Explained: Scangague II (SG2) vs Torque Pro (TP)

[ptommo59 Senior Member Find all posts View Profile Close ptommo59]

Hi Toopy,

Have you tried Spencer's Injector codes in this link Scangauge II (SG2) Injector Feedback Values (1KD-FTV) - FOUND - Toyota Prado How To's, Technical Information & Reviews (pradopoint.com.au) as they may have carried over to the early 1GD and I assume you might be interested in monitoring these as you get higher up in the kms. If you are getting a response compare to what you are seeing in Techstream at idle and if OK sorted if not we can try to see if its a different PID code or formula issue.

Cheers Phil

I've just spent the day having another look for the 1KD (I came in because footy is about to start). I believe I may have found the injector feedback values. I may have missed them years ago as I think I was using the wrong equation. I landed on (xx*20/128) -10 which seems to work. I originally assumed 8-bits, but it appears they could be 7-bits in the 1KD, your sheet looks like 8-bit precision.

So if people are interested, can they please try the following and report back for injector feedback values? From what I can see it matches pretty close to Techstream, however, I can't run both simultaneously (Techstream loses connection with ECU).

TXD:07E021AD
RXF: 032280000000
RXD: 4808
MTH: 00C8 0080 FF9C
NAM: VI1 (injector feedback value #1)

TXD:07E021AD
RXF: 032380000000
RXD: 1808/2008/2808
MTH: 00C8 0080 FF9C
NAM: VI2/VI3/VI4(injector feedback value #2, #3 and #4)

I can see the other values nearby are also the other readings, but didn't have time to figure out the equations yet. So I'll save that for another day. The 80 on frame 07E22 (4008) is likely the Injector volume feedback learning and the 58 on frame 07E23 (3808) appears something to do with the volume.

Any chance you can share this for torque pro settings?
Thanks

Wow this is great thank you (pray)

Any chance you also got the dpf sensor pid's?

Haven't seen anything on the DPF side for the 1KD but the 0178 EGT sensor codes used on the 1GD apparently work.

Thank you for this.
This is also part of the standard pid's so they exists.
I'm more interested in the pm accumulation ratio.

Also wondering how do you extract this so fast?
I'm trying to work my head and Chatgpt and creating a convertor from scangage to tourque... And it dosent seems so straight forward or I'm missing something.

I have been working on trying to find the PM Accumulation Ratio for the Euro5 1KD/2KD with another member from Europe as the 1GD (2138) version does not work and currently waiting on some more data from him. Also found those engines have an oil pressure sensor not in the early 1GD so that may also be of interest.

I have been working on reverse engineering Toyota PIDs for quite a while, so have most I have located online or created from data logging in spreadsheets so cut and paste to here (and other forums/FB pages).

Scangauge to Torque is not very difficult as Mode/PID and OBD Header map straight across from the TXD.

You do need to understand the different KWP, CAN and UDS messaging structures for Mode 01/21XX PIDs vs Mode 22XXXX PIDS and single verses multi-frame messages as these affect the make up of the RXF, RXD and MTH and how they map across to the Equation in Torque. Min and Max Values in Torque only affect the displayed gauge range which is not applicable to a scangauge so will be dependent on the PID type and range you want on screen.

As an example this is the guide I made to do Mode 01 code generation and conversions (for 21 the response changes from 41 to 61)

	CAN ID		DATA BYTES
Byte	1	2	3	4	5	6	7	8	9	10
Bits	0-7	8-15	16-23	24-31	32-39	40-47	48-55	56-63	64-71	72-87
RXD Hex Bit Offset Position	00	08	10	18	20	28	30	38	40	48
Universal Single Frame Request	07	DF	01	PID
Response Single Frame Hex Start Byte	07	E8	0x	41	PID	A	B	C	D	E
Response First Frame MultiFrame	07	E8	10	xx	41	PID	A	B	C	D
Response Remaining Frames in Multi	07	E8	21	E	F	G	H	I	J	K
			22	L	M	N	O	P	Q	R
			23	S	T	U	V	W	X	Y
CAN OBD II	ISO	15765-4	24	Z	AA	AB	AC	AD	AE	AF
			2z
Unified Diagnostic Services (UDS)	ISO	14229
			0x=03-07	xx=08-FF

You should also be aware that the scangauge RXF has formatting information that affects the Torque equation, plus if you are trying to convert an x-gauge from the Scangauge websites with a RXF starting with a letter (for Toyota it is generally a C) don't bother as the PID value in the TXD and RXF have had an offset applied so it won't work if converted straight across. The offset is not a fixed amount and must use a lookup table or formula embedded in the scangauge to correct the information being sent to the vehicle.

Edit: Have you done a Torque Scan of all your engine 07E0 Mode 21 PID responses? As if yes that would be handy for me to look through for the PM Accumulation and Oil Pressure info, so could you post or PM them to me.
