WOT PE set point - how low can you go?

[spoolboy]

How low can you set the WOT PE voltage?

I think it depends on the vehicle. I had a Trackhawk freaking out about being at 1.5v one time. If you were driving right at 1.5v it would do something really weird and miss bad.

I regularly do 2.0 on Trackhawk and Hellcat without that problem though. I have been wanting to try 1.8v and seeing downtime but haven't.

I have seen Hemituna say going down to 1.6V is low enough to cause problems because of cam movement.

The pentastars will allow 1v but the NA boosted hemis (NA from factory) don't like much less than 2v.
If you find you need lower than 2v, it is best to do open loop full time.

and how can you get it to stay open loop the whole time ?

Change the ECT to go Closed Loop. I do this a lot of the time on the non Hellcat OS with boost and it works great.

Just set it to 2.5v. Message me for a tune
