I'm confused about what is possible with OS swapping and custom OS's. I would like to run the GM flex fuel sensor on my 2000 F-Body PCM. Is it possible to load an OS that offers the flex fuel table onto my PCM?
If that is not possible, could I swap a PCM and wiring harness from a Flex Fuel vehicle?
Did I post this in the wrong forum?
No... anyone who knows hasn't yet seen this thread.
Cool. I was just making sure. I'm not too familiar with this forum or EFIlive for that matter.
Bueller?
How to run your LS1 on E85
I don't think there is an OS that will fit in the 516k 411 PCM for flex fuel,
it's either one or the other.
OS 12216125 from the L59 motors in 2002 Silverados and Yukons (and a few others) is a 512k OS and it has the Flex Fuel tables that use the sensor.
Would I be able to simply load that OS (and update fuel/spark tables, etc) or would I need to rewire everything? Anybody know where I can find wiring diagrams for different models?
I just looked over a 12216125.calz but all the flex options are empty.
If you have a file with values try using that with the sensor.
A few OS' have things that are not used i.e. lean cruise,
finding values to start with may be hard to find.
I downloaded this one: http://holdencrazy.com/EFILive/TuneF...012216125).tun
It has the params table under "B3101 Engine Calibration/Fuel/Flex Fuel" and the stoich conversion under B3101.
I also compared pinouts between the 2002 5.3l and the 2000 5.7l and they are very similar. Maybe 8-9 pin differences (excluding EGR stuff which I don't run).
Is it as simple as loading this different OS onto my PCM and then wiring in the sensor? I'm new to EFIlive.
No you can't just load that in. Each calibration is specific to a platform, eg F-body won't work in a truck (there is more to it than spark and fuel tables). Don't even bother trying.
