I am confused on which file to put in the the SD card? Do i add the C Rom txt file our the b00c-b01c txt file? Also has anyone tried to log ecutek with this? I order a 2GB card but it hasn't come in yet. I have an 8GB card but not sure if it will work.

If you useing a A00C or A01C then just put the c series logcfg.txt file in the root directory of the SD card.

if you have a b00c or b01c then you will have to substitute the ram addresses for the b00c rom into the logcfg.txt file for the older rom as each rom has different ram address locations for the parameters you want to log.

Has anyone else noticed that logging shows direct fueling only regardless if you have port fueling set in specified areas? Will the new version of Ecuflash correct it? Thanks.

I dont think that will be an "ecuflash" issue.

The logging just pulls the contents on the RAM address you specify in the logcfg.txt file then applies the scaling you set and writes it to the log.

If you getting incorrect log results its probably because the RAM address is incorrect the number type is wrong eg isfloat or databits 1 4 8 ect. or scaling is wrong for what you are trying to log.

[D-VO]

That's what I was thinking. It's a bit strange that I'm the only one seeing it though. The AFR is seemingly effected by the port injectors coming on as well. So it may not be an incorrect logging address instance. It's not the biggest deal in the world and I can live with it, I'm more curious than anything else.

@D-VO are you on about the fuelling not matching the PI Ratio tables?

[D-VO]

Correct. Its been doing this for quite some time now.

Thats weird i assume you changed all three di/pi tables ?

[D-VO]

Yessir. All three tables are copied over each other. I tried DL'ing the new RomRaider then saved the same ROM there then reflashed using EcuFlash to no avail.

Hmmmm well that me out of ideas

[D-VO]

Me too. LOL! It's really not a big deal since I was able to tune around it. I wondered if it was an error in the addressing for the B01C ROM. I asked @Td-d but he said it was good.

[Td-d]

I did? Chuckle... I'm surprised, since the fuel injection parameters are the ones I've not really developed since I pulled these roms apart.

I'll see if I can get you a whole set of injection related parameters, that way we can id the correction ones - will also help with defining it for other roms.

Which parameters are you using now (post all of the fuel injection related ones).

[D-VO]

I may have just made a mess of my question. Oh well. LOL!

For the B01C and from what I can log, all of these seem to operate properly:

Primary Open Loop Fueling: 112cc8
Primary Open Loop Fueling Additive: 112e98
Front Oxygen Sensor Scaling: 11fefc
CL Fueling Target Compensation A (Load): 11533c
Injector Latency_: 113e28
Injector Flow Scaling: 10ddc8
Injector Flow Scaling BRZ: 10dd94
(Not quite sure which one of these is being used)
Rev Limit (Fuel Cut): 10e5d0
GDI Flow Rate: 115e5c
GDI Pressure Multiplier A: 1121fc
Port Injection MRP Compensation: 110f88

These are the addy's I have for the Port ratio tables:
Total Injection Ratio Port Cold: 11258c
Total Injection Ratio Port Warm: 11272c
Total Injection Ratio Port Hot: 11265c
