nAst1: Progress and Concepts Thread

Interesting, thanks! I'll have to try that out.

Any idea when 1.08 will be finished?

[robertisaar]

as uninformative and dickish sounding of an answer as it is, "when i feel like it" is still accurate.

just haven't wanted to punch out the ~40 lines of code left to finish up 1.08.

[robertisaar]

notes for new version:

while doing some investigation for Ben, i discovered something odd: in earlier masks, pretty much every platform had unique mode 0 responses. these would normally be used only on vehicles equipped with trip computers(DIC/DIS) and some digital clusters. A and W body cars shared the same stream and is what all of the other platforms started using by the time A1 came around, except for J cars, which oddly enough retained at least some of it's 6D originated stream.

anyways, i guess this is only really relevant if you have a digital cluster(or a trip computer) in a J, L or F car, since A and W car digi clusters work out of the box. other platforms.... no idea. i've added in a patch for the L-cars to use their 87-90 digital clusters, i'll add the others in as necessary(or should i feel ambitious and get them done ahead of time).

otherwise, working on code for the previously planned 1.08 stuff now.

[robertisaar]

for 1.09, assuming i don't drag ass on 1.08 and just integrate it then, adding a D-MAP threshold for AE seems like a good idea.

any requests on 1.09?

Programmable boost-enabled output which could be used for meth.

Boost control solenoid control like in code59.

Maybe some other programmable outputs.

[caffeine]

Actually would it be easy enough to add the boost-enabled output to 1.08? Just something that provides switched power or ground.

[robertisaar]

boost solenoid/wastegate control could be done on the pin normally used for EGR3, much like how it was on TGPs. that's a PWM output.

as far as computerized meth control.... not sure. if it needs to be PWM, then possibly the AIR divert/shift solenoid A pin(though that wouldn't be possible with a 4T60E(unless you were running a seperate trans controller)) or the CCP pin(wouldn't be allowed on later 4T60E unless seperate trans controller).

if PWM isn't a requirement.... possibly the EGR 2 output.



perhaps another project would be to just remove all trans controls(except the TCC/shift light output) and force anybody running anything more complex than a 700R4 or 4T60 to use a seperate box(either aftermarket or the 7730TCM project), but i'd like for the 7730TCM to be 100% first. that would open up 3 outputs, two of which are PWM, along with a few digi inputs and 1 analog input.

so, just digital output? "when boost above xx kPa, ground, when under xx kPa, remove ground"?

[caffeine]

Ya pretty much.

[robertisaar]

what's the purpose behind that? i don't think you would be able to directly control a wastegate solenoid with that kind of scheme...

[caffeine]

For meth control. Wouldn't be as ideal as a controller but works as a simple control scheme. It would control a relay that turns on the meth pump basically. You could still change the amount of meth injected by changing nozzle size.

okay, now i see what you were saying.... for some reason, i was thinking 2 digi outputs instead of 1 digi in 1.08 and add in the PWM when possible.

deciding to do D-MAP threshold for AE at the same time, since it's a convenient place in the code to do so. the default D-MAP value will be 0 and there is no option to disable it. leaving it at 0 will act exactly as it always has, relying only upon D-TPS for the AE determination. setting to anything above 0 can prevent AE if MAP doesn't rise enough when D-TPS has risen enough to cause AE to otherwise be entered. if i had to guess, VERY little needed here to get the desired effect, like beyond 3kPa may or may not disable AE entirely.

this solves the problem of already being at a relatively large throttle opening(enough to where close to none or no vacuum is present) and opening the throttle quickly enough from there and having AE activate even though total airflow may not have changed enough to warrant it.

since that is now going to be in effect, it's possible that disabling AE while in PE will no longer be necessary.... i'm leaving the option to do so, but it would probably be wise to leave it enabled unless it proves to be a problem.

it's in the item notes, but the "general output" is setup by default to activate the circuit below the threshold value and disable above the value. sounds like what is needed for the T56 reverse solenoid. there is the option to reverse the situation as well. i'll have some commonly compared values available in the item notes of the scalar that way it can truly be "general".



i just have a couple more things to pound out, test them all and upload. not sure if i'll be able to deal with the wastegate solenoid/meth controls yet.

productive day.

[caffeine]

Sounds awesome. Now since I already have spark-cut in my current bins is there anyway you could patch my bin again? Since I'm assuming a general 1.07-1.08 patch may not work properly.

[robertisaar]

actually, the 1.07 to 1.08 patch SHOULD work for you... if not, can trigger it pretty easily.

when it comes to tunerpro patches, tunerpro looks at certain defined areas in the patches to see if it has been applied or not. if you change a patch after applying the patch, it sometimes thinks it's fully applied when it isn't. to remedy that, you have to change the first byte it looks at to anything other than what it is and it's detected as "not applied" again.



anyways, i was hoping to get this done tonight, since i seem to benefit from "momentum" when it comes to this type of thing, but i decided to go a different route on a few items for better compatibility, took up more time than i was expecting. my 1.08 changelog thus far, and what has already been put into patches:

spark cut rev limiter
MAP above which PE always enabled
3 step rev limiter TPS thresholds
general output in place of SSB/low coolant light
disable AE while in PE option, AE D-MAP threshold
8192 vs faster logging(need to verify if it's going to come out as 16,384 or 32,768. everything is indicating 32,768, but i haven't tested it yet)



so, the only stuff left to impliment is the new distance and volume tracker and if i can squeeze it in without deleting anything else, the wastegate control and second general output.
