I like it, would it be possible to use the listing from IDA which had been commented in the trace (Disassembler) window & add a few instruction ahead of the current execution && have the trace log to file . Great work on the emulator

Perfect this is where I was hoping it would end up, you board looks much smaller that the Denso one show here, this one needed a modified lid as the eeproms site quite high & the blue conector was also bulky; this will fit into the 1G case also. this was all powered from the ECU socket.

I can see the tuning code on the main 7M-TCCS work area, I must be blind, what is the work space for the tuning software called ? I have done c++ but dont have any usb libraries as yet.

Hi, Jon. good progress, just wanted to know about the board layout, size and where it will fit in the case, here in australia our 7M-G ECUs are twin PCB board unit. so I just wanted to know where this new PCB will sit and if it will fit our australian ECU's (I saw post #200 which shows the...

Hi, On the data acquisition side of this at what speed will the data be able to be read and written to the board & how many registers can be dumped at a time? Manuel

Hi, some good progress, good work guys Has anyone had any luck with the mines ECU as far as decoding, I have one here and dont know if it has its data & address lines crossed (making it harded to extract the true code), I wanted to see what changes they made to the code, the ECU is for the 1G...

I picked up this ECU today and the PCBs are Identical to my other 1G PCB the main differnence beeing this ECU has a Toshiba CPU T5891 anyone know what the A & N mean I worked out what D was. This would indicate the D151801-XXXX is from this family and not 7433 ?

Hi, I have a interesting ECU its marked as 645E A/T & Toyota part number 89661-529D9 There is an internal board which holds the CPU 2 * EPROM 27C64 and a TC156022AP (which is a PIA IC) plus the xtal have a few questions Just wanted to know if it was from a 7M the suffix for the chip is...

Jon, I see byte saving techniques, I wasn’t clear in my PM, the problem I saw was the way IDA handled / interoperates the instruction BRN, IDA looks at the following byte (after BRN) and converts that to a branch address (which is correct) , IDA then assumes that address in a valid...

This here is the code from the 7MGE and the code from the 1G ld #07h, $1Fh ; Mode control Register di ld #01h, $20h ; Port A Data Register ld #0Fh, $00h ; Port A i/o config ld #40h, $22h ; Port B Data Register ld #0FFh, $01h ; Port B...

Hi, Just pulled out my 1GGTE chip and was able to read the code, the code starts out the same as the 7M I will post up the files when I have cleaned it up. You said the 7MGTE A/T & M/T CPU code is different is the numbering printed on the chip the same? With the 1G A/T & M/T ECU the CPU...

contacted sheepdog but long gone no info available on the product.

I will find out if they still sell these & what is the cost thanks for the info.

Just found another emulator this one is for a 1G-GT ecu and needs a special cover to fit over the board, The item was sold before I could request a copy of the proms & better pictures of the chips used...

Just a few Questions. 1) the D151801 has 12K ROM is that 12Kbits or 12KBytes? 2) The numbering 7433 on the CPU, are we sure this is the cpu type, has I have done many searches & posted on CPU web sites requesting information but come up blank. 3) is there a mode on the 7433 where you can run...

Just found this interesting ECU which is a piggy back ECU running external RAM/ROM looks like an OEM but hard to say as can be copied to like OEM. http://www.toymods.net/forums/showthread.php?t=43434 any ideas ?

> In regards to the 117-93-764-41-005000 on your order These are the bits I am waitng for, they are the 64pin IC sockets, there was a minimun order of 13 but I only got 3 I suspect this is the delay, good news, they will arrive before santa

The diagnostic extractor you are making, will that offer any more info than the current error code/diag. system which flashes the LED. If the ECU uses the parity BIT for this channel data type, is there any error checking on this channel?

3P, Good work. I have a 1G ECU and it has the following markings D151801-9730 and below this we have 7433-1161, which would lead me to think its the same CPU just a different production batch? I am interested to extract the code from this to see if it follows the same coding as the 7M...
