Chip,
What are you on about? In my post I make no argument that its cheaper to do it the prom emulation route in fact, I know it isn't cheaper to do it the Stu way. I'm just interested in pulling electronics apart, specifically firmware and data store - after all, brute forcing the prom isn't exactly rocket science, once you have a foundation in electronics?
As stated, RP Labs is a fantastic technical achievement.
Cheers.

You Think?
I will loan you a twin channel emulator then and you can alter the boost map in here for me yeah?
Can we have the other half please (preferably with address offsets).
In answer to his question though, the tools of the job are cheap nowadays. Its the clunky mapping process you have to get around (which the RP labs modification will do). And as Stu effectively points out, knowing the memory addresses for the various maps is a time consuming thing to work out.
Do you REALLY believe that makes this product bad value or are you arguing just for the sake of it?
Cost out your time for doing all that!
Surely you cant believe the two (a cheap emulator and the RP labs solution) are REALLY equivalent products?
And you STILL wont have the nice monitor software and coil pack drivers and lambda etc!

Cheers.
You still need to then identify which address represent your timing figure at idle when you are 500 rpm above the idle set point, and your temperature calibration for igniton advance based on coolant temp etc, its a HUGE job to do, it would take joe public years to research and learn how to do all that lot!
