Howard Coleman Posted April 15, 2021 Report Share Posted April 15, 2021 like many i am very excited about the possibilities of Math Block. i started out with a couple of simple items... Temp out of the turbo compressor before the intercooler minus Temp within my intake manifold. GP Temp 1 minus GP Temp 2 a-b Front Rotor EGT minus Rear Rotor EGT a-b i do get logged numbers but they aren't accurate for either. 282 F as per logged GP Temp 1, 113.7 F as per logged GP Temp 2 should generate 168.3. the Math Block says 93.5 F i have searched the Forum and re-read the Help Section. my formula is a-b a being GP Temp 1 b being GP Temp 2 one decimal point. thanks for your help 9 COLEMAN April 8.pclx Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 15, 2021 Report Share Posted April 15, 2021 I suspect this is because the math block is performing the operation on the values in degrees C (changing units is purely a PCLink visibility thing, the ECU always works in metric units). If you want that differential value in Fahrenheit you will need to add a conversion to that equation. ((a-b) × 9/5) + 32 Quote Link to comment Share on other sites More sharing options...
