DSMLink won't give you any of their proprietary disassembly and rom patches.

This is a group of people who have disassembled the stock 1g and 2g DSM ecu's:

I don't know how much it will help you, but you can download the software and source code for the DSMLink software from their website. But, as mentioned, it isn't their disassembly.

Wow, talk about bad. If that is the case then it is "weakening" spark by lowering current by decreasing charge time, right? When you combine weakened spark w/ retarded ignition you get blow out. (Ignition closer to TDC requires more energy to ignite the same charge)

Sure hope its not messing with charge time.

Hi Guys,

I havn't forgotten about this - just working on something else right now.

My only problem with continuing is deciding how to handle decay.

My preference is for _you_ guys to reduce the decay timer manually rather than building it into the patch.

Thoughts? Ideas?

Cheers
D.

i will be more than happy with just the patch itself!!!

Yes, let us reduce it. Time is of the essence!

a manually adjustable decay timer would be nice

Hmm... precentage and time based maybe? One map for precent of decay to ignore, then amount of time to ignore it.

I'm pretty sure its just one value. Just add the table to the list but leave it at the default setting so the user has the 'option' to mess with it.

I am working on some of the octane control stuff at the moment for those that are interested. I may have found a setting in there that wont allow octane control below a certain engine temperature. If this is the case it is very easy to disable this side of things by just raising the temperature high enough.

very cool. ...although can't that be done by making high and low octane maps equal?

Mattjin

Alot easier to change one number than hundreds, and you can put it back to normal very quickly.

The point is to attack the knock control from both ends. Eventually we have to meet up in the middle.

Alot of stuff is linked to the octane number. For instance, disabling the knock control reverts to zero octane and also with it, turns off the boost control. There is already an adjustment for what octane turns boost control on and off, so now it can be possible to keep boost control but not run the knock control. Working with the octane control also leads to knock sum (timing retard amount, as we have found), and eventually control of that too.

Speaking of which, has it been found already if there is a certain knock sum that must be met before octane reduces?

2 sucessive counts of 6KS will cause octanenumber to reduce.

Mattjin

Thanks, I will start to work with that and see what I can find. Did you find it in the code, or is it just a known thing?

Today I did some testing and found a few maps that work for certain with Octane control. Posted them in my 80700010 thread for anyone interested. So at least for now I can turn off octane control at certain amounts of load. I just need to track down the short term retard (knock sum). Sounds easy heh ;-)
