Thanks for that
Yes it is 48.4 highway, not combined. In the UK we refer to that as extra-urban :P
I did sit behind a big square truck for a fair while but after he left the tanker was the next best thing. Weren't as many around on the road as I'd hoped for lol.
After reading about my engine management system it appears the injectors are always live and the ECU pulses the injectors to earth to trigger them. Could I therefore have them on a switch inside the car that I can activate to connect the injectors directly to battery live so as to effectively disable them?
Then on a glide I could flick the switch to effectively stop any fuel from being injected but keep all electronics going, then turn the injectors back on again for the next pulse.
Eventually I would work to automate this somehow, but would this work for the moment? Also should I be aiming to do 50-60 rather than 50-70mph? Thanks!
