Ok can someone clear this up for me... I have an r33 gts-t with a few bolton's as such she runs pretty rich.
Solution: went and got an SAFC II, had it fitted and tuned... all good power band feels a lot nicer and fuel economy goes up a little...
Problem: Battery goes dead and the car feels nothing like it used to... Confirmed that the settings in the SAFC have held so it's not like it has reset it's self
Ok so my questions is this... when you disconnect your battery and replug it in after draining any residual power out of the car the ecu resets it's self back to bog stock settings as such when you crank the car over it runs a little off eg idle hunts a bit etc then after a minute or two it feels normal again... I have always been told that these ECU's are a self learning ecu but that they don’t actually store any settings... eg on long trips it will adjust it for better fuel economy and if you strap it the car will get used to be revving harder and using more fuel etc...
I had my safc stolen a while back so it has been running on the standard ecu. I am just worried that when I hook the new one up and get it tuned it will be fine again till the battery dies... should I disconnect the battery first then get them to tune my SAFC... or alternatively should I just wack it on get it tuned... then disconnect the battery, reconnect it and whack it back on the dyno to confirm if my suspicions are correct.
