem with wideband closed loop. Was trying to figure out if it whether it's a problem with the ECU or wideband controller.

Fixed the issue of ECU resetting for us.

Another problem that seems to have gone away is when we were using wideband signal for closed loop, intermittently (although more often than not) when the car went in to closed loop conditions the wideband signal would go to ~9:1AFR. As soon as we got out ...

thanks for the clarification!

Wondering if anyone knows why the stock maps have ignition advance built in to them in 4th and 5th gear. 30% in 4th and 44% in 5th gear seems like quite a bit. I can't make sense of it from an OEM point of view having to do with emissions, performance or otherwise.

Any ideas?

We're getting in to ...

What is the limit for powering additional sensors off the ECU 5V out?

I'd like to run additional MAP and possibly 2 or three additional sensors. I'm guessing these sensors draw around 100mA? And the voltage regulators are probably 1A? Please confirm.

I am also very interested in this application. I've been using AIM Evo3 and XG Log.

Where should I pull the power for the O2 heater? Is it okay to draw load from the ECU power/ground (A25/A26)?
