Mapping Time
This has been taken from EarLs website dedicated to his car : http://www.red-beast.co.uk/ - I think it's a little piece of genius, and shows what a difference a decent map can make to a car.
The Beast is finally running on it's inital map that was set up by Dave Rowe of MoTeC, yesterday evening.
The session was scheduled for around 5.30pm, but as Dave was not that busy, and I had managed to get there early, we started setting up at around 4.45pm.
The lambda sensor was connected, along with the knock sensor and boost controller pipework, and Dave made a few adjustments to the ECU's pin outs themselves. Once this had been done, we got into the car, and Dave connected up his laptop...
He initially updated the ECU's firmware, so that it was up to date. Once that had been done, he quickly looked at the base map that Andi had set up for running the motor in, and made a few modifications to both the fuelling, and the ignition maps.
He then asked for me to start the car, so that he could adjust the idle A/F ratio and ignition curve. He then set two self imposed rev limiters. The first for cold weather starting, where for fifteen minutes, the car cannot be revved above 3000 rpm, and the other as an engine temperature limit. He set that to 110 degrees, and the rev limit to 2000 rpm. Once that was done, we set off for the session in earnest.
Out onto the road, and up to the motorway, and Dave was beavering away, making adjustments to smooth out both the fueling and ignition, and as he was doing so, the car just came alive!
We followed the traffic, and headed for Northampton.
As the traffic cleared, and the road straightened out, Dave gave the go ahead to bury the pedal. I did as he suggested....
...and nearly laid an egg!!!
The car accellerated so hard, it took my breath away! It hurt! I can honestly say, I was gobsmacked by the ferocity of how this thing makes power.
Dave suggested we head towards a road that leads up towards the Silverstone race circuit, as this is long and straight, and normally pretty clear of traffic.
As we approached, the road swept round to the left in a faily long arc, then dipped and came back up onto the main straight. As we did, I buried it in third. By this time Dave was well into controlling the boost, and had made good inroads into sorting the fuelling and ingition. The car took off like a rocket.
4th gear and it still felt like it was trying to lift the front wheels! I've never felt such a rush in my life! At this point, Dave gestured to coast, so that he could make a few adjustments to the surrounding load cells, so that it pulled a little cleaner.
We pulled into a petrol station to refil, as I had used a quarter of a tank, and needed to refil for the journey back home to Cardiff. He checked through the various data to see how the car was performing, and when I got back from paying for the fuel, he ran me through some of the data.
The car hadn't even broken into a sweat! Inlet temps hadn't risen above 34 degrees (although it was a pretty cold evening), and he said there was lots to come, as he hadn't increased the boost to more than 1.2 bar!!! Even he had to admit, this thing was mightily impressive. All credit to Andi Martin for that, I told him, to which he agreed, wholeheartedly.
We headed back out onto the road, and Dave made a few adjustments to the boost, and said we'd be going for around 1.5 bar, and he wanted me to give it 100% throttle in all gears, so that he could finalise the map.
We headed back out to the long road, and I slowed as we came to the adjoining roundabout. Dave put his det cans back on and we went for it. Holy crap! It felt like Godzilla had just punched me in the chest! Both of us were giggling like a pair of school kids as the car shot forward like a scolded cat! Nothing at all on the road, and it was as striaght as an arrow for miles. What a feeling. I daren't even glance down at the speedo to see what we were doing, but Dave just sat there, totally unphased by the whole experience, other than a wry smile in his face. Fifth gear and It still wanted to tear my face off! Dave motioned to coast, and said that we should finish for tonight, as most of the map was complete. He removed his det cans and asked me to give it some stick in third and fourth, to which I obliged. This time, he was just along for the ride.
As Dave had been mapping, and had been wearing his cans, he hadn't heard the ruckass that was going on in the cabin. The sound of this thing when it's been given it's head is unbelievable.
I'll leave it to Dave Rowe to describe it...
"Woah! This thing rocks!"
The man's a genius.
