159 2.4JTDm Alfamen remap
« on: May 02, 2021, 02:37:54 PM »
Documentation for an 159 2.4JTDm says it has been remapped by Alfamen in Melbourne. It says it is a stage 3 remap, but doesn't state any other information. Alfamen seems to have closed their doors unfortunately, so I can't ask them.
Does anybody know what they would have done?

Removed the regeneration exhaust box and put in a straight through pipe.

Closed off the EGR so that oil is not put back into the inlet manifold. Should see less turbo lag as a result.

Possibly kept the swirl flaps open.

Running on a richer mixture that gives more grunt on the same throttle at the expense of slightly hotter  temp.  The gear box and coolant system should be able to cope.

I had a stage 3 DPF delete and remap done and it made a huge improvement to driveability and fuel economy. Beware though that your insurance company won't like it.
