Madness Autoflash
1 - 20 of 60 Posts
Here's my take on this flash with no first hand experience. I've contacted about a half dozen companies that offer a tune for these cars. My take away is that all of these companies are using the same tune file and reselling it. I say that because none could tailor the tune to my specific car. This is pretty common practice. I've remote tuned two other cars with other companies. If they were making these tunes themselves it would be easy to modify based on a customers needs/wants. Also I called Smart Madness specifically about their tune. They didn't offer the autoflash option at all to me but said I had to send in my ECU. I also wasn't impressed with the level of knowledge I received and they had no dyno charts to back up power claims. Granted I am little more hardcore into the auto world than most so I tend to ask out of the norm questions.
With all that said there are probably some gains from a tune. Exactly how much who knows. I plan on dyno testing one beginning of the year. If you want a tune I'd just go for some of the cheaper options out there. OE Tuning offers a tune for $300 and is probably the same exact changes.

You're talking about two different products here. The MADNESS Autoflash is not an ECU tune and does nothing to horsepower or the motor itself. The Autoflash is a TCU remap. It will completely change the way your transmission behaves while speeding up shift times and bypassing torque limiters.
Now because it does not change anything in the actual motor it will not affect smog and emissions.
If you are after an ECU tune we have that as well;

The top speed of a vehicle is limited more by the motor than the transmission.
The Autoflash does not change the gearing ratios or top speed. It is software that makes the transmission snappier and cuts the long shift times.
Let me display my ignorance.
The OE tuning folks offer an OBDII unit that can flash a certain number of vehicles for $240.00. Are they just selling the unit and the software is more? If the OE tune is typically 295, why sell the unit to a customer for less, unless they want to use it for marketing, but in that case, it's not a very sound marketing strategy. This one has me baffled, especially since it can be re-used on multiple vehicles and it set to use Android software.

The tune 'marries' to a single vin.
The flash unit is useful for instance where you don't have to remove or send out an ecu, downing the car until the ecu comes back.
Also, you can reflash the same vin should you bring in a car for a dealer service and they wipe the tune...
This explains everything. Thanks very much!

I'm late to the party, but here's my take. There are four things I would do before even thinking about adjusting the software.
- Install a performance intake. The stock one is crap.
- Install a performance exhaust. The stock one is crap.
- Install better ignition coils.
- Pay a little extra for some top of the line spark plugs.

Have you done these things? If so I would like recommendations and experienced results. right now I am stock but for a KnN filter a Side Scoop and the Go Pedal.
I have top of the line spark plugs and the original coils. Which coils would be an improvement over the OEM parts?
Also: what intake and what exhaust manifolds? Why are these crap?

Why are the stock intake and and exhaust crap?
Let take a look at the intake. In particular, the path incoming air has to take. First it goes through a corrugated hose with lots of interior bumps. It takes a right angle turn through the filter and then takes another right angle turn to the inlet pipe. The inlet pipe takes another three curves before arriving at the engine.
Also attached to the inlet pipe are two large sound baffles which are designed to reduce sound by misdirecting some of the inlet air.
All those bumps and turns create low pressure eddies which impede the air flow.
If that wasn't bad enough, all the time the air is swirling in those eddies it is sitting above a hot engine. High inlet air temperature equals a less efficient engine.
This post is already long enough, but a similar situation occurs with the stock exhaust.

I see what you are saying... just worry the car will fail the Smog check in California if I have done all these. Am I worry too much?
