Map tracing is cool!

YOU MUST TYPE THE VALUES IN ALL CAPS!

B13 (and G20) SE-R 91-93, S13 KA24DE 91-93, RNN14 SR20DET Map Trace Values:

RPM MSB - 4475
RPM LSB - 4474
TP - 4292

Timing map - 8D00 (S13 KA - 5th Gear - 8800)
RPM Scale (timing) - 8480
TP Scale (timing) - 8490

Fuel map - 8100 (S13 KA - 5th Gear - 8E00)
RPM Scale (fuel) - 80E0
TP Scale (fuel) - 80F0

----

B14 SE-R 95-97 (G20 94-97) Map Trace Values:

RPM MSB - 3472
RPM LSB - 3471
TP - 314E

Timing map - ED00

TP Scale (fuel) - E0F0

----

S14 KA24DE 95 Map Trace Values:

RPM - MSB - 3473

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.

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.

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.

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

...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!
