Call for Beta Testers - EDIS hard rev limit module
Posted: Mon Aug 20, 2007 3:37 pm
Yes, finally!
We have a design in hand for a hard rev limit module, designed to be triggered by the REV_LIMIT output of the MJLJ. I'm working on a full project page in the wiki, but in short, the basic approach solves these simple requirements:
1. Disable coil packs from firing upon command from MJLJ module
2. Prevent an early ignition event when rev limit is activated 'asynchronously' during coil dwell period.
The circuit is simple and rugged, using a power mosfet to 'current starve' the coil when rev-limit is activated. It does not abruptly cut power to the coil.
After I complete my testing here, I would like to send out some modules for further testing in the field.
If you're interested and able to help out, send me a private message indicating:
Engine type (specifically number of cylinders)
MJLJ Version you are running and how long
If you have an EDIS test bench setup (bonus points)
Of course, in exchange for your testing feedback you are welcome to keep the rev-limit module at no charge.
Thank you!
