Hi everyone, I can't find much about it so does anyone have any information about the idle tables that they are 100% sure about? I can only find their descriptions in one old post, and the poster wasn't sure if they were remembering correctly.
That post is here.

Even if that is correct, I am using Mazdaedit, and I have a total of 7 tables (A, B, C, D, E, F, G) Attatched is a screenshot of all of those tables unmodified

. Could anyone compare those to what they have, and help me figure out when each table is going to be active?

The issue I'm having is that when Vehicle Stopped + AC on + Clutch in or out the car does not respect the modified tables and instead appears to go to the factory idle value of 800+/-10 (I can't tell which table its using because the idle with AC on varies by slightly more than the 10rpm that would show which table its on). On my edited map (not pictured) I multiplied every value on almopst all of the tables to get to 950rpm when hot. I did not adjust Table E, which (as you can see in the image below) is flatlined at 500rpm. I think that Table E is part of the problem, but I honestly don't see how it can be a legit idle table. Does anybody know what it does?



Thanks

 

I did some tests and set each table to idle at a different speed, then drove around and idled in different conditions. Table A was set at a fixed 1500rpm, and each table went down by 100rpm through the list (I left Table E at its flat 500 though)

Stopped Clutch In 1200
Stopped Clutch Out 1200
Stopped Clutch In AC on 1200
Stopped Clutch Out AC on 1200

Moving Clutch In 1400
Moving Clutch Out 1400
Moving Clutch In AC on 1400
Moving Clutch Out AC on 1400


Ok, what I can see so far comparing the test to the tables.

A - ???
B - Vehicle Moving - All AC - All Clutch
C - ???
D - Vehicle Stopped - All AC - All Clutch
E - ???
F - ???
G - ???

I messed around with the E-brake, being in gear, the brake, reverse, AC, clutch and everything else I could think of, but I literally could not force this thing to go into the other tables.

Does anyone know what's up? I'm thinking that Table E isn't really an Idle table, and that each table has a near identical alternate for Closed Loop.

And could anyone cross-reference the tables pictured above with the AccessPort Tables?

Thanks

 

I have never tried to figure this out ...mainly because I've never had any issues after modifying the tables. I can tell you how I always modify them though .
If I want say 1000 rpm and the tables say 790,800 and 810 at operating temp ...... i make the values 990,1000 and 1010 . Any value at a colder temp that is above 1000 ...I leave as is . And I don't touch table 'E'.

 

I just established the final new base idle in the end cell and then just smoothed it in with the rest of the values depending on how it compared. The new base idle was fairly high on mine; 1125 rpm, due to having a race pulley system to get idle up high enough with the alternator charging around 13.5V. I also altered the final end temp cell some with the higher idle along with a cooler t-stat and fan temps. Is it right or wrong? It worked fine is all I can really say. Note that the Cobb maps weren't fully defined back then. I don't think it really matters using this method though other than I never used that tuning system and am not certain how well they correlate to each other.


So this was one stock map from the Cobb AP for a 2005 MT




and I just did this starting with a new base idle of 1125 and merging/smoothing it in to the existing values





and then on the other idle maps where the base idle was slightly higher I scaled the initial value off the OE difference and merged it in too

Cobb AP Stock 2005 map



Modified map ([810 rpm OE idle this map/800 base idle] x 1125 new base idle = 1139 rpm (new base idle for this map)
