Just wondering if our cars ECMs were meant to be tunable, because I'll bet if GM wanted to, they could make it impossible. But then again, they might want to make it very possible intentionally so that there are more 3rd gens that are tuned and fast, thus more popular!?

Are there any cars made that are intended for you to be able to tune from the factory? I imagine there being a lot of liability problems when people mess up their cars if that were sold.

Just some boredom thoughts..

 

Our factory alignments are made for the slow dumb people who cant drive.

U can easily be more aggressive with it and suffer no ill consequences.

Do u need 150mph? the TPI 350 cars could do it and TTA's easily pass that mark....................

Cars are built for the general public, meaning safe, always easy to control, someone with a brain and a little ability can easily push the envelope further than the general public who are dense and of a "herd" mentality.

If u werent above average intelligence of the general population, you wouldnt be here asking things about tuning lol U would be satisifed with good enough and how it already is, not what u could do with it if u opened up your mind.

No car company wants warranty issues, hence everything is safe and conservative. Not to be mean, but the general population does tend to be stupid and/or uneducated, which also causes problems such as: "U gave me the car that made me hit the tree at 150mph!" lol

Did GM intend us to tune the ECMs? I highly doubt it.

If you think that GM was working 3-5 years ahead on the ECMs before installing them, then all the technology is based on early-mid 1980s microprocessor knowledge - which was still in it's infancy at that time. Memory space & execution speeds were the main concern at that time, not security. I know this, because I was working with micros at that time myself and there was limited knowledge.

Security against reverse engineering of the code wasn't a concern because most of the general public were just starting to learn about computers, such as the Apple II and Commodore 64. The Internet wasn't even a dream. So the vast majority of the population just didn't possess the knowledge to hack the ECM. Just a few odd *****.

But in the last 20-25 years, the number of the odd ***** has grown as well as the knowledge. Where a number of guys on this board even have fully functioning code. GM never even saw this coming.

 

Im curious, does anyone seen/read about the tools GM used to tune our ECMs, like the interface. Woulde be interesting to read about the development process..

Thanks

 

Those are good points, at the time it must have never crossed anyones mind that ECM or PROM tuning after the factory would even take place.

The reason I ask is actually based on a conversation with a guy at work who thought there was no way Id be able to change anything about my car's computer haha.

It is correct that as for as cars' computers go, anyone on here IS more intelligent than average, simply by... reading! hmm, reading is easy
