Been reading about fuel trims on the forum and decided to look at mine on the iCarSoft V1.0.
I get this at idle with live data after 20 minute drive:


From what I have read they should be around 0 plus or minus 10%? No MIL/CEL lights. Two codes P1000 and P1582
which I have mentioned previously. Car a bit hard to start but otherwise seems to run fine. I have cleaned the MAF with MAF cleaner several times and also swapped it with a cheap one from Amazon. With the cheap one installed the ST trims drop to about 115% but otherwise not much better.

To worry or not to worry, that is the question.

 

After 20min driving it should be in closed loop (using o2 sensors to adjust the fuel trims)
Not familiar with the icarsoft but it looks like o2 sensors are off, So maybe its in open loop and not closed loop.

It wont set a mil/cel light until one trim maxes out at 25%

Yes long term bank 2 is high (no data for bank 1)...

 

With P1000 it is severely restricted in knowing what is trustworthy and what isn't so can only flag a reduced set of codes. Do what you can to set the rest of the monitors to get P1111 and then it can flag any code and you may get extra helpful hints as to what is wrong.

 

O2 is cycling off then on every 1 second Just happened to be off in this pic.

Max at 25%? Mine are 130%!

 

The engine would be in restricted mode at 25+. Maybe a decimal point missing. 130 does not make sense.

 

Definitely not restricted mode. I am going to visit a friend with an 04 XKR this weekend. I will put the
iCarsoft on hers and compare.


Shouldn’t the Mass Air Flow be 14.1?

 

As RJ237 said looks like decimal point missing...
I took it to read..
LTFT B2 +13.7%
STFT B1 +12.9%
STFT B2 +13.0%

As JagV8 said p1000 is telling you the ECM/OBD monitor test is not complete (one or more monitors have not passed the ECM/OBD monitoring tests).
You need to get P1000 to change to P1111.....

To see what monitor/monitors have not yet set (passed) you need to look at diagnostic mode $06 (component id $11)...

Strange for the o2's to cycle on/off (but like i said, im not familiar with the icarsoft)...

The mass air flow rate g/s will change with rpm/load etc.......6.56 g/s will roughly be 650/700 rpm in park.

 

Just now. I had the battery disconnected a couple of days ago so I figured it had something to do with the Drive Cycle.
In the past the more I drive it the more modules are completed.

 

Made a significant iCarsoft discovery. The pics I posted earlier are from the Live Data section under the DIAGNOSTIC tab of the iCarsoft main menu. I did not realize there was Live Data available under the OBDII tab. Not sure why the numbers are different but this pic show numbers much closer to normal. These are at idle from a cold start.
