The basic software to tune these cars is all the same. It lays in which Hardware and tuner you use that makes the difference.

The biggest thing with our cars is they are not like any other 3.2L MB has offered. I say this because the fuel injectors are a completely different size. Most tuning companies copy the tuning file from the SLK and assume it will work well on the Crossfire, but the Crossfire has 17lbs/hr vs. 19 lbs/hr for the SLK. I recall one company selling these tunes and not even knowing where the ECU was in the Crossfire. I suspect they were using a SLK file.

If you take already overtaxed injectors and try to squeeze more fuel out of them equal to a 19lbs/hr set up you will get subpar results.

We've worked with our tuners and with numerous A/F Dyno runs finally came up with a tune that will work much better for our cars.

That is the biggest difference. We are dedicated to exracting the HP out of the Crossfire not dynoing a SLK and hoping we get the same results.

So if you want a generic tune for the 3.2L motor go for it, but if you want a tune for the Crossfire we'll pencil you in for an appointment.
