MAF Cliping with Turbo Kit

[changchewsoon]

Giupo,

I'm currently using the E-Manage Blue for my turbo, and the MAF volt is clamped at 4.95v.

Do you have a MAP sensor as well? If budget permits, you may want to add a MAP sensor as another input for your Ultimate and tune your car off its reading as well. You can achieve a much more accurate tune with a MAP sensor rather than relying on the TPS readings. But in your case, you have the boost harness as well, which is cool.

If you don't want to go standalone but yet you want to remove the MAF altogether, you could consider using the HKS F-CON V Pro. It allows you to remove the MAF physically.
