so the maro is doing its high idle nonsense again and i need to get this thing sold

93 z28

i paper clip scanned the car and got a reading of code 12 (normal)

and code 51 calibration error, mem-cal, ecm or eeprom failure

so my question is could this be the cause?

also if i yank out my performance chip will that have any effect on the car?

 

CODE 51
Trouble Code 51 indicates that the ECM sensed a fault in the MEM-CAL. On power-up, the ECM does a checksum of the MEM-CAL to ensure the MEM-CAL integrity is good. If the calculated sum does not match the sum in the MEM-CAL, the ECM will hardcode 51 and enter Back-Up mode, since the ECM cannot know where in the MEM-CAL the fault lies.
Code 51 is set when:
? the actual MEM-CAL checksum does not match the value in the MEM-CAL
Possible causes include:
1. Incorrectly installed MEM-CAL module
2. Defective MEM-CAL module
3. Defective ECM

 

i got that when i put my memcal in backwards. rined the memcal.

 

well its worked fine for months until now is the weird thing i pulled it all out and put it back in i think it may have been loose

i havent driven the car in about 2 weeks since i got the gti


tryin to sell the thing

 

Aw your selling my cars twin Hope the buyer cares for it like you do.

 

i know, im really hoping it doesnt go to someone who will ruin it

my dream is that some guy will buy it and tell me hes turning it into some ridiculous drag car and gives me his email so he can send me vids of it when hes done lol

and its gonna be hard giving it up because ive put so much work into it but it needs to happen
