So it seems i finally have an investor.
My main hurdle to having a turbo LSx was the tune costing an unfair and unreasonable $400.
My solution is to sell copies of my tune, loaded into spare pcms.
0411 pcms can be had for under $50, and i would love to sell loaded ones for 150, but because of my investor needing a profit, it will probably be more like $200 each.
The idea is i will assemble a matched combination of affordable parts, unlike Denmah / Sloppy Mechanics ( those overkill injectors are way overpriced, for example )
Then get my car dyno-tuned. Then i load my tune into about 20 spare 0411s, and sell each 0411.
Then whenever someone wants to assemble a turbo LSx on a tight budget, they just gather the exact same parts I chose, and they save on injectors, and they save a couple hundred dollars on a tune that they can rest assured will be a perfect match.
Sweet, right? Elegant. Beautiful, even.

 

That is a terrible idea for a boosted car

400$ for a good competent tune is very reasonable. I suggest saving up

 

I agree, terrible idea. Sure you may get a few guys that dont understand how anything works buying a tune/pcm. They will load it in the car, blow the car up then bash you. Just because two cars have the same setup doesn't mean they are going to run identical. So many variables. I'm going through this with a friend. We have similar setups so I told him he can take my tune as a base. He cant even get around the corner without the car leaning out.

$400 for a tune that will save the car is not unreasonable to me.

Obviously neither of you understood, over on ls1tech i already have a guy trying to invest in it. Those who understand will be all over this. They wont care if there are 20 other guys out there with the exact same combination of parts running the exact ssme dyno tune. And as long as they stick to the recipe, none wil ll be at risk of hurting their engines. So hush and get out.

 

Youre just bitter that you couldnt figure out a way to avoid paying too much for your tunes.

 

Trust me i understand. Every lsx guy wants a cookie cutter setup and bolt and play deal

Trouble is it doesnt work like that and you will find out.

Main thing is not everyone will abide by the combo rules you are selling. "Oh this cam is similar" oh i have 60 lb siemens, thats similar to their brand injector rating

That will happen. And it may be different enough to not behave the same way

Other thing is not everyones base motor they pulled out the junk yard runs the same. You hear of all these guys on the net running 8's and 9's on stock bottom ends. But in the real world, theres not as many as it seems. Most guys arent seeing that result. What isnt being told alot of the time is those motors have stock rods pistons and crank, but have been thoroughly cleaned disassembled and reassembled after setting up bearing clearances and ring gaps built for boost.
Also the motor i pull from a 05 truck with 40,000 miles may not be the same condition as the next guys '11 truck with 230,000 miles. Ring seal, bearing wear, etc. all effect the power of the motor to start, and how it may handle boost and what it may want for fueling.


If joe smoe isnt doing it 100% exact with the identical motor then it may require a different tune up.
Its a good idea if you were selling a turnkey crate motor deal using a sealed crate motor to start. Something where 100% of the combo is in your hands, in your control

 

No i do my own tunes and work close with shops around here to know what a good tune takes to do, and its worth every penny of 400-500$. If you cant pay to play the game then i'm sorry, expect less than satisfactory results

 

This is literally the dumbest thing i've ever read. 400$ in neither unfair or unreasonable for a custom tune for a boosted ls application. Tune's dont just transfer over, unles the combo is nearly identical right down to the turbo, charge piping, hotside, intercooler, engine size, cam specs, compression ratio, intake manifold, injector brand, injector size, base fuel pressure, etc... I tune all my own cars and know DAM WELL that for the time I spend that 400 is more than fair. Are you going to be liable for this tune that you sell to others when it isnt anywhere near right for their combo and torches their engine? If your investor thinks this is a good idea then he isnt very smart either.

 

No, not sweet at all. You need to understand that there are other things that affect kPa/LV8 location, it isn't just a matter of injector size and air flow, as weight and gearing also affect where the VE will hover, and if the source tune is lean in that area, then it is game over for the party that bought a copy...

 

I wish I could get a boosted tune for $400 lol. Good shops around here are $600+ for boosted. Like everything in life you get what you pay for. There are plenty of places doing mail order tunes as well if you didn't know. I think most are around $100 for the file. Good luck.

 

I paid so much for mine....seeing I tuned mine myself.

 

A great point here.

 

Since all of you are too anti-intelligent, I will just fabricate an enclosure for my Edelbrock 750 and do a blow-through turbo on my Vortec 454 and leave all your LSx junk in my dust. Goodbye tgo. Not one of you is worth knowing.

 

Oh please. What are you 15? Grow up and get your head out of your **** and you might learn something

 

Damn you guys made him all butthurt and he ran off

 

Just goes to show you dont have the slightest clue. i'll rip the f***ing paint off your car with my SBE 5.3.

 

Get a canned tune from him, you'd be faster

 

but how will I plug the 411 pcm into my holley efi harness??!?

 

Its just a repin lolz

 

well hot dam, where do I sign up for this f***ing magical canned tune so I can sell my 2k dominator ECU?!?!?!

 

PMS much?

 

Holy **** I needed a good laugh tonight. bye Felicia

 

Threads like these make me wish the Non-Tech board was still around.

 

Wait until he sees how much the licensing for all those JY PCMs will cost

Canned tunes perform like... canned tunes. Any Blower kit will have this. The first thing anyone will suggest is a proper dyno tune

Besides, who wants to copy a shitty JY thrown together build to the T?

It was a good laugh for a sunday

 

I dont have much to add to this conversation, but I just wanted to chime in to say this was a hilarious exchange

People who cant take legitimate criticisms from people who know what they are talking about is too funny. Even better that he got butt hurt and ran off. Always kinda thought cosmick was a troll anyways....

 

That's was a good read and a good chuckle on a slow Sunday.
Isn't this the same guy who was going to run some oddball Isuzu axle and a sm465 in his mystical 1000hp 3rd Gen too?

 

Yes

 

Missed the previous posts... just... wow.

I paid $450 for my first tune, and that guy screwed me over big time. Tuned it in under

 

Wow... cut me off and posted it. Weird.

Tuned it in under 1 hour though. Riiiight. Bought the software myself after that and am learning.

Throwing a hissy fit made the thread.

 

This is just a sad thread.

While Im all for the thought of a member trying to create a budget turbo ls kit for thirdgens I think is a great thing for the community to make more badass cars and brings 3rdgens back to life. The tune is an area better left to owner of the car to have done locally at a reputable shop for many reasons already mentioned.

Now If Cosmick had said that he would include his tune as a base to get the car running and driveable for lets say $100-150..whatever a mail order tune would be plus the cost of the ecm then that would be more acceptable.But you would have to have an extremely similar setup.

 

I was trying to sell PCMs already loaded with the turbo tune, tuned for not similar combos, but an exactly identical combo. This part isn't new. The new part was the exact combination, being the specific parts that give dramatic power at the lowest cost. Far cheaper than Sloppy Mechanics, as the closest example. I know how to make it work, the technical aspects. But it only works if others join in rather than baseless bashing. And I thought the concept would sell itself. Emissions legal 600 HP with 30 mpg. The sad part was all the haters. So I changed tracks, going with a cheaper and easier blow-through-carburetor / turbo build of a 98 Vortec 454. Gonna take some tall gearing to get 30 mpg on one careful attempt, and it may never be emissions- legal, but huge power cheap is the most important thing. Always will be.

 

 

Hey he is back, when are you starting the 454 build thread I want to see that?

 

I'd be interested too. Always nice to read these diy threads.
