PE rate and Delay arguement???

[Braciole]

I bought the course The tuning school beginners course.
One of the first things they tell you is to Change the delay to 0 and raise the enrichment rate per your situ, NOS, Bolton's, FI<etc..
I see alot of my friends going fast with the Stock settings 1.000 pe rate and
3000, 4000, and 5000 rpm delays???
Am I missing something???????
Please for the love of pete respond!!!
Thanks in advance

Here is a bump for you Mike.

[Chris@HPTuners]

on cars the PE delay time is calibrated to zero, so regardless of what you set your delay RPM to there is no delay.

enrichment rate sets how fast the commanded EQ ratio moves from the current EQ to the PE EQ ratio. ie. a value of 1 will move you instally to the PE ratio.

Like Chris said, they're apparently teaching you to mess with things that have no real effect upon how the vehicle operates.

The values for enrichment rate are step size of phi (enrichment ratio) from stoich toward whatever your PE ratio target is. If you're going from 1.0 (stoich) up to 1.25 (about 11.7 AFR) any value of 0.25 or greater will just get there in a single step anyway, regardless of time. A value of 1.0 is pretty aggressive. Only the truck really use this to slow the enrichment during a highway emissions test (US06) to avoid dumping fuel too quick.

Change it if you want, but it's usually just a placebo effect. You really need to have the injector values, MAF and VE right first before you can consistently tune this.

Thanks for the replies guys, another waste of time, just started to think I was going somewhere with this
