Your seeing upshift torque reduction. If you look at the file you can see where you shifted just before the retard occurs. The RPM's drop and Throttle Position goes to 0.

I didn't see any shifts in his log where it dipped to -10, looks like the TCS kicked his foot off the throttle(hence the reduced TPS %) and reduced timing.

Look at frame 182. Just before the retard occurs it looks like he shifted. It looks like retard occurs when he gets back on the gas. What makes me think it's upshift TR is the consistant -10. USTR is the only table that applies to this that has values of -10. If he 0's that table he will know for sure.

His rpms don't drop enough for a shift, he's still in the same gear just the throttle being backed out reduced the rpms. If he shifted it should have dropped more than 100rpm.

I really don't think my TCS was on.. It was over a week ago so I can't be 100% sure.. I have the SLP TCS reverse module so it's always off (unless I make it default on which I don't).. BUT.. I can't be 100% sure..

The SLP module sometimes doesn't kick off TCS.

For kicks, enable TCS, log a file like you did earlier(try to get some tire spin) and see if it replicates the same info. Do you have a M6 or A4?

The "Spark Retard Limit" table value is set to -10 degrees and kicks in very breifly during upshifts and during what the pcm considers abuse mode. This happens all of the time with A4's and transgo shift kits, although it's hard to catch because it's happens for such a brief period of time. I always change the value in this table to +15 or +20.

I have a M6..
It's snowing here.. and gonna snow for a couple of more days.. I need to get another logfile.. I actually have about 3 other log files where I do not see this -10 degrees drop.. That's why this one interested me..

Look at frame 174. At 5535 RPM's he's doing 45mph. In frame 182 he's doing 45mph at 3548 RPM's. Seems like he shifted. That's also a lot more than 100 RPM's drop.
I'm not certain of what's going on, because I wasn't driving. But if it was my car it would seem the easiest test would be to 0 out upshift torque reduction.

It's very hard to catch the -10 drop during logging with a M6, but it does happen. I'll bet that's your culprit. On an A4 with a shift kit it will drop during a hard upshift and hold the -10 until you peddle it (I had this problem with my WS6).

Frame 166 shows where he is flooring it at 3892rpm at 30mph he is in the gear and at WOT until frame 168 where he hits 4475rpm and doing 34mph then in frame 169 I beleive he exhibits tire spin where the TCS reduces timing and the TCS kicks his foot off the throttle where his throttle position drop to 77% at 39mph and holds it there a little while.

Frame 181 looks the same, he's in a different gear and stabs the throttle to 100% where it goes to to retard limit of -10 backs off the throttle again to 60% until the tirespin stops and let's him go to 100% throttle again in frame 192.

Just a Lid....

Let me know what you think.. thanks.

Still waiting on this "proof" that GM have such a thing as a "Bad Gas Bit" and not a continual adaptive spark system you have told us that we are wrong about....whenever, no rush, I'll just keep reminding you until it appears, unlike the "warp speed" logs, this one won't go away.

Fetumpsh

Team ZR1, the 300+ users that viewed this thread are STILL waiting on your evidence that the LS1 PCM has a "Bad Gas Bit" that will switch the spark maps exclusively to the Low Octane timing table after excessive knock.....
You mentioned you even tested this on your C5, please either show the hard facts or please explain how you proved it or disprove what is shown on the EFILive website.

I know you dislike cyberspace B.S, you often say so, so please lets sort this out once and for all.

Team ZR-1

For one I never go to that scanner website nor will I,
2nd I gave my input as to seeing PCM into constant low octane table and by adding fuel PCM went back to hi octane, and lastly as I said YOU READ the GM documents as it states there is a bit flipped when PCM sees several constant knocks and common sense says they would use the low octane table for a bad grade of gas issues.

it would be stupid to think they have a low OCTANE timing table that would not protect the engine when there is a gas grade problem, esp for a $45,000 Corvette.

Again, not ALL models are equal and we all know Corvettes REQUIRE high octane where in other models it is suggested.

GM does not have content in their service manuals for nothing stating :

Add the specified amount of fuel. 19 liters (5 gallons)
Operate the vehicle within the conditions of the customers concern.
Does a driveability condition still exist?
Yes - Go to Step 6
No - Go to Step 29

So just how are you then going to see what I am talking about in action???.

Quoting from a Mechanics Manual, I thought you said you had technical info, not a step by step diagnosis guide for anybody who wants to lift the bonnet.

What do you think is going to happen to 5 gallons of 91 Octane when you stick in 5 gallons of say 98 Octane?? Yeah, Knock will reduce, therefore the adaptive scaler will 'eventually' get back upto 100%.
It was proven on a Camaro that adding fuel does NOTHING to the adaptive octane scaler value, only driving the car with reduced knock activity will get it back upto 100%. But then, you refuse to look at that evidence.

Still waiting on the answer as to how GM can run twin maps in cars that do not have a Fuel Level Sensor into the PCM?. That's gotta be somewhere in your Technical Manual

I don't believe it - he's got the OTHER foot in his mouth now!

Imagine a used car dealer telling you that they know how to put gas in ALL the different brands of cars they have on the lot, because they know how to read the manuals.

PS: Now I see why those EFILive people have to work so hard to just tell the verifiable truth. It's the "Red Convertible Syndrome" again... No matter how authentic and correct your car is at an antique car show, the red convert always wins...

The only saving grace is that you, and those that really know the truth, genuinely appreciate it, and we know that pop culture is just some idiot's impression of the facts. It is the same in the business environment.

Well, you can't teach those that don't want to listen, it's more for the benefit of those that do.
