BW Chiptune - after 2000 miles

Post by Dizeee »

In case it was missed, in the main forum.

Had the most amazing luck -a friend has a long private driveway. He is called John.

John let me kick down on his land, just before the public road. So I pressed the throttle, on my BW tuned engine. Kids laughed, engine sang, and I just sat back and enjoyed the inertia.

The car is stock, fully stock.. Just a map by Jason at BW. I had my car mapped in May 2020. I have done some miles since - and some of those have been tasty - very hard driving with some exertion on the engine.

Not a whisper of complaint so far from the car - strong and true. Took it to Surrey RR this month - graph speaks for itself.

How does the print out compare to BW print out? Are you still on the standard charge pipe?

Well, SRR was only 3 bhp above Jasons, which read 427. Jason seemed surprised by this, but as I said to him, I bowled over there and the car did 2 runs in quick succession and that was it. There were no repeated runs between cool down, so I think potentially could have made a tiny bit more with a bit of effort. But I am really not fussed at all.

Everything is stock on the car.

When Jason did mine he recommended changing the charge pipe , which I got them to do. It’s quite common for them to blow off when you up the power 👍

B58 charge pipes are fine.

Oh I think it's the n55 ones that are prone to splitting. Read a few posts in here about it
