THIS!!! This just fixed it, THANK YOU! One table (reduction duration), changed back to stock, stopped my dead pedal. I cant thank you enough brother!!!

I agree, but I went ahead and just did a write entire since mine is already converted to SD.

I just did a write entire on the ECM and TCM, but no change

Actually, as I described in my very first post, the truck has the ?dead pedal? issue at the times I?ve mentioned, in the log I posted 😜

This is such a strange problem. Could my idle timing be too far off from my main timing table and cause this?

Somehow I deleted my response, but it was that I changed the three codes to MIL ON FIRST ERROR but no change

Even with the OS converter to 2 bar SD?

Im not tuning anymore, just trying to drive and enjoy it. It doesn?t have a MAF.

I finally got time to make some changes. Injectors should be scaled correctly now. Can anyone help me with why my truck has a "dead pedal" at least once EVERY time I first crank it up?

Each time...

Can someone shed any light on why I can?t scale my CYL AIRMASS in my spark tables? The field isn?t underlined like the RPM side is.

I?m sure you?re trying to help, but I?m not picking anything up but insults lol. It doesn?t make sense to me? if it did, I wouldn?t be here. Again, this is the product of ?my? combination of idle...

Yeah initially I had a bigger motor in the truck but pulled it due to a cracked head, and built this 5.3 for it. I could use some smaller injectors, say, something below 63lb/hr so everything gets...

I have, what I would say, several hours of driving and logging to get my VE tables where they are. I haven?t smoothed/interpolated much yet but idle has been dialed in. I fought a couple exhaust...

And this is a SD 2 bar conversion. Closed Loop...

I feel like I've went through at least 6 different idle tuning procedures, but I can't get this one to idle right. I'm NOT looking for a handout, but maybe you can find something obvious that I'm...

I just added two friends to the car and made a run. I heard audible knock that time with the more weight in the car. I'm running 93 Exxon pump gas right now. I am still working on the VE table...

See attached log and tune. WOT Boost is 13psi, timing is at 12 degrees, AFR is 11.3. All of my logs have SPARK RETARD logged, pulling timing. I've disabled BURST KNOCK. Why is it...

I've got some timing advance in this LOG that I don't know where they are coming from. Around WOT and less than 4,000 RPM I've got about 20* of timing, then after 4,000 RPM it settles down to around...

Gentlemen, you nailed it!! These "high flow" cats completely came apart and clogged the exhaust. I don't see how this car was running, period. I can't thank you enough for your help. :worship:

Supposedly installed high flow cats at DBR. I will certainly check that!

I don't have a latest tune since nothing has changed yet. I'm going to go outside later and try to get his wideband working with my scanner. I don't understand how this tune was supposed to be...

With all do respect, as I've mentioned earlier, I've tried 12 degrees. I've also tried single digit timing, but it's still logging knock retard. Timing hit the -'s and it still knocked some. If...

The car runs like a turd. I can hear an audible knock and it surges badly when it picks up knock/gets KR. I haven't checked the sensors yet.

Its logging KR at around 3700 RPM's no matter what timing I put in it.

Installed a 3 bar MAP (12592525), changed MAP LINEAR to 312.5kPa and OFFSET to -11.5kPa, and here's the new log. It's hitting 213kpa in one area. Isn't that 16psi??? The analog boost gauge on the...
