Yeah - table and parameter addresses are correct - but which logging parameters are you using for injector fueling?

D-VO 09-07-2014 07:11 PM

paramname = AFR
paramid = 0xFFF89330
isfloat = 1
scalingrpn = x,14.7,*

paramname = AFR_CMD
paramid = 0xFFF8DBE8
isfloat = 1
scalingrpn = x,14.7,*

paramname = Fuel_System_Status
paramid = 0xFFF8DC26
databits = 8

paramname = Closed_Loop_Fueling_Target
paramid = 0xFFF8A6D0
isfloat = 1

; similar to STFT / 100 old paramid 0xFFF8A5EC
paramname = STFT_AF_Correction1
paramid = 0xFFF8DB8C
isfloat = 1

; same as LTFT / 100 Old paramID 0xFFF8A774
paramname = LTFT_AF_Learning1
paramid = 0xFFF8DB90
isfloat = 1

;paramname = Port Injector Base_Pulse_Width(ms?)
;paramid = 0xFFF89744
;isfloat = 1

;paramname = Fuel_Injector_1_Pulse_Width_4byteExt_E60
;paramid = 0xFFF887C8
;isfloat = 1

;paramname = Port_Injector_PW
;paramid = 0xFFF887C8
;isfloat = 1
;scalingrpn = x,0.001,*

paramname = Port_Injector_PW_Ram
paramid = 0xFFF887D8
isfloat = 1
scalingrpn = x,0.001,*

;paramname = Direct_Injector_PW
;paramid = 0xFFF887E8
;isfloat = 1

paramname = Direct_Injector_PW_Ram
paramid = 0xFFF887F0
isfloat = 1

Can you do me a favour and log this address, in conjunction with all the ones you are logging already:

RAM:FFF887DC Ram_Fuel_Injector_2_Pulse_Width

Td-d 09-08-2014 11:47 AM

And this one:

RAM:FFF8A038 Ram_Fuel_Injector_1_Pulse_Width_4byteExt_

D-VO 09-08-2014 10:16 PM

Thanks. Here's the log with the new params added: http://i189.photobucket.com/albums/z...ps5e169116.png

Those params look like they log the same thing no?

*EDIT*
Ram_Fuel_Injector_1_Pulse_Width_4byteExt_ is column H
Ram_Fuel_Injector_2_Pulse_Width is column F

Td-d 09-09-2014 03:03 AM

Ok, fuel injector 2 seems to be the same as what you're logging as port ( / 1000).

I may have found something else, if not the FI pulse width (which i will continue).

Multiply the FI1 values by 5.7602 * RPM * 0.00000012000001 and tell me what it looks like - I believe it's port injector duty cycle.

Td-d 09-09-2014 06:53 AM

Add these (along with the one's I've already put up):
RAM:FFF8A06C Ram_FI_Test_1
RAM:FFF8A08C Ram_FI_Test_2

Td-d 09-09-2014 07:00 AM

Are you sure you haven't swapped these two around, i.e.
Ram_Fuel_Injector_1_Pulse_Width_4byteExt_ is column F
Ram_Fuel_Injector_2_Pulse_Width is column H

@Td-d any update on MerpMode for BRZ? :)

Positive. Sorry about that.

And for the sake of double checking what I have on my SD:

paramname = Ram_Fuel_Injector_2_Pulse_Width
paramid = 0xFFF887DC
isfloat = 1

paramname = Ram_Fuel_Injector_1_Pulse_Width_4byteExt_
paramid = 0xFFF8A038
isfloat = 1
scalingrpn = RPM,5.7602,*,0.00000012000001,*

and the two new addy's you gave me:

paramname = Ram_FI_Test_1
paramid = 0xFFF8A06C
isfloat = 1

paramname = Ram_FI_Test_2
paramid = 0xFFF8A08C
isfloat = 1

Going logging in a couple of minutes. :burnrubber:

So tomorrow will arrive my OpenPort 2.0. I plan to immediately flash the latest OFT Stage 1 93 Tune (my car is completely stock)

From my understanding I can flash any of the tunes so long as it fits the same transmission and region as my car.. However to be safe I plan on using the same coded tune as my ECU

I presume I can simply read the ECU, back up my ROM and then flash the new corresponding rom and be on my way?

Td-d 09-09-2014 06:24 PM

Shady195 - yup, just pull your original rom, confirm the CALid, and make sure you are flashing the same CALid back.

D-VO 09-10-2014 12:24 AM

@Td-d: Have a look. http://i189.photobucket.com/albums/z...ps2c566cfe.png

Nothing as yet unfortunately, I think he's been incredibly busy lately. I'll check with him on any plans.
