Re: Anyone care to guess...
Sorry for the delay in responding. I've been busy with work and haven't even been able to get on the forum recently.
Most of my recent free time has been spent doing other work on the Z that I had been putting off: Header install Fidanza install PowerTorque clutch and pressure plate Bill B short throw shifter(modified with a custom neutral sensor for future remote start system install) 4.10 gears New U-joints Poly suspension bushings That being said, I have completed the wiring harness mods and am currently working on the crank and cam sensor solution. I've now got a connection on the CNC machining for the LS1 reluctor mount. I am swapping out tuning on a heads/cam/headers/intake/TB/MAF C5 for the CNC work. I'm killing two birds with one stone, as this is also getting me experience on tuning the LS1 PCM. I still need to do bench testing to determine if the pencil coil that I've got will work with this system. If so, I'll purchase 7 more and be ready to install the system on the car, load up a base tune, and start playing with the system on primaries only. If that all looks good, then I can start working on the secondary issues. Also I will need to wire up the PIM to see if I can get the LS1 PCM talking to the CCM on the 8192 baud bus. Just a word of warning: As I have stated from the beginning, this will not be a plug and play solution and will likely come in at a higher cost than the MegaSquirt ECM solution that Ron has spearheaded. I have my reasons for going with the GM LS1B PCM. Primary among them is that the MS unit does not have the capability for certain hardware control pertaining to future mods that I have planned. After attending the presentation by the MS guys in BG, I am impressed with what they and Ron are doing. If anyone wants a plug and play alternative to our ECMs, you'd be better served going with their setup. My intention is not to design a system to compete with them. My primary aim is to implement some new technologies on our engines that require the GM PCMs. Jep |

" Primary among them is that the MS unit does not have the capability for certain hardware control pertaining to future mods that I have planned."
do tell, please elaborate!! this is an amazing project and I've been following it closely. just need to get you a different "day job" so you can wrap it up and put a bow on it. outstanding work! although I am thoroughly impressed with the "raptor squirt" (sorry, couldn't resist, new dinosaur porn star), the factory ECM is very capable from a tuning perspective, do you like EFI Live or HP Tuners better and why? I'm looking to purchase and need some perspective on the LS ECM platforms. again, thanks SOOOOO much for doing this and keep us posted on projected ETC and pricing. looking to purchase a better tuning solution for the LT5 to prep for a turbo build down the line. TIA!

Re: Anyone care to guess...
I would really like to have some datalogging capability on my Android Tablet, Which is not created for the OBD1 stuff,
otherwise I am satisfied with my OEM ECM

Re: Anyone care to guess...
Jep,
Any chance you're looking at integrating the reluctor w the balancer? BTW, I have seen where an ABS sensor is used to trigger the CnP.

Re: Anyone care to guess...
I just picked up a 24x reluctor wheel so that I can go CNP, not COP like you are doing. I will be using 8 GM GEN 3 or GEN 4 coils for my conversion.
I will also be using the 0411 PCM tuning it with Tunercats OBD2. Currently I am running a 4x CKP reluctor for CSFI, and 1 x CMP sensor located in the distributer. When I go 0411, I will use this cap on top of my distrubuter, instead of this stock crab style distributer as I will need the distributer for a 1x CP signal and to drive the oil pump, but wont need the 8 high tension wires coming off of it. If I wanted to go with a GEN 4 ECM I can use a 4x reluctor in the distributer body instead of 1x and use a 58x reluctor on the crank. Once you get a 24x or 58x crank CKP sensor signal, the limits are endless.

Re: Anyone care to guess...
Unfortunate we don't have the access to an EFI Connection conversion like other SBC. Been around a while now. Part of the LT-5 issue w this dwell control is incoporated into the ICM not the ECM. So its pretty well hardwired for the current ignition coils. With some other module, even one made to handshake w the current ECM and use existing 9 slot crank reluctor and trigger, we still need a way to control dwell since the CnP have optimal dwell times different from stock coils. Unless someone wrote some code integrated w stock ECM to do that.

Not sure if I understand your issue, once you go 0411 PCM, use it for your dwell control, the tables are there, gut the LT5 ignition entirely. Then set them up for your COP coils. But I must be missing something. Good work on your project. I have blazed some EFI trails, it can be challenging, but rewarding in the end.
