View Full Version : B3702 Injection timing normal ECT cal table data issue - EfiLive vs HPT

Technical question for EfiLive Tech i guess, I've seen in my E40 and also in E38 PCM calibrations that the values for B3702 are as shown below, however tune file for the same vehicle in HPT shows exactly half the these values.


Now there is a handy calc over on HPT for calculating soit and eoit, which gives different results depending on which normal ECT data is used.


Is there a logical reason why the data in the table is different, when all other calibrations are identical?

Efilive shows injection timing as a crankshaft angle, HPT shows it as a camshaft angle.

Thanks that would explain it, but why only for normal ECT, when all other calibration data are crank shaft, the same as efilive?

Anyway, thats a question for HPT :)
