I've been busy trying to finish building our home before xmas. Doesn't look like I am goin to finish it, but hopefully I will get to look into the a/c issue a bit closer as the wife is taking the car for a trip straight after xmas. I suspect the a/c compressor stays on permanently when the fan is on as the system has now overloaded a couple of times.

Without an AU to do testing on this will be difficult for me to resolve. If you can test the A/C inputs/outputs as per the factory wiring diagram both with and without the chip that would give me something to work with. I still think the issue relates to climate control base binaries with non-climate control cars but need to gather info. It's important to note that most of my customers with AU chips have not experienced this issue, so there is something specific that im missing. Both of your cars are non-climate, right? See this link for factory ECU pinout: http://www.fordforums.com.au/showthread.php?t=11244617 If you have a multimeter and you can complete this table with/without the J3 and PM them to me, that would help a lot! Code: A/C Off Fan Off A/C Off Fan On A/C On Fan On Pin 69 14.5 14.5 x Pin 86 x 5.6V - 13.8V 1 - 4 On Fan Select. Pin 92 x x 13.7 Pin 93 x x x Cheers, Jason Interestingly enough I have nothing (no wire) from pin 93 so i didn't test it. Perhaps this is the variation ? That was tested with the J3 out. It's too hot to go put it back in and go through that again  I'm going to go find somewhere wet...Guys, have we got any closer to resolving the air con issues ? I also have similar problems to these guys. I have an AU1 , converted from auto to manual, and running a VCT motor and loom with the standard original ecu and J3 chip. The VCT is working fine. Cheers Mike Here is what I got, pin 93 has no connection & I got the same results whether the j3 was in or not: Code: A/C Off Fan Off A/C Off Fan On A/C On Fan On Pin 69 14.08 14.01 14.01 Pin 86 0.01 5.4V - 14.01 5.4V - 14.01 Pin 92 0.28 0.28 13.61 Pin 93 N/C N/C N/C Go figure........For some reason plugging in the j3 changes the way the ecu switches the a/c?? There must be another connection to switch the a/c from the ecu that is different to this pinout? I need to check the wiring diagrams again. I vaguely remember there being a difference between AU S1 & 2/3 in the a/c schematic. Shane |

All four pins had the same results with or without the J3?
Odd! BTW, it's not possible for it to be the J3 itself, it's got to be the program on it - we just need to find out why... Cheers, Jason

I'm not complaining at all as a paying customer, which is why i'm not whinging or trying to return it. I'm happy with how the motor runs with it, which proves to me it works, just a few bugs need sorting with the au's programming apparently.
I'm confident Jason will get to the bottom of it.

When I had my wolf done Robbie said the other AU he did had different aircon bits.
Mine had an extra sensor and it was a bit of a f**k to get it working right. I cant remember but Im pretty sure the J3 worked ok for me with the aircon. |

Not complaining either, but probably going to sell the xr6 now & will need to keep the j3 out as I could not sell the car like that. Mainly because the a/c will probably get stuffed unless very conscious driver. Maybe the a/c is not noticed much as most of the guys who are chasing performance don't care much for a power guzzling a/c? That is if this issue is wide spread - it may not be. All I know is both the AU2&3 that I have tried the j3 on have caused this problem. Not sure how easy it will be to find this bug though - anyone near Jason with a AU2/3 & a/c issue for testing??

Have you tried sucking the tune file out of your stock ECU and modifying that with your J3 rather than using a file off the website?
That's what I did. |

No as the xr6 had the wrong ecu installed so I got Jason to program the j3 back to factory plus tune for 98/lpg. The other car I changed the ecu using j3 to lpg factory program. Jason programmed it again for me. Shane |

You posted the same question on boostedfalcon.net. I replied there as I saw it first!

I understand that the EECV trims fuel based on O2 sensor readings. I have taken a good look a the EF bins, but cannot find variables for Short Term Fuel Trim or Long Term Fuel Trim. Is there some way we can see these numbers? Or are they just labeled something else?
Also, is there a spark trim function as well (ie, trimming spark long term based on knock sensor pings)? Thanks for your help.

The fuel trims are held in RAM inside the EEC. They are not parameters you set in the ROM.
Cheers, Jason

Thanks. I was just hoping they could be readable, as a tuning aid.
Cheers.
