V4 Autotune Meth log.
Just got the new 6-16 maps and the #16 firmware for meth installed and i went to do some logging.
First i did some spirited driveing at the high way about 20min to give it time to adapt then i made 8 repeated wots all exept the first logged exactly similar. What do you guys think how does it look? I think the Debug Byte 6 (aggres lev.) seems quite low??? Can i go more aggressive? Car is Full stage 3(Highflow race cats)+Vishnu meth kit MAP1 UT=14.5 IC=50 MAX BOOST 16 MAP2 UT=16.5 IC=0 MAX BOOST 18 AGGR. TARGET 2 OUT TEMP 58F Last edited by Ramppo; 07-02-2010 at 10:46 AM.. |

This has been a common question... can I make it more aggressive? The answer is... You don't need to. The Procede will do that all by itself. It just takes a few runs for it to achieve and maintain its aggression target. You'll see this happen after a few 3rd gear pulls. But in your case, you will notice that you are already bumping up against your maximum boost limit of 18psi. This is fine. Leave it alone. Even if your aggression target isn't reached. Because your ignition correction is already down to 0%. So the only way to make it more aggressive is to run more boost. And 18psi is already PLENTY on 93oct+meth. I don't recommend going any higher unless you run race gas+meth.

I wouldnt go any more...
Your already hitting practically 18 PSI. I expected a little more ignition though at the 5000 RPM mark. Everyone needs to realize aggression level of 2 set point and your current aggression level being less doesnt mean its"OK" to run 20+ psi cause its not meeting aggression level, we still need to remember the basics of what we are doing here.... and that is we are spinning turbos with inlets the size of a quarter, to 18 psi+ from a stock level of 8 PSI; That a ton of boost for these turbo's. Keeping that in mind, On stock Turbo's I wouldnt Push past 18 PSI from a reliability stand point of the turbos, especially for those without intercoolers as you have to over-spin them because of the pressure drop. 20 PSI once or twice with full bolt ons race gas meth and intercooler... sure. |

Thanks for the replys! I admit that i do not have a lot of knowledge regarding this subject but i do want learn so i dont cause unnecessary load to my engine and the only way to do that is by reading and asking
I understand that 18psi is plenty and i would not exceed that not untill i got RB turbos i was just wondering the low aggression level and did not realize that it take more than 20min hard driveing + 8 wots to reach the final value. But like i said thanks for the replys i appreciate it. |

Put "final" in quotes because the tune is always adjusting itself, plus or minus, to adapt for your conditions. The only time it will stop moving is in cases like yours, where you impose a upper boost limit. Which is a good thing to do with stock turbos running on pump gas. Shiv |
