Re: ECM And Ignition Module Availability/ replacement
 

While I appreciate all the kind words, please know that Graham Behan is the guy who really deserves all the credit.

Re: ECM And Ignition Module Availability/ replacement
 

Though I'm sure he wouldn't remember me, I had the pleasure of meeting Graham at the 2009 C4 Gathering in BG. That's the year I believe he brought the LT-5 prototypes with him.... like 4 or 5 different ones with different intakes and such... really cool stuff.

At any rate, thanks to Graham as well!! You guys are the types who will keep the ZR-1 alive for a very long time to come.

:cheers:

Re: ECM And Ignition Module Availability/ replacement
 

Jerry,

My Thanks to both you and Graham Behan for taking this project on and continuing to move it forward. :handshak:

Re: ECM And Ignition Module Availability/ replacement
 

All, we are now at a stage where we are completing the final stages of software development error checking and reporting communications between the ECU and the new DIS module, as to ignition status etc. The module hardware has already been tested with simulated crank sensor inputs and the next step is to fire coils with an actual crank sensor input, will provide pictures and hopefully video when this event occurs. After that we will be testing on actual engine/vehicle.

Regards

Graham

Re: ECM And Ignition Module Availability/ replacement
 

Great News Graham!!

I am curious as to what the price point of these units will be

Re: ECM And Ignition Module Availability/ replacement
 

That's not my call, Jerry?????

Re: ECM And Ignition Module Availability/ replacement
 

I was told by someone at DIYautotune that they cracked a dash on a ford and may take another stab at the unresolved dash issues on the zr1 megaquirt. Know anything about that?

Re: ECM And Ignition Module Availability/ replacement
 

Yeah, it was directed towards Jerry, my guess is it is a bit early for the pricing

Torqhead has it working for the LT1 cars with their ECM. Wish TorqHead would do an LT5 ECM

Re: ECM And Ignition Module Availability/ replacement
 

I have heard that they have been reaching out to people that may be able to supply a dash and ccm for them to attempt to monitor coms and discover what the check sum and serial data packet responses are, not sure of progress.

Re: ECM And Ignition Module Availability/ replacement
 

Jeff,
I simply do not know what a semi-guess price range is, let alone the final price point. Please rest assured, I will do the best I can when all the numbers are in. Right now, we are trying to wrap up the R part of R&D. Will then build a test unit, verify that, then build a few more beta test units for in-car testing. IF we get through those steps without major issues, we can finally look towards manufacturing. Manufacturing is quantity sensitive for costing, so that's a critical decision I will have to work through.

I know this is a long-winded answer to what appears to be a simple question, but it's all I've got now.... and a dedicated effort to resolve the availability issue at a feasible price point to keep the LT5 viable.

Re: ECM And Ignition Module Availability/ replacement
 

Thanks for posting Graham! !

Re: ECM And Ignition Module Availability/ replacement
 

I've spoken to both MS and Torqhead. I have given Matt at MS the contact info for Torqhead. He said they were going to reach out to them. I'll see MS again at PRI this winter and press again. MS has the engine end down pretty well and Torqhead has the CCM data stream figured out. Really wish they would get together and sell their info to the one that wants to take an LT-5 ECM into the market!

Jerry,

Thanks, I knew I was asking early.. I am sure you will do your best to meet the needs of owners

Re: ECM And Ignition Module Availability/ replacement
 

I have one of the megasquirt LT5 ECUs. I would love to be able to update it for full functionality.

Re: ECM And Ignition Module Availability/ replacement
 

I like that TorqHead uses an OEM PCM, that gives us OBD2 functions/data

Re: ECM And Ignition Module Availability/ replacement
 

Ignition module testing has now verified input and output signals to stock ecu with stock harness, picture attached.

Next to verify full range of ignition advance and retard per the limits in the 1995 calibration, using this because it is the maximum stock values.

Re: ECM And Ignition Module Availability/ replacement
 

Graham, is that big header connector readily available from somewhere? I am in need of one for a project

Re: ECM And Ignition Module Availability/ replacement

Re: ECM And Ignition Module Availability/ replacement
 

With all this discussion of the DIS module, if it were me, I still had Barney and its DIS still worked, I'd get the plenum off, remove the DIS module, clean any dirt/debris of it, spray the connector with contact cleaner, clean the mounting surfaces on the module and the plenum, then apply fresh dielectric grease per the service manual.

The grease is important because its how the module sheds heat to the plenum.

Hopefully the replacement DIS module project undertaken by Jerry and Graham is successful.

Re: ECM And Ignition Module Availability/ replacement
 

Hib,

Are u suggesting dielectric grease for mounting of ICM?
Its white heat sink grease. Just wanted to make sure that was clear.

Salvaged from an OE DIS Module for R&D

Re: ECM And Ignition Module Availability/ replacement
 

So is the final version going to have a plug or pigtails?

Re: ECM And Ignition Module Availability/ replacement
 

Our objective, if we can meet it, is to not mount the long connector on the board, but to bring out a pigtail with that connector on the end of the pigtail to facilitate an easier connection. That's down the road, we'll see when we get there.

Re: ECM And Ignition Module Availability/ replacement
 

the male connector or the actual dis circuit board connector?

Re: ECM And Ignition Module Availability/ replacement
 

Actual circuit board connector

Re: ECM And Ignition Module Availability/ replacement
 

UPDATE! DIS MODULE SPARK TEST !UPDATE

A significant milestone has been achieved. Graham Behan will be along shortly to add more technical in formation, but in the mean time.......

Spark Load Test to 8,000 rpm. Circuitry passed with flying spark from terminal to terminal without any problem.

Graham has it up on Facebook. I revised the link above to show the video there.

Have you tried posting it to YouTube? I saw it on Graham’s Facebook post but the quality was poor. Good work can’t waut to see the final product.

What are the next steps?

Re: ECM And Ignition Module Availability/ replacement
 

Congratz on a significant milestone! Packaging/cooling, duration, and temperature cycling tests to follow, I presume. But, this is one of the most significant breakthroughs for our cars in some time! This ONE item may have a truly significant impact on market value of our cars too! "Keep the Legend Alive!":dancing

Re: ECM And Ignition Module Availability/ replacement
 

There are many steps to complete in the process of validating the hardware and software going forward. The video shows what actually is a pretty significant stress test for the circuits simulating a grounded plug wire. Next up will be connecting all coils and wires and debugging the code for the auto dwell function, followed by a more comprehensive test cycle with the simulator. Then connecting to a factory harness and ecu to test the est functionality. There will, no doubt, be issues found in the debugging process, but progress is being made in pretty significant steps right now.

Re: ECM And Ignition Module Availability/ replacement
 

This is the prototype DIS Module circuit board & billet case, that is controlling the spark firing the ignition coils in the still photo and video shown in post #106 above. It interesting to see the spark at a single coil, during the demo from idle to 8,000 rpm.

Re: ECM And Ignition Module Availability/ replacement
 

Graham, I was wondering if you happen to know a part number for the mating connectors (male) for the two connectors (one 4 wire and one 2 wire) that plug into the coil pack? I would like to make a pig tail that plugs into the stock harness. Any help would be appreciated. thanks.

Jerry,

Will the final units be potted or conformal coated? Since it will live under the hood
