1HD-FTE tuning assistance
Posted: Tue Mar 10, 2009 7:14 pm
Hey guys does the 1HD-FTE, in particular the ute spec, have an overboost adjustment built into the ECU. If so what is the trigger point. Mine appears to boost up to near on 15psi which I am led to believe is factory standard. However I would like to tweak a couple more psi out of it but was wondering when the ECU will intervene. I know it's possible to alter the voltage signals to the ECu etc to fool it like the car guys do but then I assume the ECU will also alter fuel setting accordingly so a bit of a catch 22.
Is it possible to get another 3-4 psi into the engine pretty easliy without upsetting the ECU.
