4l80e to six speed (cda009)

[Joemmahaffey1]

Ok here we go again as my original post didnt load or so it seems. I am a complete newb who bought the v2 to be able to do donor motor swaps. My first task is helping with a motor swap. A standard cab shortbed that has a 4.3 and will be getting a completely stock lq4. My buddy has already put the pedal and master cylinder in the truck and has the bellhousing conversion and clutch to run this 350z trans. strange I know but we are more fab guys entering ls world. So my question is how do I shut off the trans control completely so nothing is reported>? I pulled the 6.0 tune and deleted vats and want adress the TC side of things. So again i realize this is a strange build but It would be the same question if I wanted to run a powerglide or th350. Once I can get clarity on trans I can full flash the gen 3 pcm that is already in truck controlling the factory 4.3.


Im ready to get destroyed on this topic which I am down for but as long as it comes with an answer!

I think the easiest thing to do here would be to switch over to a 2001-2002 Camaro tune with a full flash, but with the LQ4 engine stuff segment swapped in. Then just change the ratios for the transmission in the Corvette's transmission segment, update the rear gearing, and I would think you'd be good to go. Just remember, you can only swap segments from PCMs with the same OS, which OS do you currently have? With the GenIII, 12212156 is the best in the sense that you can get COS5 which likely has a bunch of stuff you don't really need, but it does have the semi open loop tables which are pretty sweet. Nothing strange about the Z trans, lots of folks are also using the AR5 I believe it's called from the Colorado. People want stupid money for a 20+ year old T56 that still needs a rebuild.

Yep, run a manual OS and don't worry about it. Use a manual 02 Camaro tune, copy/paste the engine info from an 02 LQ4 tune so it'll be close then flash it.

Good point, if you can't find the correct OSs for a full engine segment swap you can always copy and paste that stuff over. Then again, I just found this gem over in the tune file depot. An LQ4 with 12212156 OS, boom.

Here's a link to a bunch of stock tunes, very useful when doing segment swaps and the like.

ok so now I think I am getting somewhere! awesome so lets keep passing those quarantine hours! I guess I should keep asking because the right group is here, I now have the lq4 with the correct operating system to swap with an 02 camaro's trans tune. luckily i think i can look up the segment swap otherwise we woulda been walking me through a cut and paste too because it sounds easy but....i dunno wat what point ur cutting I will admit Supercharged11 I have not looked at your suggested the site for an 02 camaro tune. excited to get response so I had to fire this back. I am going to look for an 02 camaro 6 speed tune. I will also make sure i got an idea on how to segment swap because yes we are that green here. I s it silly to ask why we are segment swapping the motor into the the camaro tune, Could I segment swap the camaros trans tune into the lq4 tune? And I understand it takes the same operating systems to be compatible without cut/pasting but can I full flash a gen 3 ecm with my built tune using the 12212156 Os No matter what OS it is currently running on? again thanks guys I really appreciate this

[Joemmahaffey1]

ok now we are getting somewhere! Supercharged 11 thank you for the link. I have downloaded the 02 camaro manuel tune and the lq4 tune with same os. Do i have to swap the lq4 into the camaro tune? or would segment swapping the trans from the camaro tune into the lq4 tune be the same thing? Also When I create the frankenstein tune using 12212156 will doing a full flash rewrite the OS that is currently on controller??

[Joemmahaffey1]

In addition, If i have an 02 silverado tune with a 4.8 and a manuel trans would the 4.8 tune run the 6.0 ? I feel like I have an ls1 tune with a manuel trans also. Would either of these actually run the truck. I suppose not unless they are 6 speeds but in general are tunes from different iron blocks ls's interchangeable?
thanks again

[Supercharged111]

You'll want to segment swap the LQ4 engine and engine diagnostic segments onto the Camaro tune. There's some underlying stuff in both that you can't see and it sounds like the Camaro would be the better base here. Of course if you find something in the future you can always redo it the other way. An iron block 5.3 will have different VE, timing, possibly injectors, startup, idle, etc. It'd probably run with or without quirks. I know in my racing series mods are very limited. Since a 5.3 is so much cheaper, we're allowed to use it in place of an aluminum 5.7 LS1, but with ZERO changes to the PCM. Not even allowed to tell the PCM it's now a 5.3 and not a 5.7. 5.0 Mustang guys can swap in 24# injectors and a Ford E cam. Again, no EECIV changes allowed. The cars seem to run OK, but I would overwhelmingly prefer to be able to clean some things up in cases like this.

[Joemmahaffey1]

wow this has been amazing help. i dont need to know exactly why the camaro tune is the better base but I found out how to segment swap the lq4 calibrations and diagnostics into the camaro file. I pulled 02 camaro manuel tune from the website you recommended (thanks again). When I open the tune in v7.5 it says in the calibration screen that it had a 4l80e? 23236 lemme know your thoughts please. I see that the 02 camaro comes with a dbc setup which works good in this case, however can you change a dbw to dbc by changing to "no" in platform parameters? does the comp know to use an Iac and tps?? seems unlikely to me. Another OS platform situation? I hope this has passed some quarintine time! now you know the 60./6 speed swap. I am to : 1. swap lq4 calibrations and diagnostics into the 02 camaro tune 2. delete vats and whatever else (2nd 02) he feels neccesary and full flash his controller with what i came up .with??

[Supercharged111]

I'll have to open the Camaro tune on my laptop, but once you segment swap the 6.0 engine segment into a true 6 speed Camaro tune it should come with all the the DBW stuff enabled for you. If you encounter issues with the DBW stuff, then maybe you just segment swap the manual trans and trans diagnostics into the truck tune at that point.

[Supercharged111]

That screenshot you posted looks like it's from an Express Van, here's a link to a 2002 Camaro with manual transmission.

Strange thing is that it says up front it's a manual, but has all the crap to run a 4L60E present to include its gear ratios. FWIW though, I just opened up my C5 Z06's stock tune and it's the same way so I guess I wouldn't sweat it. Segment swap the engine and engine diagnostics into the Camaro tune and see how that works out. Post 3 here goes over how to perform a segment swap.

You'll need to have an 80e calibration that uses the same OS as your 60e calibration.

Open the 60e calibration as your primary file, then load the 80e calibration as your alternate for comparison.

Go to the edit menu and "Copy Entire Segment". I would assume that you would need to copy both the trans calibration and the trans diagnostics.

Are you holding classes anywhere>? now that i am learning to configure a comp lets talk about making more power! haha maybe on phase 2. Okso it sounds like in this world of tunes you might have to try a couple things to get it to the drivers liking and to get it operate correctly without codes. Once i use a vin on his truck I can re full flash as many times as I want>? it doesn't seem to me to be alot of risk into flashing a tune that doesnt work and in reality you dont think ur gonna use just to see what reactions you receive? and just to understand you corvette tune when opened shows an auto trans as well? like my 02 camaro screenshot?> i guess it doesnt matter because you linked the tune I see clearly as manuel so that will be the tune I use I just wondering if you cant always trust what ur reading? I cant believe how much you helped move this project along. I have a feeling your stuck with a newb when you got time. How can I document the build on here to keep you updated on progress? Now I wait for him to do his end and hopefully swing in at the end and look like I know what i am doing getting it to run!

hey man Supercharged111 . The last weeks have been a weird time.... sure as with all. however my buddy hit me up and is transplanting motor now I gotta come thru with my first tune/full flash on something i bought a year ago and havent had ppl in need enough to use it. Wanted to say thanks for the help and Im on the clock so ill get to a finishing a product here for him and hope for the best. thanks for the help and ill post results and prolly more ?'s to come but if you didnt offer this I literally wouldn't have any basis on how to do this

Let us know how it turns out and if you need any more help.

[Joemmahaffey1]

hey so back for more help as i look to flash this weekend. for some reason he has gotten shy about using the 4.3 computer. I dont think he understands that i have his 4.3 tune saved and could alwats put it back in if he needs it but whatever. his question to me is why can we not use my tune in the 6.0 computer that came out his donor 2500 and use it possible to switch it in the 1500 that was original a 6 cylinder. I will of benefited from putting the tune together because of the os and dbc platform. however when you need to remove vats from my understanding it is triggered by the pcm not recognizing the bcm. this always made me think the bcm was integraterd into the vehicles pcm. This makes me wonder. Are gen 3 controllers interchangeable between trucks? Can you just take a donor comp. swap in the tunes you need to make your motor and trans work but what becomes of the vin>? and will the rest of the truck bcm side of things function correctly? in this case i think he fears full flashing the computer that came stock in the truck because he doesnt think i know what im doing. so is his donor pcm is flashed with the tune you helped me make will it operate the truck properly /

[Joemmahaffey1]

hey i just wanted to post again before i use up time as i have appreciated. I researched the year and color differences for pcm color and year changes. I have matched a red and blue computer truck plugs to a red and blue computer I had. His research told him to use a 99-02 engine harness for the tps/iac side of management. the donor comp I got is a 4.8 out of a 99. since he doesnt trust me with his stock computer because I guess if I crash and burn he can pony up the 300-400 to pay somone to do it. So I will vin and flash my donor 4.8 with the camaro tune with lq4 segment swap. if you got a minute to explain if I should bother to try and vin the new pcm to his truck? thanks

[Joemmahaffey1]

so here we are... there has been so many liitle changes with wiring harness changes to accomplish the v8 swap in truck and have it be dbc. long story short he had to use a gen 3 controller from the van with dbc capabilities. So the tune we created wouldn't load into a gen 3 controller with the 02 camaro format we started with. I flashed the van comp with 6.0 parameters and runs but is in extreme limp mode because the trans pressure sensor? So now can we source an 03 or newer trans tune to run his 6 speed with and get it on the same van platform? I was starting with a 6.0 van platform with operating system 12587603. Its a 6.0 and I was goin to switch the electric throttle to "no". We have wasted some vins and the van computer and operating system is the only on that allowed his gauges to function. So can we swap a trans tune into that van platform>?? I cant believe how deep into this we are. Cant see the light thanks if your out there
