SHUT THE FUCK UP AND GO TRADE IN YOUR CAR FOR THE EXACT SAME CAR BUT IN A DIFFERENT COLOR, THEN PARK IT IN YOUR MOM AND DADS DRIVEWAY!!!

AGGGGHHHHHHHAIRBALLLLLLLLLLLL

FUCKIN MINI BIKE TO THE HEAD GUIDO STYLZ!!!

HP tuners does not offer this, but with a simple fixed resistor and a switch I can set him up to pull whatever timing he pleases by forcing the IAT sensor voltage to a predetermined value. Then you just set the timing you want to pull in the IAT Spark Advance Correction table.

Guys, this is the point where you tell everyone that you are out on felony bail and felony probation then proceed to bitch-out and say you don’t need trouble and try to shake hands even though you are the one that started it…

^The above really happened.

@SSmokinn SS

keep running your mouth Pete. Instead of having 75% of this forum hate you, why not just go all the way and make it 100.

you were fine by me early summer, now your just a little bitch that talks alot of shit.

99% i like Red Rubin

[psi2high]

I will pull the plugs on the car just so every one can see that it did not run lean

@kdubs

Andrew, you should really really ask the owner of the vehicle what happened before posting shit like this. I don’t apreciate being woken up this morning by somebody who does know the full story telling me your running your mouth.

#1 My truck did not blow up.

#2 Get your facts straight I Spun a rod bearing.

#3 Do your research, This is the 2nd most common failure on a TBSS regardless if it is tuned or modified. (2nd to the weak 4L70E Trans)

#4 You would also know from said researching that Stock TBSS’s with 3k on them have had this same exact thing happen to them! I am at 82k this is no surprise to me that it happened I have fully expected it since I bought the truck.

#5 Ryans car (Seans Brother) - They do not know what caused it to blow up yet as it has not been torn apart. And the “Tuner” has already been in contact with them and they were told the day after it happened to call him after he heard about it.

SO please next time you decide to throw my business out there ask me for the story first like the mature people did when they found out about it. kthx.

FYI a “spun bearing” is no different then popping a piston. These both fall under the “blown motor” catagorys. Sorry to break it to ya, but thats the truth.

Can you drive around night and day, with a spun bearing? No. So, how does this NOT make it a blown motor?

sorry you had to be woken up bright and early to hear that what I was told, was wrong (although its not that wrong because I was told your shit blew up, which it did)

[K20power]

Yeahh since when is a spun bearing “just a minor issue” that can be quickly fixed and nothing else is damaged…? It’s considered blown up.

Not standing up for any tuner here but im going to have to say a spun bearing and shooting a rod through the block is NOT tuning related. Yes it can happen…but not common. I could see if we were talking about a melted piston here or something but were not

[Alpine]

I guess if you run overly advanced ignition timing it can and will put additional stress on the con rods/bearings, but usually the car will knock and the computer will RETARD the timing anyway.

Oh, topic: Travis’ Evo moves. I don’t see this Camaro even coming remotely close to winning any type of race unless it’s running a 200 shot and is running a tire that stretches the width of the northway.

wana melt pistons tonight? im cold

@kdubs

I sent a link to this thread to Brandon at Fast Motorsports as I felt he deserved to look it over… Here were his responses…

Motor is not out of the car yet so cause of that the failure is unknown to anyone including the owner of the car

Simply put on spray if your car was knocking it would have popped long ago.

Since we are talking about your car now your tune before was basically stock. The fuel injector size and PE table were changed that was it. Your maf, ve, timing and raf all were stone stock. Your car wouldn’t idle, had nasty cold starts, would surge, would buck, and would stall.

Spun a rod bearing just like many of the awd trucks do. For reference here are just a few threads if your interested

Hello, nice to meet you to sir. For your information and everyone on this board in 9 years of tuning this would only be the 3rd engine failure I have seen outside of the tbss rod bearing failures. If you include those then it would be a total of 6. First engine failure was from a drilled nitrous jet being used. Second failure was from a motor being hydro locked in the flooding we had around here a few years back. Third now the unknown issue currently with Ryan’s car.

An ls motor is very efficient compared to a small block or lt motor. They don’t need a ton of timing to make power. So if by going from lets say 21 degrees to 25 degrees and you only pick up 3hp its not worth having that timing in there. Most of all reading spark plugs will tell you what you need to put at the motor. When we all were on the dyno I was checking plugs from both sides of the motor looking for the fuel ring and the timing mark all which were well in line.

I would like to point out as well since Andrew does not have a timing controller on the car that the tune had to store the advance for the amount of spray he would be running. So even though it’s in the 21-23 degree range in the tune it needs to be that way for the spray. If it had a timing controller it would have been 3-4 degrees higher. Also, as any tuner in the lsx world will admit to the power loss from those 3-4 degrees of timing would be 5-7hp max if you are close to MBT.

Those are the exact tables straight from my laptop from Andrew’s car. NA fueling was commanded at 12.69:1 and timing was 21-23 at wot. Pulls were made as lean as 13.0:1 and rich as 12.3:1 to see where best power was made. Also NA the timing was taking up to 26 degrees and only 3 more HP was found. Since he has a larger cam that has more pumping losses they tend to like a touch more fuel and a little less timing.

Those are images from Ryan’s tune. Fueling was commanded at 12.71:1 and timing was set to 26-28 at WOT. Since the car had a smaller cam they do like a leaner mix and some more timing to make best power. From 23 to 26 degrees of timing I saw an increase of 15hp. I went up to 30 degrees of timing and only saw only 3hp. Also the timing mark was too far down the ground strap for my liking. Fuel mixtures from 12.5:1-13.0:1 were tried and the best was right in the middle.

It is well documented that the rod bearing failures in the tbss world are from oil starvation issues from the front sump oil pan. Even with adding an extra quart of oil to the sump I have documented oil pressure dropping from 45psi all the way down to 9psi at 3500rpm in first gear and not starting to recover until 4000rpm in second gear then by the shift point of 2-3 that it regains full pressure in the 55psi range. That is a ton of abnormal abuse the bearings are seeing from the lack of oil. It’s not a matter of if you will spin a bearing but a matter of when with those trucks.

I do agree it is very odd that 2 motors had major issues so close to each other but one failure is a known issue and the second is still yet to be determined. So as weird as they are they are unrelated.

I would like to thank you for pointing out nobody is perfect in this world and it’s very easy for people to start pointing fingers. Failures happen from time to time. It’s a matter of figuring out exactly what happened. Could it be tune related? Yes. Could it be a parts failure? Yes. Normally though if it was tune related it would have happened a little sooner than 6 months later even if the car isn’t driving much. The weather from when those two cars were tuned was on the cooler side in April and also since both were mass air flow systems even if the car did now start consuming more air that above 4000rpm the maf curve would handle the fueling adjustments since it is reading the literal amount of air going into the motor. A motor has a trend of airflow consumption so it’s not going to make a drastic change from one condition to the next.

Also, let’s look at this all logically for a second. A tuner such as myself would not leave a car running in a way that it would cause damage. It is my job to make sure that car is running well and will continue to run well. So it is in my best interest to make sure that the work I have done is correct. I, myself, along with every other tuner and shop across this country has had a problem here and there, just how the world works. However, it is interesting that as parts are used and begin to become worn that’s it’s always the tuners fault until proven otherwise.

thanks Brandon. This is exactly what I needed.

Like I said, I just heard a tiny bit of the whole story which is why I was thinking the way I was. I personally am happy with the way my car turned out, and it runs damn good on the bottle. I have also done 4 plug changes and havent had a single issue…

I was just caught in a “freaking out” at the moment thing I guess. I did NOT mean to stir up this mess…if I knew it was all going to be taken this way I wouldnt have mentioned anything.

LOL

and besides, I never said I was going to win. I clearly said I would like to see this happen because all the call outs lately and not seeing any type of action come from Travis for the 2 years I have been here. Dont worry, I know I am going to lose.

A tune can absolutely cause a spun bearing.

Like I said, it can happen but there are manny other things that can cause it to. There are was to tell if this was the tuner, how did the cylinder walls and pistons look on kdubs motor, was there signs of detention? Everyone is coming in here like they can tune a car themselves when they should be takin a step back and thinking before they talk. Joey your car blew up and so did stallmers. Is morgan a terrible tuner?, for sure his fault…

just from checking plugs you can tell if its detonating or not
