Title: SEPST: Can I use 044 speed density cal with 2008 ECM instead of 205 alpha-N
Post by: jty on August 02, 2019, 11:49:09 PM
Application: 2008 Touring with 120R engine, Tman 660-SM cams, SE 58mm TB w/SE HB Elite, Khromewerks 2:1:2 exhaust.

My current tune is based on 205UF006 but I recently realised that the 044SDO209A calibration has my ECM PN listed as fitment but its application
is listed as 2010-2013 Touring.

Is it possible to switch to the new speed density software level (and retune)?

I would say no, because the 10-13 cal is looking for the small 02 sensors, which have a different voltage bias.

Ok, too bad. Thanks a bunch for the help! Best forum.

What are you tuning with, I believe I have the MAP VS RPM cals in PV for 08-09

stock '09 cal is speed density, software level 218

Sorry for the delay, not daily here.  I'm tuning with SEPST.

Yes, and SEPST offers speed density cal for 2009 on. I did not remember they changed the lambdas and moved them further down with the new frame.
