I did ... everything checked out. I raised the rev limiter since I was hitting it, but that's not what this problem was. I also raised the Max Air.

I talked to Ken Kelly and got some hidden tables edited as well. It is some more TQM tables that aren't shown in my version 1.4. I will flash it and see what happens.

 

More info needed on your last post - Did Ken Kelly edit your file, or did you get an updated version that allows access to more tables?

I'm sure there are more tables / functions that we don't have access to. BenKey and I were just talking about an issue that we both have: Just after a flash file update with Edit, we both see high KR values and low timing. Then after the tune settles in some, no KR will show up and the truck runs much stronger. I'm thinking there is some predictive KR table, or a table that limits timing until the PCM has seen / learned enough to safely allow timing up to correct values.

 

I sent my file to Ken to get him to make the changes. I am having other problems besides the one talked about here. On a WOT run, I can see the timing being pulled as low as the Spark Retard Limit table allows it, where the timing should be going up ... not down. I'm hoping this will be a double whammy fix, but surely it won't be that easy.

 

Next time you talk / email him, ask if the next release or two will allow access to those tables.

 

Already did that ... waiting for a reply.

I was told the first time I asked that new found tables are always included in new versions, but I was under the impression this has been known about for a couple of passed revisions.

 

I, too, am interested if there are more tables we can access.

BigTex, I think I agree with your suspicions on the KR. I notice the KR settles down a little bit after the tune has some miles on it. Like maybe a PCM re-flash sets the KR sensitivity on high for the first XX miles or something.
But, my timing is always spot on (minus any KR, of course). I zeroed out the EQ vs RPM timing modifier and made my hi octane table ramp from ~26* at 3200 to ~29* at 6000+. If it gets no KR, I get the full timing. I guess if you guys are getting KR every time, the adaptive octane scaler could be pulling you down. Mine recovers from one KR event after one KR-free medium throttle acceleration event. I have my KR Decay (recovery) set at 95, but I'm not sure if this affects the recovery rate of the adaptive scaler.

 

You might try reducing some of the burst knock stuff. My understanding of the burst knock is that it looks for 'assumed' knock and predicts when it's going to happen. I changed all those tables trying to figure out what the heck was going on with my timing, but I think it's this mystery TQM stuff that I'm having problems with.

Hopefully Ken will hurry up and respond to my email and tell me it will be out in the beta version that's attatched ... but then .. this IS the real world we live in and we all know that Carputing isn't going to be that proactive about anything!

 

I turned of the knock learn on my last tune (I think). I need to really dig into the KR tables, figure out exactly what each one does, and do some testing. I think its going to be more trial and error since there are no good explanations for what the values actually mean.

 

I know ... that's the thing I hate most about EDIT .. you can NEVER get a definitive answer about any table. Even the most simple tables have debate around them for what they actually do and how they work.

Anytme you ask someone what they do you always get, 'I think', 'the way I understand', and other questionable reponses like that.

 

The tables you guys might be talking about are the torque shaft management tables, As I understand it, hahaha, they are only on the awd and 4wd trucks. They seem to be zeroed out on the cars.
I also remembering hearing the awd shafts can take about 1600lb/ft's and the 4wd closer to 3000, that's a lot of torque/stress.

Hey, flyer, did you recieve the PCM i sent you, if so , it's only to correct idle and drivability, since you have edit it's a good place to start for us to send files back and forth.

also, speaking of learning, i've seen some of the 03/04 trucks, take a while to learn no only idle, but get this, shifting, timing, tps, just thought that was kind of wierd. especially the downshifts.

later,
