Tuning OBD I 3500 (LX9)

[jmgtp]

I'm running the most current version of TP now, I had tried an older version a week or two ago and still had probs. Are you saying to try an older version with the adx file you posted?

Ben, the scans I last posted were from using the bin you had sent me. Are you saying I should try the bin that Robert sent and we'll build off that?

I have no idea why it has the data glitches or how to fix it. I wish I could use Freescan for data logging but that doesn't seem to work at all.

You can build off either but there is no reason for Robert and I to be doing the same thing on 2 different files.

[robertisaar]

attach the .ADX file that you're using to decode the datastream, there may be an error in it, especially if it's one that i released back when V5 was back in Alpha stages, the ADS->ADX importer was kinda flakey back then.

I just flashed the chip with the BIN that Robert sent, this is the datalog in TP format, excel format and the bin: BCFA modded idle data log.zip

As far as the ADX, the top of the TunerPro screen indicates the following txt: DF_v1.4.3.adx, which I believe to be this file here: DF ADX.zip
And I think this is the one that you had posted the other day but I could be wrong. I remember when i tried to load it TunerPro would crash, when I brought TP back up it said the df_v1.4.3.adx at the top but I couldn't get it to connect to my ECM until I loaded the DF.ecu file which is this one here: DF ECU.zip

[robertisaar]

well, here is the ADX you posted with a bit of a delay between send/recieve commands, should stop some of the crazy values.

now, not only is the checksum accounted for, but a delay as well. if there are still crazy values, it's between the ALDL cable and ECM. shouldn't be another module on the line causing it, since the connect command tells them to STFU.

[jmgtp]

TunerPro loaded the file without crashing, thats a good sign!
I'll get home from work around 530 and I'll make another datalog then. Hopefully without all the glitches.

[jmgtp]

It looks like the new adx cleaned up the data. Before it was flashing the red error signal about twice a second, now maybe twice a minute and I'm not sure I even noticed any data spikes.

So here is a new idle TP log, excel log and the bin. The data should be a lot better with almost none or zero junk.

BCFA modded idle data log.zip

Let me know how it looks. By smell, I'd guess its still a bit rich and the engine is smooth but not perfectly smooth.

[robertisaar]

no crazy data spikes AT ALL.

and yes, quite rich at all times, but engine speed itself looks to be quite stable at idle, MAP a little less so.

[jmgtp]

What do you guys think as far as tuning the idle further? It is idling well enough that I wouldn't feel like an idiot bringing it in for an alignment now, so if you think its ready for accel/decel/cruising tuning I can go get that done.

I know I'm asking for favors here. Appreciate all the help!

[robertisaar]

it looks to at least be idling well enough to be driven, although it will be rather rich until the O2 catches up.

[jmgtp]

I'm going off memory, but I believe once in closed loop the BLM and INT were both well below 128 - and I think that means it is removing a lot of fuel?
Any chance of getting another revised bin? Need to get this thing running right and only 9 days till emissions.

I'll gladly offer some cash to someone if they want to take on the job of revising bins when I send datalogs.

[robertisaar]

yes, low BLM/INT indicates that the ECM is removing fuel.

and i've been spoiled by my nAst1 tables, i don't want to deal with the factory VE tables anymore.

I have no problem tuning your car but I am not going to do it through this thread.

Alright, well let me know how you prefer. I assume email.

Do you need another datalog of idle for idle or is the last one I posted good?

If you want to do them in quick succession, without hours or days of lag between bin revisions/datalogs, I am available tonight from about 7-9 and tomorrow 530-9.

[SappySE107]

email works and I can start with the datalog you made of my stock file. Just have to play it by ear on times, as I am busy busy busy but going over some datalogs won't take too much time. I won't be able to dedicate hours though.
