Terminator Posted June 8, 2009 Share Posted June 8, 2009 When fitting a peak and hold driver, should the resistor pack be removed? It makes sense to remove it as the extra resistance will slow the driver down by reducing the current to the injector. To keep things tidy I want to replace the Resistor pack with the P&H driver. Just need confirmation I have got this right. Quote Link to comment Share on other sites More sharing options...
Terminator Posted June 9, 2009 Author Share Posted June 9, 2009 Anyone? Quote Link to comment Share on other sites More sharing options...
TLicense Posted June 9, 2009 Share Posted June 9, 2009 If it's the AEM peak and hold driver, then yes you would remove the ballast pack. I imagine it's the same for most others, but couldn't say for sure. Quote Link to comment Share on other sites More sharing options...
Terminator Posted June 9, 2009 Author Share Posted June 9, 2009 Thanks Tony , it is what I thought, but can't find any info anywhere. I could ask on the AEM forum, but I may never get a reply. Quote Link to comment Share on other sites More sharing options...
dandan Posted June 9, 2009 Share Posted June 9, 2009 Yes - resistor pack should be removed when fitted a dedicated flyback circuit like a peak/hold driver system. Does this PH driver have any software adjustment capability? In some ways the resistor pack is a bit of a crutch to make up for a lack of PH driver and was typical practice a decade or more ago for low imp injectors. It works fine though. However, the PH driver should help get those big injectors open a little faster Quote Link to comment Share on other sites More sharing options...
Krister Posted June 10, 2009 Share Posted June 10, 2009 (edited) Do not fit an AEM peak & hold driver. It will melt your engine. Why do you need one anyway if running under 1000cc injectors?

TLicense Posted June 10, 2009 Share Posted June 10, 2009 Is that guarantee'd? Some injectors under 1000cc need a peak and hold driver to get a decent idle... Quote Link to comment Share on other sites More sharing options...
Gruggs Posted June 10, 2009 Share Posted June 10, 2009 i've got a peak and hold driver on my 960cc rochester injectors. Needed to ensure the idle is smooth. Quote Link to comment Share on other sites More sharing options...
