I think the ECU mirrors the transfer functions and the table of tables to the RAM on startup and then reads them from the RAM. The ECU can only directly access data in the 0x0000-0x2000 range and to get it there it needs to perform several OPs, if the data is already in the external RAM section the...

I totally see now the first two cells being it's own reference address. The MAF has it too...that's really crazy to me.. I don't exactly know what ECU does with those own reference addresses. I think it never reads them, because it seems that ecu will work fine with anything written in those first ...

I think they can be CEL blink codes. Must to check... EDIT: They are blink codes. (pedal test - 5 times accelerator floor and CEL will blink the fault codes).

Ardustim is Arduino based crank and cam trigger signal generator. I i was understood right, it can produce only square wave output. But Motronic runs also with square wave, because it's zero crossing sensitive. It's one possible way :) Actually those ECU's will run with such ugly-looking crank signa...

For such a simple steup it's certainly provided some good data. Are you not finding that you have every DTC code under the sun stored in the memory? I have found a few more things so I am adding them to the excel file at the moment. Also discovered how to make a little text popup appear when you cl...

Your right, any undefined space needs to be filed or the file size will not be correct and obviously everything would be in the wrong place as there would be nothing taking up the free space. Its just a question of how the ECU treats an FF value, possible it just disregards it, which is why FF need...

Are you using charge cooler with your blower? And where your MAF locates? Bypass or blow out valves? Your symptoms looks like there is BOV installed, and blower blows out part of the metered air . -> less air goes through than MAF tells to ECU -> VERY rich. If you have scanner, look what's the realt...

Like that: http://ibb.co/kWeddk
It draws almost immediatelly graph look like this. Then it's colors partly other 16 bit cells, but if either byte of 16 bit address is read, i think it means whole address it is read at least once.

M50B25 -413 red label AFR surging at high rpm?*solved*
Hi! We have strange problem with M50B25 -413. Rev limit is raised to 7400, and when we run it on ~7000rpm few seconds (for example sliding at long gentle curve on ice track, or long straight) afr goes suddenly very lean, like 17:1 or leaner, and power is lost. Then it goes back to 13:1, when revs wa...

Hi! I did some research with those -413 623 vanos actuator dwell tables.

With 0...
