nAst1: Progress and Concepts Thread

[robertisaar]

ok, here's a quick release with only the VE tables enabled for simplicity of checking the high RPM stuff. the unnecessary EGR related stuff is also gone...

i don't recommend running the BINs in an actual vehicle(well, the BFBD one should be OK, the BFUZ i just literally threw together in a few minutes), this is just essentially to test the code for the high RPM tables.

dave, you should probably adjust the rev limiters, IIRC, they're set to ~6000-6200 ATM, i wasn't sure if you wanted to see if it cut correctly or not at higher RPM(it should, since i didn't mess with that algorithm). i included an auto(BFBD) and manual(BFUZ) BIN so you shouldn't have to do any changing to however your sim is setup ATM.

also included in the ZIP is a matching ADX and XDF.

assuming all goes well, i'll be deleting the file after dave can confirm it's working as intended, so as to not have people running around on old, potentially buggy code.

You are making waiting for spring much harder... If you need a car that will run over your 6,400 RPM limit, let me know. I'm hopefully going to be able to run up a bit higher in RPM this year (7,150 RPM limit at the moment, and I tend to shift at ~7,100 at the strip), so I wouldn't mind testing this if once it's stable for vehicle use. I've got a set of the 96 DOHC heads and UIM/LIM already, and a 75mm N* TB and CAI in the mail. I've also got plans of getting an Ostrich and wideband this spring.

it wouldn't be very hard to basically copy the $DF tables for a LQ1 into the nAst1 mask...

and i've run the wife's car on it for at least a month now with no issues... however, it's a low RPM turd, so i'd rather just wait until dave can run it through his sim rather than risk an engine.

I left my sine/square wave generator in the shop at work, we were working on a pain field generator a few weeks ago.. haha


i'll bring it home Sunday and mess around with the bins and try to post results that night.

[robertisaar]

i'm confident it will work correctly, however, i can wait.

[Superdave]

Sorry for the delay, i had something happen at work that needed my total attention over the week. i'll do my best to test it this weekend though.

[robertisaar]

no problem for me....

i ran the GP up into the high table the other day, worked great except for two samples of the ALDL, it seemed off to me... only happened at ~5200 RPM though. you may want to check into that when you play with it.

[Superdave]

Well, i finally got around to it.. I wasn't able to get it to log past 6375. I adjusted the limiters as well as the ADX display limits.

attached is the log...


Did you seriously map everything in the disassembly? holy crap man.. haha

[robertisaar]

can you post the XDL dave?

i'm assuming you were only watching the RPM X 25 variable? i have a RPM X 50 inserted in place of another byte in the ALDL stream. when the ECM detects RPM above 5200 RPM, it uses that variable for the table lookups.
