Ecu Remap Report

[raymac]

Maybe I am a cynic, but I fail to see how the performance of a vehicle with a remapped engine, even if it is to 165bhp, is so much faster than the model with the standard 204bhp engine. Laws of physics and all that.

 

Mr T i might be wrong :D (i usally am :27: ) but i don't think remapping 115 bhp to 150bhp (i think thats the general consensus on a 115 remap) makes the car go faster top end it just gets you to the top end a lot quicker :( i hope that is as clear to you as it is to me :D :P :D

The torque is the issue. Torque and BHP are not the same thing, although they are related.

Well, the story so far, I've been over today and there was a problem getting the computer to link to the ECU through the usual port under the dash, so the ECU had to come out and be plugged in direct. To get the ECU out though, the battery has to be removed and there is a bracket holding it in place, so using a torq screwdriver to undo the screw at the bottom it needs to be taken off, then a couple of clips hold it place. Once off and powered up it connects no problem to the computer for remapping. This contains all the information required for remapping, the software ID and hardware ID are all located on the ECU sticker externally, however the rest of the info is read into the laptop.

It was not possible to do the remap there and then as he didn't have any of the remaps for this vehicle, and a colleague of his does them, so it'll be another trip over or him come to me for the remap now he has all the info required, you go through what you want in the way of torque, bhp, driving characteristics, mpg etc then does a custom remap to your own requirements.

Hopefully by tomorrow or end of the week I will have had it done. Hes done loads before, mainly Golfs, Leons etc. VW PD mainly specialises in. He can do this price for anyone prepared to travel to him.

The torque is the issue. Torque and BHP are not the same thing, although they are related.

 

The rate of acceleration is decided by power rather than by torque. It takes approximately 600KJ of energy to accelerate the mass of an unladen Galaxy to 60mph (there is additionally the work to overcome all the rolling friction and the air resistance which is a far more complicated calculation).

 

Power is the rate at which you energy is used, so to get ther mass of a Galaxy to 60mph in 10 secs (without friction) requires 600KJ/10s = 60KJ/s or 60KW (80hp) average power over that time. Double the power, half the acceleration time.

 

With resistance it will take over double the power calculated above to reach 60mph in the same time.

 

Additionally it is the average power shown above, as conventional engines and gearboxes cannot run the engine constantly at maximum power whilst accelerating. Diesels will usually produce a slightly higher average power across the rpm range as a proportion of their maximum power than petrol engines due to their flatter torque curve.

WOW ! Get it done, its got so much more torque in every gear, low down pulling power and loads more pull throughout the rev range. Guy came to me in the end and removed ECU, flashing it with the new software. The difference is greater than I ever imagined, it must have knocked seconds off the 0-60 time. It is now around the 150bhp (115bhp before) mark, drive it steady and by having the low down power it will return about the same MPG, drive it hard and you will notice a difference in MPG, after all you don't get something for nothing ! I would definately recommend it though, just coming up hills on the way home it was in a lower gear than before. It puts the power to the ground perfect, with no wheel spin, it can be pushed further but its not recommended, after all they do a 150bhp Galaxy now. A happy customer. :unsure:

...MrT, are you quite certain of your kinematics?

 

Acceleration is really only affected by changes in an engines torque characteristics, more Power will give more top speed. How can you argue about this?

[jkspoff]

Try out www.chipboost.com or www.angeltuning.com for remapping. I used the first link.

I find the Gals performance to be staggering compared to what it was, but it can be driven exactly as before, the accelerator is not twitchy, however if you are a bit too heavy on the pedal the turbo does come in earlier. The fuel economy is about the same on normal driving, but as I mentioned above you can make a large dent in the fuel economy by booting it everywhere which is tempting to start with, until the novelty wears off ! After a few days of driving it, you find that slightly less pressure on the pedal can make the car perform and drive exactly as before the remap with no effort. I got a moderate rather than extreme remap, to make it easier and cheaper to live with on a daily basis.

 

The same remap I have is now stored on the guys laptop, so if you decided you wanted the same version then it could be loaded and adapted to your ECU also.

...also acceleration rate change... Engineers call it 'Jerk'. <_<

 

That's why petrol engined cars, for the same brake horse power, accelerate quicker than diesels. However, this is true only if you rev the nuts off them. Turbo petrol engines are always quicker than either.

IMHO it's the turbo that's king, not the petrol or the diesel.

Hi folks

 

i've been in touch with chipboost.com and the guy there, James, will do the remap for

What difference has it made to your insurance costs?

 

Fancy a bit more power but not if it is going to make life difficult

jkspoff - i'll be gald to tell him you are happy but i suspect he doesn't know anyone by the name of jkspoff!

 

if you want to share you're name i'll pass on your gratitude

 

I appear to have a similar motor to yours mate, 2001 state blue (albeit Zetec) 1.9 115 bhp with 52k on the clock

 

your remap sounds just the business, plenty of grunt and torque but remaining easy to drive - think i'll go for that

 

cheers mate

Hi all. Does anybody know where i can get a good remap done in the south west. Have been reading all the coments on here and am starting to get the erge. The one in Scarborough sounds fab but its too far for me to travel. Had a quote from one local tuning company who uses an independant company to do their remaps but they would like to relieve me of over

Hi, it was the first Galaxy he had done, so he'll which one it is, my name is James. My remap is very easy to live with, same as before if you want it to be by being less harsh on the accelerator or grunt and torque if you push harder.

It is well worth

They recon on upto 45bhp difference - making a potential 115bhp into 160bhp, but I recon it would be be nearer 35bhp without changing air filter and pushing the remap/engine to the limit. I would like to rolling road test it to find out, but I'd feel a bit daft pulling up at my local boy racers garage in a people carrier for a rolling road test ! :(

 

Adrianf, just promise the wife a trip to the North Yorkshire sea side town of Scarborough with a 30 minute stop off on the way, make a night of it and stop off at the Wrea Head hotel, its very nice there, or there are plenty of caravan sites around there.

MMMM i understand what you are saying but 2 moaning kids in the back all the way to yorkshire and back. All of a sudden 115bhp sounds ample. I think ill keep looking for a closer one, theres got to be one just a case of finding it..

[mike99]

do you know if this can be done to a 2001 115bhp tiptronic auto??

Not sure if the box is made for the extra power

No conversion needed for Biodiesel & it will mix with Crude Oil Diesel, only straight Veg Oil needs a separate tank

No Loss on power, I noticed smoother & quieter running & the same MPG

The only problem I've noticed is during the winter months when its best to run a 75% mix with crude oil Diesel as it solidifies

 

 

The other problem is supply as only a few places do a 100% mix, such as ID Oils in York & Sunside in Halifax

All Rix & Petrolplus filling stations have 5% mix

Unless you want to spend a few grand & buy the equipment

remap update!

 

just got back from sunny Scarborough, where James at Chipboost remapped my 115tdi - probably nopw up to around 145 - 150 bhp and it drives absolutely beautifully

 

it's a very smooth drive, but the Gal is more responsive and just eats up those hills in high gear

 

for anyone that knows Staxton hill, the Gal flew up there in 4th and was eager to go into 5th (this is a very steep hill ordinarilly requiring a drop doen into third to get to the top)

 

whiilst the car is quiicker upto 60, it's between 60 and 90 where you notice the differecne - the thing is jsut eager to acceleerate in 6th with all the increased torque

 

i've had mine done because i tow a large caravan - can't wait to see what difference it makes to that

 

I'd agreed a price of
