Many different names for the same things - some cars have a cable running from the alt's negative to the chassis, some bolt to the engine which is wired to the chassis, some bolt to engine or chassis directly etc.
You end up with a load of gash looking cables under your bonnet, a wasted afternoon and (probably negligible) bit of extra weight.
I can understand upgrading cabling if you upgrade the load - but I can't see OEM's intentionally using cabling far too small for the standard car - plus the normally quoted "benefits" are about sensors "working better", which I can't really see either...
"The big three" consists of the alt's ground, and the batteries ground (and also the alt postive)
I've got loads of 4AWG (and even 2x5M 0AWG runs) spare... but I just can't see a point using it.
I can understand that if you put more load on the vehicles electrical system, you might want to upgrade the batteries earth (i.e. a large ICE install)... but all the "reviews" I can find are all of virtually standard cars, and all seem to claim that somehow it makes the car more "responsive" or "shift better"...
The crazy thing is, these things sell for ~£60? For a few metres of 8+ AWG wire?
Engine was designed to produce ~115 HP, with an engine which originally produced ~170 HP (with a different turbo), as that was the original performance they were aiming for (i.e. well below any BMW)
When BMW quit, MGR did some testing and found they could easily get is to produce ~135 HP, with nothing more than an ECU map. They sold the two models concurrently for a while, while offering the "XPower Upgrade" to existing owners, and then only sold the 135 model.
BMW / VAG do similar with their diesels afaik.
EDIT - It wasn't originally mapped "badly", they simply weren't after a lot of power. Tax rates were unaffected, although tbh there wasn't such a focus on this / company car bands 10 years ago. MPG was also largely unaffected, as 115 HP was a little low for such a lardy car, so having a little more power didn't make much of a difference.
I'm sorry, but he wasn't trying.
I'm not saying this applies here, but remember many manufacturers use the same engine on many cars, making a cold, "warm" and "hot" variant different with nothing but the map
Not something I've ever heard of before (although I've not done one before I must admit).
They offer tuition, but it's not mandatory. But if you treat it as a race / drive like a knob, you probably will be black flagged.
EDIT - are you looking at a "proper" trackday, or one of the driving experiences? The latter will mandate an instructor because it's their car, not yours (and often it's not even theirs, it's rented from the owner).
I wouldn't think so - it would depend on the gearing, powerband of the engine, cam profile, and if the resistance is static or dynamic - air resistance increases exponentially wrt speed whereas I'd guess tyres rolling resistance would increase linearly.
EDIT - 51 MPG? From a 1.3 MK2 Golf?! Doesn't sound quite right to me...
How is not using WiFi going to help (i'm not on WiFi, but even if I was i'd still be on the same network)?
A new router isn't really an option - it's not "my" network
Firewall off on both routers, DMZ on the TP Link to the Xbox, but the DMZ on the BT HomeHub doesn't work (it ONLY gives you an incomprehensible list of devices, you can't specify an IP - it's a mix of random names and MAC addresses and I can't find either device on the list).
