On the subject of ECU\'s.
RE-Amemiya have ceased production of the REdom range of "chipped" ECU\'s to suit all 8-bit systems
NA MX-5
FC RX-7
HC Luce
JC Cosmo
However, DO-Engineering have taken up the challenge. Have just scored their 1st "Chipped" ECU for a Cosmo guy here in Sydney.
Watch his progress at
www.eunos.com.auWe will be doing a before/after dyno session in around 2-weeks time & will post the results
Their ECU upgrade should do the same as the REdom version.
Remove 180km/h speed cut
Remove 0.70-bar boost cut
Remove conservative IGN map
Remove conservative Fuel map
Remove "limp mode" on trivial error codes
More aggresive Fuel/IGN map
More boost, up to 1-bar
Use up to 100% duty cycle on injectors
Here is a pic of my "chipped" ECU from RE-Amemiya
Note "REdom" stickered Eprom chip (standard 2756D) in foreground. This is the reprogrammed IGN map.
Note mezzanine board just aft with processor, RAM? & eprom chip combined. This is the reprogrammed Fuel map & fuel controls such as boost cut, speed cut, limp mode.

The DO-engineering version looks 99% identical.
