Code 51

Post by brindo »

Hi,
I have just fitted an NVRAM to my VT with a CJDN bin and the Engine Light is on with a Code 51?
Any pointers for a beginner on what to look for or what I have done wrong? I have checked that the NVRAM is sitting in its socket properly.

Thanks

Are you using the CJDN real time enabled bin? https://pcmhacking.net/forums/viewtopic.php?f=27&t=613

It has the program ID set to AA to stop the code 51 when changes are made to the calibration, if your using a normal CJDN for testing will need to change the ID to AA.

Hi,
I have tried to use the realtime CJDN bin from the attachment but the tables are jumbled using the $A6C XDF.
What else do I nned to do?
Thanks

From the brief look I had (AFR, spark and some trans tables) it all looks ok, was using the A6C XDF in the memcal ID tool and the CJDN_mod.bin. Maybe download them again, something might be corrupt?
