Re mapping

TBH, I was thinking just 5% plus would be fine

My apologies if I’m being thick. Your looking for a 5% Power increase on 140hp?

yes.

 

[Wellytrack]

yes.

7 horsepower?

 

[czechmate]

7 horsepower?

yes. But it’s all extra. Ie the tractor and mower hasn’t got any heavier at all.
From competition use, esp with 1600, i know there is a big difference between 150 hp to160.
Or, for example taking a blast down the road solo, then carrying a passenger/Co driver. You wouldn’t think 80 kg extra on a tonne would notice, but…

From your rallying background that kind of thinking is 100% correct small weight savings all add up, hence some special edition off the shelf performance cars had carbon fibre replacing bonnets and boots and plastic replacing glass, however in this example it’s a slow speed and constant load, I believe unless your coming at your Deutz with 15% (21hp) you won’t find much difference.

Interesting. I’ll have the conversation with the man on Wednesday

I expect the bill will be the same regardless of the increase and if it turns out to be not enough you'll be charged twice

the bill is 1.2k.
But fuel is so close to €1/lt now

It always interests me when people say they have chipped the tractor or whatever to give more power and it's using less fuel. The laws of thermodynamics thrown out of the window....

If you keep messing with the emissions controls, chipping them out or whatever, there will come a time when legislation catches up and you and the person supplying the chip will get prosecuted, it happened in the USA.

I used to know someone who calibrated engines to get them through the emissions regs for a leading OEM car manufacturer. I asked him about chips and aftermarket add ones. He just rolled his eyes and said if you want to waste your money buy one.

It would be interesting to see the testing the chip suppliers do, I'd be very surprised to see if they involved a dyno.

I assume the fuel savings they quote are from having enough power to travel faster and cover more ground per litre rather than just drinking less?

they say just drinking less

I don't know if it was a steinbauer agent or the firm themselves but their airbrushed,sign written van was towing a Dyno past here last week

They are using a dyno

I remember one firm saying that it would drink more per hour but the workrate increased by more. Their example was a 4 metre power harrow instead of a 3 so 33% better off. Not sure it's quite as simple

i have spent many hours (awful hours, I hate it) with petrol engine rally cars on rolling roads. Both mapping modern engines and jetting carbs. They have to measure the CO for engine safety and they always get to the point of incredible power by running lean (so I assume using less fuel per power unit - not measured on a rally car ) but in that instance, it can’t be left that way as the quick result will be melted pistons

Same thing tuning a chainsaw,leaner the mix,the higher the rev, until the bang

yea, that last bit of fuel out the tank, you’ve suddenly got a turbo saw

Just when you're thinking " Christ this saw is running well" 🫣

 

[Lakesdigger]

Even the biggest tractor in one range may be running the same engine as the smaller tractors in the range above (NH t6 6 pot motor is used right up to the bigger t7's so in theory there's loads of power to be had from a t6 but the transmission won't agree). Another thing is that manufacturers ECU software is mapped to suit a wide and varying fuel quality and often worldwide climate conditions. That's where a proper mapper can get the gains from optimising the ECU settings.
Chipping or flash maps are usually just lumping more fuel and air in with little finesse.

i had a bsa motorbike back in the late sixties which melted it's piston by running too lean. when it was rebuilt it got a main jet 1 size bigger, didn't go as well though.
