DSM's come with EPROM ECU's..what about the 3/s? - 3000GT/Stealth International Message Center

NOMIEZVR-4 · 09-27-2006, 09:50 PM

I know its a noob question, but as some of you may already know, us DSM'ers can do a ton of stuff with our ECU's because of their eprom capabilities(whoever is lucky enough to get one). Im not going to go much into details but I was wondering since the 3/s car are infact made my Mitsubishi as well, why isn't there any intrest in ecu modding for the 3/s platform? Has it been confirmed that 3/s cars dont come with eproms?

Thanks

The 3S does have an eprom, it's encrypted much differently than the DSM one is though. I believe the only ECU hacks are a raised rev limiter at the moment.
Unless I'm completely mistaken here and misunderstood something lol.

and to the effect the raised rev limit isnt even a hack its just overclocking it.

The 3S does not have a programmable eprom. That's why you don't see ecu hacks for our cars. The 98/99 models are supposed to be programmable afaik, but no one has really put much effort into decoding them due to the very limited user base for those cars.

FYI, in the DSM camp, 95 year cars had the most probable chance of having the EPROM for the 2nd gens and in the 1g era I believe it was the 90-92's.

Its dissapointing...

The benefit with eproms is that, if someone were to run 780cc injectors all they would need would be a chipped ecu for the fuel control..

No, only DSM's are eeprom based.

97.5+'s ARE reflashable, there just is no market to really make a product for them.
