Tscompusa I made that untrue in this rom.

1) The 3d Table has both axis completely independent of the main timing and fuel tables. I did it this way so resolution could be applied to off boost where it usually is effected the most. Feel free to adjust the table anyway you choose.

2) I setup the kPa vs load table in a way a 5 Bar sensor would be setup since the map vs kpa table exists to set the sensor up from volts to a kpa value. In this way as long as the sensor volts vs kpa is right the kpa vs load table doesn't need to really change. It could really be scaled up to a 10bar sensor if one wanted to. I think the possible limit of the kPA value is 2000 or 20bar.

 

Ill test out that final rom tomarro.

 

Just curious, but why does the last column in the kpa vs load not have a 1:1 ratio. Will adjustment to the right side of the 2D table ultimately affect where on your fuel/timing map you fall at certain boost levels? On the old SD setups, increasing your load column typically made your afr richer and pushed you farther right on the maps.

For example (4-bar): 400 kpa / 400 load (leaner?) vs 400kpa / 445 load (richer?)

 

Well in my experience the way the car reacted once it was in boost was never really 1:1 the fueling of the car seeming to desire more load once it was in boost which is why its setup in that manner.

And your right the right hand column like the VE map directly effects load/fuel. The way it works in this rom is the same more value pushes you to the right of the maps.

 

Got it, now I have mentally mapped how everything is working in this new setup
I agree, keeping it 1:1 over 100kpa never really worked for me. I usually scaled it for 100kpa = ~115 load & 400kpa = ~445load.

Great work, can't wait to get the car put back together to start actually testing

 

I'm thinking about abandoning the idea of patch the live map versions. After reviewing the code and process I'm just not comfortable making the live map correctly setup for this rom. I'm hoping someone else will come in later and patch that for me after everythings said and done.

 

Ziad is the man for live mapping I'll ask him if he'll have a look at it when he gets time

 

Posting up the Evo 9 rom which like the rest of them is all alpha testing haha

8859 Variant Rom:

well i've been using this rom for about a week now and all is going well, even done some full boost runs at it was only fractionally leaner then the previous map. One thing that I have noticed it now and again the car seems to cough, anyone else notice this?

 

You mean the stutter thing? I noticed that when i tried the 9563 rom myself quite awhile ago it only happened for me at really low load points it seemed and pretty casual rpm like cruise with a slight hill.

You can check your IPW or try the stutter fixes already defined.

 

its not a like the normal SD stutter, its just a single one but it is at low loads, I've tried the second stutter fix and its still the same will try the 3rd one over the next few days, in the logs that I have there is a small dip in the IPW by 0.5ms when I think it is happening

 

Is your load going below 19?

I noticed when on my SD rom if the load went under 19 or so it would go into injector shut off mode and the car would do really stumble for a second.

 

it does in places but not the area where i think I'm getting the cough, also those areas are showing constant IPW too

 

Hmm maybe its an async table thing not enough fuel in some places?

 

I must be doing something stupid or missing something, but I just Dl'd the 885 variant and I don't see any of the 3d tuning tables. The 3d index and lookup tables are present, but under the 'speed density tuning' table, I only have 2d tables which aren't giving me the correct scalings and such.
