I upgraded the firmware once a while back. I will check and see if I have the latest firmware and update to the 4.1. Some are saying that you need to disconnect the input cable from the LMA-2 (the device that transmits boos, knock to my LM-1) inorder to get the AFR signal from the LM-1 to log on Evoscan. I have not tested yet and I hope that this is not the case. It will be a setback if it is.

 

I'm still wondering how accurate the coolant temp is... today I flushed my coolant out so it was a good time to see what temp evoscan says the thermostat opens. Well it opens somewhere between 212-214f (100-101c) going by evoscan. This seems pretty high to me...

I don't think there were any changes to this from .8 so this could be OT

 

Werent you using the updated forumula?

I changed this in my xml file, but then 0.9 went back to the old formula.

 

So what coolant temp formula do you recommend?

 

Well on .8 I was subtracting 10* but I must not have changed that in .9.

Looking at the evo manual.. Valve opening temperate is 176+/- 3. I'd assume the fan kicks on the same time the thermostat opens.. could be a problem with my setup I suppose.

 

I will try to find it. It is posted in this ecuflash forum somewhere.

I had it posted in DF forums, but in an effort to discredit evoscan so people won't review their knocksums using a DF, he called evoscan inaccurate and deleted the coolant temp formula I had posted. The formula came from another member.

I encourage all of my reflash customers to review the knocksums from my custom tunes.

TTP has nothing to hide unlike others.

 

I tested on the ver 0.8 and my pocketlogger and I found that the Evoscan is off. With the pocket logger the fan kicks in @ 190-192*. With the EvoScan the fan kicks in around 210-212*. That was with version 0.8. I have not tested the version 0.9 yet.

 

So AL is now saying that the KS results are wrong since the coolant temp formula is off That is his way to prevent people from using Evoscan to find out if his tune is knock prone or not. Does he not know that there are a million other ways to detect knock aside from Evoscan

 

Wow some bs, I swear that foo dirty so dam dirty. No other tuners have dirt like him on this forum. Too bad some cannot see the wolf in sheep clothing..

 

really... is that why you purchase Megan Racing exhausts and then tell EVOm that they are custom made by your 'fabricator'.

 

you mean like mormons? JK I'm a mormon, well - not really. This thread has gone astray, mods?

 

Mitsubishi Logger Alpha proof of concept code WORKS.. an alternative logger will be available soon...

Here is the coolant temperature correlation that jcsbanks posted from a 1G DSM ECU:

***EDIT: This is the intake air temperature formula***
-0.00000003166xxxxx+0.00001425xxxx-0.002490xxx+0.2143xx-10.279x+361.01
***

Here is the air temperature correlation:

***EDIT: This is the coolant temperature formula***
-0.0003893xxx+0.08056xx-6.5226x+315.73
***

There's no guarantee that those eqns are exactly right for an Evo, but they appear to be much closer than the eqns released with EvoScan. Copy them into the Data.xml file just as they are written above.

 

Sweet man thanks again

If anyone here has another logger how about comparing this formula to your other logger

 

These do work better.. they allow Evoscan to evaluate the data in a nonlinear fashion instead of a simple linear equation.. Unfortunately these calculations create interative loops and slow down evoscan a bit.
