It should be possible to figure out the correct scaling for this table. Most table references in Mazda roms actually define the "real world" scaling and offset.
For whatever reason, Cobb chose not to use them in all cases.
For example, here is a fuel table with Mazda's scaling:
Closed loop targets make more sense with the Mazda scaling, IMO:
Unfortunately, the dwell table is one of a few which use a different data structure with no scaling, but here it is with the same scaling as the fuel table. 0.00390625, which is used for about 40 tables, and also for Subaru dwell tables in 32bit ecus. (in ms.) Make any sense?

Been meaning to bump this. I made a spreadsheet to convert the dwell values to/from milliseconds.
This is the stock table.
This is what I've been running for the past few months.
This is the stock table.
Code:
1000 2000 3000 4000 5000 6000 7000 8000 9000 6.50 7.58 6.00 4.75 3.56 2.85 2.38 2.04 1.78 1.58 7.75 6.75 5.33 4.67 3.56 2.85 2.38 2.04 1.78 1.58 9 6.08 4.83 4.22 3.56 2.85 2.38 2.04 1.78 1.58 10.25 5.58 4.42 3.86 3.52 2.85 2.38 2.04 1.78 1.58 11.5 5.17 4.08 3.58 3.27 2.85 2.38 2.04 1.78 1.58 12.75 4.83 3.83 3.36 3.04 2.83 2.38 2.04 1.78 1.58 14 4.42 3.58 3.14 2.85 2.65 2.38 2.04 1.78 1.58 15.25 3.75 3.38 2.97 2.71 2.50 2.36 2.04 1.78 1.58 16.5 3.25 3.13 2.81 2.56 2.38 2.24 2.04 1.78 1.58

/\ Nope . Check out his spreadsheet - I'm going to try those d585 settings
Oltman - would you mind posting all the info you have on startup dwell . I still think startup is inferior with the 585s and wouldn't mind haveing another look at that .
Cheers

yes - have discussed this in another thread at some length . In discussions with oltman , it appears that startup dwell not taken from the dwell table above but is a separate parameter . And it would seem that the 585s should ideally have a lot more dwell at startup than the oems .

heh... maybe I should post this in the dumb questions thread...
There's a separate table for startup and we can't get to it in ATR?
In Protuner, you're using an "extended" editor to edit it?
Sorry ahead of time if I'm totally off base. I'm intrigued as I run the original BHR coils and have characteristics similar to others -- but it seems this is a very common "trifecta" and couldn't have anything at all to do with the coils given the severity of any one of the qualifiers.

As far as other factors causing warm start issues - sure . All i can say to your suggestion that the coils don't affect it is ...... try the oem coils back in there . You just might get a shock .

Protuner has access to all the tables - which is the correct table to edit is not easy to figure out however .
