Ok, first things first ... please post the .bin file you have modified for MPFI.

I don't have one of those.I won't be getting a wb o2 any time soon but the info is good for future reference. The 7427 (bjxk)I have is stock accept the jumpers soldered onto sense resistors.I'm unclear on what would need to be done to enable mpfi programming wise.and disabling transmission control.also still pretty unclear on tunerpro of what's what and in the parameter tree what things u could or would adjust and what u shouldn't touch.scalers.flags.tables.I don't know how to use or what an Excell spread sheet is.I am currently running 7747 asdm and have a few logs.I haven't figured out how to post one yet.sorry.I got alot to learn don't I. I've just been looking at the tunerpro and reading the tutorials from sixshooter. I hadn't planned to swap to 7427 till I understand how to use the features in tunerpro.I'll keep reading

Thanks for the clarification. I think I had most of that figured.it was the flags scalers and tables I was confused with. I think I can play and explore a little more now.as I mentioned I have a few data logs .but I was not able to find the bin for my ecm (7747 asdm) so I just used a few that were close so I could get some data to see how it's running.I thought I could get data logs and use that info to make some changes for the 7427 that's gonna be swapped in.make changes to that bin and burn that to a chip once I get my hardware. I'd like to post the logs I have to see if you can give me some clues as to what to change.would it be a good idea to try to get the cadillac 2240 ecm bin and copy things like the timing and fuel to the bin I plan to use on the 7427.thanks.btw the laptop I'm using for this does not have Web Access so I just copy what I need to memory stick and load to laptop.

Using a 7427 bjyb bin in flags if I flag manual transmission does that alone disabled the transmission controls or do other items need to be changed as well.

To view parameter comments and tips, use the F10 key after opening a parameter. For example open Manual Transmission and press the F10 key.

See example below.

After setting manual transmission and related parameters from the "Comments", I would also disable the automatic transmission codes.
