In order for script.boost to work, you have to make sure you have SAE.MAP (Intake manifold absolute pressure) & SAE.BARO (Barometric pressure) logging turned on.

 

Thanks so much!!! SiC!

 

Is this the better choice for logging? Any feedback would be nice please

 

It's pretty much just a generic OBD2 data logger. Not much different from the other loggers out there. It has no Mitsubishi specific PIDs so you can't log knock. Right now there are no loggers that can log knock on an EvoX except for the Ecutek Delta Dash.

On the AP you can log knock retard but not knock sum. Knock retard is the amount of ignition timing that is different between the map and the actual timing. It compares the IGN map and your actual IGN timing and the difference you see is the knock retard.
Example: If your IGN map says you are suppose to be at 22 degrees advance at 200 load/7500 RPM and your actual was 20 degrees. You will see 2 degrees as knock retard.

 

On Pro Tuner its slightly different
we have values of .35- 3.52 for knock retard but actual degrees are different
im workin on interpreting exactly what it is

 

Most knock retard values I've seen were actual ign timing degrees, I thought the AP did the same but I guess not. Now you got me interested, I wonder what those values really represent.....

 

You need to log SAE.MAP to get boost to log. That is the way I got mine to work.

Boost logs in absolute psi rather than gauge psi. Max boost shows 36.91 psi and only makes sense when I subtract 14.7 psi from it making it 22.2 psi.

Is there any way to change that? What am I doing wrong?

 

Hey SiC,

Would logging SAE.BARO get the boost to log in psig? Mine is logging absolute and showing 36.91 psi.

Thanks

 

There's probably a way to change it in the script...I think its a script because its a calculated value right? I JUST got my Tactrix cable today so I haven't had a chance to play with stuff very much yet...just enough time to load some of Gunzo's revamped 93 Octane maps to my SST :-P ahahahahhaahahaha

verkion

 

Yes be cause script.boost is SAE.MAP - SAE.BARO. Which would be like 33psi - 14.7 = 18.3 gauge psi. If you do not turn on SAE.BARO, it will be SAE.MAP - 0, so that is why you were seing absolute pressure instead of gauge pressure.

BTW, there is no need to edit the script, it's already written correctly.

 

Thanks SiC. I did send you an e-mail regarding this with a log. BTW, I was able to get the LM-1 to log through PCMScan. The log that I send you was from a GSR with a TBE, TP, and AEM intake. Despite the AEM leaning the AFR, the car still ran pig rich at 10:1 AFR at the top end.

 

Yes I saw your log and compared it to my stock JDM log. It seems like you are hitting lower load cells than mine since the AEM intake has a larger diameter MAF housing.

You really need to take care of that pig rich AFR...... I actually think you are in the 9's but your WB may not support such low numbers. Bumping your AFRs to high 10's alone would probably do wonders for you. And I don't know about other tuners but I like to lower my ign timing on the upper RPM, especially if I'm running higher boost.

 

According to the script, it's BOOST = MAP - Barometric Pressure - 14.70

So...if you aren't logging Barometric Pressure then I'm guessing it's reading 0 which means your Boost is NOT absolute pressure...in fact it might be quite meaningless.

Turn on Baro pressure logging in other words.

[EDIT] I'm an idiot! I just re-read the script...the formula I quoted is COMMENTED OUT. LOL. SiC IS RIGHT. The formula used is Boost = MAP - Baro. [/EDIT]

 

LOL, I thought I was going crazy so you made me recheck the script

 

Those of you with big turbos. What load sites are you guys hitting? Are you running stock MAF housing? What values do you guys have for the boost settings. I'm running a red and it seems to run pretty close to stock peak load sites (220ish) at only 1 Bar or so. Is this correct?
