2016 sho sct tunning issues

[SHOurpp]

im not sure if sct has released anything this whole year that helps me tune this car.it seem like they are way behind in updates.
anyway

for whatever reason
AFR BANK ONE in my car is intermittent.i can drive  20 miles without it ever reading, park the car, come back out 10 min later and its now working and reading= wt f
this is of course after it was working the night before and a brand new flash.
checked for leaks around both d/ps and all 4 sensors- none- all 4 sensors plugged in- none rubbing/bent or twisted under the car.????

bank 2 sensor 1- doesn't read at all-period- but it knows cat temperature OF 700 degrees???
no other pid tables will it read on that sensor at all.
more confusion
short term fuel trim is fine

car wot is set for .80 Target but third gear starts going .90-100 even though ive commanded not to lean out???

any insight would be profound thanks

I would say your car has been tuneable for a while....i think you are reaching at this point in thinking sct is your problem

Based on what you say its hard to even tell for sure if you even have a problem or if there is a mechanical problem you are all over the map.

Could you be mis interpreting the readings?

Any other symptoms?

Programming on these isnt always simple so if your change doesnt give what is expected its quite possible you missed something rather than a lack of functionality

 

[SHOurpp]

Any other symptoms?no -

intermittent Afr bank 1- cant continue without a solid working one.
- why isn't it working? do these things fail in 4000 miles
has anyone else had this?

bank 2 doesn't read at all - self explanatory -only reads cat temp on cat less down pipes
why?

this isn't tuning- this is why isn't it reading

 

[ajpturbo]

You should post a log of a good WOT pull with enough items to adequately show the sensors in question...Your posts are way to vague for people to help you.

Just a wild guess on my part but you have a new SHO that would seem unlikely to me that you are having all the issues you think you are having.

Have you begun to spray your meth yet that you spoke of before and have you done much wiring? You were also having problems with your flashing...I'm starting to wonder if they could be related

 

[SHOdded]

I agree, revert to stock and evaluate.  Then list all the mods you have made (hardware) and evaluate with a canned tune.  But if you have a meth kit installed, a canned tune will not work anyway.

 

[SHOurpp]

okay lets clear the mud:no meth yet- 2 bar stock map.
sct doesn't support 2016 sho cars- thats direct from scts mouth on the second lock up.
if you scan the x4 box for compatibility -there is none.

unless you use 2013-2014 strategy and tune from there(not giving away any tuners secrets)-THERE IS NO 2015-2016 SUPPORT
there is no value files,no dmr list for 2016-
its such fun going back to 2014  to read the descriptions of what your changing-
sct live link has no updates for 2016, no descriptions or dmr period.
yes you can tune the car-but is it giving you what you need to do it right - hardly

back to stock-pay attention here.
tuners and non tuners welcome to reply- im not a dealer/tuner

lams bank 1 and 2 are copies of each other exactly.
does the car not use bank 2 like the f-150?my car has no reading on bank 2 on its own.
cat temps are identical copies on bank 1 and 2.
measured afr only works on bank 1
ltft is 0 on both banks
afr bank 2 is o- it doesn't read
stftr reads identical as bank 1

(unless you tune yourself im not expecting  any answers you will not know what im talking about)

There is no problem tuning 2015 or 2016 sho's

Everything is there to tune those

The only thing sct means by no support is that there are no canned tunes that available nor can you buy an x4 with pre-loaded tunes

The customer service rep was ill informed and mis spoke

What version of live link are you using?

2015 AJP tuned chiming in. No issues tuning my car, the strategy is supported etc. Like I told you a long long time ago, 13+ does not have canned tune support, you need a good custom tune.

Banks 1 and 2 are not copies of each other on my car, if they were copies, ford would not have spent time/money to  put in sensors on bank 2. It seems you may still be having bad flashes/issues flashing a tune, possibly even something going on with your ECU, or issues with hardware install, but not saying any of that is the case, just possibilities from what I have seen.

 

[SHOurpp]

live link version?-since i just downloaded it last month -hopefully the latest?? ill get back to you ajp

i also have a code 2251 that just showed up- bank or fuel related- im sure

ill post my stock log showing more

its not reading BANK 2 STOCK

 

[ajpturbo]

Post whatever log/tune is showing what you are describing.

Open livelink and look in the top left of the screen..It will show the version

 

[ajpturbo]

That dtc is a wiring problem it seems...So being that you did downpipes it doesn't seem impossible that something happened to the wires and or the sensors.....And it's really starting to seem like you may have electrical gremlins being that you had a lot of difficulty with the flashing and now this

I wouldn't even attempt throwing a tune back on until you can make a good log with the stock tune.

Senor 1 of both banks should display readings and LAMBSE for both banks should display the same

You can believe it or not the choice is your's but I assure you there is complete tune ability for your SHO.

Value files from SCT are only values that SCT puts in their software for tuners to use if they want and quite honestly I don't care to use any of them for the SHO...Some are good some are not.

But even if there are none available the tuner is free to make any changes to the tune they want as long as the strategy is available...And obviously if you have flashed a tune then your strategy is available.

You can not flash another strategy to an ECU that is different...You can copy values from a different strategy and import them to your strategy but that can also cause lockups with the flash...I say that because you mentioned that you were using 2013/14 values...Something to think about maybe

 

[ajpturbo]

Any updates on this?...logs? Livelink version?

 

[ajpturbo]

unless you use 2013-2014 strategy and tune from there(not giving away any tuners secrets)-THERE IS NO 2015-2016 SUPPORT

You dont have the same software the dealers have so there aren't really any secrets you can give away.

2017 strategies are added daily as they are requested...the 2015-2016 strategies are becoming old news at this point

 

[SHOurpp]

im buying a new oxygen sensor for front cylinders  per code 2251
bank 2 sensor 1- front of car-wires routed to the cooling fans(i believe thats the right one) correct me if im wrong here please.
if ajp is right and the wires got pinched or pulled on the down pipes ,the stft and ltft will default to the working sensor.
thats why they are copies of each other; it throws code because afr isn't reading right

i looked at the canned tune for 2013 and 14
the only fueling change made by sct was lowering the temp so the engine would  go open/closed loop faster.

just a shame they haven't added dmr or value files for 2 years

 

[ajpturbo]

Not much has changed for 2015-2016 ...there are only 2 main families of tunes for the SHO
2010-2012 and 3013+

Everything thing for 2013+ is about the same....doesnt matter if you have 2010-2012 or 2013+ every strategy has small differences

You never listed what version of live link you are running...there are plenty of 2015 ive seen that log dmr's

I think for 2013+ all the direct memory read(DMR) addresses are the same

 

[SHOurpp]

here is the log - stock reading

 

[ajpturbo]

Your car is all sorts of jacked up at the moment.

Your DTC is for bank 1 and it's your bank 2 that seems to be the main culprit possibly....Your bank 2 measured afr doesn't read at all. That, I think is causing your car to kick into some mode where it's using bank 1 for fuel corrections which is why your stft's are identical. But even your stft's are not reading all the time which is even more weird.

You say you are commanding .80 at WOT....You have not done any fuel tuning...Your target actually changes from 1.00 down to .71...And it looks to be the stock fuel curve to me...Your desired TIP is all over the place too meaning that your commanded boost is ALL over the place

If you think you are commanding .80 lambda you have done it wrong. Look at LAMBSE that is what you are commanding.

If your sensors are good then you have serious electrical and wiring problems . IF your sensors are bad then that might explains some things. But the DTC you had 2251 is an electrical or wiring problem and not a bad component.

And the other flashing problems that caused your ECU to lock up also tell me you have electrical problems....You mentioned you had devices hardwired to the car, you have to be really careful with new cars...Maybe you have interference or are getting feedback into the HS canbus or MS canbus which would screw things terribly.

Look at your torque source too...You are getting 1 at WOT. The measured torque is getting truncated which means the ECU is not even seeing or outputting the correct amount of torque which means other actions are interpreting correctly.

Your throttle is never fully opening when you are at WOT it's like half open.

I would replace both primary 02 sensors and strip the car of your hardwired devices and do some logging....But your car is a 2016 so if your 02 sensors are bad you really mangled them on your downpipe install, which makes me thing you have a wiring problem or injected electrical interference into the ECU/canbus/OBD
