Tune 11919


It is from an '09 Saab 9-7X AERO. For some reason this OS just does not like to take the usual tuning tweaks that previous '07-08 TBSS's like. No matter what, when you go WOT from idle it triggers an ECM Internal Failure and goes into limp mode. Can you more experienced guys see anything, possibly an unlocked spark or fuel parameter, that may be causing it?

Is this the stock file, could it have been modified before you read it?

Is this giving you trouble in a Saab or with the LS2 in your TBSS? And is the tune you posted the one read out of one of these vehicles or is it from the EFILive tune file tune depot?

It runs fine in the Saab. The thing is when you put a TBSS in a Saab the aforementioned drive condition occurs. Conversely, when you put this Saab cal in a TBSS, same condition occurs. Having spent several months adjusting PE, spark, knock, misfire, and fuel (which does change and improve driveability) is leading me to think that there are some extra tables for '09 E67's that are not being given to us.

You swapping ECM's or just calibrations? And are the throttle bodies the same? And what extra tables would be missing?

Not sure...I'm thinking for '09 they may have gone with a different TB...maybe that infamous 'gold' blade. Maybe that's the problem.

Nothing wrong with the gold blade :) Just needs the right ETC cal.

Were you swapping tunes or whole ECM's? i.e. SAAB tune into TBSS ECM?
