Your mapper also needs to understand that just because the voltage displayed at the ecu is say 13v, doesnt mean it will be 13v everywhere else.Viktor wrote:Well..
Im only going on what the mapper said to me.. if ECU mapped at XX voltage. then if you are running at lower voltage the pulses to the injectors wont be right.. sounds perfectly plausible to me.
DTA SW was showing 12.5..
tested under load at local garage and only 11.5-12v at idle.. but 13.8-14.1v when you blip it a little, wouldnt go over 14v when at 4000.
fitted new alternator and 14.1v at idle and solid at other revs also.
The ecu could be at the far end of a bad string of wiring which would affect voltage displayed there.
So you need to be sure all wiring is good, battery, grounds, alternator etc etc
