Boring TDI: remapping and vegging

[vaughant]

How old is your 110 TDI? There's a relatively narrow window of model years that allow for a plug and play remap at home.

Y, 2001 same as yours but Leon variety.

 

Deffo has an ECU as it threw a few fault lights up now and again until I cleaned all the electrical connectors.

Should be good to go then. All VW TDIs have ECUs but not all of them can have new maps written onto them easily.

How about for example a 1999 passat 1.9 tdi?

[Lacquer Peel]

I think that's slightly too old.

Blacksmoke sell cheap remap files that simply require flashing across your ECU, they seem to be well thought of but it's important to check your ECU number as well as engine code for compatibility.

 

110 (ASV or AHF)

90 (ALH or AGR)

Unfortunately none for the 110 Passat (AFN or AVG) but lots for the more tradional transverse TDi stuff.

Worth remembering when running high veg% that it's the speed at which the fuel can pass through the filter and down the lines from the tank which limits GLF-ability.

 

Warm weather is great for no-mods-veg, tweak the computer bits for even more driveshaft wobbles but the first cool morning in September will feel like limp-limp mode.

 

That generation of VAG have restrictive sender units, it's worth poking out the 1-way valve on the supply line. Increasing the supply line size also makes it feel like the turbo has grown, especially when you can warm the fuel up a bit to slide through the filter faster.

 

Timing on veg is another key to good running and avoiding ring gumming (a real hazard for those who live in suburbia when fuelling is turned up) - the flame front moves more slowly, so advancing the injection a degrees or two is usually a good thing.

I can easily reverse the remap if necessary. So far it's running well on a high concentration of veg, ideal temperature for it like you say. Even on cool mornings a week or so ago it didn't stumble at all, it's still chilly at nights here.

 

I've poked out the fuel tank pickup restriction on SDI/TDI cars before, I actually did it on the Bora this morning but succeeded in breaking the fuel tank level sender somehow.

 

With the software you can also alter the injection timing, I might have a play with that.

My old 98' passat had been remapped and went ridiculously well for a big car, as I mentioned in your other thread it wasn't the most pristine* example in the world.

I have one of these maps on my daily Golf, although it is a PD150 version, and for the map and a knock off Galletto cable from ebay I spent £50, the map was £40 but I think they are now £45.

 

The instructions are straight forward, you essentially make a copy of your ecu and place it onto the desktop of your laptop, you then upload the blacksmoke file onto the newly blank ecu and hey presto a remapped car.

 

Would buy again 

[Lacquer Peel]

Or you can DIY for the price of the cable.

Very true, and after reading that excellent thread above something I would feel relatively* confident to attempt

 

I did mine at least 2 years ago now so the benefits have paid for themselves and to be fair I would have bricked the ECU if I had tried to write my own map at that time
