Performance Boost!?

Fri Sep 06, 2013 4:38 pm

OK... I'm surprised that nobody has brought this up yet... But seems that this little tiger of a ride has a lot of potential for a software upgrade to tease out some more of that torque a little faster. I mean, 402 lb ft. of torque seems to be nicely spaced over the range of speed from the factory. Doesn't it seem possible to tune that for super-fast acceleration fun?

Now, I'm not advocating this - it is a Spark after all, and not at all designed for drag racing or high-speed anything for that matter. But wouldn't it be a fun idea to have a little "quick go!" boost mode every now and then?

The fact that souping-up a new technology and modifying electron control for dragster launches is Bad idea (this is a given), but that point aside, Does anyone on the forum have knowledge (or a good guess) on what might be possible to "tune" this little buggy for more quick take-off fun? Is it just software?

Now before any of you tree-huggers out there vote me off the forum - keep in mind, this is a very natural line of questioning; an expected evolution that is consistent with our great nation's love for automobiles. It happened with hot rods, tuner cars, and motorcycles ... It's a natural question to ponder. And, anyone who's driven a Tesla knows the potential fun I'm talking about here. And those motors don't generate 400 lb ft of torque either!! :shock:

Actually, they do produce about 440 foot pounds and propel a 4600 pound car from zero to sixty in about 4 seconds. The 3000-ish pound Spark EV doesn't come close.

I'm not sure if I'm a "tree hugger" or not according to you, so I won't venture any thoughts on the rest of your post.
Contrary to many folks here, I do NOT own a LEAF.

I don't think more low rpm torque will help at all. This car is tire limited, not torque limited.

Everytime I stomp on the gas the tires squeal like crazy until the anti-skid system engages and cuts back the motor output.

Has anyone put a decent set of tires on this go-kart? This would probably reduce the range, but should definitely increase performance quite a bit.

P.S. The other annoying thing is that the car does not want to go straight when you stomp on the gas. I assume this is due to the FWD unequal length half-shafts or something, but its very disappointing.

P.P.S. Love the car, but a racer it is not. Here is what my SparkEV is replacing:

Since the electric Spark is so new, I expect someone to hack into the controller later after the Spark is older. I would not try to hack and do changes until the factory warranty expires. But we can try to read controller codes and tables, which isn't hacking, yet.

pushing traction control off and then holding until stabilitrack turns off make the spark a little more exciting.

Finished Stage I and working on a Stage II performance boost

If GM would release the Service Manual it would make things much easier

That's because although the spark has 400ft lbs, the software dials it down. It's quite obvious when driving.

I'd love to have performance software for the spark ev. Not only would it fix the annoying power reduction the stock software does when trying to do hard acceleration runs, but it could also help with the torque steer issue which is being caused from the software using stability control to shift which wheel is recieving more power.

Oh and think of the burnouts we'd get if we didn't have the software pulling power there too :)
