Cyl Fuel Trim

[Nuno_Cristiano]

Hello,

I have some curiosity in knowing if they use some fuel trim in cylinder 5 and 4 with Wagner intake manifold (inverted).

For example:

5cyl: + 6%

4cyl: + 4%

3cyl: + 2%

2cyl: 0

1cyl: 0

Ask it because i use only 1 EGT sensor in preturbo and notice sparks 5 and 4 a bit leaner. AFR total measure by wide-band run at 0.80 seems perfect.

without per cylinder EGT or better per cylinder lambda its only guessing

Yes it´s true but i´m looking who had this experience with Wagner Intake Manifold.
