Would I be correct in assuming this enriches the tune when the A/C is on?

I've got an Ecotec running on an 082 ecu with 12P, and it runs lean when you first turn the A/C on.

Thanks,
Dave

Thanks mate, found it.

Idle Fuel Param - Delay before using idle A/F ratio(manual & Auto in Drive) was set to 18 secs.

Is there a setting in 12P to change the amount of time the ECU stays in closed loop after it drops back to idle? The engine idles smoothly at 13.2 afr, but when I pull up at a set of lights it stays in closed loop, so is idling at 14.7, which makes the idle stutter, after around 10-15 seconds it dro...

Have you actually physically measured the voltage with a meter to confirm if its really reading like this? Have you even bothered to read my replies, how did you think I was reading the voltages at the ECU/TPS switch, of course I was using a multimeter. could be a faulty ADC on the ECU if the wirin...

OK so where can the fault actually be then? I've tested all the wiring. I've tested 2 different ECU's, and tried 3 TPS's. C14 has 5.01v coming out of the ECU feeding the TPS and MAP Sensor, I see 4.91v at the TPS, and the MAP sensor is reading correctly, so we can pretty much rule out there being a ...

Now that VL400 has pointed out what the problem was, the changes make sense to me. I've put the engine into a vehicle that in its current trim would easily weigh 350kgs more then the Commodore it came out of, not to mention, it has the aerodynamics of a brick. Of course you're going to have to bury ...

You will need to change the item "Malf 19 - Min Delta TPS Between Loops" to 1.17% and "Malf 19 - Max MAP for error condition" to around 50 kPa. Then if its still being set, which is likely, adjust the table "Malf 19 - Expected TPS vs RPM" In the log you posted at the p...

That is the XDL that I took that screen capture from, but I mustn't have reset the ECU before I took that log.

Just went back through some older logs, this one starts off with the code clear, then changes to Set at 1.22 min mark.

This is my first time tuning with Tuner Pro RT, so I'm probably doing something wrong mate. :) Here's how I've been doing it. Startup Tuner Pro RT, under Acquisition, choose Load Definition File, and choose "OSE_$12PV112_1BAR - Petrol with calcVE.adx", then again under Acquisition, choose ...

Hey Everyone, Just put an ecotec out of a VX into a 4runner, running an 082 ECU with 12p (OSE $12P V112 BLCD V6) on a homemade ds1230y - 100+ memcal, all seems to be working sweet, with the exception of one thing, the TPS is giving me weird results in Tuner Pro RT (using the OSE_$12PV112_1BAR - Petr...
