But I probably wouldn't start by opening up the software and looking at the dropdown where the MAT Corrections parameters reside. I certainally then wouldn't see one labled "MAT Correction value." And I wouldn't open that dialouge window and see that I can input a value from 50-100% to change the scaling of the ideal gas air density corrections.
fastivab6tg25mr, I might try changing from "Corrected" to "Normal correction" and see if that helps.
Otherwise, the only solution I can think of for an MS1 would be to switch "CLT-related density", use IAT, over-ride the RPM taper, and enter a map which is inverse of the normal correction map at half-scale.

I had two AIT sensors at one point. The second under the driver side fender, with a little computer fan blowing on it. I'd use a relay with some RPM + TIME? (I can't rember) to trigger from one to the other.
doesn't really help, still gets hot under the hood...the issue is the aggressive code that pulls way too much fuel at any temp abouve 85°F
I don't have a copy of TS loaded on the PC that I'm typing this from, so I can't check right now, however I don't believe that the MS1 has this feature.

same function as the MAT corrections table in MSII and MSII.

Us old-schoolers don't have none of this hoity-toity percentage scaling.

does anyone have an idea of what im doing wrong? do i have to reload the firmware in order for the clt corrections to turn into mat corrections? i was trying to use the lil green ball as a reference like the box says but it is still following clt values instead of the mat values i set it to.

MS1 user here. I was able to remedy the hot starting lean condition using the coolant related air density table adjustments table and it's working pretty good now. Thanks for that help.
Question- When constantly in boost at the track on a very hot day in Miami, my AFRs were getting leaner in boost, presumably due to high AITs. Is the MS1 pulling fuel due to high AITs just like on hot starts? Can I compensate for or prevent this?

well on the MSI you have a decay to turn off the CLT-Based corrections after X rpm, probably set around 2500RPM, so the MS starts pulling fuel again based on the MAT. you may want to increase that value a little.

FWIW, my car was pretty dialed in with autotune to run 12.2 AFRs at 140kpa and 11.5 at 170kpa between 4000-7000RPM.
And I was reading about 13.4 AFR at 6-7psi in the same RPM range on the hot track with AIT's above 105*F. Too much difference when AIT's go up.

I had that problem - and tried to change it to MAT correction, but it was still reading from clt temp. Had to go into the .ini file and change the line:
[CurveEditor]
curve = clt_IATCorrC, "Coolant corrected Air Density, see Settings", 9
topicHelp = airdenHelp
columnLabel = "Temp", "Offset"
xBins = IATCTemp, mat <==change this, previously 'clt'
yBins = IATCorS
gauge = matGauge <== also change to this if it doesn't say this already
Hope this helps!

Just tried the above, found the curve editor in C:\Program Files\EFIAnalytics\TunerStudioMS_beta\config\ecuDe f\MSExtra format hr_10.ini manged to save it but the iat correction table is still showing coolant corrected. What am i doing wrong? Surely it should be iat corrected?
Thanks in advance for any help.
