Quick Instructions: Using Nissan DataScan, fill in the boxes below with the correct addresses. Start map tracing. Thats it.

Got an SR20 ecu that you don't have the RAM addys for? Shoot me an e-mail with the bin from your ecu and I'll back out the correct addresses.

that looks mucho cool. wish i would have looked over your shoulder saturday to see it in action. i did see it from across the shop, it was cool looking seeing it move like it did

so calum with this software say i have a consult cable and a jwt ecu could you use the map trace save it and load that into a programmable daughterboard like yours?

Calum · 10-18-2006, 11:03 AM

No, if you just want to modify your JWT program just dump it via the consult connection and burn the whole thing to a daughterboard. See Calumsult, rom dump tab. I made that for extracting stock roms, but it will work on any ecu.

For the record, I think modifiying a JWT ecu (or any other brand) you own is great (much better than running a S-AFC etc in conjunction), but just straight copying an ecu you don't own isn't cool.

Back on subject, rom tracing is for tuning. Its a must have, way cool feature.

This might mean better b14 turbo program???

Calum · 10-18-2006, 11:51 AM

Need B14 CAS and TP ram addys. Working on that. Not owning a B14 to experiment with means waiting...

U12BBDreamer06 · 10-18-2006, 01:23 PM

man we need a b14 turbo car near you....

eric96ser · 10-18-2006, 01:55 PM

We are hoping to work on the B14 bugs in the next few weeks.

Octave236 · 10-18-2006, 04:29 PM

hmmm you should rewire the b12 like a b14.. then use it as a lab rat.

U12BBDreamer06 · 10-31-2006, 12:21 PM

Just bought!

Yellow4g63 · 11-06-2006, 06:18 PM

Yes Map Tracing is Very Very Very Very Cool

micra_pete · 11-07-2006, 05:28 AM

Calum, can you send me a b14 rom and i'll have a look too

Calum · 11-07-2006, 02:03 PM

Those are all B14 roms, one is a GA (don't remember which) and the rest is a SR. The addys should be the same between the GA and SR for this ecu, they're almost identical. All dumps were taken with the ecu on a bench with no cas signals, so you can see what the ram looks like with the engine off.

The 'live' directory has dumps of the ram (3000-3800), with the engine idle speed set to 1000, 1250, and 1500 rpm respectively (real car, not simulated). Just guessing, I want to look at these addresses first:

CAS
>>MSB-LSB
30D9-30DA
30ED-30EF
30EB-30EC
30E5-30E6
31D9-31DA
3273-3274
327B-327C
3294-3295
329C-329D
32A3-32A4

TP
30DE
3150
3214

I should get a chance to stick an ecu on my bench simulator this week.

i wish i knew what all this meant haha the computer stuff is so confusing to me

micra_pete · 11-08-2006, 11:26 AM

e-mail for you

Yeah, we tried 2000 rpm, but the car didn't like that too much.

hey calum that 370cc de maf turbo bin is that the working one

Calum · 11-15-2006, 06:12 PM

...and I've got the B14 map tracing worked out. If I remember to write it down I'll post it in the morning. Congrats to Pete for getting the rpm bytes!

jskyhawk · 11-25-2006, 03:36 PM

way to go PETE!

I just ordered datascan today, Calum I'll be sending and ECU on monday.

U12BBDreamer06 · 11-27-2006, 12:46 PM

data scan is awesome...but a lil too far advance for me...time to do some reading...
