MAF signal too high. any ideas?
Thought I’d do a few logs this morning to see what sort of timming pull I’m getting, fairly happy with it really, seeing 1’s and 1.5’s mainly, one 4 on cyl 4 in about 6-7 pulls to redline, but otherwise OK. ambient temp this morning was just 1 degree.
However, I did have a ‘’MAF signal too high – intermittent’’ fault code before I did the logs, so I cleared this code, then did the logs, and the code was back.
It’s an AUM engine with a stage 1 map, jetex filter from bill, and a 3’’ DP/decat. Peak airflow this morning was 182-183g/s on most of the runs, suggesting around 228bhp.
Any thoughts? I’ve heard of MAF too low, but never heard signal too high before!
