RR problem

[Harrismarine]

I did a base tune with my RR and then flashed the saved tune into the boats 411 pcm and had to increase the numbers in the VE table by around 30% to stop the motor running super lean, I compared the two tunes before I changed the VE and they are the same......put it back on the roadrunner and all is good, any Idea whats going on?

Are you viewing the VE in [%] units...? If so, is the displacement parameter different between the 2 tunes...?


Also, sanity check: are you sure you saved the file...?

Hi Joecar, I have been back through it and if I put the roadrunner back on it runs fine with the tune (that I saved) in the RR, But flash that tune into the 411 and it runs lean

The tune that you flash into the 411, read it back and compare with what you flashed in.
