Timing Reduct Scaling

[Me78569]

So this is a fairly typical issue with hot tunes.   the ecm is overracting at cruise.  It is not a timing issue, keep fueling at %100 or near %100 in your tune until you are above your typically cruising psi.

Ok so no work around for it?

 

With just stock injectors and an HX I don’t know if I have the qualifying parts to justify a ‘hot’ tune but my beginning fuel % is 109 I think.

[Me78569]

no fix on stock injectors other than start and hold at 100% until ~5 psi or so.  or just make hte tune less aggressive in that 0-5psi area,

 

Also make sure you are not using wiretap at cruise.  that will make hte issue worse

Ok so I can adjust my 0-5 to 100% and then from there on ramp up quickly and that should lessen the cruise hesitation? 

 

No wiretap right now but will be soon. Currently at 

 

tps pump min 20%

Min pump tap fuel 0%

pump low boost scale 5psi

boost scaling 40

 

Should I adjust those? I’m trying to get to a point where I have a tow tune and a DD/scoot tune and that’s it lol

[Me78569]

try 108 from 0-5 then 107 from 0-5 then 106 from 0-5 until your issue goes away.  

 

those settings should be fine

Gotcha, thanks Nick.
