Perfect, thanks! I will check the thermostat housing ground.

Still baffled as to why there was a wire spliced to the TPS signal.

On my p28 when I started the car for the first time this year, it was getting no TPS signal. I checked the wire and someone had spliced another wire into the TPS one, which I somehow accidentally ran to ground because I thought that’s where it went before. Probably my mistake. I cut that wire and TP...

Yes that is the plan once I get the wideband calibrated correctly in Smanager.

Thanks for the help gents

Thanks. Can I cut the wire currently going to D10, or do I need to splice into it?

Is removing the resistors 100% necessary, or should I see how it works first while leaving them in?

OK that made me more confused about cutting the harness off a dead sensor. I have my stock narrowband still running for closed loop. I have my wideband running the gauge only and want to hook it up to ecu for datalogging the easiest way possible. The white wire should run to the ecu, is there a simp...

So I have an older aem wideband (probably 7 years or so) installed by previous owner that was never wired to the ecu. Looking to hook this up finally. It’s a P28 with S300v3, running a B18c1. Car was a ‘91 obd0 coverted to OBD1. Now, I understand I should be running the white wire to D10. Is it okay...

Awesome info, thank you!

At 6300rpm I am at 13.77ms injector pulse and 72% duty cycle at full boost. Is there an equation to figure out maximum pulse at 8000rpm, or better yet what my estimated duty cycle at 8000rpm would be assuming the same pulse width? I know there is a relation between injector ms and rpm, just want to ...

It seems to have worked perfectly, thank you!

I have now learned the importance of proper dead times through first hand experience. I am still tuning my fuel tables in open loop, and thought I had it dialed in for low load, idle and cruising conditions. The other day after getting back into the city on a warm evening and a decent cruise on the ...

To put some resolution to this thread... I believe the issue is that with colder ECT and IAT it was compensating with more fuel. Under certain conditions it was running excessively rich to the point of misfiring. Even when warmed up, under heavy throttle, lower RPM it was running pegged rich. So I a...

Need some help understanding the closed loop parameters and how they function. Say I am tuned in open loop so at cruising I am around 13.5-14:1 AFR. When I run in closed loop, it bounces from 13 all the way to 16+, back and forth constantly and I can feel the car lurching slightly due to it getting ...

Yeah I realize, it is not tuned yet, just running on an old tune from before I replaced the S300, so there have been some issues. The 30% was added to the original P72 basemap to account for e85 vs gas, and the injectors scaled to 1000cc just to get it running. So it is still a basemap, and I am sta...

After taking some readings from my wideband gauge and comparing it to the Lambda voltage showing in SManager, I believe this is what the voltages are equating to in actual AFR... Volts----AFR 0.00-----17 0.25-----16 0.50-----15 0.75-----14 1.00-----13 1.25-----12 1.50-----11 1.75-----10 Or something...

Fuel trim is at 30% I think for the e85. I have actual flow rate and dead times which I am going to fix once I start fine tuning fuel tables in open loop.
