Re: For those who are thinking about Bluespark...

I note some guys on this thread are quoting fuel economy figures off the instrument panel. A tuning box works by tricking the ECU into thinking it hasn't supplied enough fuel. This means the fuel consumption figure the ECU provides is going to be wrong. This allows tuning box suppliers to claim improvements in fuel consumption where there are none. The only way to do it properly is with bowser and odometer readings. The risk is disappointment.

Re: For those who are thinking about Bluespark...

That applies to any real MPG test... chip box or not.

Too true!

I was going to add that the tuning box marketers want us to believe that squirting more fuel in saves fuel. So how does that work? They claim that the higher torque allows the gearbox to stay in lower gears longer. We know that happens but give me a break! That's like saying the 6.4L Hemi is more fuel efficient than the 3.6L Pentastar. More torque, more power equals more fuel. Fuel saving requires combustion efficiency improvements. Turbo boost increases combustion efficiency and that is something they could have bragged about that would make some sense. Of course this would happen only if the chipped car was run at the same torque/power as the un-chipped car but that ain't gonna happen.

Re: For those who are thinking about Bluespark...

Are there any forum members with real world numbers that were hand calculated using miles traveled / gallons used?

I see you're on Fuelly. Can't those numbers be considered to be equivalent to "hand calculated using miles traveled / gallons used?" Maybe better even, with less room for error?

The Fuelly numbers interesting by the way. Anybody have any comments on them? And isn't there another app that does more or less the same thing, or is Fuelly it?

Oh but you're asking about numbers using Bluespark, aren't you. Never mind. (This post probably belongs in the real world mileage thread, sorry.)

Re: For those who are thinking about Bluespark...

Anyone have some long term use feedback? How's the unit holding up?

Re: For those who are thinking about Bluespark...

While not an apples to apples comparison, I've had a bluespark on my 2011 BMW 335d for approx. 50K miles. Just rolled over 103K miles. I left the box on the default setting and MAYBE, MAYBE see 1-1.5 MPG improvement in both cycles. However, there is a definite improvement in power and torque. Never thrown a code or ran anything but perfect since installation.

As a data point, 75 mi/round trip daily commute, 60-70% highway.

Sounds good. However, I hope you are not using the fuel consumption readout on the dash for your comparison. You can no longer use it for absolute readings nor to compare pre and post Bluespark consumption. The tuning box tricks the CPU into using more fuel in than it thinks it has so the consumption will read less than it really is. This is why the tuning box manufacturers claim these bogus fuel economies. It may be best to go on distance covered per tank. If you can prove me wrong I will be most pleased to hear it because I've just put a Bluespark in myself.

Re: For those who are thinking about Bluespark...

I primarily use GasCubby App as the mileage tracker. It does the old school tracking of miles driven / gallons used. Interesting enough, the dash readout is usually very close to the gas cubby calculations. Normally w/in 0.5 mpg. That could simply be the error rate by how much diesel I squeeze in the tank. I'll be interested to see how much difference you note between the dash readout after installation and the hand calculations.

The GasCubby App sounds interesting. No wait, I don't have a smart phone... only a dumb phone. It's interesting that the difference is so small.

Re: For those who are thinking about Bluespark...

Is it actually known where the fuel usage calculation is derived? I have a feeling that the measuring device is going to be "upstream" of the modified injector flow... in which case the usage will remain correct as indicated.

Solid information regarding the manner fuel user is metered would be good to hear.

Cheers,
Steve
