Buick Regal ECU remapping
21 files available
About remapping
The Buick Regal accounts for 21 files in our catalogue, entirely petrol: the 2.0i naturally aspirated leads, with the 2.0 Turbo and 1.6 Turbo alongside and a 2.4i also present. It is a mid-size saloon sharing its platform with the Opel Insignia.
Stage 1 accounts for 20 of the 21 files — a very clean profile — with one pop and bang. The ECUs are the group's references: E37, E39, E83, ME9 and Delco units.

Which engine gains most?
The 2.0 Turbo, by a clear margin. The naturally aspirated 2.0i and 2.4i gain considerably less, since there is no boost to adjust.
Is it the same as the Opel Insignia?
They share platform and much of their engine range, sold under different brands. Our experience with one applies largely to the other.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
