The DIS (Ignition) Module is no small project. I have been working on a replacement for well over a year now and still actively pursuing the project.
The electronics are imbedded in epoxy, making access & repair of electronic components impractical.
Add to that, the program stored in the ROM chip cannot be read & code is unknown.
The "replacement" will be plug & play into the engine harness, although the electrionic connections may be wire leads from the module to the connector instead of the present one-piece mold for all 4 connectors. It will require utilization of the aluminum mounting plate from the original DIS module.
As for the development cost, I expect it to exceed $35,000.00 to produce beta test samples. Development will include actual engine dyno sessions before releasing the beta modules.
I hadn't planned on releasing this info because ultimate unit costs, delivery schedule, etc. are not known and always have hiccups along the way, but I couldn't ignore the concern for the future of our ZR-1's.
