The line at the bottom in blue is the run i did at r/r day with the old code
The line at the bottom in the red is the new code.
That is a truly awful map.
You will get 1 initial push in the back and that is it. Think about it, you accelerate in 2nd say, change up at 6500rpm, revs drop down to 5000rpm and then you accelerate in 3rd between 5000-6500, change up at 6500rpm and then revs drop down to 5000rpm in 4th and accelerate the same 5000-6500 and so on and on. At no point bar that 1st little burst of acceleration that you are getting to exploit that peak torque figure.
That 3000rpm
spike is just utterly pointless, the torque of your car is nowhere near a genuine 350lbft+. It's even more pointless as it's just going to lose traction in 2nd, possibly 3rd so it's wasted. The tuner should control boost better and sustain that torque over a wider range. This literally peaks and then falls off a cliff.
I would take any results from awesomes dynojet with a pinch of salt too.
As to different maps, well a revo map may well have a peak torque figure of 350lbft vs say a custom code of 300lbft but do not be fooled into thinking the 350lbft car is quicker.If anything it will be the
lower more sustained custom code map due to the reasoning explained with shift points above. Custom code sofware will hold on and sustain more torque further up which will make an overall faster car. You really do need to compare torque at 5000rpm+ to determine how quick your car is going to be against another through the gears.
Its just a characteristic of these turbos, awesome GTI led me to believe I produced 420lbft from the 1.8T when i activated nitrous. Again, this was a massive peak followed by a sharp drop as exhaust manifold could not flow the air quick enough and boost and torque fell off a cliff.
Let's see what happens when you go full throttle 2nd gear at 20mph all the way upto 100mph+.....
Turbo spools and comes on boost, you see a big spike on your boost gauge (If you have 1) and between 2750-4000rpm you produce 300lbft+. If the tyres put this down onto the tarmac, its going to give you a good push in the back and the car is going to feel strong, but I suspect you will see some form of ESP flicker meaning a lot of this is going to be wasted effort. In anycase you have only been accelerating for 2secs or so (2750-4000) and you continue to 6500rpm where you change into 3rd. Revs drop down to 5000rpm and just look at your map now. Car is not producing anywhere near 350lbft, at 5000rpm where your shift point in each gear drops down to, you are producing 270lbft at 5000rpm, 240lbft at 5500rpm, 230lbft at 6000rpm and then 205lbft at 6500rpm where you change up.
Revs fall back to 5000rpm and you accelerate again, 270lbft down to 205lbft between 5000-6500 and then you change up to the next gear. The headline 350lbft is nowhere to be seen bar the initial 2secs or so of first press of the pedal all that time ago now in 2nd gear.
For a quick through the gears car guys, concentrate on the figures in that 5000rpm+ region as that is where you will be spending 99% of your time accelerating
The only benefit I see from this initial peak torque in a drag race would be accelerating from low down in 6th, say 45mph in 6th. Okay if the other car your racing is in 6th too but he will most likely drop a couple of cogs and get down into 4th, you're forced to do the same to keep up and this spike in torque low down is then wasted at your shift points.
Make sense?
