I did a little playing around today with the higher-end of the MUT table to see what little tid-bits we can log. Some of them may only work with the auto transmission models, but there is no harm in adding them. These will replace some of the incorrect MUT addresses that came with Evoscan.

Brakes On - MUT AA : eval = "x bit 16"

Transmission in Park - MUT B4 : eval = "x bit 64"

Transmission in Reverse - MUT B4 : eval = "x bit 128"

Power Steering - MUT B8 : eval = "x bit 4"

A/C Request (Switch) - MUT B8 : eval = "x bit 1"


The only unusual thing is that the A/C Switch works backwards. 0=on, 1=off. A shout goes out to Deepnine for the suggestion to look in this area.

How can two sperate items be logged with the same MUT request?

i could think of a couple of things those could be used for.

AC switch could be used for starting/stopping logging

Brake could be used to stop fueling to counter throttle hang.

Mattjin, do you know how "B8 bit 1" compares to "4A bit 16"? Is it two items logging the same thing? (I previously had 4A bit 16 down as a bit for logging the AC switch.)

Also, I've tried to pull together a MUT requests page over at the wiki:

http://evoecu.logic.net/wiki/MUT_Requests

Updates/corrections would be very welcome; I've already incorporated the additions from this thread, and the updates to the LTFT/STFT formulas from the thread about them. I'm trying to keep it limited to just stock MUT requests, not "math channels" (purely calculated stuff) or common mods; we can probably create pages for those as well, but it would be nice to have a sort of "implementers guide" to what requests are out there.

wow, brakes on... that's cool!

MUT 4A is none of what it says in Evoscan, it is the Purge Control Duty. You will notice that trying to log 4A as it is, you get random results which it should considering it is a duty signal. Hence the hunt for the real locations. I noticed that MUT A0 and A3 are identical, so there is another spare MUT to log things on. One of the others I am hunting for is the FPR solenoid.

The Brakes item was a good find IMHO. Very useful for anyone who hits the track to see what they are doing.

While I was searching I also have been looking to see if the ACD selection alters any of the bits, seeing as how nobody seems to know of the link to the ecu is an input or output. I did not find anything yet.

Another thing I posted elsewhere but might be easier found here... MUT 54 seems to log the amount of Acceleration Enrichement (increasing TPS), and MUT 55 logs the Deceleration Enleanment (decreasing tps). I am pretty sure there are two more MUTs for delta throttle +ve and -ve but I will double check first. It might even be delta MAP so I have to check it.

Mattjin, thanks for those (and the explanation); I dug up the thread acamus started about the purge solenoid MUT value, and I've updated the wiki page with 4A, 54, and 55 (with just a straight 0-255 percentage formula for each).

MUT 54 brings up another inconsistency in what we've been using in Evoscan too, though; I have 1D as accel enrichment, but as an airflow/rev output. Do you know if these are related?

I already found that BF is the last MUT that can be logged, but for interest sake I attempted to log C0 onwards. Result : Instantly shuts off the car when you do the CTRL-SPACE.

MUT 12 I also found is High Range Coolant Temp. Interesting that they split Temp into 2 RAM addresses. Do you have a formula for how to read this? What is the max temp that can be read?
MUT 1E is a long list of bits that can be logged. Tied into ALOT of subroutines.
MUT 4C,4D and 4E are related somehow to the LT trims
MUT 58 I have as being related to accel enrich somehow.

acamus

I believe MUT_12 is used for warmed up calculations, this is why 81°C is minimum seen for this MUT, it is not more precise than MUT_10 actually it is same value once 81°C is reached, it is only clipped from below.

The max value is 126°C, if you open 88590015, mrfred has ADC/°C scaling table (Coolant Temp Scaling) in, I have seen it in all ROMs that I have come across.

I have updated table above for some more values.

Mattjin

126C sounds about right. From what I have figured out the auto trans maps go up to 124C, and it would not surprise me if they use the same sensor.

Updated my collection for bank 2 trims (V6 related)

MUT_7a-MUT_7F - seem to be continuous/non-continuos monitor status bits.

Namely MUT_7d is binary negate of OBD_Non_Continuous_Monitor_Completion_Status
