It also appears the exhaust temp table has been modded. The values entered will also be causing issue. The valve in the tables are zero from stock

Interesting, the stock file we do paired it to was set to just over 1000 degrees also. But either way he's happy to try it to 280.

The other thing I was thinking was since its dropping 17% of fuel at idle could it be too rich to start with and it's going over a threshold?

Trim should be good for around 25% but if your seeing 17% the injector values could probably use some work.

I'm interested to hear why he (if it was him) adjusted the values in the exhaust temp table? the PCM uses an inferred value for this so you don't need to touch them.

Interestingly it looks like it could be a quick way to force open loop for tuning the airflow tables.

Nah he's fixing up a previous tune from a different company, he's just so much easier to work with and helpful

He's modified mapping, injector scaling, boost curve and timing. Rest was from what was done previously.

Was originally running 13.5:1 a/f on boost and some other issues.

He's thinking about changing the mapping on idle to bring the ltft down if need be

get a stock map and start from that, rather than finding any other nasty surprises

That's what I thought was going to happen but he's happy for me to come back everyday and fix things if need be.

There's limited tuners in tassie so I want him to be happy to help fix it

As Ratter said. Get a stock tune and start from that. You should be able to get +5 -5 trims very easily by juggling low slope and inj offset.

What they mean is get ford (or someone with the appropriate flasher, to flash in the correct stock file for your model.. Starting with a virgin file isually gets rid of annoying bugs, especially if previously tuned with sct... Tuner should know this anyway? Sounds like he may do more commodores then falcons?

that's fair enough, and ideally is what should have been done, ill speak to him tomorrow about it.

Having loaded my tuned file up against a stock one that's on hp tuners forum, there are a few differences, some understandable like boost, timing mapping etc.

I can understand the changes in the spark tab, and most of the torque management (not sure why torque module switch has been turned off?)

Likewise changes to the injector flow rates I can understand that change, but the changes in cat over temp? Not sure why that's been disabled?

Importantly, the open and closed loop tab, the CL 02 sensor temp is the same as the stock one at 1093 deg?

Im just curious about this for my benefit

What injectors are you running.

If you are out by as much as 17%, I find (on my FG) that it does not like to go into closed loop at idle when fuel trims are really off.

Put stock injectors in and go to Ford to get reflashed if you have to.
