Turbonator SBEC Codebase

[ShelGame]

i had a few minutes to try it today. it starts if i put a slight amount of pressure on the gas pedal and will idle if i do the same. if i let off the gas the rpms will go too low and it will stall. i put the low rpm pumping efficiency down to around 65% and got it to run w/o being stupid rich. it will rev fine but quick blips of the throttle will cause it to caugh and hit 16.0+ afrs. i am still getting that slight high pitch squealing noise from the SBEC area that i dont get if i have a stock bin on there....


I've suspected i have a bad AIS for a while now so im just going to order a new one and go from there and see if that helps anything and try it over again and get back to you.

OK try this one. I think I had some bad cal data in the transient fuel tables for the 2.5 cals (2.2 were OK). Only the templates are updated here, not the .asm.

havent started the car since sunday and the battery was dead...not sure if it had to do with tsbec or not?

Anyways, I swapped in my new ais and tried the new template. The car fired right up and idled with no changes other than injector and map scaling. Had some lean hesitation but it got much better once it ran for 5 min or so. Overall it seemed pretty happy! I just gotta actually tune it now to get it better. Hoping I will be able to take it out soon to see how it does under boost/load but for now things are looking pretty good. Ill try to start it in a day or so and see if the battery hasnt drained

[ShelGame]

Awesome - keep me posted.

I'm going to go ahead and put v2 up on the front page so everyone can find it...

V2.7 Now posted...

Tried to start the car after it sat for a few days and the battery was dead. It doesnt die if I leave it sit with a stock cal on it..

[ShelGame]

I wonder why that would be?

[AzShadow]

No idea...ill retry letting it sit with a stock cal and confirm

Stock cal in the same computer? Or different stock computer?

[AzShadow]

Stock cal on the same computer with an ostrich and converter

Took the car out to the track wed and it felt good all night, no missing, afrs were good, everything seemed to be happy. Ran a new pb of 14.26 @ 94.7 on 13 lbs of boost that dipped to 10-11 lbs on the 2-3 shift. Still have the battery drainage issue and cant comment too nuch on part throttle performance but wot was good lol

Rob, I have a few questions about Turbonator:

- Does it work okay with factory and aftermarket scan tools (eg: Snap-on MT2500, OTC, etc.); such as the PID data displays, actuator tests, etc.?
- Has anyone else experienced the battery dying issue like AzShadow?

If no one has told you lately, I truly appreciate all of the hard work you do for these cars -- and especially the SBEC crowd.

Thanks again, sir!

Regards,
Chuck

It should. The DRBII Routines and the address MAP are unchanged from stock.

Do you still have the AIS issue? That itself could be running the battery down.

I confirmed the AIS thing myself this past weekend (I was using the 2.5 Auto template). Not sure what is causing that, though. I have to go thru the code with a comb and figure out why it would be running the AIS after key-off. It could be quite a few things...

[ShelGame]

OK, this could be the problem.

;   LE6DA:  jmp  LE6C7          ; dead code?

This is a line in the shutdown routine. This is the routine that powers down the SBEC when the key is turned off. I had originally assumed the line above was an error on Chrysler's part becuase, as far as I can tell, this line of code can never ever be run. The same call is repeated twice. So, this one will never be run as in-line code either. But, the shutdown routine is the same in every single SBEC and SBECII assembly I have bothered to create (T1, TIII, V6, Mexico, etc.) - including this line. So, Chrysler must have put it in for a reason.

Take off the semi colon ";" in front of this line in the .asm file and see if the AIS issue goes away. I'm going to do a test with my R/T tonight and see if I can make the AIS cycle the same way in the T3 code by taking out the line above.

Yeah i still have the ais issue. hopefully i will be able to try this out in the next couple of days.

[ShelGame]

I have no idea how it could be the issue, but you never know. Let me know if/when you get to try it...

Just a TSBEC cal for my Dad's van, this was the first time i got it to run good on the first try. The other times it would idle at 2,000 RPM, the AFRs right out of the box were perfect at 11.8 with 10 psi, now to hook up the boost button SCI cable to start datalogging and Tune it

On a side note the AIS motor would click for about 30 secs after shutting it off the key

Only for 30 seconds? Then it stopped on it's own?

Forgot to mention but last time I had the car out it was idleing really high but only in gear...had to get on the brakes so I wouldn't break pit speed limit

Yeah, and im not sure but i think it stopped doing it at all, I will check again today
