Had this drag racing again at the weekend and ran a PB of 16.677 @82.4mph

this was in part due to some lightening by removing the rear seats/emptying boot/removing spare wheel etc.

Another thing that contributed was swapping to front tyres with some actual rubber in them- meaning it can actually get off the line!


I'll upload some pics when at the PC

I've been playing with the pump voltages on the map. The voltage controls the rate of fuel delivery - I.E. how close the pump gets to the theoretical 51mg of fuel max.

Apparently the highest you can set is 3.99v before you get into limp mode.

I built a version of the map with the pump voltages turned up, loaded it on and went for a run.

The onboard logging showed that it was delivering more fuel, more readily, and the car certainly seems more responsive.

I took it back off as the throttle response was bloody sharp, and would likely be a hindrance in day to day running.

Will keep it for the drag strip, as I think it may help

Had some serious trouble with this - combination of fuel filter issues and pick up/level senders being blocked

Big bump I know, but... How are you getting those MPG figures? I have a virtually identical car (only the '02 estate version) and the most I can get out of it on a run is about 63mpg UK. Maybe a little more if I wasn't commuting in rush hour traffic. Granted it's winter at the moment, so it's cold, windy and dark (ergo headlights), but still. However, I have noticed that my trip computer seems pretty much dead on accurate.

Also, what are you using to do the remapping? More power could be useful for me, I'm eyeing up the towball fitting on mine and wondering about towing something race car shaped.

Bonus muddy glamour shot:

Its now away to the scrapyard in the sky after it refused to bleed any air out the fuel system..

Re the mpg, I ran 40psi in tyres, stuck to 60-65 on motorways (no pulse and glide) and tried to coast or in gear decel to a stop wherever I could.

63 is reasonable on a run - just stick at it

all the details re the remapping can be found earlier in the thread or here:

That sucks! That's a failure mode I've never heard of before.

That's pretty much how I've been driving, although I'm running 35psi (which I think is the recommended pressure). I managed 65mpg on my commute the other day, so I'm improving I guess.

And thanks, I'll give it a look. I wonder how much extra it would cost on my insurance...
