A fair bit done for once- but not without its issues

So finally made it to fuel light on in this for the first time..

672.1 miles, on 45.66L of fuel! that is 66.9MPG (imperial) or 55.7MPG US

1081.6km travelled before refuelling- nice to get a kilo tank on the first run. Also made #6 in the top 10 Diesel cars in the garage.

I refilled it with 15L of WVO (at 50p/Litre ($0.78/L)
and 30.66L of Derv (at 116.7p/L $1.82/L)
Total refuel cost was 43.28($67.40)
giving a cost per mile of 6.4p($0.10/mile)

Total Runtime to use the tank up


Average Speed


Matching Miles


Range Remaining


The trip computer seems to be 7.7% out


15L of WVO later


Fully Derved up

Another tank into this beastie 585.2 miles covered- 58.79mpg.

the drop from 66odds was likely down to all the drag racing and a bit more town work.

the refil consisted of 30L of veg, and 15L of derv. total cost was a most pleasing 32.49.

gives a cost per mile of 5.6p

Just been up drag racing in this again yesterday- after doing a retune to it.

bhp up from 90 a fair bit, torque up from 166ftlb to 225ftlb. It looks to be on course for another circa 60mpg tank- even with the drag racing and remap..

end result is running 16.8s on track rather than 18s

the mapping was done via the obd2 port and was simple enough to manage when I'd learned the basics.

you can alter the values in a variety of ways..


Freeware software is available online that allows you to alter the values that map the following criteria:

Driver's Wish (this controls the max fueling at given throttle pedal input %)


Boost Target (Maps the requested boost level from the turbo for a given RPM/Fuel volume)


Smoke Limiter (Controls volume of fuel based on air volume and RPM)


Torque Limiter (Sets fuel volume limits based on RPM)


In essence then, I have the ability to raise /lower fueling levels and boost levels on a fairly granular basis.

The output is available via the "View performance" function:

The software is free online now? That's a great tool! The torque improvement is wonderful and it appears to be spooling up very early too. No worn out vacuum lines, stuck VNT veins or oxidized grounds in the engine bay it seems. Does that engine have the intake manifold shutters/flaps? My 2004 Jetta did. It always worried me that they might let go and get ingested into the engine. I see the antifreeze reservoir has the sensor where its above the fluid line so no worries about antifreeze in the wiring harness. Couple of the other things to check is the seal that keeps moisture from freezing the emergency brake in winter and the adjustable yoke that keeps the back brakes equally engaged or slacked. In a few months the glow plugs may need attention for cold starting. I would inspect the fans, fan control module and alternator nut as well. I could be mixing up problems from different years and models but I've seen many these issues in our cars here. Oh and lift pumps and transaxle boots are two other things I just thought of to inspect. You've probably thought of these things. Hope something here is helpful to you.

Had a go at remapping this last week, via the OBD2 port.

Software is available that lets you alter the various maps making up the ECU programming.
The numbers in the boxes at the top show the maximum fuelling permissible at the given rpm/other criteria.

Suffice to say, It went from 18.009 for the 1/4 mile to 16.832- a decent improvement.

Throttle Pedal Mapping- Tuned


Throttle Pedal mapping- Stock



Boost Limiter - Stock


Boost Limiter- Tuned

A trip upto Crail to test out the remapped Octavia- with a good measure of Retro Drag racing and show cars thrown in!

Enjoy!

Yeah I had a quick glance over all the n75 valves and boost/vaccuum pipes before mapping. all seemed in order.

I'll need to get it on the rolling road to see what it makes.

next up is maybe to have a fiddle and see what an economy map looks like..

thanks for the hints and tips re what to look for-will peruse in due course!

Time for another fuelling today-

602.3 miles on 47L (using a 44L WVO, 3L Derv mix). This tank included 17x 14 mile runs at Crail, after I'd remapped it.

Very pleased with that 58.3mpg (48.55mpg US), and a total fuel cost of 22.33 ($34.61)- giving me a cost of 3.7pmile ($0.057mile)





On the run home I took it very easy- and had this as the shown average (based on the computer being 10% optimistic, I reckon a genuine 80mpg (66.61mpg US) over 17 miles.)
