I'd like to know how to use "step retard" fonction in turboedit.
I know it's a better solution than using linear retard, but it's quite more difficult and longer.
Does anyone want to teach me about this ??

 

Whats to teach...TurboEdit does it for you

 

Hum, so could you explain how it works ?
I mean what TE does when you enter the value ?
I don't really understand what is the sense of "the degree of boost to step accross your ignition map".
Sorry, these question may be silly, but I'm French and I'm not enough fluent in English to understand how "step retard" works.
thanks

Instead of a degree per pound, it steps down a user defined increment per 3 pounds. It follows your VE curve a better... Also gives more power by being much more aggressive.

If you don't know what you're doing fuel wise, I would just use a linear retard.

 

In fact I already use linear retard, but I wanted to use step retard because it would be more efficient.
Thanks for the replies.

 

ok
Could you explain to me how to do that with turboedit, I think I missed a great part of the information :

13.5 AFR while NA. 28 degrees timing at boost/NA transition peak power production. Timing retarded by 1 deg / 1000 RPM on top side of RPM band after peak power production.

12.5 AFR from 0psi to 3psi. retard 0.25 degrees cumulative by 3psi (i.e. 0.08 degrees/psi)

12.25 AFR from 3psi to 5psi. retard 0.75 degrees cumulative by 5psi (i.e. 0.25 degrees/psi)

12.0 AFR from 5psi to 7psi. retard timing 1.75 degrees cumulative by 7psi (0.5 degrees/psi)

11.5 AFR from 7psi to 10psi. retard timing 5 degrees cumulative by 10psi (0.75 degrees/psi)

I have a wideband for the AFR, but I want to upgrade my ignition timing, starting with this type of values.
