boost timing retard ecueditor


Last weekend I have try to retard the timing with timing retard per boost with ecueditor and it dosen't work, anyone have already see that.            It's gen 2 ecu

Ya if your base timing is 40 an you put the number 2 in the area you want retarded it will only give Lil more than half a degree..... Also found that if you are using the boost ref table for tuning i found was better to click the box from %tps to +tps. The percent amount didn't seem to make sense how big the percent numbers had to be to make a noticeable change ... But when tuning in + the numbers made more sense that i was putting in and every number change was very noticeable the difference it would make.

the ignition retard maps look to be just a 2d map reference. I didn't find anything that denotes a wholesale addition / subtraction or if it is a multiplier. that said, the only reference I found is part of teh actually assembly language, of which I really don't understand. I can usually follow the vb code, but the assembly has no meaning to anyone that doesn't see hexadecimal in their bowl of Cheerios.

I've tried a few times, but I don't know what the logic is and the commenting in the code is often not correct or copied from another code portion and not relevant.  Petri wrote the majority of the code and unfortuantley is no longer involved. Justin does a great job or re-interpreting the code, but it is often difficult to follow, not having the original source writer on-board.

A description of the logic for "%" vs. "+" is below.

Completely mapped bike, then raised pressure. At 100% TPS full boost the mapping was perfect. At 30% TPS the boostfuel needed to be retuned - this is quite natural as with increased boost the pressure also raises much faster. This is a sample what it looks like with the current logic: 100%TPS maps, 8000-9000rpm: TPS:180 + BOOST:60 = total 240 30% TPS maps, 8000-9000rpm: TPS:80 + BOOST:60 = total 140 So 240 is what it should be, but 140 is way too rich. Alternatively if VE map is multiplied then the results more or less adjust according to the all motor base VE map. 100%TPS maps, 8000-9000rpm: TPS:180 * (1+ BOOST:33%) = total 240 30% TPS maps, 8000-9000rpm: TPS:80 * (1+BOOST:33%) = total 105 But like said this is entering a new territory for me and the current system works already perfectly. Its only a thinking process as if we use e.g. boostcontrol solenoid to modifyt the pressure then the system will not be operating on a fixed boost and therefore we need to find a linear response for the tuning regardless of the level of the initial boost the bike is tuned for ...

Have found that the timing does retard but it is in percent ..... And usually a larger percent number is needed to remove the correct amount of timing you want to come out. If I want 10% timing out I will out a number of 12 to 15 and then check the log to see what it actually retarded too. If you are putting in the number of degrees you want taken out .... Only like 1 or 2 you won't really see a change or notice a difference on Dyno because you are only actually telling it to take out 1 - 2 percent of the base timing number.

Ok i can see how that would happen, the main table for fuel is in %

Thanks :) just blindly used it as a deg

From what i found testing an tuning it doesn't matter what you check % or + the timing seems to always functioning as percent of the base timing map.

Sbr, have not tested ecu with timing light only going by the logs, Dyno an actions of the bike when running an seeing if i get the expected results from the changes made. Work a lot with many standalones and have a pretty good idea of what the motor should do when it has certain numbers in it for timing. When checking results with boost ref timing adjustments, I found in order to get the proper numeric timing I wanted and the actual function I wanted from timing changes, they needed to be done by percent. Testing/comparing changes made with % or + activated didn't change how the boost ref function for timing worked, seem to always be a percent of base timing map.

 tl, are you measuring the timing somehow or going by the logs?
