Re: P59 custom os for 1uz
Right now there are two tables, one for cranking VE and one for normal running. They are both big enough with enough resolution for almost any NA motor. The first group of 1UZ motors came out in 1989 so they were probably using an 8bit ECU. If that was enough to run them back in the day what the Del...

Re: P59 custom os for 1uz
Could you explain why 2 VE tables would give you more resolution over a single VE table that was twice as big? Also, why do you feel you need more than what the factory GM tables give you if you are not going above atmospheric? The primary modifier for the fuel system, the cylinder size, is a 16bit ...

Re: RMAC OBD commands
I'm sorry it's taken me a couple days to process all of this information and to find out how to use my OBD device. I am now able to type and send 010B through the BT serial port and see the 1 byte return value while changing the voltage of the map sensor, even when it wraps around from too much boos...

Re: RMAC OBD commands
That's so cool! If you feel comfortable sharing your code it would be fascinating to look at. Or even where you were tweaking the bin. Do you have any clue where the OS limits the ability to read the ram? I didn't really want to use it to change the calibration, but now that we know that is possible...

RMAC OBD commands
Hello, I'm looking through the list of OBD options in the 2088 annotated disassembly and I found this DC.B $22 ;Request diag. data (2 byte PIDs) DC.B $23 ;Request memory addr. contents (3 byte address) Is there a way to make an OBDLinkMX BT work with $23 and request the contents of the ram? Does any...

Re: Reverse Engineering 12587603
This may not belong here, your disassembly helped me verify some of the work I did today, thank you. First the MAP sensor scaling was multiplied by 4 in tunerpro, either xdf works for this. Then I verified that ~1.25V into the sensor maxes out the value in the data logger, it does. This means the kP...

Re: PCM Hammer - new ls1 flash tool
Thanks for the advice. It turns out I didn't write out the OS_FLASH_OPERATION or whatever it was before hitting send. I used a noisy DC boost converter to get 13.5 and bricked the box a few times. Took out the boost converter and flashed with no problem on 12.3V. So I have a 7603 now! Now I just hav...

Re: PCM Hammer - new ls1 flash tool
I finally figured out how to log in here! I just got an OBDlink MX+ and I tried to used lsdroid and PCMhammer without success. LSdroid did a full read and it looked good, everything looks good going to flash but at the last moment it says "flash cancelled". PCMHammer finds the BT serial po...
