“nah, people moved on to $200-400 Hondata S300 or Moates Demon/Ostrich because burning eproms is the most stupid way of tuning cars ever devised” Doesnt really work if you arent using off the shelf parts from one vendor. Slap Spoon Intake and Exhaust, replace prom with one of the “high quality firmwares ready for those cars” and job done. This indeed works if your mechanical modification to the car is 100% repeatable. > Tuner-san … that there was really no real reason to do so as he already has some high quality firmwares ready for those cars Typical Japan, retro futurism personified :o

There are >5 Honda tuning programs able to interpret raw eprom images, with couple free like TurboEDIT, yet here we have a tuner master from Japan unable to dump emproms and not curious enough to figure it out, just collecting physical chips.

I asked a few details about it, like where is it from and what’s different compared to the Spoon one, but since he can only copy the firmware from one chip to another using his machine, he had no mean of actually reading the code and answer my questions >He proudly showed me the newest addition to his collection: my EG6’s unknown firmware. You can trivially convert 92 car with a small adapter board, ECUs shipped with all the needed firmware and hardware in place sitting unused for 7 years.

They also do logging for easier diagnosing of problems, some even have bluetooth option so you can monitor live stats on ODB0/1 cars.Īnother crazy Honda fact: all their ECUs from 1992 (P05) onward had full facility to drive individual coil on plug, but officially Honda switched away from mechanical distributor in 1999 (S2000?). This lets you change values live during the tuning session. Hondata & clones employ Xilinx CPLD and SRAM/MRAM performing Eprom emulation. Nah, people moved on to $200-400 Hondata S300 or Moates Demon/Ostrich because burning eproms is the most stupid way of tuning cars ever devised – you want to see changes live on the dyno after every PgUp, not wait 15 minutes per iteration while tuner erases your chip and burns new one. > which is why people tend to turn to some full-aftermarket solutions instead now. >Those EPROMs are now out of production and thus stupidly expensive Posted in car hacks Tagged ecu hack, Honda engine, reverse engineering Post navigationĪs far as contributor competitions go this second writeup by Chris Lott wins hands down – links to github and previous article highlighting same author. Be sure to checkout our articles about his old Subaru hacks from in 2018 if these kinds of projects interest you. We also recommend that you be like and carry an Arduino, a breadboard, and some hookup wire with you at all times - you never know when they might come in handy.

We look forward to more updates as posts the results of his reverse engineering efforts. He also wants to perform a little tuning himself. He started a GitHub repository for this effort, and eventually hopes to identify what has been tweaked on this mysterious ECU chip compared to factory stock. He’s currently digging into the firmware, using IDA and a custom disassembler he wrote for the Mitsubishi M7700 family of MCUs. Advantest R4945A EPROM Duplicator c.1980s

A few minutes of Googling reveals the ASCII pinout of the 27C256 EPROM, and he whips out an Arduino Mega and wires it up to the chip and is off and running.

After a false start trying to use the serial port on the back of the PROM copier, he brute-forces it. This tweaked ’s curiosity, and he wondered if he could obtain the contents of the Civic’s mysterious PROM. These days he uses it to maintain a backup collection of old ECU chips from cars he has worked on. pulled out an old PROM duplicator stashed away under the counter which he originally used as a kid to copy PROM chips from console games like the Famicom. took his Civic to a shop to have some burned-out transistors replaced in the ECU, and a chance conversation with the proprietor sends him on a journey into the world of old EPROMs.

Making things more interesting each one has a tuned EPROM, the Civic’s being of completely unknown origin. Both the 1996 Integra and the 1993 Civic have similar engines but different ECU hardware. He recently began to delve into the Engine Control Units (ECUs) of the two old Hondas that he uses to get around in Japan.
