exciting news: P13 fuel table research for P28 =)

[TheTempest]

Howdy,

I've been doing my own research into reading the unreadable fuel tables from the stock JDM P13 ROM.

Update: 1-8-06
LowFuelTable

This looks extreamly close to what it should be. I still dont have decimal places because I can't remember how to write out decimal places, but this is pretty darned close.

Update 1-2-06:
LowFuel Table

The btm is a tad rich, lol...and the top looks a bit rich too...but that looks much better

Here's what I've gotten so far using my own program to parse through the data.

Low_Cam Fuel tables


High_Cam Fuel tables



Here's what Uberdata does after I make some mods to a script:
Low_Cam Fuel tables

High_Cam Fuel tables


What doesn't make since to me is that the RAW data in the ROM has the 1st two coloumns nearly identical...without the multipliers...So I'm really confused about that...

Odviously it still has a lot of work to be done, just thought I'd share what I have so far. If anyone has any insight, please, let me know.

Thanks

edit:
sorry for the crappy screen shots, imagestation doesn't blow up the picture really that big, and the JPG doesn't look to great. What it does show, on the btm section, is a nice block of numbers that look great, just the offset needs to be adjusted.

hope you find a solution, i know this is drivin you nuts Brandon

Yes sir. It sure is. At this point, I'm concerned with what the WIKI says is the fuel table...isn't. Even with modifyers the inital values are all the same. Also, how does uberdata display a max of +-653353? That's a DWORD in programming, yet the table is only one byte per entry (0->255). Even using one byte against another byte as a multiplier that's still only 0->65025, not +-653353. Eh, anyways, I'm still researching.

Also, the WIKI has this 1x40 table that it says is ??multipliers...what confuses me, is the P28s' multiplier table is only 1x10 (which makes since, 1 multiplier per column)...

edit:
What I need to know is how the P28 import routine really works.

well aren't you a smart little bugger. Why not just manually input all of the values you found? You'd have to talk to ppl like john cui, blundar, gimpy, and maybe blake warner if you could find him. I don't think any of us have gotten that far into the address locations of the ecu and how they're processed because the p13 map is already out(a little bit was missing out of the hi cam fuel map tho)

[TheTempest]

Any information on how they got some information out would be great. I'm continuing my research and will post updates as found.

I've tried emailing bigwig about how he does some things in uberdata.

I have the raw P13 map, I'm just trying to format the data so the P28 can read the fuel and ign tables.

Thanks for your input so far.
