What makes the Mercedes-Benz SLK R170 special
Mercedes SLK R170 remap: the V6 and the Kompressor side by side
On the R170, the SLK 320 and the SLK 230 Kompressor take completely different routes to their power. A 3.2-litre V6 gives the 320 its 218 hp and 310 Nm; the 230 Kompressor relies on a supercharger for 197 hp. The V6 SLK 320 came with the facelift of February 2000, and the R170 ran from 1996 until the R171 took over in spring 2004. In Britain it is simply the Mercedes SLK, with R170 as its generation, and the petrol badges were SLK 200 Kompressor, 230 Kompressor, 320 and 32 AMG. In the catalogue the R170 has just one engine, the naturally aspirated SLK 320, which takes the GAN GA+. The GAN GA+ takes it from 218 hp and 310 Nm to 244 hp and 347 Nm.
Treat both as catalogue figures for the engine type; neither is a dyno measurement of your own car. On a naturally aspirated V6 such as this the GAN GA+ is rated for up to 12% more power. On the M112 V6 the recurring faults are leaking camshaft covers and failed crankshaft-position sensors, so check both before you add power. The folding hard top and its window mechanism need a look too, though a tuning box touches neither. If you want the R171, SLK 350 or SLK 400, that is the next generation.
Mercedes-Benz SLK R170 remap: common questions
Where are the SLK 200 Kompressor and SLK 230 Kompressor in the catalogue?
The SLK 230 Kompressor has its row on the Mercedes SLK R171 page. The SLK 200 Kompressor has no separate R170 row: the same engine is listed as the 200 Kompressor 2.0 of the Mercedes C-Class W203.
How much does the GAN GA+ add to the SLK 320?
On the SLK 320 the catalogue gain comes to 26 hp and 37 Nm. Fitting uses only the existing connectors, removal takes about a minute, and nothing is written to the ECU.
Mercedes SLK R170 remap or tuning box?
A flash remap replaces the ECU's factory software; a tuning box leaves that software as it is. The ECU software is never changed and the box can come off at any time, so your manufacturer's warranty is preserved.
Does a GAN tuning box affect my car insurance?
Yes. In the UK a power increase counts as a modification, and insurers expect to be told about it before you drive with the box fitted. Each insurer handles it differently, so check with yours first and quote the before-and-after output from the table above.
Is a tuning module the same as a Stage 1 remap?
Not quite. Stage 1 usually means an ECU remap without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
