well that makes since with the turbine, I never ran my car for great lengths of time doing that so dont have any data. I will have to do some experiments at the track with the different setups, i will try 25psi peak-taper to 19-20, then try 25psi peak-taper to 23. thanks guys.

 

I see what you are saying with the TBEC. that is a valid point. TBEC does carry over when you let off the throttle.

Do you have another solution for climates like mine, where the temps change drastically between seasons?

I've weighed the options I know of and I'm willing to put up with a small spike if it will allow me to not require a re-tune every season.

 

ya its better not to have to retune, a spike wont hurt afterall you do have boost limit table to protect you for big overboost spikes.

 

Here is what I have for this Evo 9. TBE w/stock cat and Injen intake w/uicp. Top part is the logged boost, 2 byte load, load error and WGDC correction. Bottom part is BDEL+BCLO and TBEC. 4 back to back logs on 91 octane gas. All numbers are averages.

I want to thank razorlab for the tip of setting BCLO to 200. It makes math so much easier

 

That looks like my rom. Thanks Naji. And thank you razorlab for the tip, it definitely makes the math much easier!
