• Before and after results of an Evolve Automotive tune on a VF-Engineering VF570 supercharged E46 M3 - +35 wheel horsepower

      Evolve get a good amount of business from customers running forced induction kits from tuners that compete with them. The cool thing about Evolve is that does not bother them as they will still tune it for you unlike many other tuners and it does not matter what platform it is or if it happens to be one they directly compete in. Evolve simply will do a custom tune just as someone asks and that is how it should be as in reality the hardware and engine belong to the owner of said car, right?

      In SAE correction on a dynojet the VF570 kit put down a respectable 450 wheel horsepower at 9 psi with Evosport headers and an exhaust system. The issue with many of these supercharger kits is that they are a one size fits all but not call motors are equal. Break in, fuel, how it is driven, elevation, etc., all affect it. Apparently the default VF tune which comes with the kit on this particular car was running a bit too rich.

      How rich? Well, apparently quite a bit on the rich side as look at those gains through the curve. It would be nice to see the air/fuel graph not blocked out but that might open up a can of worms and create friction between the two companies. Regardless, the owner said he is happy and that he now understand why the fuel tank would empty so quickly with the VF tune. Nice work by [email]Sal@evolve .

      Graph is below.

        Evolve is putting in work, great job.

        That's extremely impressive... For the cost of a tune - the power Evolve extracted is no joke. It's crazy - if you look at the graph (around 7100 RPM) - the HP line has the same shape (see the little dips - they just move up) as before, just shifted up. That's cool.

        AFR?

        thats a pretty nice power curve and great increase on the upper end. can you share any detail on the improved gas mileage? for example, with a similar setup, my car gets about 200 miles on a full tank of 91 octane with spirited driving.

        The owner has to drive the car with the new tune to compare the miles per tank.

        love it. Nice work. I will probably go with an Evolve tune down the road on my VF540 E93.

        Thanks for the insight Click here to enlarge I was hoping to have the owner of the tuned M3 chime in instead of triangulating through the moderator of this forum. In any case, I see the owner has posted a similar thread on a different forum so i will revert to that forum for direct follow up.

        Did they both maintain same psi? At least show a boost if not AFR. That's great gain for just a retune LOL.

        Good point on the boost.

        From Evolve:

        Please
        ignore the stoichometric running at low rpm. This is where the DME goes from
        closed to open loop and the AFR catches up. If we measure AFR closer to the
        headers it looks very different.
        The AFR also goes momentarily rich but
        again, this is just to do with catching up of the integrators.
        High rpm we
        run around 12.8 AFR and because we are running such low ignition targets (16-18
        degrees Maximum) the exhaust gas temperatures are nice and low. There is no need
        to run much more rich than this.

        I am sure someone will say it's all too
        lean :-)

        what makes evolve qualified to tune for other companies supercharger kits? wouldnt the company who developed the kit know how to tune it right the first time? Serious question not being a troll/smart a$$ I genuinely want to know.

        They may not have the best reputation but it seems like a fair amount of people are happy with their vf kit. Also what about ess evolve seems to have re tuned a few of their kits too?

        True, not all kits from VF have had problems. I'm not sure how many, if I recall LM had that done. I'm not sure though. I think he said it wasn't as smooth as it could have been etc.

        What makes someone putting hardware together qualified to tune? You may not know this but VF had some issues with their S54 setups.

        There's nothing wrong with their kit but that doesn't mean a tuner who knows the motor better can't get more out of it.

        I was just asking a genuin question your, jimmies seem to be rustled. But to answer your question I just figured developing a kit is more than just hardware and a one size fits all type of tune. To me part of developing a kit would also knowing how to properly tune an engine to operate at full efficiency.
