Finally sent my SGII to the company for the MINI specific tuning and put it in my N18 CM ALL4. It has a VIP Intake and a JB+ set to the 1 o'clock position. I use 93 octane only. 28k miles, no other power mods.

Currently I am watching boost, intake temp, water temp and timing.

Seems like max boost is 13.9.

Water temps max at about 215

Not much on intake temps yet, but I think within 20* of ambient. (Currently around 50* F ambient)

Timing is the one that is all over the place. Anywhere from 0 to 50-60 (I think...moves around a lot). Is it showing positive or negative timing? I am not seeing a minus symbol on the gauge...

Your input would be greatly appreciated...am I watching the four most helpful things? Am I in the ballpark? If not, what should I be looking for?

Thank you!

 

I like to keep an eye on the battery.

 

I watch water temp. and battery. By the time the idiot light goes on for the temp. it's too late.

 

 

I find it useful to log the data then look at it later.

 

Thanks everyone! Why watch the battery? I don't see the correlation between that, boost, intake temps, etc. But, this is exactly why I am asking!

For timing, what should I be seeing (or not want to see) on those full boost runs?

As for data logging, I assume you are talking about using something other than the SG?

Thanks again!

For data logging I use DashCommand or ScanXL. Torque is also available.

For timing I look for steady or slightly increasing numbers during WOT. The actual number can vary but generally you're looking at single digit numbers.

For instance when I had the JB+ I normally saw about 4 degrees advance now with the Manic tune I see between 6 to 8 degrees advance on Map A.

Drops in timing during WOT especially 3 degree steps can be signs of timing being retarded which could be a sign of knock activity (but not necessarily).

One thing to note is that you are only monitoring cylinder number 1 and not the other cylinders.
