ECM And Ignition Module Availability/ replacement
Alright.
I know there is the chance of having the ECM Repaired, if not there is a MegaSquirt variation, although every time I inquire for a price I hear crickets.. So is there going to be a megasquirt variation, with it what do you lose? What about the Ignition module, What happens when they break? Where is the option for replacement? Has the the registry thought about sponsoring or helping sponsor for the creation or recreation of this part. That is truly one of the major components that if we cannot get a replacement our motors become boat anchors.. thoughts?

While the IM might be Adequate.. what happens when/if these start to fail? That is more the concern of mine Russ, I know you mentioned price, i email ed them too.. I honestly doubt it is on their website yet and I emailed months ago for info

Re: ECM And Ignition Module Availability/ replacement
The quest for both of these modules is a worthy endeavor, for sure! In fact, it has been kicking around for quite a while - and monitoring MS has been keenly observed.
The DIS module is critically important; made more so by limited availability of spares, and (frankly) Graham is and we're all aware of that. I believe a Registry endeavor to resolve the availability of these critical parts is well within the purview of "Keeping The Legend Alive". At present, the club hasn't got an R&D entity or committee to address critical components. Maybe it is high time the Club should consider one? After all, these critical items aren't getting any more available with the passing years, right? We're a NON-PROFIT organization. At the moment, the Registry budget (available to inspect by all club members on the Members Only site) is essentially balanced between dues and outlay for everything the Registry does (e.g., organizing local and regional gatherings, the FORUM licensing and maintenance, membership perks, etc.). We have to operate within the non-profit rules for tax exemption purposes. NOT that we "can't" embark on a quest to resolve/develop (these) parts, and I believe maybe the Club should. But, we have to secure resources (people and $$$) to head up the development w/o nullifying our tax-exempt status; e.g., agreeing as a club to increase dues to fund efforts to procure say an outside source for the DIS module. Having been involved in R&D (in a previous life), I have some ideas on some of the key points of such an endeavor, and I think the Club would benefit greatly by tapping into the enormous talent held by certain members of the organization, as well as others (e.g., Jerry) who may have already embarked on "the quest". Discussion, pro-con, is welcome and healthy and certainly germane to the preservation of our cars . But, before volunteering "somebody or the BOD", understand it is going to require the commitment of tremendous time and effort and talent to guide the process through. And, to keep us out of legal trouble (taxes for one thing) certain steps will have to be considered and taken before any $$ collected or is diverted to the effort. Note: Anything I've said here is w/o intent of malice, and I don't believe I have over-stepped any rules of decorum, far as being a member of the BOD goes, as it pertains to simply opening a discussing at this point. But, any Registry sanctioned/funded efforts (business) of this sort will have to be done with direct BOD involvement to assure we remain w/in legal (tax exempt) and by-laws guide lines. Independent persons/group efforts NOT entangling the Club in any way are not withstanding, of course.

Re: ECM And Ignition Module Availability/ replacement
I thought I had an email that mentioned the MS3-Pro (Megasquirt) price, but I can't find it. It was around $2,000.
I have it in my car and like it. The only missing functionality I've noticed is the MPG dash display. I'm a bit ignorant about the ignition module. I'm assuming the MS3-Pro in my car is working in conjunction with the stock ignition parts. Having the Registry work with DIY Tune for better prices is a great idea. I know the guys started the LT5 ECU because they think there's a potential market. They are also working with Graham at Lingenfelter, which is encouraging, and might help tackle the dash integration eventually. |

Re: ECM And Ignition Module Availability/ replacement
I don't believe the MS solution includes replacing the IM. In speaking to Graham, he thought the current ignition was more than adequate, although I have always thought it to be an extremely critical and irreplaceable piece. I'd like to see an alternative developed that takes advantage of the current CnP technology.

Re: ECM And Ignition Module Availability/ replacement
I have been dealing with older FI cars for some time now. What I have noticed is usually Cold Solder joints fail or capacitors/transistors die. Anyone who had an older TV back before they were really cheap may remember the TV repair man. They were good at working on small electronics and replacing these critical electrical components.
What we need to find an old DIS and send it off to an ECM rebuilder to see if it can be re-furbed. Such as redoing all the solder joints and replacing any questionable components. I had old TV repair shops do this for me in the past with great success. Can anyone tell me exactly what the DIS does? Does the ECM not send any type of signal to the coils?

Re: ECM And Ignition Module Availability/ replacement
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.
