Import Tuner Magazine : Project Sipper ('92 Civic VX)

Thanks xntrx!! That's very cool stuff. Consider me signed up for that!!

Yea the failsafe on the fords is if the ecu sees above 4.5 volts from the signal side of say the tps or map, the ecu will cut the injectors just enough to shut the engine down but still show noid. This I very useful info in diagnosing ford no starts of that vintage. It will have noid, spark, good fuel pressure but won't start unless you introduce Gas down the intake. Then it's either fuel volume/quality or a sensor. In which case I start unplugging sensors one at a time and see if it starts. Or you could manually ground a couple injectors while a buddy cranks it.

Don't mean to ramble, hopefully someone might find it useful

Thanks guys. This is at the end of the list due to potential of drivablility issues on a dd. Its a long list also, but I will post progress.

Minus friction, heat, etc.

Exactly. The concept is from motorcycles, where engine braking during shifts is not desired. Historically this has been done through slipper and sintered clutches. Now, the ECU's are being programed to stay slightly open to reduce engine braking. Hopefully the software and controls will bleed over, and we can extend it to full WOT.

This should improve narrow window of speed P&G in tighter traffic, and remain legal (since EOC is not in some areas).

Then automate EOC. Hybrids are legal. :P

Part 5 with results

So what is the message we are suppose to take from this journey?

They created a car that no normal person can obtain reasonably. They spend thousands of dollars on parts, hours on intensive labor, and stripped the car down to something no one wants to live with on a daily basis. All for a result that many many people here achieve year round with nearly stock cars, with cheap DIY parts like garden edging.

I would completely understand it if they chose to implement driving techniques. At that point it would be a battle for max MPG, no matter what the cost. Instead they made it sound crazy to drive under the speed limit, but it's fine to custom build carbon doors and body panels to save a few pounds. So what the average person takes away from this story is that it's cool to spend a lot of time and $$$ on a custom car for good MPG, but it's not cool to simply improve your driving and achieve the same results.

For less than the cost of the doors on their car my VX avg 58 mpg with only one mod. The nut behind the wheel.

I agree with what your saying, but I do love the idea of them bringing awareness of fuel efficiency to the younger crowd. Now I would like to challenge them, and have them show what you can do by implementing fuel efficient driving techniques to this vehicle? This would be awesome, to bring some attention of saving fuel to a their already younger captured audience.

Fuel efficient mods opens the door to their advertising supporters. This could be the next big business for the import suppliers if the would just create a already needed demand for fuel efficient products aero mods, LR tires etc (not snake oil crap)

[ausias]

they need to increase the horses to get good fuel economy with taller gearing and the other very smart and cost effective mods:





and also instead of painting the car they need to wrap the car in carbon because this will increase the apparent performance.

Too late!

We met our goal and look forward to transforming our fuel sipper into a pure street machine.

Ahhh Crap!!!

Oh well you can lead a horse to water but you can't make him do you dishes.lol
