wat are you running for timing at 4000 rpm?

 

[SIKDMAX]

Ill have to check my logs.... running a tune from Malibu795.... who just did HGs.... LOL.

 

[SIKDMAX]

Table B0910 Injection Timing (C) showing 18.0-24.3º timing depending on my mm3.

Edit: Damn just looked and quite a difference from stock. Was therein my prob?

that's not terrible at 4000 rpm. I was expecting you to say 30.

I just wanted to know for the reference library.

How much boost?

 

[SIKDMAX]

No.. 24.3 is the max in that table. It is there though basiaclly for all of 3000 RPM... starting at like 3200 and moving down from about 80mm3 and on.. So 80mm3 @3200 to 110mm3 @ 4800 (redline 4200) is 24.3.... that whole lower right corner. Could THAT cause a prob?

Thanks for the help BTW Mike.... that McRat tuning class cant come fast enough - looks like I wasted a truck in the process though.

we really need a glow plug pressure transducer to plot peak CP's.

Ignition that is too advanced will really spike CP's with no added power, even a slight decrease. Things that advance ignition (requiring retard compensation) are high boost, high IAT,

I have conditional retard built into my tunes, one for IAT rise I think is important. I never see timing over 20, but then I am a bit conservative compared to many. .

Dammit....

Im in over my head.... I give up. To the dealer it goes.
