Not sure Lingenfelter bought them all. Jerry's Gaskets has tons of parts. Only had to find parts, CCM, ECM and Ignition Module, but the IM is pretty stout.. As for Power, yeah I only have headers on mine and 4.10 gears.. I did other mods as my last vette (89 L98) had a built Miniram motor. I do know one ZR-1 ( another friend of mine) that coule give you a good run.. it runs 10.5's in the 1/4 (on stock gears I think)..
Alright, CCM Messaging:
I want to thank everyone for the help I have received. I have looked at a couple messages with the CCMs I have. So of this info cam from NomakeWan as well
I am pulling this form the ECM Simulator that NomakeWan posted around page 18. I was woking on the Arduino to test the messages which is why they are formatted the way they are
Edit: Checksums may not be correct at the end, witht he simulator I had it always calculating the Check sum as I kept changing values and compiling, so that was the quicker way to get the correct messages
I am debating on buying a 1994 CCM for testing purposes, but have 4 others so not quite sure I need it. I need to finish my test bench which will add functions to the ECM Simulator for some of the cluster displays..Code:94-95 ECM->CCM message.. LT1 only 0x41, 0x67, 0x02, 0xF5, 0x00, 0xCD, 0x87, 0x01, 0x00, 0x00, 0x00, 0x00, 0x88, 0x00, 0x48, 0xFF, 0xFF, 0x00, 0xFF, 0xFF, 0x40 1992-1993 ECM->CCM LT1 Message 0x41, 0x64, 0x01, 0xF3, 0x00, 0xCD, 0x60, 0x01, 0x00, 0x6F, 0x0F, 0xD6, 0x83, 0x00, 0x51, 0xFF, 0xFF, 0x13 I found this message was happy with CCMs set for LT5 or LT1. I tried to twiddle Byte 10 MSB, but no changes as I could see 1990-1991 ECM->CCM Messages L98 Message = 0x41, 0x61, 0x00, 0xEC, 0x00, 0x39, 0x39, 0x01, 0x00, 0x00, 0x00, 0xB4, 0x00, 0x39, 0x12 LT5 Message = 0x41, 0x61, 0x00, 0x00, 0x00, 0x4F, 0x54, 0x01, 0xAD, 0x80, 0x76, 0x7A, 0x00, 0x4B, 0x13 1990-1991 Byte 10 MSB must be set to 1 to tell CCM it is a LT5 (Tested and Confirmed with above messages) My final message was a pull from the 1995 ZR-1 I helped fix due to having a LT1 CCM. What I found interesting was the message: 1995 LT5 (I assume 94 as well) 0x41, 0x64, 0x00, 0xEF, 0x00, 0x51, 0x47, 0x01, 0x08, 0xCB, 0x14, 0x81, 0x7A, 0x00, 0x46, 0xFF, 0xFF, 0xAD Same size and length as the LT1. I no longer have a 94-95 CCM for test purposes.
EDIT #2. ECM messaging will be the same for 92-95 LT5s. they new at the end of 1992 the ZR-1 would end in 1995, so all remaining motors were built in 1993. If the LT1 and LT5 shared messaging in 92-93 that would make sense that the flag int he 94-95 CCM changes the whole message detection. I still believe there might be a flag in 92-93 but thinking now maybe not
EDIT #3: you said you would do a vanity plate: ZR NONE.. My Expanded Antique Plate is ZR ONE.. LOL
