Bump. Come on guys I need a hand with this. I'm stumped. Any input would be great.

Here is just a quick log from today after I put the original tune back in it. Could a bad MAF sensor cause false KR?

Hey man, sorry it took so long for the next log. Here is a log with 6* of timing pulled across both the low and high octane tables. The truck ran kind of funny and made a couple of strange sounds....

I'm sure the plugs are probably the same. They are either the NGK tr5 or tr55, I can't remember. I considered changing them next. I pulled one from each side when I first discovered the KR and they...

Oh and I don't think I have any exhaust leaks. I'm not hearing any audible knock, but I don't have a trained ear for KR. Every time I have heard it in the past, it sounds to me like an old Ford 7.3...

Here is the log after I changed the knock sensors, harness, cleaned MAF and added 17 gallons of 93e10 fuel. There is a pattern as to where the truck is KRing. It is always bad between 1400 and 3600...

Here is a log after a SMALL timing reduction.

Here is a log after an octane booster.

Hey guys, just recently bought an 04 Silverado rcsb with an lq9, 224 230 cam, P&P 317's, built trans, 3600 converter, 4.11 gears, eaton limited slip, polished throttle body and an under drive pulley....

I thought so. Today I jumped in my truck over lunchbreak and drove around and the truck was at operating temperature, the trans was around 120-150 and it would NOT lock up at all. I let the truck...

Hey man, is there anything in that tune file that wouldn't let my converter lock up on a cold start. The past few days it has been fairly cold between 33-50* out and my converter will take a while to...

Ok, I think I got it. So when I hit the tow/haul button and the converter spins freely, do I slowly pedal it up to the certain speed and then nail it, or do I just nail it regardless of where the rpm...

Hey man, tried the tune out and WOW. It drove amazing. No idle issue, no surging, nothing negative so far. The only thing I am concerned about is the whole overdrive thing. What exactly is overdrive...

Gotcha. Like I said not trying to aggravate you, just trying to learn myself. I will mainly be using your file for comparison. I want to be able to honestly say I tuned my truck and it made a...

Looking at the tune you sent me. Why so much WOT timing? 28* seems like a lot to me. Maybe not? Not trying to piss anyone off, just wondering. I run 93 non ethanol gas.

I have an 07-08 truck intake and TB. I think it's an 82mm. I also have the torque rush box for it.

Will do. Thanks man.

It's for a 224r? I'll give it a shot today when I get out of class. Thanks man.

Man I sure do hope so. It's not fun getting waxed by a stock 4 door in my cam, longtubes, nnbs intake and tb, built trans, 3600 yank converter truck..

No, I had a guy local to me tune it.

Any luck on that config file? I have been logging a little. No steady state just plug in fire up and go to the grocery store kind of logging.

Ok, will try to log as soon as possible. Yes I am still using the stock injectors. The idle issue is when the truck is started, hot or cold, 90% of the time it dies. When shifting from drive to...

Ok. This is the tune I paid for locally. I have not yet logged any data or started adjusting anything yet. I am trying to gain all the knowledge I can beforehand. I am having an idle issue with it...

I am looking for a tsp 224r tune that someone has made so I can compare it with the one that is in my truck now.

Thanks,

Erik
