Thread: Turbonator SBEC Codebase

  1. #41

    Re: Turbonator SBEC Codebase

    I'd like to try out your T-SBEC, but have questions.

    First, I've been using Dcal 1.20 and 90MP_MTX_3-Bar_Sw-Bst_+40b.bin. Its also been a year since I've played with my cal. It has been running fine for me until somebody suggested that I'm a running outdated cal.

    I did try Phospate 2.0 last year. The timing and fuel didn't meet my needs and didn't seem to like dcal making changes. No matter what I did, it never worked. Hence going back to my 90MP_MTX_3-Bar_Sw-Bst_+40b.bin setup.

    When looking over TSBEC's asm file, I'm completely lost. I don't see the where the flags are to be set. Nor do I see a program to comply the ASM file once I've choosen the flags for my setup.

    Is there any documentation on using TSBEC?

    Re: Turbonator SBEC Codebase

    You really need to get MP Tuner to fully use the templates as intended. You can do it the CHeM2 way, but you'll lose the ease of MAP scaling. And, you'll have to do some manual editing od the .asm to get it to compile the correct template.

    MP Tuner is the top sticky in this section...

    Thanks, now I have a good starting point to relearn.

    yeah, mptuner makes it a snap to set up the cal.

    its a little klunky with the AFR setup (ie, matching the map fuel tables to the green line in chem2) but it works.

    Re: Turbonator SBEC Codebase

    ok i PMed you but i thought i would list it here for all to see too. I have seen that others have problems with it idling high, but i think there is a code problem and here is why.
    When i burn the Stock cal from the stock cal repository NOT TSBEC, it idles fine, but the file won't open right in MPtuner
    But when i burn a stock cal in TSBEC the car idles at 2500 rpm and wont come down.???
    Is something in the spark scatter idle messed up?

    Re: Turbonator SBEC Codebase

    r2.3 now posted: Removed some forgotten '.org' statements that caused overlapping code. Would not give a compile error, but made bad code that would (oddly) still run a car - poorly. Also added a new template (A596). It's VNT template, nearly identical to the A415 except for some overboost constants.

    Anyone that was having trouble with v2.2, try this update. v2.2 definitely had problems...

    DL'd 6 times, but no feedback? Is this a 'No news is good news' type of deal I hope?

    Well one of those was me just because I wanted to look through the code. Curiousity may be a good number of the dl count.

    maybe i missed it, but was this ever updated for 2 bar or is it still only 3bar?

    Re: Turbonator SBEC Codebase

    No, it's fully operational now (where's that Admiral Akbar smiley?). You can edit it in MP Tuner just like the other codebases. You can make a 4-bar if you want too.

    I have templates for the 'major' SBEC versions - 2.5 T1 MTX and ATX, Mopar Perf, 2.2 VNT, and the 2.5 HT. Both the VNT and Turbo boost control code is in there, so you could pretty easily make a 2.5 VNT if you were so inclined...

    Re: Turbonator SBEC Codebase

    As soon as I can confirm that my T-SMEC dwell code is working correctly, I'll add that to T-SBEC also. See the T-SMEC thread for more info...

    Re: Turbonator SBEC Codebase

    Doh! Found some errors in one of the VNT tables. And, the flag bit I was using for the Charge Temp Sensor appears to be used already. That might be causing a fuel issue. I'm updating the code now...

    Re: Turbonator SBEC Codebase

    question... this actually spans all of the turbonator lines.... LM, SMEC and SBEC....

    how are all these code mods effecting the overall speed of the code/main loop?

    we are already rpm limited with the stock code with nothing else running in the background.

    just curious.

    Re: Turbonator SBEC Codebase

    I don't think I've hit the wall, yet. At least not on the SMEC/SBEC. The main loop has a counter that makes it run every 11ms, no faster. I haven't seen any evidence that this counter is maxed out, though I haven't looked lately. Maybe I should.

    Even still, all that would mean is that the A/D channels are loop behind in their updates. I can see it being a problem, but not a huge problem. There aren't many of these engines that make power much over 6k.

    If it becomes a problem for someone that spins that high, the simple solution is to start removing some of the subroutines we don't really need - EMR, Purge, EGR, some of the diagnostics, etc.

    Re: Turbonator SBEC Codebase

    if you get a chance, lemme know what the potential rpm headroom is of a smec and sbec.

    2.0L dohc can rev that high and make power up there and some folks are going to 2.0L custom cranks in their 8v setups.

    Re: Turbonator SBEC Codebase

    Actually, the 11mSec isn't going to be the problem. The problem might be in the length of the distributor interrupt routine. That routine has to run everytime a blade passes thru the main HEP (there's a separate routine for the sync pickup). It runs on both rising and falling edges, or 2 times for every blade, 4 blades per rotation, 1 rotation for every 2 crank rotations. So, at 8k rpm, that routine has to complete in less than...

    8000 rev/min / 60 sec/min = 133rev/sec X 2 = 267cycles/sec / 4 blades/cycle = 66.7 blades/sec X 2 edges/blade = 133 interrupts/sec or 7.5mSec to complete the routine. It's a pretty decent size routine, but I think the SMEC and SBEC can handle it.

    I should be able to figure out a way to datalog the time it takes that routine to complete. Not a priority, though...

    Re: Turbonator SBEC Codebase

    So on the first page of this thread there isn't anywhere to download the newest version??? Maybe i'm missing it somehow but i guess i'm thinking it'd be like the SMEC thread?

    Yeah, I took it down casue the last build was bad. I haven't posted the latest becuase I haven't confirmed it's working correctly. Care to test it out?

    Re: Turbonator SBEC Codebase

    I went ahead and posted v2.4. My only concern at this point (other than it not being tested at all) is whether or not the RAM locations I chose actually exsist or not. They are in the proprietary PSD chip, so I have no way ot identify the memory map there. However, I think they should be OK (otherwise I wouldn't have chosen them). So please feedback to me if the Turbonator options don't seem to be working (specifically anti-lag and the staging limiter).
