When I scan intake valve temp all I get is -40. I'm using an e38 and l76 with a Speartech loom and original tune supplied in the ECU. The vehicle was going into PE and had AFRs around 10:1, the only way I seemed to be able to get some satisfaction was to zero out all the open loop tables B0141 and B0146 and set PE only. I thought this could be due to the -40 intake valve temp as scanned looking up B0141 and B0146.
With B3618 commanded fuel says it is a commanded lambda yet it behaives like an EQ table where I command 1.12 and get AFR of 12.8?
Interested in thoughts, have the vehicle for a couple of days
