I got in a quick run in yesterday with the new map...it has been raining for the last week straight around here. Temp was about 72 and 95% humidity. It started pouring before I manged to get any more runs in.

I was having trouble getting the RR to read the LM-1..


3rd gear:

4th gear:

LV about 60 miles of driving:

It looks okay to me.

Me too!

Thanks again.

I may start trying to add a little WGDC between 4500-5500, looks like I am missing my target by ~0.5 psi.

The smaller pill is by far the best bang for the buck. 1st and 2nd gear performance has greatly improved and even 5th gear passing is much easier.

Here is a 3rd gear run, how does this look? Any suggestions to improve performance?

This tune is meant for an fmic. You only have a tmic which doesn't cool well.

Are you using a stock intake box and stock injectors? Your MAF is unusual.

You didn't log any of the important parameters so it's hard to tell what's going on.

This is actually my own tune, well it started off as your stage1 v3 I think. My intake is 100% stock down to the filter and as far as I know so are my injectors. Here is a more complete 3rd gear log. when you say my MAF is unusual do you mean my scaling or what was logged? I'm getting some low RPM oscillation when I start a run from 2k up until about 2.5-3k. I did a intake leak test and all seemed fine.

At sealevel, you should be about 230 to 250 g/s. Something is way off. Have you checked it with a WBO2.

You might be running too much boost at 5400 rpm.

My fuel is pretty consistent. Learning A-D is always less then +-2% and my WOT logs with my LC1 are mostly 1%-2.5% rich. I logged atmospheric pressure at 14.65.

I'll try a couple tenths at a time and see what happens. Does a TMIC require adjusting TD proportional and integral?

Not really. However, you are overboosting a little bit. First do a WOT log starting from 2000 rpm. That will tell you whether you need to reduce WGDC initial or try flattening the TD proportional curve.

Another 3rd gear run. I lowered boost by about .3 lbs from about 5.5k on.

How much does intake temp affect MAF G/S? I lowered boost from about 5.5k on by .3 psi and logged 1-2 more G/S but intake temps were 3° lower. I tried lowering boost an additional .3 psi and nothing seemed to change although intake temps were higher on that run compared to the previous run. I'm still only getting 212 G/S tops Also I noticed my boost keeps going above and below target boost by about .3 psi mostly in the 3-4k range. Is this an indicator that I need to flatten TD proportional a bit?

What does your IAT comp table look like?

At higher IAT, MAF will go down. I think mine dropped from 240 to 230. I can't remember though. However, at sealevel, it won't be 210. That's too low.
