So Im about to begin fabrication of my single turbo setup and want to know if this works. Ive read through http://nefariousmotorsports.com/forum/index.php?topic=2112.210, page 13 or 14 phila_dot posts below which is also listed in the wiki as "may work". Then there is a file on page 15 that im unsure if something was changed on a higher level in the programming, where the example below looks to be some sort of variable reference replacement. Whatever was done in that file seemed to have worked, but the thread jumped to blow through maf discussion and didnt go into much detail about the single 02.

If phila or someone could chime in thatd be great!



Define these as 16 bit (do not designate LoHi or LSB), output type will be Hex digits.

To delete B1:
0x3C8BE
0x3C8D0
0x3E832

Original value will be 1A91, to replace with B2 input change to 1891.

To delete B2:
0x3C8F0
0x3C902
0x3EA90

Original value will be 1891, to replace with B1 input change to 1A91.

I can explain more later if you would like, but no time now.

I don't think that the final working version was ever posted.

I can send it your way once I get back from the shore this weekend.

Yeah, if you just do what is listed, then trims will oscillate wildly.

You're also going to want to change:

0x89B08 to AE28 for sw 0001

or

0x89B12 to AE28 for sw 0002

Note: I use Bank2!

What would these values change to if using bank 1?

Had all these settings for b2s1 as primary and only sensor. Fuel trims stayed same for a long time. Took a few 300 mile trips and partial trims worked their way to +25 and -25. Will continue to monitor.
