TDI Tuning for beginners

[slick]

Mine dropped but then as Uncle fester has suggested, when remapped its alot more fun and fun means less MPG.. plus i have quite extendly modifed the wheels, suspension and drive systems on my leon and lost abit of MPG dues to extra on the wheels and etc..
Soon i will be heading the same way as Devonmikey and down to allards for a upgrade in power around 260-280 mark will be what i'll be after, the i expect MPG to be down a little more unless i adopt granny driving, but why spend all that money on upgrades and then not use the full use of those upgrades!

mate if you spend all that money, you dnt wanna be a granny! i want mine to be a bit quicker and not make a great great loss in mpg + not got tht kinda money @ the mo

what does resetting the ecu actually do? also what are these green cotton filters?

 

[sssstew]

the ECU 'learns' so resetting the ecu means it has to relearn all its adaption values, some people have had good results with this, others noticed no difference after it had re-learnt.

green cotton filters are a brand of Air Fliter that are relativly MAF (Mass Air Flow meter) friendly, MAFs tend to die alot on VAG engines, usually due to either dodgy parts or getting oily.

 

[woodyTDI]

Stew, i am very new to TDI's what is the MAF? does resetting the ecu actually loose any info?

 

[sssstew]

its the Mass Air Flow meter, as mentioned above, its the sensor just after the air box.
The task of the air-mass flow meter is to measure the fresh air mass supplied to the engine. This fresh air mass is used to calculate the exhaust gas recirculation rate and the permissible injection quantity.

restting the ECU looses no important information, only the learnt values which the ecu will relearn.

How friendly are the insurance companies when you declare all the mods ?

How comes remaping is so expensive. i dunno if its just me but 30mins reprogramming a chip for £425 seems alot of money for very little work.

I would estimate the cost is made up of:

R&D
Cost recovery - cost of kit / software / time, etc
Profit

still seems alot unless the software manufactures take a cut each time someone uses it like with phone unlocking software.


ah well price we pay is the price we pay i guess.

 

[woodyTDI]

I know what you mean! would be great if you knew someone im sure a few lucky people do!

 

[Nutkin]

maybe if we were to organise a whole lot of people to one place maybe a discount? cause i want the fuly switchable one.

 

[woodyTDI]

Yes i would want a switchable one too. But we are all over the country? maybe organise two for the south and north or something? but who would we talk too and whats the likelyhood off it?

 

[thebeno]

Likelyhood, none.

Or you can go to Pete at Bells in York, and have change from 300 notes, thats where Im off, great write ups!!

What are the figures you get from there? in bhp? also is it switchable?

 

[markmck]

there's a guy over on TDIclub does a tuning kit with a flasher and custom maps

can't find the link just now but i'll see if I can dig it out
