We were asked not to post out thoughts in the BLOWN MOTOR POST unless you have had problems so here are my thoughts.

Look at MOST of the mods. High Boost with stock plugs. Everyone should pay attention to this.You should change your plugs ANYTHING over stock. You SHOULD Reguarly check your plugs to make sure they are burning ok and not getting loose. Prevenitive Maintenance is the key guys. And alot of people have like 4 or 5 posts and are knocking tuners? Are you scared of something? Speak your mind!!! I hate fake liars and its easy to tell who is lying on here. I dont wish anyone any harm but you gota do your part to make things work. It does not take a GREAT auto mechanic do do checks to see how their TOY is working... Here is the post that I am refering to... https://www.f150online.com/forums/sh...threadid=64249

 

 

No offense to JL, but your chips seem to be the most common one for blown motors.


I was wondering that when I was reading the post, it boggled my mind.

 

These trucks don't lend themselves to easy inspections, but do require constant checks for those of us that push them this hard. If you do not intend to do your home work expect to fail. I have been a Lightning owner since 6-99 and have been trying all sorts of things to make the truck quicker. I for one would not be shocked if my motor blew, but do try and keep a good eye on it and not over do any of the mods available. Keeping everything in balance has always been my #1 goal so performance would be at it best.
Guy's, mod your trucks but not just because everyone else is doing it but because you want to and intend to take care of it on a regular bases. Motors are going to let go, no stopping that, but keeping a good eye on all will help.

 

True alot of the guys there have JL chips. But, look at the mods with them. Not alot of good combos there. I for one have seen with my own eyes JL's Chips on the Dyno & on a Ford Scanner. I also saw with my own eyes OTHER TUNERS chips being sent to JL for a reburn. Even from some people on these boards. JL has been good to me, and so has Sal(PSP) & Mark(LFP). I have not delt with Jim(JDM) yet so I can not comment on him.

I will say this.. There are alot of guys on here with fake names and statements that want to hurt tuners other than JDM....

I independantly confirmed the identity of all but one of the posters on that thread.... There are no posers or repeat posters with one possible exception... One possible issue is not enough to scew the data..

I think one big problem with this whole motor subject is that there are really two types of "blowing" your motor, and they are being discussed as one subject. There are the people who are really "Blowing" thier motors, i.e.- broken bottom end parts. And then there are people who are "frying" thier motors, i.e.- burned plugs, burned valves, damaged pistons. These are really two different issues, with different causes, and they should be in two seperate threads.

 

Exactly Sal. There is a big difference between someone who blows there bottom end after running 100's of pounds of nitrous through there engine and someone who installs a chip and pulley and burns the motor up! 2 completely different issues!

In defense of JL, he does not personally build the programs for the Diablo chips he sells. Diablo does not have the software to allow JL to actually build his own programs. I have heard that Diablo will soon have this ability and JL will be able to make his own programs which should help with this problem. I tried to purchase a nitrous prgram from Diablo when there chips first came out for the L's and when I called Diablo and requested to speak to their Lightning tuner, I was told that I couldn't because I wasn't a dealer. That was all I needed to hear. I personally feel safer running a chip from a tuner who virutally deals with the L's on a daily basis rather than from someone in Florida who I can not contact or know anything about!

My 2cents!

 

How does spark plug problems cause the engine to "blow"?

 

Well said Sal. Blowing a motor can be very complicated, or at times, can be very simple!! Bottom line, like any thing else in life, you have to look at the individual factors of each case. While at first I too was concerned that most of the blown motors had JL chips, I immediately considered whether a too lean chip would cause these problems. Could be, but then there could be other problems, but I am definately not an expert in this matter. One thing is for sure, resist the temptation to over "generalize" potential problems and causes.

For Pete's sake, we are generating over 400 hp on these engines and we are surprised that things are breaking?!? Just consider 5 years ago, a 400 hp engine in a relatively stock engine was unheard of (except the Viper). Hey, hp is horse POWER and it tends to break weak links!!

 

No matter how the question was worded or described someone would take exception to it... All the posters had signiicant issues with their drive train. Since there are ONLY 11 posts it shouldnt be too hard to break the data down to suit your preference without starting a whole subthread

Hmmm, They have 12 post's on the blown engine thread. Think about it fellas, those arent bad numbers considering the what,15-20 thousand(give or take a few) G2 Lightnings produced since '99!! And some of those could have been prevented given the circumstances.
When I worked for a local Gm dealership, we saw several blown LS1 engines. Whether it was from NOS(it was obvious thats what caused some of them, but we couldnt PROVE it.) are just plain old abuse, they always replaced the engines, unlike Ford. If you push any engine hard enough, something will break. Tolerances in identical engines are not the same! Ive seen it many times working in the shop for GM. We had several Formulas and T/A's on the lot at any given time, and some of them wouldnt run for s***, then there were some that were freaks and just haul a$$! We never could figure it out. If my engine lets go, it wont surprise me. I will take it to the dealer for warranty, if they void it, so be it, Ill fix it myself!

 

I havent blown my lightning motor...
