There where products in the old days up to 1996 that you could emulate the eprom using a laptop. Tuning was very simple as on the laptop it would highlight the map the car was in and on the dyno you could make changes instantly going across the different load cells. The eprom would be saved on the laptop and a connector would be plugged into the ecu or soldered on in many cases.
It would also make identifying maps much easier. This worked well up to the 29F800 range of eproms and then the ECU's just got faster in a big hurry and rendered the technology from EVC obsolete.
There was a period after this that was the dark ages because you would need to solder the eprom on and off each time a change needed to be made and around 2000 things went to the flash via OBD route.
^^ This. It's the reason a TunerPro RT (Real time) exists. It actually shows you the cells currently active too. It's awesome.
Aaaand not going to happen for us most likely. But we can dream. "
Unless you know Philly me telling you the area seems useless... The highway in question will be effectively closed down with nearly a 2 mile uninterrupted stretch of road. Beyond that its not very prudent to advertise the area!
You want to race on public roads? I don't do that and I'm not risking getting my car impounded or jail time because some people on the internet are butthurt.
Either arrange a strip rental or forget the whole idea. "
" No, dyno, can't see the point of a dyno, if the software for European cars don't allow me to adjust fueling timing or VE tables. I have to live with the tune they write for me. I do think the max boost pressure gives some clue, the power band smoothness is differently noticable. "
