Roms in excel format - hope this helps

micra_pete · 04-01-2005, 03:18 AM

hope this helps someone.

bunch of popular roms (the main map area) in excel format, hex and dec, good for finding patterns, maps, messing with multiplication factors etc.

take care with the vvl files as i reckon the ecu uses a few different methods to the normal ecu, and it may also need some more of the rom adding.

but its a nice easy way to look at the roms.

good for finding maps

sweet! thanks, did you enter this all in by hand or is there any easy way?

micra_pete · 04-02-2005, 09:50 AM

i wish there was an easy may, all done in the method used in my finding maps post.

also, im sure people have realised, but the hex number is wrong, ie the list from 8000, i just copied it across, just change the 8 to whatever number is needed

Btw Pete, this does help. I've got something from this I will post. Cool!

micra_pete · 04-07-2005, 03:16 AM

is the the base idle map for the b13?

if it is i reckon i found it too......

if not, i'll fire my laptop up later and get the address, see what you think.

glad its helping someone

Calum · 04-07-2005, 08:38 AM

No but do tell, I'll test that out.

exxd · 04-07-2005, 08:40 AM

I'll test too I have a great great great way to test.... ::kicks car::

micra_pete · 04-07-2005, 10:26 AM

baring in mind I don't own a sr20, and was just having a quick look last night whilst having a few beers

based on how it looks, and comparing to to the ga and cg values, if I could test the sr ecu I would try 0660

1500 1500 1500 1500 1500 1500 1500 1400 1300
1100 1000 900 800 800 800 1000

micra_pete · 04-07-2005, 10:28 AM

if its wrong its wrong, i'll continue having a look, i think i have found some other start up maps too, but i'll check at home

exxd · 04-09-2005, 01:58 AM

Hum so is this map based on temp? When you get a chance please post the other stuff too!

Calum · 04-09-2005, 08:25 PM

660 is correct, cool beans. One caveat though, it seems there are multiple "idle" maps. It only switches to 660 if your dead still. If your barley moving (like slowly creeping to a stop) its going somewhere else because my idle drops back to ~800. More hunting.

I believe Chris suggested 660 first, I just never got around to trying it, silly me.

exxd · 04-10-2005, 02:47 AM

Ya i wasnt thinking its my coldstart that is messed up. I think its the temp sensor. Anyone find the cold start maps?

eurospecs13 · 04-10-2005, 03:11 AM

Do you mean the injector start pulse width table, if so I believe it is at 0320.

micra_pete · 04-10-2005, 11:09 AM

calum i have a couple of areas to try, erm ignition idle, that sort if thing, i'll post some addresses tommorow.

micra_pete · 04-11-2005, 03:33 AM

right, baring in mind i dont have a sr20, nor access to any data logs, i've had a look, and i believe there are maps at the following location, they all seem "sensible" area's to try.

Awesome, is the base idle map @ 660 based on coolant temp?

micra_pete · 04-11-2005, 10:25 AM

i think so

Calum · 04-12-2005, 10:47 PM

I've been working out where the maps are based on the routine that calls them. Theres a bunch, but not all seem to have much in them. Its depressing how many maps there are. We need to start a comprehensive document of all the maps, where they're called, what they do if known, and whats in the code near them if known.

eurospecs13 · 04-13-2005, 12:00 AM

what exactly is the revised blast off temp
